How to Camouflage Solar Panels in a Residential Environment

Posted by SEPCO

9/14/15 10:00 AM

When homeowners are first approached about putting solar panels on their house, a number of concerns inevitably pop up, ranging from cost to installation to the appearance on an otherwise unblemished roof. While the first two obstacles are becoming easier by the day, with a bit of advance planning, your solar panels can be made practically invisible from all but the planes passing overhead. 

Perhaps the most obvious route to integrating your solar cells with the natural world is to surround them with existing foliage, while maintaining sun exposure. Consider installing them near the tops of trees or shrubs in the backyard, facing away from the street. 

The cardinal direction of the street as it relates to your house can also make a difference. For maximum sun exposure, solar panels should face south, so if this happens to be the side away from the road, none but the neighbors behind you will see your panels. Also consider using a secondary part of your roof, such as the garage roof, that may be in a more discreet location. 

Another option, recommended by the experts at Solar Power Authority, is to use solar enabled native building materials, such as solar shingles, instead of external panels on the roof of your house. Because solar shingles are specifically designed to blend in with a roof as normal shingles would, they do not stand out in the same way.

Solar lights are also an option for those interested in using solar power on a smaller scale. Because outdoor lamps often draw large amounts of power, this can result in significant savings. These too are often designed to blend in like a conventional lamp would, with the panels hidden directly on the top. 

One recent technological innovation makes hiding solar cells significantly easier. According to Swiss research firm CSEM, cells can now be made without a visible gap, meaning that they can be dyed a pure color or whatever the natural color of their environment. Previously, it was thought that they needed a "join" in between cells connected in series. In practical terms, solar panels can now be built into walls and roofs alike, while remaining indistinguishable from the structure around them. 

When evaluating the best possible place to install your solar panels, it is important to keep perspective on the necessity of hiding them. After all, we once considered power lines an insufferable eyesore, and today we kvetch about the cell phone towers with comically obvious fake branches running down their telephone pole-shaped trunk. Your solar panels can blend in with the environment of your home much more seamlessly, and with all the environmental benefits of the trees they mimic.

Benefits of Renewable Energy

Posted by SEPCO

6/22/15 10:00 AM

Benefits of Renewable EnergyRenewable Energy and Green Power Energy efficiency opportunities have been available to some facilities across the county and some facilities may want to consider going green. It is studied that renewable energy is referenced as electricity distributed from energy sources in the form of Wind, Solar, Geothermal, Hydro and Biomass. These energies are abundant and based on energy flows that are replenished by natural process and does not become depleted when use, like fossil fuel or nuclear.

Renewable energy has unique costs and benefits than the conventional sources. Studies show that much higher level of renewable energy can be achieved while substantially reducing global warming emissions. Green power is more environmental, friendly, safer and healthy, if all the states embark on sound plan to created and maximize green, renewable energy and energy efficiency.

Benefits of Renewable Energy:

Renewable energy improves health and environmental quality. Electricity generated from renewable energy rather than fossil fuels offer significant public health, environmental and economic benefits.

Renewable energy will significantly reduce premature mortality, lost work days and overall health care costs. Like the fossil fuels, they emit pollutions to our air and water which has been linked to breathing problems, neurological damaged heart attacks and cancer.

Green power is huge and in-exhaustible in supply, throughout the world, strong winds, sunny skies, plant residues, heat from the earth and fast moving tide can each provide a huge and consistent energy replenished supply. The diversity sources of renewable energy have immense potential to offer all the electricity a nation needs many times over if properly harnessed and managed as well.

Another important factor in using renewable energy sources is to help reduce the negative environmental effects associated with non-renewable energy sources such as coal and natural gas. Willingness to use a renewable energy source will not only decipher into cost savings for you over the long haul, but will also help protect the environment from the risks of fossil fuel emissions of non-renewable energy sources.

Economic Benefits:

Harnessing renewable energy is more labor intensive, as compared to fossil fuels, which is typically mechanized and capital intensive. On average, it creates a lot of jobs for each unit of electricity generated from renewable sources than fossil fuels. Increasing renewable energy has real potential to continue still job addition and creation.

Green energy in 2014 supports thousands of jobs in various capacities in the United State, for example Wind and Solar industries. These job gains would be enough on their own to reduce the unemployment rate in today’s economy by about two full percentage points, even after taking into full account the inevitable job losses in conventional fossil fuel sectors of the U.S. economy as they contract.

5 Reasons to Install Solar Panels

Posted by SEPCO

4/20/15 10:00 AM


Nowadays sustainable use of energy is being focused a lot. With that usage of renewable and unconventional energy resources are more concentrated upon as compared to the non-renewable and conventional energy resources. If you haven’t installed solar panels yet, below listed are a few reasons to get one as soon as possible:

Increases the value of your house
If you are planning to sell your house in future or may be today, experts say that solar panels increases the value of the house by 6%. It is a lot easier to sell a house with solar panels as compared to the ones that are without it. The main reason behind it is that the new family, which will live in the house, would be free from the high electricity bills. Moreover, they will also enjoy the feed in tariff regimes. When the rates of electricity are increasing every year, a house with a solar panel is no less than a heaven.

Reduces pollution in the environment

Many say that they cannot alone change the scenario of increased pollution in the environment. Solar panels have changed this mentality of people. If one uses solar panel on their house, they will reduce up to thirty tonnes of carbon dioxide over the system’s lifetime. Thus, your bit will be surely counted and would definitely bring change in the environment. 

Low maintenance

Solar panels provide the user with low upkeep. They don’t require much maintenance just keep them free from snow and leaves other than that solar panels will never bother you. Most companies provide twenty-five years warranty for the solar panels.

Best investment

No other schemes or saving accounts will provide such return rates than the installation of solar panels. It is ensured that for twenty-five years or more your installation is tax free and installation guaranteed.

No drawbacks

One of the best reasons to install solar panels in your offices, homes, schools etc. is that they have no drawbacks or side effects. All you need to do is enjoy the perks conferred by the government for installing them.

Aforementioned points are some of the reasons to get your place equipped with solar panels. If you haven’t installed them yet, it is a good time to look into it as the prices of solar panels have dropped drastically in the last couple of years. Moreover, with so many money saving benefits, install solar panels and enjoy electricity at low rates while saving the environment as well as money in the long run.

Making a Switch: Is Your Business Able to Switch Electric Providers?

Posted by SEPCO

9/18/14 9:30 AM

SwitchSwitching electricity providers is possible now, but many businesses are hesitant because of some of the roadblocks that have been presented for other companies. Research is essential to understanding the plan and ensuring that you get good quality service from your provider. Here's what you need to know if you're considering switching: 

1. Only Customers of Licensed Retailers Can Switch

Your choice of electricity companies are only limited by the number of retailers available. If you're in an area with only one provider, then you have no choice but to select that provider. Some retailers will only supply to business customers. This could be an advantage for business owners. If you do have a choice, you're considered a "contestable customer."

2. Must Meet Certain Criteria to Switch

To switch, you must use more than 50 MWh of electricity per year. You may also qualify if your distributor is not Western Power. You cannot combine the amount of electricity you are using at each property to make yourself eligible as a contestable customer. If you use less than 50 MWh per year or pay less than $12,600 per year, and you are already connected to Western Power's network, you will not be allowed to switch. Any non-contestable customer in the SWIS network will receive electricity from Synergy. 

3. Find an Approved Provider

You must select a retailer that's been approved by the Economic Regulation Authority (ERA). The ERA website will list all of the retailers that have been approved to provide electricity to consumers. Contact these retailers when you decide which one is best for you. The new retailer will arrange the transfer on your behalf. Once you switch, your old retailer may not bill you for any electricity used. 

4. Always Ensure That You're Getting the Best Rate Possible

You want to ensure that you get the best rate possible at all times when you switch electricity providers, therefore shopping around is crucial. When you find the best rate, follow the procedures to switch. Most companies will require that you enter into a contract for a specified period of time. Once that time lapses, you're welcome to find another provider. 

Keep in mind that surveys have been conducted demonstrating the sentiment regarding this issue. When a group was surveyed, 413 had changed their power companies in the past three years, but only 52 percent were confident that they made the right choice. Comparing offers is not always easy, and there may be some hidden costs that you're unaware of until the bill comes. 

Every bill may have off-peak offers and peak-usage offers. Some companies offer discounts for on-time payments and others do not. You must know how you'll be affected before you make a decision. 

5. Be Aware of Unauthorised Switches

Five percent of people have been switched from one provider to another without authorization. For this reason, many people are sceptical of sales people when they knock on their doors and request a change. You must know at all times what the terms are and ensure that no person switches you without your permission. 

6. Most People Switch When They Move

Most people don't consider switching providers until they move. If they move to another location, they have more or sometimes, fewer options available. While a move may force you to switch providers, you should always perform due diligence to ensure that you are getting the best deal possible.

7. Beware of Penalties

If you're renting your building or apartment, be sure that your rental agreement coincides with the length of your electricity contract. If you break the contract before the agreed upon time, you may have to pay exorbitant fees. If you want to avoid fees and problems, you should ensure that if you are renting for a year, your contract with the electricity company should not exceed one year. 

Making the Switch Can Be Profitable 

If you remove all of the caveats, switching can be profitable. You can save more money that can be re-invested into your business. This is desirable to most people in this situation. While there are some organisations available to help you, they are more focused on helping residential consumers. Find the organisations that are willing to help you and avoid those that may switch you without your knowledge. In general, do not sign anything until you read it fully because you may be switching your electricity service without knowing it. Switching can be a good practice if it's executed properly.

Harness the Sun to Power Your Home

Posted by SEPCO

9/9/14 9:30 AM

SunThere has been a growing trend in recent years towards clean, renewable energy. Many consumers have explored the benefits of meeting some or all of their energy needs through renewable energy, such as wind or solar energy. One of the most common and popular options is the installation of home solar panels. When done properly, these solar panels can generate a large amount of electricity, greatly reducing the bill being paid to the electric company.

Over time, it is very possible for the investment in solar energy to pay for itself and more, all while being clean and renewable. The first consideration when looking in to solar panels is the upfront cost. Depending on the size of your house and the amount of energy you are looking to produce, this can be a sizable investment. In addition to investigating the cost of the panels themselves, you will want to look in to the cost of getting the panels installed on your roof and connected to your home's electrical system.

While it is possible to do the installation yourself, most consumers will want to hire professionals to make sure the job is done correctly the first time. The amount you pay for a professional installation can be significantly less than having to redo the project later. In certain areas, especially northern latitudes which gets fewer hours of sunlight, you may not generate enough energy through solar for it to be your only source of energy. Be sure to carefully monitor your energy usage to determine if you can get by with just solar energy, and reach out to other homeowners who have made the switch to solar. They will be able to give you an estimate on how much energy you can expect to generate through solar panels.

Other homeowners can also be an excellent resource on where to buy panels and how to install them. If need be, you can also look in to options such as wind, or see if your electric company offers any partial-year options; you may be able to use solar energy throughout the summer and just need the extra electricity during the winter months.

In addition to the actual installation, you will want to look in to any laws in your area regarding solar panels for homes. While solar panels are becoming increasingly prevalent, there may be rules or regulations which can come in to play in your particular case, so you will want to be aware of them. In addition to any laws, you will want to check with any homeowners association, landlord, or other entity which has any say in your home to make sure you can install your solar panels. It is also worth looking in to any tax credits you may qualify for by switching to solar energy.

6 Questions to Ask Before Going Solar

Posted by SEPCO

7/24/14 9:30 AM

Before_Going_SolarAs with any investment, purchasing solar panels for your home is a decision that shouldn't be made lightly. You will need to consider many factors and avoid the numerous pitfalls. By hiring the right company and asking the right questions, you'll be able to benefit greatly from solar panels.

It is important to decide if having solar panels installed on your house is the right decision for your situation wants and needs. Solar panels offer many impressive benefits, but there are other factors to consider. We take a look at what questions you should ask before you make the switch, and the pitfalls to avoid.

1. Is the company and brand of solar panels you’re considering reputable?

You should ask the companies if they use a reputable brand of solar panels. If you can't find much information about the brand or manufacturer, then you shouldn't use those particular types of solar panels. The solar company you go through should have fully trained employees, with skilled technicians and installers to help you with the process.

Don’t be afraid to ask how long the company has been in the business. An established company that has served many customers with a portfolio of work and testimonials tends to be a company that you’re able to trust and relay on. Years of satisfied customers means good work and a reputable company will be more than willing to show off their good work and previous clientele.

In the solar business, there are unfortunately many people trying to sell cheaply made solar panels and rip customers off. Opting for a cheaper solution or a company that doesn’t appear reputable will only lead to inexperienced installer doing the job for you, additional and costly repairs, and a service that won’t follow up on you and the product after it’s installed.

By concentrating on quality above anything else and working with the right company, you’ll be able to determine whether solar panels is a good investment for your home and avoid costly mistakes.

2. Should you lease or buy solar panels?

Depending on your goals, there difference between purchasing your own solar panels and leasing can vary dramatically. Because every homeowner has different goals, the “right” payment option for each person can change.

Whilst the initial cost of purchasing solar panels yourself can be expensive, most homeowners prefer to do so. The ongoing savings on power bills solar panels offer ensure the initial expensive of them are paid off in 10 years, depending on the home. Cash rebates can also reduce the cost of the system by 10%-50% and with government incentives in place, tends to be the better option for most people.

For those that choose to lease solar panels, the long-term financial benefits will be less than those of purchasing. The advantage though is that the upfront costs are lower and any maintenance or repairs become responsibility of the leasing company, not you. Lease terms are generally for 20 years but some can range from 10-20. To find out what option is best for you, it’s best to speak with the solar power company about your specific situation.

3. Does the cost outweigh the benefits?

There is no point in investing in something that doesn’t serve you and so weighing up the cost and benefits is crucial. For homeowners that haven’t yet experienced the benefits of solar power firsthand, making the switch can be fairly daunting with the costs involved.

On the brightside though, (pun intended) the savings through solar power are significant – not to mention the environmental impact it has too. Over the last few years, everyone has fallen victim to the ongoing utility costs on the rise and we’re all looking for ways to cut down on how much we spend. Installing solar powers and taking advantage of the sun’s energy is one of the best ways to do this.

Government incentives and tax breaks sweeten the deal for homeowners wanting solar a little more, the system and panels add value to your home and the sustainable energy is a growing and beneficial industry. Whilst the initial cost can seem like disadvantage, solar power systems are one investment that will pay off and give years of enjoyment. Always ask your solar company to go through the individual costs with you. You can bring a copy of the last few utility bills too to determine if the cost will really outweigh the benefits in your home.

4. What is the type of panel mounting system that’ll be used?

Understanding the type of panel mounting system for your home, and the materials it’s made of will ensure you’re getting a durable system. Look for mounting systems that are made from either stainless steel or aluminium.

When solar panels are installed, the mounting system is what balances everything and holds it into place. Check with the company whether roof mounts, ground mounts or pole mounts would be best for your home and how this can impact on the system quality and price. The most common style of system mounting is on the roof and this is held together by metal brackets between the solar panels and roof to ensure the panels do not overheat.

5. Will you be able to produce enough power in your location?

The biggest advantage of solar power is that it relies on the sun for its power source, making it absolutely free. But, this would be pretty useless if your sun gets little to no sun right? Cloudy days can be an issue and locations that suffer all year round winters can be very indecisive about making the switch.

To accommodate for lack of sun, a large number of solar powers can be needed to produce greater amounts of electricity. This can require more roof space and money so it’s best to check with your company if this will affect you.  If you’re unsure, ask a reputable solar power company. Most companies will come to your home and conduct a site examination, including shade analysis which helps to determine whether solar is the best solution for you.

6. How long will the solar panels last for?

No homeowner wants to fork out money for an investment that won’t last the distance. This is why choosing a company that is reputable and trustworthy, and that uses quality a product is of the upmost importance. 

The lifespan of solar panels depends on several factors including the quality of the materials, and the specific manufacturer. Look for products that come with a long warranty, and this shows the manufactures commit and belief in the product. Companies that offer only a few years warranty on their products is best to stay away from, you should be looking at least 10 years.  A durable and reliable solar panel inverter and mounting system will last the distance.

How to Go Green without Really Trying

Posted by SEPCO

3/20/14 9:30 AM

Going green might seem like a complicated, cumbersome ideal that’s just a little too far out of your comfort zone. But it’s not something that has to take a lot of energy if you don’t have a lot to expend. Here are a few simple ways to go green without really trying.

Buy the Right Light Bulbs

This is a simple enough way to go a little greener all over the house. When you need to replace the light bulbs in your home, do yourself a favor and buy the florescent bulbs instead of the standard. They use 75% less energy than the incandescent variety and last much, much longer. They might be a little pricier up front, but they’ll more than pay for themselves—and your home will be a little greener for it.

Watch Water Use

Next time your showerheads need to be replaced, go for the low-flow option. You’ll conserve water in a big way, which will reduce your water bill as well as be environmentally friendly.

Teach your children to brush their teeth with the water off. Letting the water run while they scrub wastes an inordinate amount of water (up to five gallons a day) that could be saved simply by twisting the tap.

Only run the washing machine and dishwasher when they’re completely full. Half-loads aren’t as efficient, and you’ll end up running more loads than necessary.

Turn_off_ComputerTurn It Off

When you finish with your electronics for the night, turn them off. Unplug printers, computers, the TV, the DVD player, etc. If you can, plug them all into a power strip and then just switch it off every night before you go to bed. Turning off the devices all the way will prevent phantom power draw.

So instead of just leaving your laptop open and running, put it to sleep if you’re going to be away from it for a while. Turn off your phone at night instead of leaving it on all night to waste battery life. It will hardly take an effort on your part, and it’s just that much greener.                                                   

Permeable Paving

Your house can and should be just as green as your lifestyle. That isn’t to say that you need to install solar panels (although these are getting to be both more plausible and popular) or live in a tree house, but it can still be environmentally friendly. Next time you need to get your driveway repaved, consider forgoing the traditional asphalt or concrete and having permeable paving installed instead by your local paving company. Vancouver and Minnesota residents might need to have their roads repaved more often than cities in warmer climates, but the idea is the same no matter where you live.

Permeable paving is made of substances such as glass or permeable concrete that allow water to filter through it, keeping the surrounding lawns moist. They cool faster and require little maintenance. These materials are a little pricier but might be worth it in your quest for simple ways to go green.

Grow_a_GardenGrow a Garden

This idea takes a little more work, but if you plan on growing a garden anyway, you’re not any worse for wear. If you’ve been toying with the idea of planting a garden and just haven’t gotten around to it, make 2014 the year you try.

Gardens are an excellent way to “go green.” It doesn’t have to take up half your yard—any size, even a few tomato plants in pots, will make your meals a little healthier and reduce your “carbon footprint.”

Slow Down

When you drive, slow down a little. Higher speeds use more gas, so if you can afford to take a little extra time on your morning commute, it might be worth it. Checking the air pressure in your tires on a regular basis will also contribute to better gas mileage, as will keeping your air filters clean. Consider carpooling to work if you can to reduce emissions. None of these changes are life-altering, but the positive benefits add up.

Green Grocery Shopping

When you shop, spend the extra cash to buy natural or organic goods. They’re not as cheap as the produce grown with chemicals and hormones, but raising awareness of the health and environmental benefits of organically grown foods will make a difference.

Bring your own bags to carry your groceries. Reduce your use of paper and plastic bags (that only go straight to the landfills after you trash them at home). You can find cloth bags anywhere—many grocery stores even sell them in an effort to promote greener living.

Remember: your entire lifestyle doesn’t have to change to go green. Just be aware of the little things, and before you know it, you’ll be living just a little greener.

Recent Advances In Green Technology

Posted by SEPCO

3/13/14 9:30 AM


Attempting to make the world an improved and pollution-free place to live is not a straightforward task, and there are no settled principles. This is one of the tests we confront when making, executing and depending on different sources of energy; since no single source of energy is 100% 'clean'. Nonetheless, year-after-year we continue to make great strides along the difficult road to environmentally responsible energy sources.

As temperatures increases and population gets bigger, it’s clear that green engineering holds the way to the survival of Earth and all the species that live on it. Luckily, innovators all around the globe are endeavoring to create headways that will slow down or perhaps reduce the harm caused due to our over-reliance on fossil-powers.

According to Liberty Power, in a few cases, progress in green technology is dependent upon new discoveries and developments in science, physics and engineering. On the other hand, these advancements have been dead set generally by shift in thought processes. However, the thought of "green’’ is gaining popularity among people.

Several recent innovations are based on a century-old concept: that of using tidal power to generate electricity. Harnessing this renewable resource is rapidly becoming more practical and cost-effective. In the area of solar power, the use of copper-indium-gallium-selenide compounds in solar panels substantially increases the electrical power generating efficiency of these panels, plus the compounds make construction of the panels far easier. Bladeless wind turbine designs, based on the physics of ships sails, are expected to significantly reduce the number of deaths of birds and bats. Wind turbine technology is also continuing to evolve.

Some innovative advancement in green technology are as follows:

Marine Renewable Energy: Marine renewable energy works by harnessing the power of the ocean tides and currents; a continuous source of kinetic energy that can be used to power turbines which in turn produce electricity.

Solar Power: The sun provides enough energy in the form of light to supply the world with much more energy than we currently use globally.  Certain materials produce an electric current when exposed to light, and we can harness that current to generate electricity.

Algae-Based Biofuel: Algae is a simple organism ranging from single-celled to multi-cellular forms, and is typically thought of as a kind of plant due to its ability to perform photosynthesis. Using chemical and mechanical methods, oil can be extracted from algae and converted into fuel that acts in the same way as traditional petroleum fuels

Green Roof: Different countries are rapidly adopting idea of keeping their roofs planted with grass. It not only minimizes the heat effect but also reduce summer air conditioning usage.

With this transformation in green technology it is expected that we would not only be able to generate enough energy to fulfill our needs but also keep our planet safe and healthy.

Uses for Discharge Lamps

Posted by SEPCO

2/20/14 9:30 AM

lampWhat are some of the main uses for discharge lamps? This type of lamp involves an internal electrical discharge being created between two electrodes in a gas filled chamber; the level of intensity generated by a discharge lamp can vary, and can range from low level wattage bulbs through to extreme intensities that can be used for filling large areas with light. There are consequently many different uses for discharge lamps. It’s worth looking at these uses and the kinds of discharge lamps available, in more detail. 

Discharge lamps can be highly effective at maintaining luminosity for an extended period of time. Their applications extend across a range of domestic and commercial areas, and are affected by the type of gas being used. For example, mercury discharge lamps can provide particularly high levels of brightness for outdoor use, as can sodium lights, which can produce the orange glow seen on street lamps. Fluorescent lights can also be used to create low pressure and constant levels of luminosity. 

Some of the other common uses for discharge lamps include neon signs, whereby electrodes are used with tubing to create different letters and graphics; the process of creating a neon light is fairly complex, and involves glassblowing and setting up different colors. Neon or mercury vapor with some argon elements are the common components for these tubes, which require high voltage sources to be able to run efficiently. 

In the case of high intensity discharge lamps, outdoor arenas can be lighted using lamps with extremely high voltages; lumen bulbs can also be used for smaller outdoor areas and warehouses, as well as on roadways to create long lasting, high intensity illumination. Indoor gardening can also be aided by the use of low intensity discharge lamps, as can underwater diving and bicycle headlamps, with each use employing different levels of intensity. 

When setting up discharge lamps, it’s necessary to fit a control gear, which acts as a transformer for the amount of charge passing through a bulb or tube. There are several different types of control gears available, which can include inductive control gears and electronic control gears, with the latter capable of limiting the amount of current passing through a lamp. Control gears can similarly be used to ignite lamps, and represent an important way of maintaining health and safety levels for different devices. 

Whatever the usage of a discharge lamp, it’s crucial to be able to understand the different amounts of current and voltage that’s being used; high intensity discharge lamps are particularly susceptible to overheating, and should be carefully monitored using iron ballasts and control gears. Lamps that contain sodium and mercury can also present a toxic risk, and should be carefully disposed of if they break. To this end, it’s important to make sure that you read up on the different types of discharge lamps available from suppliers before committing to a particular power level.

23 Fun Facts about Solar Panels: All That You Need To Know

Posted by SEPCO

2/20/14 9:30 AM

solar-panel-house1. A solar panel is a set of photovoltaic modules, electrically connected assembly of solar cells. It is mounted on a supporting structure and can be used as a system to generate electricity in residential and commercial applications.

2. Each module ranges for 100 to 320 watts, rated by DC output power under STC. The efficiency determines the area of a module given the rated output.

3. Most of the installations contain multiple solar modules as a single module can produce a limited amount of energy.

4. A photovoltaic system includes an array of solar modules or a panel, an inverter, a solar tracer or battery, interconnecting wiring.

5. There are two types of solar panels: one produces electricity (photovoltaic), another collects heat (thermal).

6. Solar shingles look like ordinary asphalt roof shingles, and it can be used to avoid the unpleasant look of traditional panels.

7. Micro inverters perform better than normal panels for they work independently.

8. Solar modules use photons from sunlight to generate electricity through photovoltaic effect.

9. Cells are generally protected from moisture and mechanical damage.

10. Most of the solar modules are rigid; but based on thin film cells, semi-flexible ones are available.

11. The conducting wires are connected to each other and to rest of the system, to achieve a desired output voltage.

12. Bypass diodes are incorporated to maximize output of module sections.

13. Some recent designs include concentrators to enable the usage at high cost per unit area in a cost-effective way. Modules can also produce electricity from a range of frequencies of light beams, but this usually does not cover the entire range. They can give higher efficiencies when illuminated with monochromatic light.

14. Another design splits the light into different wavelength ranges and directs the beams onto different cells. The efficiency can be improved by studding the semiconductor surface.

15. Use of aluminum over gold or silver is preferred as it can bring down the cost and improve efficiency.

16. Monocrystalline and polycrystalline modules are currently produced for better performance.

17. Third generation prefers advanced thin-film cells. Compared to other solar technologies, they produce relatively high-efficiency conversion for low cost. They can be rigid or flexible. Flexible films are portable and lighter than rigid films, and resistant to breakage than ordinary crystalline ones.

18. The requirement for commercial and residential purpose is different. Residential needs can be packaged and are simple whereas commercial arena uses complex parabolic reflectors. This is becoming the dominant technology in different fields and aspects of life.

19. Smart solar modules make use of power optimizers and this technology maximizes the harvest of photovoltaic energy. Modules must withstand natural calamities. Manufacturers guarantee electricity production for 10 years at 90% and 25 years at 80% rated power output.

20. Nominal voltage allows users to assure the compatibility of a module with a system. The actual voltage output changes due to lightning and temperature. Some parts of it are recyclable including semiconductor materials, glass, and ferrous or non-ferrous substances.

21. 80% of incoming weight can be recovered from silicon based modules, 90% to 95% from non-silicon based modules are recovered.

22. There has been systematic reduction in price of cells. Pricing information can be of three categories: small quantity, mid-range and large quantity buyers.

23. Rooftop installations supply power directly to electricity user.
