During the day, solar panels convert sunlight into electricity. This happens due to light photons striking a solar cell and knocking electrons free from the silicon atoms of the crystal structure of the cell.
The power generated from the solar is fed through our charge / load controller and charges the battery.
The solar panel acts as a photocell turning the light on at night. The charge / load controller controls the discharge of the battery powering the light fixture to provide accurate lighting operation.
The solar panel will sense when it is daylight again and will tell the charge / load controller to turn the light back off in the morning and go back to charging mode.
The solar modules come in a variety of Wattages and can be put together to create even more power. Depending on the needs of the device or devices and the geographic location of the installation determines the needed amount of solar power. For example one light in Texas may use an 85 Watt panel, but the same light would need a larger panel or panels in Michigan. Making sure that the correct Wattage necessary for the application is critical when determining the solar panel used.
