The US EPA research facility in Raleigh, NC uses our solar street lights on the entrance road leading into the facility. The original installation cost for utility extension and materials was over 2 million, and then enduring monthly utility charges. An alternate solution of solar lighting was provided at the total cost of 850 thousand with minimal maintenance and zero utility cost. The project was installed in 2001 and has since had one round of battery and two rounds of lamp replacements. The entrance sign is also illuminated using solar power.
