I have had my Aztec Renewable Energy solar panels for over two years, and I am very pleased with the performance of the equipment as well as the whole process. Upon activation of my system, my average monthly electric bill went from over $150 to under $15. Additionally, it has required no service or maintenance. The initial sales call was low pressure, and Charles took the time to educate us regarding the use of solar energy. The cost of the installation was exactly what was quoted; and the installers were professional, experienced, and very proficient. The system is functioning just as efficient as it did on day one. I would recommend solar panels to save money and do good for the environment. I recommend Aztec because of their expertise and courtesy.
