Installing solar panels is a complicated process. Some homeowners try to install the panels themselves to save money. In most areas of East Tennessee, the local power company may disconnect power to homes with self-installed systems and the manufacturer warranties are voided unless installed by a certified installer.

As sunlight is converted into electricity by solar panels, any extra energy generated is stored in these batteries for future use. Batteries offset energy usage when the sun is down but also provide backup power when the grid is down.

If you own an EV, or you’re in the process of shopping for one, you’ve probably considered solar panels as a way of lowering your electricity expenses and using fewer fossil fuels. What could be better than charging your futuristic vehicle with the power of the sun?

Supplementing an HVAC system with solar makes perfect sense. In addition to cooling a small area, it allows you to add capacity and reduce the load on an existing system.

Solar panel arrays can be cleaned using our telescopic, pure water fed, pole system. Deionized pure water cleans spot-free with no harsh chemicals that are bad for the environment and could damage panels voiding your warranty.
