Solar PV modules produce electricity when bathed in sunlight; they have no moving parts and make no noise. TFS installs photovoltaic (solar) modules manufactured by SunPower and LG Solar. Both have excellent reputations for quality products, strong environmental records, and exemplary corporate governance histories. Both manufacturers have a linear power performance warranty. SunPower offers 95% of rated power for the first five years, and -0.4%/yr after that, with a full manufacturer’s warranty for 20 years, including all labor, testing, materials, etc. not just performance. LG offers a warranty on 97% of rated power for the first year and -0.7%/yr after that with a full manufacturer’s warranty for 10 years.
|Headquartered in Sunnyvale, CA, SunPower has the highest panel efficiency commercially available for residential applications. SunPower’s high-efficiency panels generate up to 50 percent more power per unit area than conventional solar panels, which makes them a great option when roof space is limited. These panels are uniquely attractive with an all-black appearance.|

Inverters are the brains of your system; they operate silently and interface seamlessly with the utility grid. Primarily, they turn the DC electricity from your solar panels into AC electricity, which is compatible with your household appliances and the utility grid.
At TFS we install SMA, Enphase, Fronius, and PVPowered grid-tie inverters. All of these manufacturers produce high quality equipment backed by 10-year warranties. The choice of which inverter to use in any given system rests primarily with matching the solar electric (PV) system size to the most appropriately sized inverter.
|SMA Sunny Boy grid-tied inverters are known for their reliability, modular expandability, high efficiency, and ease of operation. SMA inverter’s compact size and economical price make a nice option for various sizes of residential systems, and for adding a bit more power to an existing solar installation.|
