TFS is proud to work with a number of local and national organizations, both for- and non-profits dedicated to making our community a better and more sustainable place.
We partner with nonprofits, industry associations, and other organizations that support solar as a meaningful energy resource. These associations include:
Amicus was founded in the fall of 2011 when a small group of friendly solar installation companies decided it was time to form a special organization where independent businesses could support each other by sharing best practices and pooling their buying power. Amicus is a purchasing cooperative that is jointly owned and democratically managed by its member companies.
Certified B Corporations are committed to higher standards of social and environmental performance, transparency and accountability. By joining the B Corp community and going through the certification process, TFS is able to support and help grow a movement we believe in.

Solar Electric Systems
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.
LG Solar, a division of LG Electronics with headquarters and manufacturing plants in South Korea, began producing solar modules in 2010 following 20 years of research and product development. LG Solar’s MonoX modules meet TFS’s high standards for great efficiency, long-term reliability, and rated energy output.
Kyocera Solar, Inc.

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.
Enphase Energy has introduced the solar industry’s first microinverter system. These inverters make it so that shading has less of an impact on system production. An Enphase microinverter attaches to each PV module, which allows us to monitor each module independently.
Fronius, an Austrian company has its USA headquarters in Brighton, MI. The inverters they manufacture are very versatile, reliable and efficient. Fronius inverters work with all solar panels commonly available on the market, providing maximum compatibility and flexibility.
Solar Hot Water SystemS
Flat plate collectors are the simplest and most common type of collector designed to provide 30 years of dependable service and backed by a 10-year manufacturer warranty. They come in various sizes (e.g. 4’X8’, 4’X10’), are thin (e.g. 3-4 inches), black to absorb heat, and covered with glass to prevent the heat from escaping. Collectors consist of copper tubes that use either distilled water or a glycol mixture as a heat transfer fluid. This fluid is pumped into the collector’s pipes where it is heated by the sun and then moved out of the collector.
Solar Water Tank
A solar water tank is an insulated water storage tank where cold water enters and solar heated water exits. Cold water enters the solar tank, and is heated by a coil of pipe containing the heat transfer fluid (e.g. distilled water or a glycol mixture) that circulates through the collectors. After the heat has been transferred, the heat transfer fluid is then pumped back up to the collector to start the process again.
AET (Alternate Energy Technologies) manufactures low-maintenance solar thermal flat plate collectors for residential and commercial applications. Recognized for their high performance, structural integrity and patented mounting systems, the AET collectors have been specified by utility companies as well as local, state, and federal government agencies. AET solar collectors are designed to meet or exceed most state and federal codes. Visit the
