Solar Photovoltaics (PV) – also called solar electricity, this proven technology will enable you to make and use your own electricity, as well as sell the excess to your power company (grid-tie system), store it at your location for later use (battery backup system), or do both (hybrid system).
Solar Hot Water (SHW) – this technology uses the sun to make hot water for domestic use or for space heating. These systems are comprised of a collector (flat-plate or evacuated tube), a storage tank, and a heat exchanger. The collector is mounted on the roof, and the storage tank is located near your home hot water tank. The two are connected in such a way as to allow the pre-heated water from the sun to flow into your domestic hot water tank.
