Solar Hot Water

First Light Solar will design and size your solar hot water system based on the amount of hot water that you use. No matter what your needs, First Light can install a solar hot water system that will substantially reduce your energy costs.

To achieve maximum efficiency, solar collector panels containing a heat transfer fluid are installed on the roof at a favorable angle to the sun. Pipes lead from the panels to the hot water tank, where the heat is transferred to provide tremendous amounts of hot water. Even in winter, hot water temperatures can reach 180º.

Solar hot water systems are usually designed to provide 80% of the home’s overall hot water needs over the course of a year. In fact, for systems being operated on a continuous basis, if financed at market rates, the system earns money from day one—that is, the cost savings per month exceeds the monthly loan payment. Depending on the size of the system, it can pay for itself entirely in just a few years.

Solar hot water is among the most cost-effective means of supplying energy to a business or home. It is less expensive than grid-based sources of electricity including coal, nuclear, and natural gas. Solar hot water use has doubled in the United States over the last ten years, and it could provide 15% of residential domestic hot water demand by 2015.
