Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). While most people are captivated by the high-tech nature of solar-electric (photovoltaic; PV) systems, in most cases, a solar hot water system will harvest more energy at a substantially lower cost. In fact, compared to PVs, solar hot water collectors are more than three times as efficient at producing energy from the sun. Investing in a solar hot water system is a smart solar solution for most homeowners or company owners. This proven and reliable technology offers long-term performance with low maintenance. And with federal, state, and utility incentives available, these systems offer a quick payback in some cases, only two to four years. A thoughtfully designed solar hot water system could provide all, or at least a significant amount, of your household hot water needs for some portion of the year.
