Benefits of a Solar Energy System Solar energy systems do not produce air pollutants or carbon-dioxide. The flexibility of the modular PV system allows designers to create solar power systems that can meet a wide variety of electrical needs, no matter how large or small. Solar energy systems can be built quickly and in many sizes. They are well-suited to many areas. Because renewable energy generation can be owned by the end user, switching to renewable energy would put more power and ultimately more money in the hands of the general public, instead of into the pockets of energy companies. Home photovoltaic systems generally have no moving parts, are modular, easily expandable and even transportable in some cases. Most PV systems are installed on existing structures such as homes and commercial buildings and require no additional land. Many states offer rebates for solar projects. 31 states offer loans for solar projects. 21 states offer tax credits and sales tax incentives for solar projects. 30 states offer property tax incentives for solar projects. Many individual solar cells can be packaged together into pv modules which can then be placed on a rooftop, carport roof, in stand-alone arrays, and many other convenient places. Solar energy is the cleanest, most abundant, renewable energy source available. Once installed, a PV system produces no pollution and the energy is free. Renewable energy sources regenerate and can be sustained indefinitely. Reduce your power bill with this fun DIY project! Earth4Energy. Off Grid Energies Home
