Solar power has been around for a long time, and over the years, the systems have gotten more efficient and more affordable. Once the system is installed, the energy delivered is completely free, and also completely emissions free. In the right areas, a properly designed and installed system can power an entire home, with energy to spare. If you are considering a photovoltaic system (AKA solar power), ask your contractor some questions before you sign on the dotted line.
