We are currently offering FREE Solar Panel Roofing System estimates so that you can cut your current energy bills by up to 50%. Today there are numerous popular solar technologies available, and although the field of photovoltaics is constantly evolving, the most common and reliable today are photovoltaic solar panels. These solar energy panels convert sunlight into energy via cells of silicon crystal and other materials that will give off an electric spark when struck with sunlight. These panels are generally installed on the roof of your home and convert sunlight into direct current (DC) power. Then, the DC power flows to an inverter. The inverter converts the DC power to alternating current or AC power. This is the type of power that is standard in most homes and commercial properties.
