Mitsubishi Solar modules use polycrystalline technology, which means they are able to collect more of the sun’s rays. Mitsubishi panels are more environmentally friendly because they do not use any lead solder. Mitsubishi panels feature a universal junction box that allows for quick and easy installation. The panels are tested and certified internationally, including the United States, and qualify for federal and state incentive programs relating to the purchase and installation of solar energy products.
