Many third-party companies offer PPAs that install photovoltaic systems at no upfront charge to the building owners. The company finances, installs, and maintainsthe system while charging the building owner for the electricity used over the life ofthe contract. Often this price will be equal to or lower than what the owner previously paid for power, resulting in a win-win situation. Financing makes photovoltaicsystems less risky and more accessible for residential or commercial sites. Thisremoves financial hurdles and maintenance responsibilities.
