Photovoltaic systems, often referred to as solar electric systems, have never been more cost-effective to install, thanks in large part to efficiency enhancements that allow for more flexible placement and U.S. government tax incentives. Lower solar energy costs have removed the barrier that has traditionally prevented enterprises, institutions and municipalities from investing in one of the most environmentally friendly and non-disruptive energy technologies available.

For select projects, Ameresco eliminates the budget obstacles and political complications that prevent organizations from incorporating solar power into their energy supply by financing photovoltaic systems with no up-front capital cost and, if needed, by owning, operating and maintaining the project with a portion of the customer’s energy efficiency savings as payment. Whether it is a large solar array that provides a significant amount of a facility’s electricity and supplies energy back to the grid, or a few solar panels installed in a remote location to power critical equipment or supplement other power generation, we can objectively analyze each building and property to determine the best course of action based on budget and energy needs.
