Solar Panels on the roof or ground mount generate power into a Grid-tied Inverter essentially turning the power company’s meter backward. These types of systems make a very compelling financial package, including power generated, state and federal tax credits and, in some localities, utility rebates the payback can be as quick as seven or eight years, but almost always less than ten years. These systems offer a fixed power bill immune to power rate increases, little to no maintenance, and last for decades. The downside of these systems is that they do not generate any power in the event of utility power failures.
