Energy costs seem to be steadily on the rise. Concurrently, due to increasing marketing and decreasing installation costs, photovoltaic (PV) systems, or solar panels, are becoming more popular nationwide.
Depending on the neighborhood, one can easily see more homes of all sizes with roof-top solar panels. The benefits of solar panels are clear. Free energy from the sun, lower utility bills, and less dependence on public utility providers make solar panels hard to argue against.
