There are many establishments around the world that have installed solar power systems either on the roof or ground. In fact, most of these establishments are producing enough energy during the day to meet all the energy costs. Some have even surpassed their peak demand during the day and are now selling the extra energy generated to the grid. In addition to lowering their reliance on the grid, these firms are also making money by selling electrical energy to the grid.

Nowadays, there are leightweight solar panels which are just as efficient as older panels, but weigh much less. The weight of solar panels is a key factor of consideration because heavy panels can damage the roof of a building. When designing a solar power system for a building, the designer must consider the maximum weight the structure can accommodate, the lighter the weight of the panels the better.
