What comes to mind when thinking about solar energy? Most people conjure images of panels on a roof and not much else. They also seem to believe that adding panels is expensive and impractical. That is not the case.
Is it possible for solar panels to power a home? It turns out just one solar panel can run your tv! Assuming you use it for five hours a day and at an annual need of 400-500 kW/h, a single panel will be more than enough. Two panels can provide enough energy to power the fridge. Again, this assumes individual averages because each home uses energy differently. It is clear that the efficiency of solar panels is improving at a rapid pace, and the return on investment is reached in a relatively short period.

The average home uses about 11,000 kW/h each year, which would require roughly 22 panels. It can’t be stressed enough that a significant number of factors can push these numbers around, including how much energy can be sold to the grid during times when the system of panels is collecting more power than the building is using.
Regardless of its place in business or political discussions, the rapidly increasing efficiency of solar panel technology and the consequences of other energy sources are making solar energy more and more of a no brainer.
