Solar panels are a system of energy supply that takes advantage of the energy provided by the sun. As such, it is in principle an eternal energy source that will be viable as long as the sun exists. Truth be told, it is difficult to imagine another kind of energy that is not only as powerful but also as renewable as solar energy.
Keeping the world clean
Solar panels are also often compared to wind energy systems. Granted, both are extremely clean sources of energy, but Solar definitely has some advantages over wind. For starters, wind turbines can be extremely noisy, while solar panels are completely silent.
Moreover, whereas both solar and wind energy systems can be applied on a very large scale (Denmark generates forty percent of its energy from wind and all industrialized nations receive a significant amount of their energy from grids of solar panels). However, the biggest advantage that a solar panel has over a wind turbine it is scalable, and can be applied on an industrial, commercial, and even residential level.
This is because the technology behind solar panels is actually quite simple. Solar panels are comprised of pholtovoltaic cells (that are usually made out of silicon) which give off electrons when they interact with photons (light particles) thus creating an electrical current. Solar roof panels are easy to install, and are inexpensive when you consider the amount you are able to save on energy bills.
