Solar energy is nowadays the most viable form of alternative energy. This is because solar panels have become more efficient than ever before. They can generate more electrical energy per square inch than ever before. Even with low intensity sunlight, most solar panels can produce the rated output. Battery technology has also come a long way. Modern batteries can store enough energy to power a home or streetlight until morning.
Viability of solar energy is not usually a topic of discussion nowadays. However, it is important to state that if you have access to the grid and your energy consumption is low, it may not make financial sense to invest in solar. This is because the grid can meet all your energy needs cost effectively. It is recommended you spend a bit of time searching for the best installer of solar panels to ensure you are able to make informed decisions.
