A common misconception about solar panels is that they require a lot of maintenance and that could not be further from the truth. Solar systems require very little maintenance because they are built to withstand hail and other harsh weather conditions and they have no moving parts. Occasionally, solar panels will need to be cleaned if you live in an area with that has a lot of smog, dust or other debris, but this is very easy and inexpensive to have done! If you leave the dust to accumulate over a long amount of time, it can bring down your electricity production. That is why it is best to clean your panels every once-in-awhile!
