You can depend on solar panels. They don't have moving pieces, so when you buy a system, you can rest assured that you will not have to fix anything or buy any new parts. It takes very little effort on your part to create enough energy to power your home, making these systems a very attractive option for most people.
Do not install a solar system in your home without first doing an energy audit. An energy audit will assess your energy needs and will help you utilize savings before installing a solar system. The last thing you want to do is install a solar system to pay for energy you are wasting.
