Make sure to have your solar panels professionally installed. The installation of these panels needs to be very precise, and you do not want to mess it up. Having a professional installation also provides you with a warranty, and this gives you somewhere to turn if things are not working right.
Be prepared to keep your solar panels clean. The dirtier they get, the less efficient they are at generating power. While it is true that rain and wind can often take care of a lot of this for you, you do need to get up there sometimes and dust them off yourself.
