Before installing solar panels on your roof, check with your home owners association. Some associations have restrictions on what you are allowed to do to the outside of the property, and this might mean solar panels are not an option for you. It is better to have this information up front than to purchase the panels and be forced to remove them at a later time.
Carefully consider the types of solar panels you plan on having installed. Long ago, if you didn't have enough roof space, you'd need very expensive high efficiency mono-crystalline panels. There are now more advanced polycrystalline panels and even thin film panels. If you've got enough roof space, you might wish to look at the size of the panels in relation to their output capacity to avoid having insufficient panels that you need more of later.

If you are looking for a solar energy system, make sure to ask your friends and neighbors about their experiences with various companies. A recommendation, or a warning, that you are familiar with can help you to make a smart buying decision. Your friends can also let you know about their experiences after installation, including any warranty issues and cost savings the system has offered.
