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.
Solar cells can cost more than other alternatives. Get a professional to perform an energy audit on your home. This can help you find the ways you waste energy so you can change them. By making these changes, you may not need to install as many panels.
