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 only want to go partially solar, look at small-scale applications for this energy source. There are two ways to do this. First, find solar panels you can mount on or at windows to recharge portable electronics. The other way is to buy camping tools like lanterns and cooking equipment that is solar powered. Every small thing that you do saves you a little money and helps the environment.
