Solar power is a good thing to consider if you use a lot of power and your roof gets a minimum of five hours direct daily sunlight. The money and energy saved by installing solar panels is well worth the energy invested into installing them.
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.

A charge controller is a great addition to any solar array, specifically those that are working above 10 watts on a regular basis. These small devices act as "ON" and "OFF" switches to protect your batteries. They prevent overcharging from damaging your batteries and can provide more advanced charging options depending on the make and model.
If you know nothing about installing the equipment needed for solar energy, contact a professional to do it for you. The installation of solar energy panels and equipment is something rather specialized. If you attempt to install it yourself and do not do it right, you can ruin the equipment involved.
