If after installing solar panels you find that you are producing more energy than you need, you can sell the extra energy that you produce back to the electric company. This method will help you recoup the cost of your solar energy system's installation and parts. Additionally, after you have recovered your costs, you will be making a profit.
If you are considering installing a solar panel system, it is important that the panel faces in the sun's direction. Although this seems obvious, you would be surprised how many people forget this step. If your panel does not have sun, it won't power up. If you live in the Northern hemisphere, your panel should face South towards the horizon.

Check that your solar-energy installer has the proper licenses and insurance. Installing solar panels on a steep roof is a delicate job, and you should feel confident that your installers know what they are doing. At a minimum, look for a contracting license, workers compensation insurance, and general liability insurance.
It's better to get a solar system when you own a home. Don't overextend! If you have a mortgage and you need to finance your solar energy system, you could endanger your financial security.
