Get the records from your energy company on how much energy you have used in the last five years. You can then use this information to figure out exactly how much power you will need solar energy to provide for you home. Having the past five years is important so that you can see that some years you will need more energy than others.
Get your financial figures right before deciding on a solar system. You need to weigh the cost of the system against how much energy it will save you. Take the cost of the system and multiply it by its' lifespan. Now figure out how much energy you will use in that lifespan to determine if it is right for you.

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.
Once you have solar energy panels installed on your home, make sure that you keep them clean. Many people do not realize a cleaner panel will attract more of the sun's energy. Depending on the area you live in, you should wash your panels every two to four weeks or so.
