Ask your solar panel vendor about the certifications they have and about the testing of the panels you are interested in. You might qualified for some rebates offered by the government if you go through a certified vendor and choose panels that have received certifications too. Besides, this is a good way to make sure you are getting a quality product.
When most people think about solar energy, they think that it has to cost a lot of money, but it doesn't. If you want to use solar energy, but you have a limited budget, you can install solar powered lights in your yard. This is a good way to save energy without spending more than you can afford.
If you are thinking about using solar power in your home, you must consider how much direct sunlight your home is actually exposed to. In order for solar energy to be worth it, your roof should have full sun exposure a minimum of 6 hours every day. You should also be wary of any areas of your roof covered by shade.
