When you think of solar energy, you probably think of huge panels on the roof of your house. You have more options if there is some space on your property. If they are fitted with trackers that follow the sun, and special mounts, they can more efficiently capture the sun's rays throughout the day. Still, it will take a little bit of room.
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.
Don't assume that just because a company sells and installs solar panels means they are good and trustworthy people. Shop around. Get a minimum of three quotes. Read all contracts. Check backgrounds of potential contractors. Deal with this like any other home-improvement project that you would otherwise do.
