The first benefit of having solar energy is that you're not going to have to deal with an energy bill that is as high as it currently is.
With a solar powered home you just draw energy from wherever the solar panels are. You can then store that power in batteries for when it gets dark or cloudy. The only thing you have to realize is that this won't be enough energy probably for your whole home to run on constantly. You have to make sure that you're still on the grid unless you're willing to live with a lot of things being off all the time.
You have to get someone to install your solar panels that will do a good job. Since this is costly, it's not a good idea for you to hire someone that's not well known for what they do. Get online and find the solar power company of your choice's website. From there you can see if they look like they know what they're doing. After seeing whether or not their website is professional enough, you can then look to see if they are registered with the Better Business Bureau and what their grade is.
