If you invest in a large solar energy system, you could actually make money off of it. If you can pull enough solar power with a collection of solar panels, you may be able to sell your excess electricity to neighbors or even the power company. Contact your local company to see if this could work for you.

Don't walk on solar panels unless you really need to. They cost a lot of money, and you don't want to inadvertently damage them. Do not walk on the ends, as they are the most unstable parts.
If solar panels are too expensive for you, think about renting them. Leasing is not as expensive as buying, and you can realize your savings sooner, like around a few weeks.
