The sun shoots off a massive amount of energy toward Earth every day. Instead of using solar energy to darken a tan, it’s time to harness those photons to heat homes, bake cookies and power entire neighborhoods. Discover the basics of solar power at www.solarpowerbeginner.com. The Web site offers an introduction on how to use it at home and the cost of photovoltaic systems. The site also will connect people to solar companies in the Sacramento area. If installing an entire sun-channeling system seems too intense, the site also has information about portable solar panels, because the sun is everywhere.
