Pre-built solar homes could make renewable energy almost 50 percent cheaper

For many homeowners, the idea of finding an affordable solar company and retrofitting their homes with solar panels is too costly and time-consuming. What if homeowners could instead buy a solar-powered house straight off the production line?

These self-powered homes may be coming to a neighborhood near you in a not-so-distant future.
