While there's not a single answer to such a complex problem, solar power has the potential to make a massive difference to those living in poverty. 

The vast majority of solar panels are made of materials that convert primarily visible light. But there are solar panels made of different materials that work best with other parts of the electromagnetic spectrum—e.g. ultraviolet or infrared light rather than visible light. 

California is pushing solar panels on every roof--and solar panels are often an eyesore. Fortunately, there are ways to make solar installations less hideous. And when done well, homes with solar sell about 20% faster than homes without, and add an average of $18,000 to a home’s value.
