SolarCity has recently created the world’s most efficient rooftop solar panel that includes a 22 per cent conversion efficiency. The sun-powered startup that was founded by Lyndon and Peter Rive (Elon Musk‘s cousins), SolarCity, announced their construction last week.

Adding a photovoltaic system to one’s home not only cuts down energy use, but also increases the resale value. According to Robert Madden of Green Leaf Realty, solar powered homes have a price premium of 30% over non-solar homes.
