Tesla CEO Elon Musk announced that active tiles would cost $42 per square foot and inert tiles were $11 per square foot. Bloomberg estimated that renovating a 2,000-square-foot home in New York with 40% coverage of active tiles and a battery to store the energy would cost approximately $50,000 (after federal tax credits), but it would generate $64,000 in energy over a 30-year period.
Not a bad deal, particularly if your home has good exposure to the sun. Musk’s vision is that your home will collect solar power through the roof tiles and the energy will be stored in a central battery. From that battery, you will be able to charge your electric car. All your energy needs will be covered in one handy spot – clean, efficient and easy.
