TESLA SOLAR ROOF: HOW TO BUY AND INSTALL ELON MUSK'S ENERGY TILES

Tesla's third-generation Solar Roof, sometimes known as the Solarglass Roof, has arrived. Elon Musk's latest solar energy tiles, unveiled in October 2019, offer a striking design that promises to look like a regular roof to the untrained eye. The tiles have a lot to offer. They're designed to blend into a roof, while providing renewable power round-the-clock when paired with a Powerwall battery. They have a warranty of 25 years. Tesla has produced a video of them surviving the highest-rating hail, a two-inch hailstone moving at 100 mph. Traditional roof tiles fare less well. Looking at the figures, the roof also seems to undercut the cost of buying a roof and panels separately. Tesla claims a 10-kilowatt roof in California will cost around $33,950, equating to $5.60 per square foot or $2.11 per watt. That, Tesla claims, is cheaper than spending $54,647 on a premium roof ($34,091 at $11.92 per square foot) and retrofit solar panels ($20,556 at $2.05 per watt).
