Tesla unveiled its third-generation Tesla solar roof tile last year, and this year the company appears to be finally ready to go on sale. Elon Musk says solar roofs designed for new or replacement roofs are cheaper than new roofs and separate solar systems installed on roofs, which is true in about 80 percent of cases.
The latest third-generation Tesla solar roofhasing has a higher power density, which means that the required solar roof tiles are reduced by 50 percent, helping to reduce costs. Tesla estimates that the third-generation Tesla solar roof tile system, with a 25-year warranty, will still cost about $33,950.
In many ways, Tesla solar roofs are better suited to Europe, super-cheap asphalt roofs are rare, and slate-shaped black glass tiles are better suited to Europe. In the U.S., it remains to be seen whether Tesla installs its own solar roof tiles, as it does in Europe and elsewhere.
