The recent approval by Tesla shareholders of the company’s merger with SolarCity prompted CEO Elon Musk to state that the Tesla solar shingles will cost less – and be much more durable – than comparable high-end, terra-cotta and slate roofs. The savings come from improvement in weight, which should help reduce shipping costs.
“If Musk’s claims prove true, this could be a real turning point in the evolution of solar power,” Bloomberg gushed in a recent article. “The rooftop shingles he unveiled just a few weeks ago are something to behold.”
Musk, however, makes his claims during a time when terra cotta and slate roofs represent some of the most expensive materials on the market; they can cost as much as 20 times more than their less expensive asphalt counterparts. They are also much more fragile than the asphalt as well, according to Treehugger.com.
