![]() But we don't yet know how that will play out in real-world settings. Musk said the shingles will last longer than the house and can produce nearly as much electricity as conventional panels. So while it was big on promises – a solar roof that costs less than a traditional roof plus electricity, combined with a bigger battery that also won't break the bank – it was short on critical details. Now, the (big) caveatsīefore you get too excited, remember that this was an Elon Musk unveiling. Even using batteries for part of a home's power needs could take stress off the system and minimize the arguments utilities are making about solar's impact on the grid. It's a fight that has polarized and politicized the Arizona Corporation Commission - and one that will play a central role in the rate hike and demand-based pricing plan APS is asking commissioners to approve next year.Īrguably, if solar users are able to store enough power to sustain them, there's no need to use the grid. ![]() This could solve the bitter battle between rooftop-solar companies and utilities, which argue that rooftop-solar users should pay to access the power grid at night or on cloudy days. Musk said during the unveil that the Powerwall could sustain a small house for a day by itself or indefinitely when combined with the solar roof. But this one is cheaper and stores far more electricity generated by solar panels, making it easier to power a house (or recharge an electric car) when the sun isn't shining. That leads us to Tesla's second new product: The Powerwall 2. ![]() Hey, a bonus! Problem-solver 2: The power wall And that could result in more panels being situated on the west side of homes, where they can better catch the late-afternoon sun and produce more electricity than south-facing panels.īetter efficiency. If you can't tell a solar roof from a conventional tile one, even "reasonable" restrictions become moot. That could solve long-standing battles between residents and homeowners associations over where to put the panels. HOAs can't ban solar panels on roofs, according to Arizona law, but they can enact "reasonable" restrictions as long as the rules don't "adversely affect" cost or functionality. They actually look like clay tiles, not the shiny black-and-blue glass boxes that hulk over our tile roofs today. ![]() Musk used homes on a Hollywood set to unveil his solar roof, and not even observant reporters could find the panels until he pointed them out. Tesla Motors CEO Elon Musk unveiled two products last week that could solve Arizona's problems with solar. Watch Video: Tesla doesn't want you to find The solar panels in this picture ![]()
