Tesla Solar Roof
Now on its third iteration, it appears Tesla's Solar Roof is finally ready for widespread adoption. Far more discreet than a standard panel system, it's a complete roof replacement with tiles that double as solar panels while lasting up to three times longer than their traditional counterparts. While it can be used to augment traditional power sources, it can also be combined with Tesla's Powerwall batteries to form a completely off-the-grid system. As an added bonus, it's cheaper than a traditional roof replacement plus solar panels, so for new builds and remodels, it makes financial sense, as well.
