Tesla Powerwall - the rechargeable solar battery

Southwest Renewables are proud to be a Tesla Powerwall Certified Installer.

Power your home and electric vehicle with the renewable energy you generate and reduce your reliance on the grid.

With solar, you typically generate more clean energy than you use, especially if you’re out during the day. This means you end up exporting the energy you generate back to the grid at roughly 1/3 of the rate that you pay to import it.

Why not make the most of your solar system and store that extra energy? With the Tesla Powerwall, you can store the excess energy from your solar panels for use anytime – even during a power outage.

Monitor what energy you produce and control your self-powered system using the Tesla app.
