The recommended amount of solar panels for your home depends on its roof size. If you have a smaller roof, you may only need one or two panels, while a larger home may need three or four. As long as your Powerwall connects to a solar panel, it will charge and store energy.
Additionally, you can use a Tesla Powerwall without solar panels. If you’re still researching solar, you can install your Powerwall using regular electricity. The Powerwall will store energy for later use and help keep your costs low. For example, if you’re using a lot of power during peak hours, your Powerwall will supply the energy you need instead.
