The key takeaway from a Tesla Powerwall is the fact that it’s solar. This means you won’t have to worry about having enough fuel for your generator, and you also won’t have a lot of maintenance to keep up with. A Powerwall comes with a 10-year limited warranty, so you can rest easy knowing your investment is protected for a decade. This does help make the upfront cost much easier to swallow, but it’s still not going to be something that’s meant for everybody.
If you’re planning on getting a Powerwall to help cut back on your electric bill or lower your carbon footprint, it can be a great option. CNET ranked the Powerwall 2 the best overall solar battery in 2024, and it comes with a long laundry list of positives. However, since it’s strictly a backup power source, there are cheaper alternatives worth looking at. Tesla claims a Powerwall will be cheaper over 10 years provided you keep up on maintenance with a backup generator, but that certainly varies by person.
