Powerwall vs. Backup Generator

What is a Backup Generator

A backup generator is a device powered by fossil fuel such as liquid propane, diesel or gas to power your home during an outage. Depending on the size of the generator, it can provide power for your home while fuel supply lasts.

A backup generator is mostly installed outdoors, requiring additional construction work. It may require regular maintenance, as they are used infrequently, to ensure they are functional and have adequate fuel.

When paired with solar, Powerwall works daily to reduce your monthly electricity bill. Over ten years, these savings can make Powerwall and solar more cost effective than a generator.

Powerwall creates savings by storing excess solar energy to power your home. Powerwall, paired with or without solar, can be set to increase savings with Time-Based Control, using smart charging and discharging to maximize the economic value of your home energy system. 

In some regions, Powerwall can participate in Virtual Power Plants (VPP), a network of homes with solar and battery systems that work together as a single power plant. Stored energy in Powerwall may be used when the grid needs emergency support and through partnering programs, Powerwall can earn you money.
