Baywa r.e to offer Tesla Powerwall for US solar installations

BayWa r.e. Solar Systems, the German company's US-based distribution arm, will begin distributing and storing Tesla Powerwall battery systems.

BayWa r.e. will add Tesla Powerwall in California and is already looking to expand availability to other US states in the near future.

Tesla Powerwall is a rechargeable battery energy storage system and therefore eliminates the need for consistent utility grid consumption by storing excess energy produced by a solar system and using it during periods of low production, such as at night or during power outages.

"The addition of Tesla Powerwall marks an exciting milestone in our commitment to advancing the future of energy," said David Dunlap, VP of product strategy at BayWa r.e. Solar Systems, LLC.

Dunlap added that by adding Powerwall, their solar installation partners "can unlock self-generation for American homeowners all while reducing their electric bill and carbon footprint."

With a 13.5 kilowatt-hour (kWh) energy capacity and a max load of 10 Powerwalls per system, homeowners can store up to 135kWh of energy right on their property and become their own clean energy power plant.

In April 2023, California approved the NEM 3.0 net metering policy update which will see solar systems earn around 75% less for the excess electricity they push back onto the grid. This will reduce overall savings and increase the payback period of home solar.

The policy, which has received a mixed response from industry, aims to encourage residents to pair solar and storage and become more self-sufficient, rather than employing a solar-only approach which encourages greater reliance on the grid.
