The Tesla Powerwall (energy storage system) is getting more and more interest from Midwest, where consumers would also like to store solar surplus electricity, and have backup power.
As a case in point, St. Paul-based All Energy Solar, one of the first in the country offer Tesla Powerwall installations, has all the business it can handle.
Why? The reason is fairly straight-forward:
“When the sun goes down, our house is still using energy generated from our solar panels. It is a good feeling knowing the energy is clean energy," said Ross Starfeldt, a homeowner in Bloomington.
A dozen or so Tesla storage systems have already been installed in the Twin Cities, but All Energy has another 50 customers waiting patiently for their turn next.
Brian Allen, co-founder of All Energy Solar explains that the costs of battery energy storage decreased enough to spark interest.
“Energy storage has been top of mind for a lot of solar energy customers, but cost has always been a driving factor. We’re now to the point where energy storage makes a lot more sense.”
"Allen started having conversations with Tesla about Powerwall two years ago, he said. The company submitted an application to become a certified installer and the company went through a “full-on vetting,” Allen said. Last year, he and a master electrician were allowed to attend an out-of-state training session at Tesla. All Energy began installing Powerwall batteries just two months ago."
