Customers with Powerwalls say
Real reviews from homeowners we have worked with.
A big thank you to Chris, Paul, and the whole team at SW3 Green Energy Services Ltd! A couple of months ago, I had a 15-panel solar system installed, complete with microinverters and a Powerwall battery. I'm already seeing real savings, especially with being able to make the most of off-peak rates and getting good returns from my energy provider's export rates.
What really impressed me about SW3 Green Energy was their reliability and professionalism. They were on top of everything from the first quote to the final paperwork. My setup was a little complex, with specific requirements around the placement of the Gateway and Powerwall, plus integration with my Zappi EV charger. They handled it all seamlessly.
Even when my energy provider botched the smart meter installation, leaving my system down, Chris came back to sort things out and got it up and running again.
Stellar experience from start to finish. Chris, Paul, Sherri and anybody on their team has been extremely competent and nice to deal with. They inspected my property, provided a detailed survey suggesting a sensible setup, with good explanations about how it would all work together and they provided a very reasonable quote, with highest quality materials. By the end of the day they were able to get all my apps set up and properly configured with the energy provider.
We were quoted for 14 panels and 2 batteries and an installation date was set for 2 months later. Everything was delivered on time and the team arrived when agreed. The work was carried out by one electrician who was excellent. It was a very neat installation and done in a day and a half. Any queries were dealt with promptly and to our satisfaction. We would recommend the company.
