Customers with batteries say
Real reviews from homeowners we have worked with.
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.
I'd highly recommend using SW3 for my new solar panels and battery purchase and install. The entire process was so smooth, from initial booking to the quick installation on the day. Thank you.
Excellent service from initial enquiry through to completion. Paul and Chris run a great team and are hands on to ensure everything runs smoothly. Installation was carried out in just one day and we were briefed thoroughly about the system before they left. Wouldn't hesitate to recommend SW3 and so happy we found them.
