What South West customers ask us for
From Georgian terraces in Bath to farms in Devon and holiday lets in Cornwall, South West projects vary a lot.
- Farms, barns and rural land. Large roofs suit larger arrays. Ask us about commercial and agricultural installs.
- Period and listed buildings. Bath, Exeter and many villages have strict rules. We flag them early so you know what is possible.
- Holiday lets and second homes. A battery and good monitoring help where usage swings between busy and empty weeks.
- Off-grid and remote homes. Remote addresses need more planning. Call us to talk through what is realistic for your site.
Tell us what your roof looks like and we will say what the South West homes like yours usually fit.

What customers say about SW3
Real reviews from homeowners we have installed for.
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.
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.
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.
