Lower your running costs
Energy costs hit businesses hard, and customers increasingly prefer firms that care about their footprint. Solar tackles both.
With over two decades of experience, we design systems for businesses across London and the South East, including Croydon and Redhill. The savings are yours to reinvest and grow.
- Best for daytime users. Offices, warehouses and farms use the power as it is made.
- A hedge against price rises. Make part of your own power instead of buying it all in.
- Little upkeep. A five-yearly service and the odd clean keep it running.
- Free, no-obligation survey. You know the numbers before you commit.

What our customers say
Real reviews from homes we've fitted.
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.
Very professional from start to finish. Excellent communication, installation of solar panels, battery charger and other equipment was on time and Constantine, the engineer, worked tirelessly with a minimum of fuss and bother. Follow up has also been excellent. Thank you.
