What West Sussex properties need
West Sussex covers new-build estates, village cottages and a lot of rural land, with the South Downs running through it.
- New-build and modern estates. Straightforward roofs suit solar and a battery well. Many owners add an EV charger at the same time.
- South Downs and village homes. Some areas and listed buildings have extra rules. We check them before we quote.
- Rural properties and outbuildings. Large barns and farm roofs can carry bigger systems. We quote commercial and farm roofs too.
- Coastal homes. Worthing, Bognor and the coast face sea wind. We choose mounting to suit and offer health checks afterwards.

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