What Surrey homes ask us for

Surrey has a lot of detached houses, big south-facing roofs and period properties. That shapes the systems we recommend.

  • Larger detached homes. Plenty of roof space means bigger arrays, and a battery to use more of what you generate.
  • Period and conservation-area properties. Some areas have extra rules. We check with you up front so there are no surprises.
  • Scaffold and access. Long driveways and mature trees are common. We survey for shading and plan access before we quote.
  • Home batteries and backup. We fit Tesla Powerwall, SigEnergy and more. Ask which suits how you use power.

What customers say about SW3

Real reviews from homeowners we have installed for.

Fantastic local company. I had 10 panels and batteries installed. Paul was great who explained to me the two different types of installs, he really educated us into the solar Pv world where other companies we dealt with did not. The install was neat and tidy, the installers where polite and friendly and Chris spent the time to set up the app on my phone which shows me all the features of the system. The lady I spoke with in the office, Sherri, was fantastic and very helpful in answering all of my questions. Pleasant experience all round.

H Johnston10 panels and batteries

Great experience with this family run company and a very fast and efficient install, from sales to installation was less than 1 month. We had 16 panels and a 10kw battery installed. Chris and Ben were great at making sure everything was fitted perfectly. Scaffolding was also put up the day before and then collected within 48hrs after work completed. Thanks so much would highly recommend!

Checkatrade reviewSolar installation, KT20

A truly excellent service from initial enquiry through planning, supply of equipment and installation. The electrician Dan’s workmanship was very neat and to a very high standard. I have no reservation in recommending Paul and his team for any solar, storage battery or other renewable electrical work.

Checkatrade review9.5kW GivEnergy battery, 3kW AC inverter, KT20

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.

Solar in Surrey: quick answers

Is Surrey your main patch?

Yes. Our office is in Walton-on-Thames, so Surrey is the area we know best and can reach quickest.

Do trees near my house stop solar working?

Shade reduces output, so we check it during the survey. Micro-inverters such as Enphase help when part of a roof is shaded.

Can you add a battery to solar I already have?

Often, yes. Call us on 0204 538 1967 with the make of your system and we will say what is possible.
