The questions we hear most
Are solar panels worth it in the UK?
For most homeowners, yes. Panels cut the electricity you buy from the grid, and you can be paid by your energy supplier for power you export. The saving depends on your usage, roof and tariff, which is why we survey first and quote honestly.
How do solar panels work?
Panels turn sunlight into direct current electricity. An inverter converts it to the alternating current your home uses. Anything you do not use can go into a battery or be exported to the grid.
Can solar panels be installed on a flat roof?
Yes. Flat roofs use mounting frames that tilt the panels towards the sun. It is a well-proven option, and our survey will show what fits.
What solar panels do I need?
It depends on how much power you use, how much roof you have, your budget and what you want to achieve. We assess your property and recommend a system to suit, with a clear quote.
Why are solar panels good?
They lower your electricity bills, use clean energy, give you more control over your supply and need little maintenance. They can also add to a property's appeal. Many people pair them with a battery so they use more of their own power.
Will solar panels save me money?
Generating your own power means buying less from the grid, and exporting the surplus can earn you payments from your supplier. Savings depend on usage, so we never promise a figure before a survey.
Will solar panels work in the winter?
Yes. Output is lower on short, dull days, but panels keep generating on overcast days. Angle, shade and local weather all play a part, and regular maintenance helps them perform.
Is the quote really free?
Yes. Every quote is free and no-obligation. We survey, explain your options and leave the decision with you.
Are you insured, and is the work guaranteed?
Yes. All our work is fully insured and backed by guarantees. Ask for the details when we quote.

What our customers found
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.
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.
