Real solar installs from REST customers

Ben C · Barnet · July 2025

£405 a month on electricity, and a system built around the evenings

Before the install, the house in Barnet used about 18,000 kWh a year and the proposal put the bill at £4,860, around £405 a month. That is a lot of evening and overnight demand, so Ben's system pairs 12 panels with six Duracell batteries, 30 kWh of storage.

His proposal estimates £2,596 of benefit in the first year. REST rang him about a way to offset the cost of solar by buying less electricity, and he told us everything REST said it would do, it did.

“They did a really good job. It's a very, very neat job.”

Steve W · Kenilworth · July 2025

From a £1,172 yearly electricity bill to an estimated £1,186 first-year benefit

Steve's house in Kenilworth was put at about £1,172 a year on electricity in the proposal, on 2,537 kWh of use. His system has 14 panels, 7 kWp, and two Duracell batteries holding 10 kWh.

The proposal estimates £1,186 of benefit in the first year, counting both the electricity the system saves and what it exports. Steve recorded a short video about it afterwards.

“I'm well chuffed with the solar and the batteries and inverter.”

Ricky C · Bolsover · July 2025

An estimated £1,305 in the first year for a home in Bolsover

Ricky's home used about 5,032 kWh a year and spent around £1,507 on it. The system is 10 panels, 5 kWp, with two Duracell batteries, 10 kWh in total.

His proposal estimates a first-year benefit of £1,305, from the electricity the panels and batteries cover and the surplus that is exported. He recorded a short video once the work was finished.

Lance D · Ongar · August 2025

A 10 kWp system for a home using 8,500 kWh a year

Lance found REST through Facebook while he was looking at solar. He said the first meeting answered his questions and came up with a solution that worked for him, and that he chose Duracell batteries because it was a name he already knew.

The system has 20 panels, 10 kWp, with three Duracell batteries holding 15 kWh. The proposal puts the home's bill at about £2,099 a year and estimates £2,254 of benefit in the first year. He said four installers were on site all day.

“Really happy with it, really neat, cleaned up, no complaints.”

Michael C · Narberth · October 2022

A 2022 install that has kept working

Michael looked at several companies and had quotes from a few. REST was not the cheapest, he said, but it gave him the certifications and guarantees the others did not.

The install took a day, with the team working into the evening by torchlight, and the panels went on the other side of the house from the first plan to make better use of them. The system has 11 panels, 4.1 kWp, and the proposal estimated a first-year benefit of £708.

“The system's been working, touch wood, without any problems at all.”

Gursher S · Coventry · June 2025

A 6.5 kWp system and a 10 kWh battery in Coventry

His proposal estimates £774 of benefit in the first year. He recorded a short thank-you to the installation team.

“We are very thankful for all the service they provided.”
