Case study: Rogers Wells, Hay-on-Wye, Wales

Roger has a 300 watt solar panel and two 1,080 watt solar batteries

He’s already broken even on the system

The single-panel setup saves him at least £100 per year


We spoke with Roger Wells from Hay-on-Wye about his solar panel system.

Five years ago, Roger installed a solar panel and battery at his home near the Wales-England border, to take his shed and caravan off grid. Here’s what he told us about his experience.

Q: How long have you had your solar panel?

A: “Approximately five years.”

Q: Why did you decide to get a solar panel?

A: “I have an off-grid setup with a shed and a caravan, so I needed power for lights and the caravan’s water pump.”

Q: Are you pleased you bought solar panels?

A: “Yes.”

Q: How big is your solar panel system, and how much did it cost?

A: “I have one solar panel – it’s 1,200mm x 800mm, with a maximum power of 300 watts. It cost £150.”

Q: What was your experience like buying the panels?

A: “Easy – I bought it online, and it came with the complete kit: the panel, mountings, fixings, wiring, and a solar charge controller.”

Q: Do you have a solar battery?

A: “I have two 90 amp hour, 12 volt batteries.”

Q: Do your solar panels generate enough power to cover all your electricity needs?

A: “Yes for most days – I have a small portable 240 volt generator if I need it.”

Q: How much money do your solar panels save you on your electricity bills?

A: “It’s difficult to estimate, as I’m not at the site all year. It uses very little energy and I’m not connected to the grid, but it probably saves me about £100 per year on actual kilowatts of energy. I also save on the standing charge*.”

* The average household’s standing charge comes to £165 per year

Q: Have you managed to break even on your solar panels?

A: “Yes.”

Q: What’s your opinion of solar panels now?

A: “I have been very pleased with the solar panel, and would like to install more at some point.”

Q: Please can you describe your experience maintaining your solar panels?

A: “I clean it off a couple of times a year – otherwise, there’s no real maintenance.”

Q: Do you feel likely to buy other types of renewable technology?

A: “Yes – I would consider getting an electric car, but feel that the infrastructure would need to be better before investing.”

Q: Would you recommend solar panels to other homeowners in the UK?

A: “Yes – with careful costing, consideration, and self-installation, it can pay back and be a great investment.

“It’s a sustainable green energy source, and it’s great being independent from the grid.”

Q: Is there anything you wish you'd known before you bought solar panels?

A: “I would have liked more information on how to calculate the energy requirements of my home, so I could’ve better selected a solar system that I’d be sure would provide for all my needs.

“I would also have liked a comparison figure of solar panels and solar thermal panels in terms of energy produced per square metre.”
