Solar Panel Installation Truro
Truro and the surrounding towns have a different building stock to Devon: more granite, more slate, different roof pitches. We've done plenty of installs across Cornwall and we know what works on Cornish properties.
Solar in Cornwall: What's Different Here
Mild year-round temperatures, slate roofs, exposed coastal sites, and a lot of protected landscape. Here's what that means for solar.
Cornwall's mild climate means little snow or frost on the panels, and panels work more efficiently in cool temperatures. We model the generation for your specific roof at survey.
Cornish roofs are most often slate. We use fixings designed for slate roofs that don't require drilling through the slate. They hook under the slate instead.
Most installs are permitted development but Cornwall has a lot of AONB, World Heritage mining sites, and conservation areas. We know which ones need applications and what Cornwall Council will accept.
Storms can knock out supply in exposed parts of Cornwall. A battery with backup keeps your heating and fridge running when the power goes out.
If you run a holiday let or B&B, solar cuts your overheads and guests increasingly expect it. We've installed on several Cornish holiday properties, where usage is high in summer when generation peaks.
All mounting systems use marine-grade stainless steel and aluminium as standard across the industry. Where it really matters for coastal properties is the battery and inverter. We specify the Anker SOLIX X1 for coastal installs, which is rated corrosion level 5 and IP67.

What Devon Customers Say
What our customers across the South West say, in their own words
“We recently had a solar panel system, EV charger and battery fitted by Yarmer renewables. Matt, Char and team were amazing and installed the system quickly and with great care (despite the horrendous weather). The quality of the installation has really impressed us, while the advice and information throughout the process has been excellent. We're loving our new system!”
“From multiple quotes and pitches from solar providers, Matt at Yarmer Renewables delivered something refreshingly rare: a system built from product knowledge and from listening to what we wanted. The installation went incredibly smoothly and was professionalism from start to finish. It was a pleasure to have them on site.”
“I've just completed the 'who do I get to fit the solar?' puzzle with the maze of choices and deals out there. Matt from Yarmer Renewables was an accidental contact but it has been a happy accident! Although I initially had some reservations about using a smaller installer I would now unreservedly recommend them. Everything has been well designed and is bespoke to this house.”
Cornwall Solar Installation FAQs
It depends on the size of the system, whether you add a battery, and the property itself. Difficult scaffolding access, listed building work, a three-phase supply, or roof repairs needed before install all affect the cost. We survey for free and give you a written quote, with the projected numbers for your specific property.
Usually yes, but it may need a planning application. The key is using all-black panels (no silver frames), low-profile mounting, and positioning that isn't visible from public roads. We've had installs approved in AONB areas by getting the aesthetics right.
The panels are sealed glass and aluminium, so salt doesn't affect them. All mounting systems across the industry use marine-grade stainless steel and aluminium as standard. The real differentiator for coastal properties is the battery and inverter choice. We specify the Anker SOLIX X1 for coastal installs, which is rated corrosion level 5 and IP67.
Not at all. Slate roofs just need a different fixing method: hooks that slide under the slates rather than drilling through. We've done loads of slate roofs across Cornwall. Takes slightly longer to install but works perfectly.
Cornwall winters are mild (panels like cool temperatures) and you still get decent generation October-March. For storms, the panels are rated for extreme wind loads and properly fixed.
It depends on system size, how much of the power you use yourself and your tariff, so we work it out for your property at survey.
