JA Solar Panels Cornwall.
JA Solar panels use half-cut cell technology to cut internal resistance losses, giving strong output-per-pound without the premium price tag of some rivals. We fit them as part of a fully surveyed, MCS certified installation, designed around your roof's actual shape and shading rather than a standard template.
Consistent performance, proven track record.
DeepBlue TOPCon Cells
JA Solar is one of the longest-established Tier 1 panel manufacturers, and their DeepBlue range is built around n-type TOPCon cell technology, a step up from standard PERC cells that reduces power loss over the panel's lifetime and pushes efficiency to around 22.3%. In practice, that means your system keeps generating closer to its original output for longer, rather than degrading faster in the early years the way older panel technologies can.
Bifacial Panel Options
JA Solar also offers bifacial panel options, which capture reflected and diffused light on the rear of the panel as well as direct sunlight on the front. On the right roof, particularly lighter-coloured surfaces, flat commercial roofs or ground-mounted arrays, this can add a genuine yield boost with no extra roof space needed, which suits some of the outbuildings and larger commercial sites we work on across Cornwall.
Proven Track Record
What sets JA Solar apart isn't a single standout feature so much as consistency: strong efficiency, a solid 25-year product warranty and 30-year performance warranty, and a manufacturing track record stretching back further than most competitors, which matters when you're relying on a warranty being honoured decades from now.
Fully Certified Installation
JA Solar is a Tier 1 bankable manufacturer, meaning banks and lenders recognise it as a safe long-term bet, useful if you're financing your install or plan to sell the property down the line. Get in touch for a free quote and we'll talk through whether JA Solar is the right fit for your roof.

I cannot recommend Holloway Electrical highly enough. From the planning of our solar and battery installations through to the final commissioning Jamie's took care of everything. Organised other trades to assist, explained everything that was going on and completed the job on time as promised to an exceptional standard, I could not be happier.
We experienced a very friendly and helpful service from Jamie with our new kitchen electrics. We would highly recommend his services.
We are so pleased with the work that Jamie completed for us today, supplying power to our apartment garage and installing sockets and EV charger. The quality of the work is outstanding. I highly recommend Holloway Electrical Ltd, definitely our electrical professional for all future requirements!
Hi Jamie, Kieran did a great job and we are both very pleased with it. Thank you very much. I would like to discuss with you the electrical box in the kitchen which will need to be replaced. PEH
A lovely local company to deal with. Efficient and left everything clean and tidy. Highly recommend.
Great communication, excellent service, great price, 100% recommend.
We had several quotes from Electricians to install our EV charger which varied dramatically. Jamie’s quote was by far the most reasonable and he was the only one who bothered to come to our home and look at the charger etc. before taking on the job. He arrived on the agreed date of installation and was personable, efficient and tidy. I would have no hesitation in recommending Jamie and would be happy to call on his services again in the future.
