  Kierran was excellent from start to finish, ours was an unusual project with a ground mount system required. Kierran sourced an excellent “Cornish Rocker” mounting system and fitted top quality inverter and battery. He has also guided me through setting up the monitoring and has even contacted me recently to let me know the system had registered a fault due to local transformer issues that i was completely unaware of. Excellent customer service and so good to use a local company.

  Having acquired various quotes online from larger companies it soon became apparent that going with a local firm was the wisest way to go - given I live in Cornwall and access to my property is quite tricky. I was extremely thankful to have Kieran and Key Solar recommended to me . Knowledgeable, professional and reassuring from start to finish, Joe and Tiago did a great job installing the system and were a pleasure to have around the place. Highly recommended . Mark Polperro

  When we decided to install solar on the restaurant roof, we didn’t know a great deal about how it all worked. They explained everything step by step in a way that actually made sense to us, without overcomplicating it. We always felt comfortable asking questions, and nothing ever felt rushed. Key Solar was brilliant. The team were professional, turned up when they said they would, and kept everything running smoothly around our business. Since the installation, we have already seen a really positive impact on our electricity bills. Which as a restaurant makes a huge difference. Being able to see what we are generating through the monitoring platform has been one of my favourite parts. It is reassuring and quite exciting to watch it working, especially on a bright day. We are really pleased we made the decision, and now we just keep hoping for more sunshine

  Excellent experience start to finish. Keirran corrected, completed and improved an existing solar/battery installation put in by a different company. Considered our wishes throughout, he and Tiago very polite and respectful throughout. Clean and tidy, and system now working properly and better than ever thanks to Keirran. Also installed EV charger giving me access to extremely cheap off peak when sun isn’t shining! Highly recommend to anyone.

  Great quality service; from estimate, planning through prep work and final execution. Enjoyed the system for a year now so tried and tested. Also very professional and responsive handling of post sale and post execution queries. Highly recommended!

  Kieran and his team were great from the first contact during installation and proactive follow up communication. Really pleased with the performance from the panels and battery. I have recommended them to all my friends.

  A job well done. Many thanks to Ryan, Tiago and Kieran for an excellent service in replacing our solar panels and inverter. Extremely professional, polite, very tidy workers, keeping us informed at all stages of the process. The only hitch was a delay in the removal of the scaffolding upon completion but in view of the horrendously high winds and torrential rain we've had recently, it would not have been safe to do so earlier. I highly recommend them.

  Absolutely fantastic service, from pre-sales advice right through to installation and after sales. Key Solar have an honest, friendly, no nonsense approach and really go out of their way to offer the best product for your needs. The whole team are incredibly enthusiastic and eager to demystify all the techno jargon, presenting everything in laymans terms. The system was installed in just under 2 days and is peforming beyond expectation. The price was way better than the competition and to top all, they are local. If you're thinking of installing solar then these guys should be at the top of your list. If they keep up the good work, I believe that Key Solar are destined to become one of the major installers in Cornwall.

  Kierran Bond of Key Solar, Have installed a complete system on our new bungalow with battery back storage. I have found Kierran very helpful in explaining everything about the solar system and showing us how everything works as well as setting us up so we can monitor our system 24/7. First class service from Kierran and his team, would strongly recommend Key Solar Ltd.
