Reviews

5.0

Preseli Solar Ltd customers repeatedly describe the team as friendly, polite and professional, with many praising the tidy installation work and clear explanations of how the system and app work. Reviewers mention solar panels, batteries, inverters and EV chargers fitted to a high standard, and several say the company found solutions for awkward roofs, old properties or shading that other installers had called unsuitable or not worth doing. One reviewer reports around 26% more energy harvested after optimisers were fitted on a shaded roof, and another reports a large drop in electricity bills. Ian is named in several reviews as helpful and responsive, and one reviewer says the firm returned to fit a battery years after an earlier installation. One reviewer noted complications with their property and a poor wifi signal, but said the installation otherwise went without drama.

Had solar panels fitted this week. Had previously had various surveys saying my property wasn't suitable, but Preseli Solar came up with a bespoke solution. We also had a battery installed. We're delighted with our new system, it's our first full day generating today and our battery is already charged, we are already pushing power back into the grid. The guys who did the fitting were great, all knowledgeable, very tidy and hard working, the panels also look really good. I would certainly recommend this company, great service and reasonable price.

⭐⭐⭐⭐⭐ Outstanding service, workmanship and system – highly recommended I cannot recommend Preseli Solar highly enough. From their first visit, they took the time to understand exactly what we wanted and proposed a complete solar, battery, gateway and LPG generator system. They also identified that, because of shading across our roof, individual panel optimisers would be important to get the best possible performance from the solar array. They were prompt in attending and providing a quotation and quickly obtained the necessary confirmation for our grid export. Installation was equally impressive. The standard of workmanship was excellent throughout, with everything installed neatly and professionally, including what was quite a complex electrical installation. The team completed the entire system with minimal disruption and no fuss whatsoever. They clearly took pride in their work and were extremely tidy — in fact, they left the areas they had been working in cleaner than they found them! Once everything was installed, they carried out a full test and demonstrated the complete system working, including the integration between the solar panels, battery, gateway and LPG generator. The results have already justified their advice. The post-installation monitoring app has shown just how important the optimisers were for our shaded roof — they have enabled us to harvest around 26% more energy from the solar array than we otherwise would have captured. What impressed me most is that Preseli Solar successfully did several things that other installers had told us were either impossible or not worth doing. They integrated our LPG backup generator with the battery system, successfully installed the roof fixings despite our difficult slate-effect roof tiles, where there was a real risk of tiles breaking, and used optimisers to maximise the performance of our partially shaded array. Rather than simply installing a standard system, Preseli Solar designed a solution around our property and our requirements, overcame several challenges that other installers had said couldn’t be done, and delivered it to an excellent standard of workmanship. Most importantly, the complete solar, battery, gateway and LPG generator system works together exactly as intended. Five stars without hesitation. I would absolutely recommend Preseli Solar to anyone considering solar, battery storage or a more complex integrated energy system.
