Detailed reviews
Every person I dealt with at Grayson solar installations was very knowledgeable and professional. We have had the panels and batteries for a year now and they are better than I thought they would be. The batteries they recommend are saving us lots of money it the winter as well as selling electric back to Octopus in the summer. Grayson solar installation offered bigger better batteries than any other company offered for less money. My setup works just as Connor said it would and cutting out the third party meant there is one number to call if we have any issues.
Solar panels were installed to a very high standard, really helpful service at the beginning with the planning and design to make certain we got exacting want we needed to best suit our needs. Their are a lot of solar installed with poor performance record but these guys are right up there with the very best. The work was carried out to a very high standard, communication from start to finish was excellent and the installation was completed in one (long) day. Very highly recommended.
This company did an excellent job. Gave us all the information we needed and any time we were not sure of the process, they were always happy to help. Can’t recommend them enough. Good value too, didn’t over charge like some companies.
