Sussex Solar advised and installed a Tesla Powerwall, Gateway and solar array. They were very efficient from the first contact to the final handover. Calls were always answered promptly and all questions dealt with very knowledgeably. The installation team turned up when they said they would and got on with the job and completed it in two days. The quality of the work was excellent and Sam was always keen to make the installation as neat as possible. Andy came to complete the handover and we are very pleased with the result. It was a pleasure to do business with a true family business. Andy, his son, Dom and nephew Sam. I would recommend Sussex Solar to anyone thinking about solar panels.

We wanted to add a battery to our existing solar and we were also considering increasing the solar array. We had 3 companies to give us quotes for the different possibilities. Sussex Solar stood out as being the most experienced and made most sense when explaining the best options for us. Andy, the director, was very friendly and knowledgable. He spent quite a long time with us, listened carefully to our needs and our current energy usage patterns. He explained all the different hardware options in detail. We felt confident that Sussex Solar were the ones for us. We never felt pressurised to choose at any point in the process. We chose a battery stack and inverter from Anker plus a new EV charger, as our was 13 years old and quite basic. Once we had accepted the quote, they kept in touch and before the work commenced, they found that Anker had brought out a new EV charger that would be better than the one we had chosen. This was suggested at no extra charge. The work took two days and the electricians who carried out the instalment were a pleasure to have on the property - they were quiet and polite, got on with the work with no fuss and explained everything fully. Since the instalment, Andy has visited to make sure everything is working as it should and to answer any questions. We are delighted with the work and have absolutely no hesitation in recommending Sussex Solar for any renewable energy project.

We saw Sussex Solar listed as a Premium Installer on the Tesla website and they definitely lived up to the Premium label. From the initial contact and Tom's site visit where we worked out how and where to install the battery and the gateway as unobtrusively as possible, through Jake and Sam's amazingly tidy installation to the post-installation director's visit from Andy everything was handled efficiently and professionally. Charlotte and Cherelle in the office kept us informed on dates and progress and answered our few questions promptly and politely. The installation was on time and on budget and we've no hesitation in confirming that Sussex Solar definitely are a Premium Installer.

I recently had solar panels installed by Sussex Solar Ltd and the entire experience was exemplary from start to finish. The process — from obtaining the initial quote through to final sign off — was faultless. Communication was consistently clear, timely, and helpful. The installation itself was completed to an exceptionally high standard. The panels were lined up and centred on the roof perfectly, and the wiring and overall finish were beautifully tidy. Every member of the team was friendly, professional, and clearly focused on delivering great service. I’m extremely pleased with the result and would highly recommend Sussex Solar Ltd.

Powerwall 3 with 23 panel, 4 array in-roof PV installation.

I came upon Sussex Solar as an approved installer of the Tesla Powerwall3 from the Tesla website. I'd been considering a solar PV install after door dropped leaflets from Surrey County Council 'Solar Together' scheme, but decided an on-roof system was probably not a good idea for an ageing roof. Sussex Solar offer the in-roof GSE manufactured system with options for PV panels and would work with a roofing contractor of my choice as I decided the roof covering (tiles) really needed changing. Andy made the initial site visit and talked through options and specified the system to maximise the number of PV panels possible on our various roof pitches - why pay for tiles when you can cover the area with a PV panel. We had to delay the start due to injury to our roofing contractor and Sussex Solar were happy to reschedule (more than once). We have had several team members visit on several days and all were courteous and polite, in spite of working in a heat wave on the roof one day and enduring heavy rain another. The installation is now complete, with testing and commissioning of the system being quick and efficient. We are now generating more than enough electrical power for our daily needs - the installation has been installed tidily and now sits in the background working it's magic. Andy has had 'eyes-on' throughout the process to ensure it was installed to his high standards. A big thank you to all at Sussex Solar including the admin staff!

If a job’s worth doing, it’s worth doing well…and that’s what you get with Sussex Solar. The site visit with Dom was very helpful and answered a lot of my questions and made sure there wouldn’t be problems once work started. Simon did a lovely job on the panels with Josh, managing to feed the cables in the loft through folds in the roofing felt rather than piercing it. He was ably assisted by Sam who did the cabling - I was delighted that he found a way of routing the cable which didn’t have to go through the main house. And then came Jake and Wes to complete the electrics work - they were fantastic and the finished article really is a thing of beauty! Then there was a visit from a director (Andy) to make sure all was well, which really underlines the commitment to quality. And I have to include in that Charlotte who organised the schedule so well, and Cherelle who handled my various phone queries with great patience! Sussex Solar really were a pleasure to do business with.

We are delighted by the installation of solar panels and Tesla Powerwall and by the way it was managed and carried out - expertly and efficiently. The installation was completed to a high standard and has been working very well since it was switched on. Please pass on our grateful thanks to all your staff for a super job. Our low-pitched roof no doubt made the work more problematic and unpleasant for them but they were always pleasant and polite to us without a single complaint! For us the installation was completely stress free, the work was checked afterwards and the operation of the complete system and Tesla app carefully explained to us. Well done! Thank you once again. I would definitely recommend your company to my family and friends.
