There’s a reason why you choose a family run business and this is one that delivers. Professional people doing a professional job. I can’t fault the team through the whole process from the initial phone contact with Charelle to the site survey and the completion of the works they definitely exceeded by expectations. From the staff in the office to the lads on the site every aspect was carried out with care and a level of professionalism that is rare these days. I cannot recommend highly enough.

The whole team at Sussex Solar has been excellent throughout. From our initial enquiry through to completing the installation of a heat pump in our 1970s 4 bed house, we could not fault the customer service. We were replacing our life-expired oil boiler system under the government Boiler Upgrade Scheme. We wanted to use a reputable local supplier with the expertise to specify reliable equipment that would integrate with our existing pressurised hot water cylinder. We felt confident that they understood our requirements and would only recommend a product if it was right for our situation. The installation work was undertaken with minimal disruption to us, by a highly professional, hard working team, and completed to a meticulous standard. Communication with us prior, during and after installation has been superb. The system was finished just before Christmas. We were apprehensive knowing that we would have a house full of people as the weather finally decided it was winter. However, the heat pump quietly ticked over, meeting all of our heating and hot water needs, and not a drop of oil was burnt to achieve it. We would thoroughly recommend Sussex Solar if you are considering upgrading to an air source heat pump.

We’ve just had Sussex Solar install some solar panels and a battery. We contacted several companies for prices, including a scheme sponsored by Surrey County Council, a couple of energy suppliers plus some local specialist installers. We soon realised that the best option was the local installers who specialise in this kind of work. The others seemed slightly off-hand and uninterested. Right from the first meeting we were impressed with Sussex Solar. No hard-sell, just useful advice. The quote was fully detailed and easy to accept (online). It wasn't the the cheapest - but it was (so far) worth the little extra we paid for the quality. There was a slight delay in getting the work done due to their commitments etc but it finally took place over 3 days in December. Everything went very smoothly from the erection of the scaffolding through the roof installation and battery installation. The whole team were professional. The roof installers even working through atrocious weather to get the panels mounted. Once the battery was installed and the whole system working everything was explained. There was a follow-up visit a week or so later to check it was all OK. The wiring in the garage is all very neat and labelled (for any future electrician working on the house). All mess cleared away. All in all, we’re very happy - now we just need some sun!

Thank you very much for your kind words about our team. We are delighted you were so pleased with our installation process and neat workmanship. As you noted, our slightly higher pricing enables us to take our time with our installations and not cut corners to save costs, resulting in neater installations and excellent customer service. We look forward to supporting your system over its lifetime.
Great solar and battery installation

We had 9 Canadian Solar panels installed with a Tesla Powerwall 3 combined battery/inverter. Sussex Solar were very professional and organised throughout the process, keeping us informed at every stage. The design and proposal from Sussex Solar were detailed and included three options for the battery/inverter. I chose the Tesla Powerwall 3 for its simplicity of operation and versatility. Sussex Solar made site visit after the installation to check everything and make sure we understood how things worked. We have moved our electricity supply from OVO to Octopus, to allow us to take advantage of the Intelligent Octopus Go tariff, to allow us to charge our electric car AND top-up the batteries on cheap overnight electricity. Having made this switch, the battery easily has enough capacity to run the house from an overnight charge. It is still early days, but we can also see on the Tesla app. that the solar panels have been providing 15% of the energy - which is not bad, considering we have only had the system for a short time in the winter months. We plan to register with the Outgoing Octopus scheme to sell any surplus energy during the summer months. In conclusion, we were very pleased with the service and quality of work from Sussex Solar and reassured by the fact that they are a well-established local supplier.

I found out about Sussex Solar through the MCS website as wanted assurance of quality work. From the start of the consultation with Andy it has been a great experience and the whole team with the installation and the whole process. Even during the installation the team were always asking questions to ensure that I was happy with the install. They also had all the information I needed to reassure me that I had made the correct decision choosing Sussex Solar. Very happy with the attention to detail and the install and final checks done.

From start to finish, Sussex Solar Ltd have provided an exemplary service during our solar panels installation. They took care of everything, from providing a competitive quote, supplying high quality solar panels and battery, installing them smoothly, obtaining all necessary permissions (ie building control, electricity company etc), and then great aftercare to show us how the app and system works, all in layperson terms. We are really pleased with the service and our 14 x 510kw panels are working great. Would highly recommend - thank you Sussex Solar.

Wonderful service all the way from the sight survey to the installation and Andy's visit to sign everything off. We choose Sussex Solar after a lot of research because they keep everything 'In House' and unlike the big companies do not use sub contractors. This meant a seamless and quick installation with high quality workmanship. Everybody from the Charlotte in the office to the installation team were extremely helpful and professional. We will be back for a heat pump next. Thank you

After looking around, I chose Sussex Solar Ltd to install a Tesla Powerwall and a 3.6 kW solar PV array on our garage roof. The entire process, from the initial visit to the installation day and post-install care, was incredibly smooth and trouble-free—a truly top-notch service all around. On the day of the installation, six engineers were sent, which ensured the process went very smoothly and efficiently. I am very pleased with my installation and would highly recommend this company to anyone considering getting solar.

Thoroughly professional installation from start to finish. From the initial meeting to the final handover, dealing with Sussex Solar has been a very positive experience. Everyone we dealt with, from the office/customer service side to the team on site, was efficient, polite and considerate. A simple example: we decided we wanted to move the EV charger, not a problem. I was expecting to fill in the old drill holes once they had finished, as it was my mess-up. I got home to find that Wes had done it, and colour-matched the mortar with the brick! That level of detail was consistent throughout the process. Thoroughly recommended.
