Great solar and battery installation
Customer Service

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

The team were so reliable - turning up when they said they would to undertake whatever task they had communicated in advance they would be there to do. Would highly recommend this team of clear industry professionals who really know their stuff!

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 and team

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.

Sussex Solar were very helpful in discussing options for solar panels, and, over many weeks, looking at various different tariffs. The installation and commissioning was quick and efficient. I would recommend them to anyone for their attentive customer service.

Having previously purchased an EV we were keen to further improve our green credentials. We were anxious to find an installer we could trust as it appears a minefield. Fortunately a friend of my wife recommended their services as she knew them well and her parents had been delighted with their work. From the first contact they were polite and efficient arranging for Andy (owner) to visit shortly afterwards with a colleague. They spent an hour explaining and answering questions we had, so we felt we had a thorough understanding of the systems and options available. A detailed survey and assessment was carried out and detailed report provided. A tailored installation schedule was agreed, initially proceeding with solar panels and battery followed 5 months later (at our request) by the air source heat pump. The whole installation team were very efficient, friendly and professional throughout tidying up at the end of each day and providing detailed explanations for use of the system. We have been transfixed and delighted with the performance of the solar panels and battery and are hopeful and confident the Air Source Heat Pump will perform as expected over the winter. Many thanks to all the team who genuinely seem to care about the service provided.

Absolutely Splendid job, they came to carry out the installation of the solar panels and battery system when they they had said. The staff where very polite and helpful, after completion I was contacted to say that they would be returning as when the photographs of the panel installation were viewed that they where not central on the roof. They returned centralised the panels looks great. Highly recommend them.

Thank you for your lovely comments about our work. As you said, our Technical Director was not completely satisfied with the alignment of the panels and asked our team to make adjustments so everything was absolutely perfect before signing off your installation.
