I contracted with the Sussex Solar team to advise on/supply/install a heat pump heating system and batteries. I found their work to be of an extremely high standard, and completed on time. Their team are friendly, efficient and courteous, I have no hesitation in recommending them.

Having selected the system components independently, I contacted three potential suppliers from the manufacturer's approved list and cross referenced with online reviews. All suppliers were small businesses. Of the three, Sussex Solar had the best communications (very good) and were marginally cheaper, while also accommodating the number and type of panels I'd specified, even if the fit was tight on the roof. The installation took 3 days by Sussex Solar's own personnel, who worked efficiently and were very pleasant, even offering to help with moving furniture back after the internal cable installation. As part of the commissioning, Sussex Solar also assisted with the setting up of the Apps and accounts. The only subcontracted element was the scaffold and even then the selected scaffolders were efficient and friendly. There was one small issue with the commissioning, which was quickly resolved within a couple of days, though the system was operational at the end of the 3 day installation. A very satisfactory experience from the initial contact to the final commissioning, a total period of a little over 3 months (which included the G99 application and approval from the DNO).

We decided to replace our aging liquid solar panels with photovoltaic panels, following 18 years of free hot water between March and October. The original panels were maintained by Sussex Solar, and having been so pleased with their servicing it seemed a no-brainer to return to them for the installation of new panels. We were not disappointed. At every step, there was someone knowledgeable and helpful. The installation was efficient and mindful of the construction of the house. The installation team was professional and friendly. Barring the new items, you wouldn’t know that they had been here! We are truly grateful to Charlotte in the office for helping us with any queries and the documentation required for exporting to the grid.

Very good company to use, have used them before, would recommend them to others. Their workmanship is very good and professional, and they were very helpful in installing the app on my phone. They left my house 🏠 in a very clean state. Couldn't fault them one bit.

Sussex Solar was an impressive team, the first supplier I saw, and after searching the market, were best choice for me. They were knowledgeable, helpful, service-focused and patient over a long period from enquiry to final installation. Really nice people to deal with and gave great confidence in a space where many other suppliers are very sales-led. They were service-led and it really makes a difference. Did everything they said when they said they would do it, often before, and couldn’t have been more accommodating.

We are extremely pleased with our solar panel and battery installation by Dominic and his team. We were kept up to date at all time by the office and the installers. A neat and very professional job which was done on time and a pleasure to do business with a local family firm.

From the initial site visit, through the installation and commissioning of the PV panels, the battery and car charger, Sussex Solar have provided exemplary service. All those involved in the process were fully professional and the installation was completed on time, within budget and all paperwork provided efficiently. We were kept up-to-date and fully informed throughout and were impressed to receive a follow-up site visit. We would definitely recommend Dominic and all the team at Sussex Solar.
