Report
Sussex Solar exemplifies outstanding customer-centric practices, and I am eager to engage their services again and wholeheartedly endorse them. Their prompt and informative communication throughout the solar panel installation process, including guidance on navigating the local council's planning procedures and liaising with our roofers, ensured a seamless build. Their professionalism and courtesy, coupled with their evident care as a family-run business, make them highly deserving of recommendation.

Report
I wanted solar panels and a battery so got estimates and surveys from three local companies, all Which Trusted Traders. Sussex Solar was not the cheapest but I was impressed by the more intelligent nature of my discussion with the boss on his survey visit and with all the other reviews. The work was commenced on the scheduled day by a team of four and despite the wet weather all outside work was completed on the first day, leaving one person to finish off all indoor work on the second day.
The workers were all friendly and responsive to queries as things were proceeding. Throughout, communications with the office were also friendly and quick, so as a result my certificates and approvals from the power network were obtained without delay, enabling me to apply for an export tariff. The workers were more impressive than the regular and the system is working just fine. I'm left feeling confident that if there's any subsequent need for support that I would get a good response from the company.

Report
In March 2023, Sussex Solar installed solar panels for us, followed by a Tesla Powerwall in May of the same year. The entire setup has performed flawlessly, and we couldn't be happier with the results. I highly recommend Sussex Solar to anyone considering a solar energy system installation. Their service has been exceptional - everything proceeded as planned, with flexibility in scheduling to accommodate our needs, and clear communication regarding the progress and timing of the work.
The installation team was outstanding - courteous, diligent, and thorough in explaining the process and system functionality to us. We eagerly anticipate enjoying many years of clean, sustainable power ahead.
