Another good job for us by Sussex Solar
Customer Service
Quality
Value
Sussex Solar have been back to do another job for us! I think we first used them about 16 years ago to install a solar thermal system. Next came a solar PV system. Then about 3 years ago a 12kw Vaillant air source heat pump to replace our gas boiler. Now, more PV panels and a Tesla Powerwall. In each case, they gave good advice, designed a robust system, and installed it to a high standard on time and on budget. The few items of servicing that have been necessary have also been handled well. I highly recommend them for the range of products and services they offer.

Decided to invest in Roof Solar PV panels, Tesla Powerwall 3 and Zappi charger. From first contact with Sussex Solar in December, through reviewing our options, agreeing a project and the completion of the installation at the end of January, the whole process was straightforward and very professional. What I valued most was the care and quality of work carried out by every member of their team. It was a pleasure to have them work at our home. In addition, the communication with their office planning team was first class. Our Solar Thermal system was also serviced again, as part of the overall project. System working to plan and when the sun shines, wow!!

Delighted with Powerwall3 product for Load Shifting, also excellent installation process, efficiency, speed of quote and answers to questions. Everything I wished for was achieved. Electrical work neat, tidy, and proficient. The standout feature is the professional but positive likeable attitudes of all staff and business owners. I will not hesitate to select Sussex Solar in future, if or when I consider maybe solar, heat pump, or another battery. A pleasure when first time using a new supplier that they not only meet but exceed expectations.

ASHP Heating Project
Customer Service
Quality
Value
I came across Sussex Solar while researching ASHP heating solutions through Heat Geek, and I was pleased to find that they are a recommended installer by Vaillant. Andy from Sussex Solar promptly visited to assess my project, taking detailed measurements and photos. Within a week or so, I received a comprehensive quote from them. While I had other companies provide quotes, Sussex Solar stood out for their clear understanding of my project requirements and timelines. What has impressed me was their willingness to collaborate and adapt to my needs. Throughout the project, communication with Sussex Solar has been good, shout out to Charlotte here, ensuring that every step, including the BUS grant application was transparent and well-coordinated. The only issue I had was with the base of the ASHP where it was not clear from the instructions given how far it needed to be from any wall. Other than that, I wholeheartedly recommend Sussex Solar to anyone considering an ASHP related project. Special mention to Lewis, Finley, Wes and George for a faultless installation.

Sussex Solar Ltd recommended replacing my old thermal solar system which was almost 20 years old and had eventually failed with a completely new system. Lewis, Frazer, George and Finley were extremely thorough and reliable in what was appalling weather and extremely poor conditions. I am a very happy customer with their polite, knowledgeable and professional attitude. Completed job to an excellent standard giving me regular updates on progress and left everything clean and tidy. Charlotte and Amanda were very polite, friendly and professional and arranged everything very promptly at a very competitive price. The work was completed to the agreed schedule and budget. Thank you! I will have no hesitation in using them again and would be happy to recommend.

Sussex Solar are a phenomenal, customer centred business and I wouldn't hesitate to use them again, nor to recommend them wholeheartedly. They not only communicated with us promptly and kept up informed throughout the process of having our solar panels fitted, but they advised us about the planning process with the local council and communicated with our roofers to ensure the entire build went smoothly. I can't recommend them highly enough, they are an incredibly caring family run business and were professional and polite at all times.

Impressive Work and Workers

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 intelligent nature of my discussion with the boss on his survey visit and with all the other Which reviews like these. 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 complete 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 efficient, so as a result my certificates and approvals from the power network were obtained quickly, enabling me to apply for an export tariff. The system is working just fine but I'm left thinking that if I need a response from the company it will be good.

I have been using Sussex Solar for a number of years now since they installed a battery and took over the servicing of my system. They have always provided a first class, reliable and friendly service, and always been prepared to go the extra mile to solve a problem. I recently decided that I wanted to replace my ASHP which was proving unreliable and they did all the necessary work to establish the best model to work with my system and then installed it very efficiently. I take great comfort in knowing that I have them on my side and able to cope with any problem that my somewhat complicated system might throw up.

I am delighted with the installation of solar panels, battery and heat pumps by Sussex Solar and I appreciated their flexibility over planning issues and being able to complete the project so swiftly after permission was granted. It was a pleasure to have their expert team in every nook and cranny of the house for two weeks and they left everything tidy and organised. The new plumbing for the heat pumps in the garage is a work of art and the wiring complements it all admirably. I have no hesitation in recommending Sussex Solar with their expertise in the installation of the latest renewable energy technology.

This was a solar panel and battery installation and after unsatisfactory quotes from 3 companies I bought Which? magazine. I wanted a knowledgeable local trader and found Sussex Solar via Which? I have been completely satisfied with Sussex Solar from the first visit. I understood the quotation and the work to be done and the potential benefits. Communication from start to finish was excellent and the work was completed on schedule and to budget. Sussex Solar is a family owned company with a professional team in every part of the company. The team are happy and they all wish for their customers to be happy too. I strongly recommend Sussex Solar for your Solar Panel, Heat Pump or Energy Advice requirements.

Sussex Solar have been excellent. The initial survey was comprehensive and clear. They were open about the lead-times involved - it’s worth waiting for a quality job. The installation team were hard-working, competent and a pleasure to deal with, as are the office staff. They explained things clearly and patiently, so that we now firmly engaged with monitoring the benefits of the system. Sussex Solar were not the cheapest quote we received but my judgement is that they are the best value-for-money overall.

Sussex Solar fitted our system over three days, in line with expectations set when the contract was signed. We were kept informed of minor changes to the original plan. All the kit was delivered in time and the electricians took pains to make sure all was working and that we understood how everything operated. The team was polite and the work carried our efficiently and professionally.

A fantastic local, family company who have been in the solar panel and battery business for decades. Very helpful, and they did a fantastic job. Andy is extremely approachable and informative, and the office did a great job in keeping me updated. His wife works in the office, and his son is the electrician that helps set it all up. It is really nice to have a family company running this, as it is easy to speak to someone very quickly. A really neat and tidy job and we are very happy. Several other friends have used them and all sing their praises - after using them, I fully agree.

Sussex Solar installed solar panels for us in March 2023 and a Tesla Powerwall in May 2023. The whole setup has worked flawlessly so far and we are very pleased with it. I would highly recommend Sussex Solar to anyone thinking of installing a solar energy system. The service has been excellent - everything carried out to plan, flexibility in dates to fit around our schedule and great communication about what was happening and when. The guys that came round to do the installation were great - polite, hard-working and explained clearly to us what they were doing and how the system would work. We look forward to many years of clean power to come.
