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.

We had high electric bills so I contacted Sussex Solar for a quote because they had fantastic reviews. Andy visited and I can’t praise the level of professionalism more. We moved to Sussex from Durham and finding reliable professional people has been a challenge, however, Andy was very thorough, listened to our needs/problems, surveyed our home and came to a conclusion that wasn’t expected as he advised we take a different course to solar panels. We will use Sussex Solar for a smaller project but we are taking his advice on his alternative suggestions for our requirements. Andy’s integrity, attention to detail, communication etc were of the highest order. I had my own financial services business built on trust and relationships and I would recommend Sussex Solar without any hesitance, to anyone. I know what excellent service is and how it looks and it looks like Sussex Solar.

After reading about Sussex Solar in the wonderful free distribution magazine 'All About Horsham', I had no hesitation in contacting them for a quote. Having solar panels for several years, it felt like time to acquire a battery to charge up from them to make our household energy use more efficient. The affable director, Andy, visited promptly, and I was soon sent competitive quotes matching my requirements. As soon as I accepted the one that suited me best, Sussex Solar swung into action, approaching the relevant authorities to get the necessary permission. This took a few weeks, but soon enough I was given an installation date on which Wesley and Fin turned up, working quietly and efficiently throughout the day to install my brand new battery. Immediately up and running (silently), I am delighted and have no complaints. Andy has recently returned to check that all is in order and give me final instructions on how to monitor the battery's activity using the free app I'd been shown how to download onto my smart phone. Fantastic! I would recommend Sussex Solar to anybody.

I chose Sussex Solar after getting a selection of quotes & deciding that they looked the best from both reading previous reviews & the fact that they were local. Their proposal (15 solar panels & a Powerwall3) was very detailed both in terms of what would be installed as well as the projected performance of the system & I was happy to proceed. The installation team did a great job in really horribly wet weather over a couple of days in early January & installed all the equipment where I wanted including suggesting a location for the earth rod that didn't affect my recently installed patio. The system looks very neat both in & outside & is performing well so far. In fact it managed to produce 7.8kWh the other day which I thought was pretty good for the third week of January in the UK !

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.

We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
