DES Renewable Energy Limited

Excellent service and flawless system performance! I had a fantastic experience working with DES Renewable Energy on the installation of our solar panel system with Tesla Powerwall 3 and EV charger. From the initial consultation to handling the DNO approval, their team was clear, professional, and responsive. Although the original plan was for a later install, DES managed to bring the installation forward — which was a very welcome surprise. The system has now been running flawlessly for 5 months, and I’m very pleased with the overall performance and the choice to go with DES. Special thanks to Brenda, Darren, and the wider team for their support and flexibility. I would gladly recommend DES to anyone looking for a reliable solar and battery solution in the South of England.

Outstanding from start to finish; from having an in depth consultation to physically having the system installed. The system has been quietly generating over the summer months (and in the sunny winter ones too). Gone is the stress of leaving the hot tub on or forgetting to switch a light off at the end of the night and getting fleeced by the energy company . My energy bill has dropped significantly saving me a fortune. Thank you DES.

I’m extremely pleased with the service provided by DES Renewable Energy Ltd, who recently installed a Solar PV and battery storage system at my property. From the outset, their communication was prompt, clear, and professional. They took the time to explain all the available options in detail and walked me through the entire installation process, which gave me real confidence in my decision. The onsite team were excellent: Stuart and Paul carried out the solar panel installation, while Jack and Spencer handled the electrical side. Everyone was friendly, knowledgeable, and very efficient. The whole installation was completed quickly, smoothly, and without any issues, taking just a day and a half. I’m very happy with the end result and wouldn’t hesitate to recommend DES Renewable Energy Ltd to anyone considering solar and battery storage.

We had an excellent experience with DES Renewable Energy for the installation of our solar panel system, Tesla battery, and Powerwall 3. From the initial consultation through to securing DNO approval, the team was clear, professional, and highly responsive throughout. The installation itself was completely stress-free, and the system has been running flawlessly since July 2025. We’re extremely happy with both the performance and our decision to choose DES. Darren from DES created a bespoke SLD tailored to our installation, which was hugely appreciated. He was brilliant to work with, as were the wider team, the subcontracted scaffolders, and the electricians. I would happily recommend DES to anyone in the South of England looking for a reliable solar and battery installer.

It's early days but I have to say I am unsure why I didn't do this many years ago... Oh yeah because of cost. DES have transformed how I view electricity usage. Fact based evidence supplied by the team at DES convinced me to invest for the future. Process to get the panels and battery went smoothly with always being kept up to date on progress and the installation was faster and simpler than I imagined. The roofers and electricians both very professional and pleasant people. Mustn't forget the scaffolders, local crew not sure from where, but very efficient. Thank you to all the team at DES

Great experience from start to finish .

Richard has created 3 proposal and answered all my questions. When install time has come, Jack, Spenser and Brandon has done splendid job, super efficient and quick.the roof work - Brandon and Spenser done it in no time and it looks great. The cabling was done by Jack - very neat and done exactly as I asked for. The unit required remote firmware upgrade, so Jack stayed back to make sure it’s all perfect and demoed it to me. Thanks guys. Super. Would 100% recommend.

DES have just completed a solar installation

DES have just completed a solar and battery installation and I am more than happy with their work ethic.Helpful, professional and thorough. Jack and Spencer (electric)) and Brendon and Steve (roof) were all very helpful, knowledgable and polite. I highly recommend DES if you are considering an installation. Five stars, Well done.

Excellent service

From our initial enquiry everything was explained clearly and several options and costings provided. We delayed making a final decision for 12 months but were never pestered or had pressure put upon us to go ahead. The installation was carried out with little disruption and all wiring and equipment installation done very neatly.

Having a single company do the whole thing is a plus

Good explanation of the system by Oliver in the sales meeting. Actual installation took two days. Great job by Ben & Spencer on electricals and Stuart & Paul on roofwork. The scaffold was up a few days in advance and afterwards, total 8 days, which I gather is about normal, but bear that in mind if you don't like to leave a house unattended when it's covered in scaffolding. Ours survived Storm Goretti, so was obviously solid (even if the team did damage my cherry tree when they dismantled it!). I like the fact that the whole team are part of DES (except the scaffolders who were MM Scaffolding in my case), so you just have one point of contact both before and after installation. Documentation was comprehensive and timely, including all the necessary certificates. When trying to assess the payback it helps to understand discounted cash flow and do your own calculations. Simply dividing the price of the system by the annual savings will give an artificially short payback period. There are inevitably many major assumptions in the illustrations in the sales pack, which could affect payback by many years. Whether the system will increase the value of your house is also a matter of opinion. You need to make sure you get on an appropriate tariff. Oliver was supposed to contact me after the installation to give guidance on this, but never did. However, it didn't matter, because ours is a Fox system (battery plus inverter) and I can highly recommend the "TonyM1958 FoxESS-Cloud" page on the github website: (sorry, Trustpilot won't let me paste a link) for fantastic guidance on understanding and using the Fox app and even programming the system yourself if you want. We're on Octopus and can recommend them. They have tariffs specifically designed for solar systems. You get paid for exporting excess energy to the grid. This takes a few weeks to kick in. Ours hasn't yet, but everything else is looking good. Even in January we have been exporting quite a bit to the grid, and the battery charging/discharging and all other aspects of the system seem to be working very well.

Great service, would highly recommend.
