      From the time that we obtained a proposal from DES we found them helpful and informative . We were new to solar panels and they invited us to there office where we were shown what was involved. The installation went smoothly and all the staff that we came into contact with were friendly and considerate.

      Right from the outset, I received excellent advice from their knowledgeable representatives and the works were carried out using good quality materials and good building practise by all concerned with no issues at all. Everything from the erecting of the scaffolding right through to its' removal went like clockwork. Everyone of the contractors was friendly helpful and courteous. Well done. If you are interested in Solar panels I strongly recommend you contact DES Renewable Energy for advice and a quote.

      From the initial enquiry to the bespoke quote and after giving authorisation to proceed the survey was professionally carried out . The installation of the battery ,inverter and panels on the roof was carried out within two days and any mess all cleaned up. The property was left as they found it perfectly clean. Everything explained clearly and was always available for questions.Very pleased with the whole experience. Would recommend to anyone.

      What a gem of a company. 5 stars to everyone who works for DES. Every aspect of our journey has been perfect. We have been guided through the process ever since we first made contact. Special thanks to Richard Hawkesford who was so knowledgeable, Brenda and Fabiana were so efficient in the office and what can I say about Kalum the electrician....he worked so hard from start to finish. I thoroughly recommend DES.. A golden find.

      I found DES very professional from the start and glad we chose a local company rather than one of the many nationals. We were kept informed although we did experience some delays due to the weather. On completion we did have an issue with the inverter but DES worked to resolve this to our satisfaction including replacement of the Inverter. Special thank to Matt from Technical support who worked hard to resolve our issues and the system is now working perfectly and export is setup ready for sunnier weather!

      I had excellent service from DES Renewables Evergy. It was great from start to end. Reasonable prices. I was quoted double of what DES Renewables offered hence I chose to go with them for the Same or even better system. I would highly recommend them to you all. The quality of work has been top notch. Inverter and battery installed on the side of the house.

      I had existing 4 kwh solar panels but no solar batteries. I recently bought a 10kwh hybrid car that qualified me for the off peak rate with Octopus energy for 7p per kwh.
This made having battery storage fitted a good idea to utilise this off peak rate.

I contacted several battery providers who were advertising on Facebook and Google and received quotes for 10 kWh solution’s for around £5k. A lot of these companies don’t install the systems themselves but farm the work out to 3rd party installers.

Fortunately I attended the Garden Show at Broadlands Romsey and was first attracted to DES Renewables stand by a sophisticated solar panel cleaning robot they had on display.

I left them my details and shortly after a technical salesman turned up. He left a very good impression with my wife and I. He was highly knowledgeable and was able to answer technical questions directly and confidently. He immediately sized up a system that pushed all the buttons for me - 20 kwh system with 15 years guarantee which would provide me with future proofed energy storage for running the car and all appliances in a 4 bed house for a fraction more than the other suppliers were charging for system’s half the size.

On this basis I went ahead with the system which was installed by their friendly and approachable engineers who did an excellent job in installing the system over a couple of days. DES Renewables are an electrical systems installation company with 20 years of experience with qualified electricians who have been trained to professional standards in solar installations with experience in solar farms as well as domestic installations. This all added to my confidence in the company.

I am now seeing a drastic reduction in electricity cost already having slashed my monthly direct debit from £152 per month to £45 per month which includes the standing charge.

I am very happy with the service I received from this company from initial technical sales consultancy through to system installation and can thoroughly recommend them.

      Very professional approach through the whole process. From quote to survey to installation, all was very well managed, all queries responded to and a very pleasant installation team. All the equipment seems to be very good and for a competitive price.

      A great company. We have had excellent advice and guidance on the installation of solar panels, batteries etc for our Church Centre. Excellent value for money and whole sy stem is working very well. They also advised on the installation of an EDDI system to allow the panels to feed power to the immersion heater.

      I have to compliment the service I have received when DES installed Solar Power to my property. My 3-storey property only has electricity for power which means that heating is expensive when powered solely from the grid. The DES Sales Team understood the complexity of the issues faced and made a proposal to maximise the impact Solar could make to my bills. The survey engineer made no changes to this proposal as it was a good solution.All in all, these guys should be contacted when considering Solar Installations.

      I selected DES after being let down by a previous large national solar installer. DES picked up the project suggested a different approach , completed the DNO G99 approval without needing to restart it and implemented a great ground mounted installation to integrate with my existing 2011 Solar setup. I now have my existing Fronius 5KW inverter + 6.5 KW panels, plus new 7.3kw panel ground array, Solis Inverter, Givenergy 3.5kw A/C coupled inverter and 2 x 9.5kw Givenergy Batteries. Plus a Givenergy car charger.To save money on the project we agreed I would do the ground work and lay the armoured cable to the "garage" where all the new kit and existing Kit would be housed. DES were very flexible as to the installation date as the weather was pretty awful and delayed some of the ground preparations.They did a very good job with the installation going above and beyond to ensure it was safe and a professional finish.The system works extremely well and allows me to monitor all of the solar, which is something I could not do on the old system.If you want a solid reliable company with excellent pre and post customer support. I cannot recommend DES enough.A+++

      Really pleased with DES Renewable throughout the process of having solar PV and batteries installed. The sales team were very open and informative without any pressure. The surveyor was pragmatic and helpful - my roof has a few constraints so they did well to maximise the number of panels. The installers were prompt and very tidy. Overall a great experience, I have also bought more batteries through DES and that went smoothly as well.

      DES Renewable Energy installed our solar panel system and we were impressed with their service and products. We also liked the fact that they are local and all their people (apart from scaffolders) are directly employed . We needed planning permission and they provided all the info they could apart from scale plans. All the team were professional, friendly and helpful. The completed install was nice and tidy and is working well.

      Jason and the team at DES installed a new Victron system for me. They worked very hard ahead of time to design a well balanced 9kw system and the prep work paid off with an incredibly smooth 2 day install. The on site crew were professional at all times and made short work of a complicated install. A few minor niggles on the way through was inevitable but they were all resolved quickly and courteously. I wouldn't hesitate to recommend them.
