Orange Solar Systems Ltd. is praised for knowledgeable advice, clear communication and tidy, efficient installations, from solar PV panels and inverters to home battery storage. Customers often mention friendly, professional teams, competitive pricing, helpful paperwork and strong after-care, with systems performing well and reducing energy costs. One review reports a serious delay and poor communication while resolving a faulty battery installation, contrasting with the otherwise consistently positive experiences.
I’m writing about our experience with Orange Solar Ltd. We had solar PV panels (15), an Anker Solix X1 three-phase battery inverter and a 20 kWh battery (5 kWh x 4), plus the Anker Power Dock Pro whole-home backup gateway installed. John Arnold was referred to me by a colleague from work. After a negative experience with a building contractor in the past, a positive, no-reservation recommendation from my colleague was worth its weight in gold. I was not disappointed. Flexibility in installation and prompt removal of the scaffolding were good examples. It went up on a Friday, work commenced and was completed the following Monday, and it was removed by the end of the day Wednesday. As my new neighbours' Sky TV was affected by the scaffolding, John moved things around to have it removed without delay. The installation went as planned, executed neatly and professionally. One small commissioning issue was resolved by Anker Technical, liaising with John, in less than 24 hrs. The system has been installed now for just over a week and is working perfectly. I’d highly recommend Orange Solar Ltd and would not hesitate to use them again in the future.
Orange Solar systems Ltd have just installed Solar Systems to our rental properties and cannot praise them enough. Great Service, great price, great communication and very efficient with paperwork, would thoroughly recommend This company - thank you John and team!!
Orange Solar Systems installed our PV system back in 2011, it paid for itself several years ago. We love looking at the little monitor to see what we are generating. We recently had them back to add a battery, so we now save even more overnight. I was great to see that some of the original team still work for the company all these years later. Highly recommended.
Having looked through the other reviews they couldn't be more different than my experience. I recently had Orange fit a home battery and gateway to complement an existing solar array. The system didn't work from day 1 and it was 4 weeks later before John or Alan could organise a visit to rectify, citing being too busy. At that point I had the installation removed and demanded a full refund. At no point did John or Alan call me to apologise or try to resolve other than making me feel like a nuisance when I chased them. Customer service was non- existent. Apparently new customers are the priority - not resolving a faulty install. Total clown show.
The team have just installed 77 panels on our workshop roof and did a fantastic job. The team were so friendly and the communication was great throughout. A pleasure to deal with.
Orange Solar Systems supplied and installed a Sigenergy Solar and Battery system for me recently and they did an excellent job. The guys did were very tidy in their work and very efficient. The system is working flawlessly and is already saving me on my electricity bill. I did a lot of research and spoke to a lot of companies before choosing them. I highly recommend Orange Solar Systems, and their prices are very competitive.
OrangeSolar have supported us over seven years, starting with a SolarEdge PV array and later adding three GivEnergy batteries. Every installation has been clean, careful, and well‑explained. The system has worked perfectly from day one and continues to outperform our expectations daily. Solar and storage integrate seamlessly, and the whole setup is already proving ideal for emerging Time‑of‑Use tariffs. Excellent service, strong after‑care, and a team we trust completely.
Matt and the team were very knowledgable when scoping and installing our system. The support even a couple of years after install was incredible. We had some issues caused by a third party and they were out the next day fixing it. Brilliant
They provided excellent service from start to finish. The installation was quick, tidy, and professional. My solar panels are working perfectly, and I’m already seeing the savings on my bills.
Orange Solar systems installed a large 52 panel system with 12kW inverter and 32kWh battery system at my home in April 2025. John was exceptionally helpful and knowledgable during the design process. He answered many questions about the system which helped guide us to the optimal brand of system that would suit our home automation requirements. The install was completed in 2 phases on 4 separate roof areas, included sloped tile, metal cladding and flat roof areas. The installers were excellent; Punctual, hard working, efficient, polite, tidy and skillful. They worked very collaboratively with myself in particular when it came to the various cable runs across the property. It was a large, complex install but it was all managed and executed flawlessly. The performance of the system has exceeded our expectations. Thank you. I would highly recommend Orange.
Honest and professional, what more could you ask.
After much research I selected Orange and was very glad that I did so. Matt did the original survey and was so professional and helpful that I had no problem in deciding to go forward with the installation. John program managed and together with Matt progressed the installation in a fast and efficient manner. Yes it costs money, but I have found the reward in much reduced electricity charges plus financial returns from my provider. I think that it has been one of the best things that I have done and have no regrets. Orange Solar are a credit and a company you can rely on.
Orange Solar did an excellent job! The team was professional, efficient, and the installation process was smooth. Highly recommend their services!
“It doesn’t hurt to ask!” An “ORANGE SOLAR” van caught my eye, parked in Dibden Purlieu. I approached the van and was greeted by a very personable guy. I enquired whether his company were able to fix my solar panels which I thought were failing as the readings were particularly low. Alan, as I found out later was his name, said they were working in the area.. and their reputation was spreading via word of mouth. He wasn’t able to say if my request was possible but he’d pass my information onto the boss engineer John.. who would contact me. Good to his word, John sent round an engineer to view my problem. Tarsem was very polite, and thorough and reassured me my panels were working fine, and it was the weather which had caused the glitch. I was Soo relieved, and grateful for the service I had received from Orange Solar.. I can see why they are getting more work in the area, and felt as a local of they deserved recognition.
I rang several companies for a quote and advice on a new inverter for our existing solar panels. I received 3 calls back with Orange Solar Systems being the first. John was not a hard salesman and explained that he would be happy to come and check to ensure that the panels were working effectively. Having considered all 3 quotes we decided to go with Orange as although it wasn't the cheapest, which was ridiculously low, Orange was a local company. The 2 guys who came to check the system and make the installation were polite and extremely helpful. We are very happy with our new inverter and so is our smart meter!!
The service i received was 100% throughout. Alan the advisor was very informative,professional and coordinated to total satisfaction. The scaffolder and fitters were the best in the trade and very friendly. A very tidy job all round.
The service we received from Orange Solar Systems was first class. The installation was conducted professionally and speedily.
