NRG have been excellent. What I like about there approach was different to others, they don't just stick the panels on the roof and leave you to it, they explain how it all works, they ask about your consumption / Tarif ETC... so they can tailor a package that suits your needs. Rob came to my house and walked around the house to explain where everything would fit, they fitted the battery storage where I wanted, not where was easiest. The install guys were brilliant, and knew their stuff, they tweaked a few things I wasn't quite happy with...and finally now I have paid, there are still things to sort out like MCS certificates, DNO export letters ETC....they have been easy to contact and nothing is too much trouble, I also have a guy called Alan who helps you get the best out of you're system, he explains how to set up your app to get the best outcomes.

I've just had a recent installation with NRG Solar, from the start Robs communication and expertise were excellent. We've had 22 panels fitted front, back and on a detached garage. I've had a 20kwh solax battery and 6kw solax IES inverter.
All the guys who came where very respectful and professional.

I really happy with the finished product it is generating and keeping me off grid better than expected.

Another point to note with NRG is their aftercare and monitoring. Rob employees Alan who is a battery specialist who will monitor and educate you on how best to use your system. He knows the ins and outs of the app gives you training and guidance on how to set everything up. My brother has had solar fitted with a well known energy firm and his experience has been much worse than mine.

I wanted to share an honest account of my experience as a customer of NRG Solar, because my installation wasn’t straightforward and the way the team handled it really mattered.
The sales stage with Rob was excellent — competitive pricing, thoughtful design discussions, and a very quick install lead time. My setup wasn’t simple either: I already had a 4 kW system from 2012 with a 3.68 kW inverter and FiT payments attached. The new project involved replacing and expanding the array to 8.37 kW, upgrading to a 6 kW inverter, adding three 9.4 kWh batteries, and keeping everything FiT‑compliant.
As with most installs, not everything went perfectly. The scaffolders arrived on the wrong day when I wasn’t home, but Rob jumped on it immediately and had it rearranged within two days. The roofers often arrived later than planned, which made my own scheduling tricky, but again Rob stayed on top of it throughout.
Craig, the electrician, was outstanding. His workmanship is extremely high quality, and he even redesigned the setup around my Zappi EV charger so the new batteries wouldn’t discharge into it.
Around 2.5 months later, we’re still working through some FiT complexities because the generation meter was counting battery charge and discharge. Rob and his team have been fully engaged with multiple suppliers (Infinity Innovations, Hanchu, etc.) to get this resolved. The back-office team is clearly learning the nuances of more complex systems, and although there were a few MCS certificate errors along the way, Rob consistently stepped in and got everything corrected.
As of today, everything has been sorted — including adding another 9.4 kWh battery so I’m ready for a future inverter upgrade to 10 or 12 kW when they’re released.
Overall, I’d describe NRG Solar and Rob as a small but highly competitive company that genuinely cares. Communication with Rob is seamless at any time of day, including weekends, and issues get resolved quickly. It’s clear he’s investing in training his team so they can handle more advanced designs without mistakes. They don’t shy away from complex challenges, and based on my experience, I wouldn’t hesitate to use them again.

I highly recommend NRG Solar Ltd. From the very start, Rob (the owner) was friendly, knowledgeable, and completely transparent. He provided a very competitive price and clearly broke down the costs for panels, inverter, and installation — something no other quote I received did. There was no pushy sales at any stage, just honest advice, and Rob was always at the end of the phone if I needed him.
The installation was excellent. Scaffolding was only up for the minimum time, and both the roofer and electrician were very professional, respectful of my property, and clearly knew what they were doing. I was kept fully informed throughout the process, and the quality of workmanship is top-notch.
The solar panel system is performing exactly as detailed in the quote. The aftercare service really sets NRG Solar apart — you get a dedicated expert to monitor your system, help fine-tune the setup, and ensure you’re using the correct solar tariffs at the right times of day. This support lasts for two years, which is invaluable as you learn how your system performs across different seasons.
Another big plus is that there are no upfront costs at all — you only pay on completion, once you’re fully satisfied. Overall, an excellent experience from start to finish. Highly recommend NRG Solar LTD.
