How we chose the best solar panel companies in London
- Installation quality: We evaluated the certifications, training, and experience of each company. Workmanship guarantees must be provided.
- Product quality: We assessed the quality of the solar panels and components used by each provider. We looked into efficiency ratings, manufacturer partnerships, and coverage on tools (e.g., panels, inverters, and batteries).
- Pricing: We compared pricing structures to see whether companies were upfront about costs and avoided hidden fees.
- Customer service: We reviewed how responsive and supportive each company was throughout the installation process.
- Aftercare support: We looked into post-installation services. Companies must offer long-term coverage and easy access to maintenance or troubleshooting.
1. Emyra Solar

Location: Solar, Emyra, 17 Hanover Square, London W1S 1BN
Contact: +44 808 280 0056
Opening Hours: Monday – Friday: 9:00 AM – 5:00 PM
Emyra Solar wins in terms of range. Their solutions cover residential, commercial, and industrial properties. They also offer on-grid, off-grid, and hybrid systems.
They specialise in high-performance solar PV installations in London, so we’re confident in their skills. In fact, they have over 10 years of experience in quality workmanship.
We liked how the installation is tailored to each property’s roof or ground space. The use of drone mapping and 3D assessments really ensures a precise approach.
Another great part of their installation process is their communication. There are enough consultations, updates, and follow-ups until completion.
The guarantee is robust. Extended warranties are available, including a 50-year coverage for systems and monitoring.
Pricing is transparent and competitive. According to clients, they found no hidden fees in their bills. They’re up front about quotes on both components and labor, too.
The downside is that the installation may experience some delays due to site conditions. Proper and in-depth assessments can help prevent this.
Very polished and reliable
“Went ahead with a solar system paired with a Tesla battery and I’m extremely pleased with the outcome. The installation was well organised, everything was set up properly, and the system was explained in detail. The battery integration works seamlessly and the whole setup feels very polished and reliable.”
– Qaim Shah, Google Review
A system that makes a difference
“After comparing a few companies,we choose this one because they were upfront and easy to deal with. The 5.5kW solar system was installed neatly, with clear explanations throughout the day. No hidden costs, no surprises – just solid work and a system that’s already making a difference.”

SogoSolar specialises in complex remediation and legacy system upgrades. This includes decommissioning old PV arrays and safely recommissioning improved systems.
We liked how they focus on highly customised system design work. They even collaborate directly with architects and contractors for multi-stage projects.
The range of solutions is great. They offer advanced energy solutions such as the Tesla Powerwall battery integration.
As for the installation process, we appreciate how they seamlessly work through roofing works, scaffolding, and structural improvements.
We liked this approach because it is much safer, reducing property risks.
Communication during the project is timely, accurate, and transparent.
Pricing is competitive and reasonable given the quality of the components. Some clients even revealed to us that their installations were projected to pay for themselves in just 5 years.
However, in some projects, clients experienced minor admin delays. There’s also scheduling pressure during peak demands, so calling ahead is recommended.
Provided great help
“A fantastic service from Ben and his Team. We have now had the panels for 2 years and on the odd occasion when we’ve needed a bit of technical advice Ben has always been available and provided great help. Would not hesitate to recommend SogoSolar to others thinking of having solar panels installed.”
– Dave Rutter, Google Review
Very professional approach
“I contacted Ben as the company who installed our solar array no longer trade and we were experiencing leaks into the attic. Ben arranged for a roofing company to assess the damage then coordinated the repair which involved removal of the panels, mending the roof and replacing the panels. He also arranged the scaffolding. All involved communicated well so we knew what was happening at all times. Very professional, thank you!”

The installation quality highlights both engineering precision and visual aesthetics. Looking through past projects, we can clearly see how much attention was used to make rooflines appear neat.
The team was punctual and courteous. During on-site work, clients said they were efficient without cutting corners.
As for post-installation, the support includes inspections and responsive technical guidance. There’s involvement beyond handover, which we truly liked.
Installations come with a 10-year workmanship guarantee and 25-year panel warranties.

4. Fusion Services Ltd

Location: St Ann’s House, 111 Guildford Rd, Lightwater GU18 5RA
Contact: +44 20 80500 548
Opening Hours: Open 24 Hours
Fusion Services impressed us with their solar installation process. They’re structured and follow a safety-focused workflow.
Every stage was tested to meet energy efficiency and safety standards. Considering the approach, we feel reassured about the quality of their workmanship.
Beyond solar panel installations, one thing that sets them apart is their emergency response. For cases like a lack of heating, they can provide temporary radiators.
According to clients, they were able to respond even in the middle of the night. This is the kind of customer support we wanted for long-term care.
Pricing is competitive and fair relative to the scope of work. In fact, a few clients even got deals on solar installations where applicable.
Based on our firsthand experience, communication is fast, reliable, and consistent.
If there’s a downside, it’s that this isn’t a company specializing in solar panels alone. This may drive clients away who prefer exact expertise in this area.
High level of customer care
“Its not often we take time out to do reviews but We found the level of service and Customer care from Fusion was exceptional ,which from our experiense is quite refreshing in this modern age. From the first contact when they found out we had no heating they pulled out all the stops. Even arriving late in the evening with some emergency oil filled radiators.. We now have a new central heating system installed and have no hesitation in recommending this company. Thank you Sam and the Fusion Team.”
– Stanley Thompson, Google Review
Extremely easy and stress-free
“Sam and his team are exceptional. We required a lot of work after purchasing a property, including a repipe and new boiler. The whole process was extremely easy and made stress free by Fusion Services, I could not recommend them any more! I have finally found a reliable company that will always answer and turn up when they say they will. They have now quoted my bathroom and will be returning once I have the funds to proceed. Thank you for being amazing!”

5. Joju Solar

Contact: +44 20 7697 1000

We liked Joju’s wide range of solar energy solutions. Some of their key offerings include solar panels, battery storage, and EV charging systems.
The quality of their workmanship met our standards. Installations are neat, tidy, and aesthetically considerate.
We like how they go out of their way to maintain the look of the client’s property.
On top of that, the designs are future-proof. This gives room for additional panels and storage expansions when necessary.
Communication is clear, consistent, and proactive. Clients are kept fully informed throughout the process, from initial survey to follow-ups.
Rates are competitive and transparent. While not the cheapest in this list, they deliver value through consistently successful turnarounds.
Finally, they handle aftercare well. For instance, they address issues like faulty components promptly without major disruptions.
The only issues we encountered were that there were delays due to a lack of supply. However, these are very rare instances.
A pleasure to work with
“JoJu Solar is a superb organisation with dedicated, experienced people who really care about providing first rate solutions. They installed 73 panels on our church which will save us many thousands of pounds every year on our electricity bills. The installers worked hard to maintain the aesthetics of the building and were happy to schedule the noisier work around our activities to minimise disruption. They were a pleasure to work with at all stages of the project. Highly recommended.”
– Quentin Bradley, Google Review
Well-informed and updated
“Many thanks to team of Joju Solar, I have a very good experience for the in roof solar panel and Tesla Powerwall installation by them. I’m well informed and updated during whole process from survey to installation. The logistics was so good that everything came at the right time for installation. There was heavy rain after the installation and there was no problem. Trustworthy and highly recommended.”
