Our services extend to designing and installing EV charging solutions, from large-scale car park systems to smaller business setups.

We handle everything from initial assessments and design to installation and regulatory compliance. Once your system is live, we offer ongoing monitoring and maintenance to keep it performing at its best. Additionally, we provide expert consultancy services to guide your renewable energy projects with up-to-date advice.

Installing commercial solar panels offers numerous benefits, including:

  • Lower energy bills
  • Energy independence from the National Grid
  • Reliable and sustainable energy generation
  • Predictable energy costs
  • Enhanced business reputation as an eco-friendly company moving towards carbon neutrality

Several factors influence the suitability of your roof for solar panels, including:

  • Roof orientation and angle: South-facing roofs with an angle suited to your location will receive optimal sunlight for peak performance.
  • Roof condition and structural integrity: Your roof must be strong enough to support solar panels and withstand the installation process.
  • Shading: Avoid shaded roofs as they reduce panel efficiency. Ensure the roof is free from obstructions like trees or nearby buildings.
  • Available roof space: The more space available, the more solar panels you can install to meet your energy needs.

We offer site surveys to assess your property’s suitability and provide tailored recommendations.

Our process starts with an initial consultation and site survey. We’ll assess your property, understand your energy needs, and discuss project timelines. Following this, we’ll design a custom solar PV or EV charging solution and provide a detailed quote.

Once approved, we’ll schedule the installation, ensuring a smooth process with minimal disruption to your operations. We also offer monitoring and maintenance services to keep your system running efficiently.

We offer flexible finance options, including a Power Purchase Agreement (PPA). This allows you to enjoy solar panels with no upfront costs and benefit from reduced energy rates.

In addition, grants and incentives are often available for solar installations. We recommend researching local authority grants or contacting us for advice on available funding.

Installation times depend on the complexity of your system. We’ll discuss your timeline during the site survey and work diligently to meet any deadlines.

In most cases, commercial solar installations fall under "Permitted Development" and won’t require planning permission. However, we’ll ensure full regulatory compliance as part of our design and planning process.

Commercial solar panels typically last between 25 to 30 years. To maximise lifespan, regular professional maintenance is essential.

SESC Solutions offers the following warranties:

  • PV Modules: 10-12 years for materials and workmanship, with a 25-year performance warranty (as per manufacturer guidelines).
  • Inverters: 12-year warranty (extensions available).
  • Labour: 5-year limited warranty.
  • Complete System: 5-year turnkey warranty covering the elements outlined above.

Solar panels should be kept clean for optimal performance. Regular wipe-downs may be necessary, though rain typically provides adequate cleaning. We recommend annual professional servicing to inspect and test the system, helping prevent future issues and ensuring efficient performance.

Dorian and his team and office staff have been excellent. While others who quoted for the work fail to show up or didn’t understand the requirement, or simply incorrectly specified solutions, SESC came up with a bespoke design that exceeded my expectations at a fair price. Always a pleasure to deal with. They have a great range of skills. I would highly recommend them. Great heat pump install, cylinder, UFH install and refit of existing solar thermal, and all in a super tight space.

Thank you Dorian and the team for a great Vaillant heat pump and new central heating installation. The installation took about 2.5 weeks to have everything wrapped up, as there was a slight delay in the stock of the specific radiators we wanted, but the team worked very hard indeed to successfully take on some of the challenges of the install. They were extremely tidy (the house has never been so clean!) and conscientious with their work. Dorian is a real stickler for the small details, guiding us through the install and checking exactly how we wanted everything. Since then, the system has been running really well. Very efficient, pushing over 400% for heating and hot water since the installation in September 2025, and performing very well during cold snaps. House stays a nice consistent temperature without costing a lot on our electricity bill. Having previously had electric and night storage heaters, the new system is a massive improvement. Where there have been a couple of snags, Dorian has been more than happy to check, fix, and advise in a very prompt manner. Overall, definitely recommend when considering a heat pump installation.

I am happy to recommend SESC solutions to anyone considering a solar energy system. I have been very impressed by the fantastic customer service and advice that SESC provided throughout our large domestic solar panel and battery storage installation project. The team were available day and evening to answer my many questions, and updated the quotation several times to fit our specific requirements. The SESC quotation included everything right from the start, such as scaffolding and bird guards, that were usually left out of other companies quotes, and a pre-installation assessment checked everything was in order. The installation day was even sooner than expected and the roofer and electricians were very professional and helpful, with everything arriving on site smoothly and all rubbish taken away. Following the installation, we have quickly received all the documentation to help us switch supplier and take up the SEG for exporting our excess electricity. I have every confidence that the SESC team will continue to be there on the end of the phone if I need any further advice or support in the future.

I could not recommend Steve and his team at SESC Solutions more highly and wouldn't hesitate to work with them again for future projects. SESC Solutions have helped us for both London and country projects. The work has always been completed to a high standard and the work has always been well managed with clear communication throughout. We look forward to working with SESC again soon.
