Project Overview

This case study highlights a commercial solar panel installation delivered by SESC Solutions at The Bridge House. The project demonstrates how a well-designed solar PV system can significantly reduce operating costs while delivering long-term financial and environmental benefits.

The Bridge House required a reliable and future-proof energy solution that would lower electricity bills and reduce exposure to rising energy prices. Solar power offered a clear route to achieving these goals.

The Challenge

Like many commercial properties, The Bridge House faced increasing energy costs and a need for greater control over long-term operational expenses. The client wanted a proven renewable solution that would:

  • Deliver strong annual savings
  • Offer a clear return on investment
  • Require minimal maintenance
  • Integrate seamlessly with the existing electrical infrastructure

A solar panel installation was identified as the most effective option to meet these requirements.

The Solar PV Solution

SESC Solutions designed and installed a high-performance commercial solar PV system tailored to the building’s energy usage profile.

System specification:

  • 137 × JA Solar 395W panels
  • Solis 50kW S5 inverter
  • Total installed capacity: 54.1kW
  • String inverter system
  • No battery storage

The system was designed to maximise on-site energy generation without unnecessary complexity, ensuring reliability and cost efficiency over the long term.

Installation & Delivery

The installation was completed with minimal disruption to daily operations at The Bridge House. SESC Solutions managed the project from design through to commissioning, ensuring the system was installed safely, on schedule, and in line with all relevant standards.

Clear communication and careful planning allowed the project to progress smoothly, resulting in a high-quality solar panel installation that met the client’s expectations.

System Performance & Financial Results

Since commissioning, the system has delivered strong and measurable results:

  • Annual energy production: 51,002 kWh
  • System cost: £48,500
  • First-year savings: £30,501
  • Estimated lifetime net savings: £1,121,485

These figures demonstrate a highly attractive return on investment. The system significantly reduces reliance on grid electricity while providing predictable energy cost savings year after year.

Long-Term Value

Beyond immediate financial benefits, the solar panel installation helps protect the business against future energy price increases. By generating clean electricity on site, The Bridge House has improved its long-term energy resilience while supporting wider sustainability goals.

Conclusion

This project at The Bridge House in Longham is a strong example of how a well-planned commercial solar panel installation can deliver substantial financial returns. With over £30,000 saved in the first year alone and more than £1.1 million in estimated lifetime net savings, the system shows the real-world value of investing in solar PV.

SESC Solutions continues to help businesses reduce energy costs, improve resilience, and make smarter long-term energy decisions through tailored solar installations.

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.
