Swanlea School Solar Installation by Solar4Business

Project Overview:

Swanlea School, located in the heart of London, is a prominent secondary educational institution known for its commitment to excellence in student outcomes. With over 1000 students and a dedication to providing a top-tier learning environment, the school has always sought innovative ways to invest in its future. In pursuit of this goal, Swanlea School was awarded a substantial government grant earmarked for energy efficiency upgrades, prompting the school’s leadership to consider transitioning to cleaner, renewable energy sources.

Recognising the need to embrace sustainable energy solutions and fulfill their responsibility to future generations, Swanlea School decided to harness the power of the sun. The choice was clear: they embarked on a solar energy project, a decision fully supported by both students and parents. To execute this ambitious initiative, Swanlea School partnered with Solar4Business. The collaboration aimed to install solar panels on Swanlea School’s premises and eventually extend this renewable energy solution to 96 more schools within their group.


Solar4Business successfully executed the solar energy project at Swanlea School, providing the institution with a sustainable and eco-friendly energy source. The key details of the solar installation include:

  • System Output: 326.02 kW
  • Solar Panels: 805 x 405W JA Solar Panels with a 25-year warranty
  • Inverter: 1 x Solis – 255kW 5G 3 Phase Inverter with 14 MPPT High Voltage, SPD, and DC protection, backed by a 20-year warranty
  • Accredited Installation: The installation was performed by NICEIC or NAPIT Accredited employees of Solar4Business, ensuring the highest standards of quality and safety.

5-Year Savings:

  1. Projected Bill Without Solar: Before the solar installation, Swanlea School was spending a significant £272,000 per year on energy expenses.
  2. Solar Savings: With the new solar energy system in place, Swanlea School is projected to save an impressive £147,000 per year on energy costs.
  3. Lifetime Savings: Over the course of five years, the school is expected to accumulate substantial savings, amounting to an estimated £3.6 million.
  4. Return on Investment (ROI): The investment in the solar energy project is expected to pay off remarkably quickly, with a projected ROI of just 1.8 years.


Swanlea School’s decision to transition to solar energy not only demonstrates their commitment to sustainability but also serves as an inspiring example for educational institutions looking to reduce their carbon footprint while saving significantly on energy costs. Solar4Business proved to be the ideal partner for implementing this project, delivering outstanding results that contribute to a brighter, more sustainable future for Swanlea School and the wider educational community.

With the success of the Swanlea School project, Solar4Business is poised to replicate this achievement by installing solar systems in an additional 96 schools within the group. As more educational institutions follow this path towards renewable energy, the future looks brighter for both the environment and their budgets.
