Commercial Solar Panels in Slough Case Study

British Gas Offices Go Green with Commercial Solar Panels in Slough

Modern Energy & Electrical Services (MEES) is proud to showcase one of our landmark projects – the installation of a 190 kWp commercial solar panel system at British Gas offices in Staines, near Slough. This large-scale project demonstrates how businesses in the area can cut costs, reduce carbon emissions, and future-proof their operations by investing in commercial solar panels in Slough.

The Challenge

British Gas, one of the UK’s leading energy suppliers, wanted to take a proactive step towards sustainability by reducing high energy bills and generating its own clean electricity. With rising operational costs, the company needed a long-term solution that provided energy security and reduced reliance on the grid.

The Solution

MEES designed and delivered a 190 kWp rooftop solar PV system, installed across multiple roof areas facing south, east, west, and north on a 10° pitch. This comprehensive system included:

• Panels: 190 x Axitec all-black mono panels (260W)

• Inverters: 5 x SolarEdge 33.3kW 3-phase inverters with arc fault detection & DC safe shutdown

• Optimisers: 95 x SolarEdge P650 optimisers (2:1 ratio)

• Cloud Monitoring: Full SolarEdge portal access for real-time performance data

• Safety Features: Type 2 AC/DC surge protection and Fire Safe shutdown capability

The Results

• Project Cost: £166,005

• Estimated Payback: 2.8 years

• Lifetime Savings: £3,138,371

• Annual CO₂ Reduction: 34.85 tonnes

• Trees Regenerated: Equivalent to 1,605 annually

By installing commercial solar panels in Slough, British Gas secured free daytime electricity, slashed annual energy bills by around 33%, and created a cleaner, more sustainable workplace.

Why SolarEdge Technology?

The SolarEdge system was chosen for its reliability, advanced safety features, and ability to increase energy output by up to 25% compared to traditional inverters. With cloud monitoring, each panel operates independently, ensuring maximum efficiency and simplified maintenance.

A Model for Businesses in Slough

This project is a clear example of how businesses in Slough and the surrounding areas can benefit from commercial solar panels. From cutting costs to reducing emissions and improving sustainability credentials, solar PV is one of the most cost-effective investments any commercial property can make.
