Shelly Motors Drives Sustainability with 100kW Solar PV System
Shelly Motors, a leading Kia dealership in Epsom, Surrey, faced astronomical electricity bills each month due to its large, energy-intensive showroom. They sought a long-term solution to reduce operating costs, improve sustainability, and safeguard against rising energy prices.
THE SOLUTION
The system now generates approximately 77,987 kWh of clean electricity annually, reducing Shelly Motors’ grid consumption by 40%. This translates into substantial savings on energy bills and a strong step toward environmental sustainability.

40% lower grid dependency
£1.5M projected lifetime profit
Rapid 2.5 year ROI
Strengthened environmental credentials
Seamless installation
Minimal distruption
40% annual savings on energy bills

With a payback period of just 2.5 years, the installation is projected to deliver over £1.5 million in profit across its 25-year lifespan — transforming the showroom’s roof into a long-term financial asset.
"We are extremely satisfied with the solar PV system installed by Magnum Electrical Ltd. Their professionalism and attention to detail ensured a smooth installation process. The system not only supports our sustainability goals but also provides significant financial savings."
