Project Overview
ProStar Energy partnered with St Francis Church in Salisbury to deliver a tailored solar PV system that significantly reduces electricity costs while supporting the church’s environmental values.
As energy bills rise across the UK, this church took a proactive step toward energy independence and long-term sustainability.
With large roof space, consistent daytime usage, and a strong commitment to stewardship, St Francis Church was the ideal candidate for a high-efficiency commercial solar and battery system.
The Installation
Our team installed a 20.7 kWp rooftop solar PV system alongside a 9.6 kWh battery to maximise self-consumption of generated electricity.
This smart setup enables the church to power lighting, heating, and community events using clean solar energy during the day while storing surplus energy for use in the evening or on low-sunlight days.
The installation was carried out with great care to respect the architectural and spiritual significance of the building, ensuring the system blended seamlessly with the structure and surroundings.
Financial Benefits
The total project cost of £21,301 is projected to yield savings of £4,537 in the first year alone.
This results in a 21.29% annual return on investment (ROI), with a full payback expected in just 4 years and 6 months.
Beyond this point, the system will continue to generate free, renewable electricity—saving the church tens of thousands of pounds over its lifetime.
Environmental Impact
The solar installation at St Francis Church will prevent approximately 5 tonnes of CO₂ emissions each year, supporting the Church of England’s net-zero carbon target and the local Salisbury community’s commitment to sustainability.
This project not only benefits the building but also sets a powerful example of environmental leadership within the faith community.
A Bright Example for Other Churches
This project demonstrates how churches and religious institutions can make smart use of renewable energy to lower bills, protect the planet, and invest in their future.
The system is designed to operate efficiently for 25+ years, delivering both peace of mind and tangible benefits to the church and its congregation.
