One of the biggest reasons for business owners making the decision to install solar is for financial purposes. At current installation costs, a solar photovoltaic system delivers electricity at a rate of around 5 pence per kWh including Operations & Maintenance costs.

This compares with the current grid supplied rate of approximately 15p per unit. Therefore, with ROI periods of approximately 5 years, businesses in the UK are seeing significant returns in electricity savings allowing their businesses to flourish, reducing the burden of rising grid supplied electricity costs and future-proofing a renewable source of electricity for years to come.

With a solar installation, the commercial sector can forward buy a significant portion of electricity for the next 25 years at a fixed price of around a third of what is paid now.

This supply cost won’t go up, it attracts no storage costs, and it can be exported to the grid taking advantage of the Smart Export Guarantee.
