Solar PV, or photovoltaic, is a popular and sustainable way for businesses to generate their own electricity. The cost of solar PV for businesses in the UK can vary depending on a number of factors, such as the size of the system, installation costs, and government incentives.

The size of the solar PV system required by a business will depend on its energy requirements and the available roof space. A typical commercial solar PV system ranges from 10kW to 50kW, with an average cost of around £1.50 to £2 per watt installed. This means that a 10kW system would cost around £15,000 to £20,000, while a 50kW system would cost around £75,000 to £100,000. Installation costs can also vary, depending on the complexity of the installation and the location of the building. For example, if the roof is difficult to access, installation costs may be higher.
Additionally, if the building requires additional structural support to hold the solar panels, this can add to the installation costs. However, there are government incentives available to businesses that invest in solar PV. The most significant of these is the Feed-in Tariff (FiT) scheme, which pays businesses for any excess electricity they generate and feed back into the grid. The FiT scheme closed to new applicants in March 2019, but businesses that had already installed solar PV systems before this date are still eligible to receive payments.
Overall, the cost of solar PV for businesses in the UK can be significant, but it is important to consider the long-term savings and environmental benefits of investing in renewable energy. With the right system size and installation, businesses can reduce their energy bills and carbon footprint, while also benefiting from government incentives.
