Understanding Solar Farms

Understanding what a solar farm is and its operation is crucial in assessing its feasibility as an investment. A solar farm, solar park, solar power station, or solar plant, is essentially a large-scale, ground-mounted solar installation. It operates like a power plant, generating electricity through photovoltaic (PV) panels or other solar energy collection systems. The power generated is then fed into the local electricity grid, contributing to the overall energy mix of the region.

Types of Solar Farms for Agricultural Land

Solar farms can broadly be classified into two types – utility-scale solar farms and community solar farms.

Utility-scale solar farms are typically larger, with a capacity ranging between 1 MW and 2,000 MW. They can use the energy created on the farm and sell the generated power to utility companies, thereby serving all the utility’s customers as part of the energy mix.

Community solar farms, on the other hand, are smaller, usually under 5 MW, and serve a specific community of subscribers who have paid for a share of their power.

The Cost Aspect of Solar Farms

The cost of setting up a solar farm can fluctuate depending on factors such as the scale of the project, geographical location, and specific financial arrangements. However, as a general rough estimate, solar farm installation costs typically range between £0.73 to £0.83 per watt. This implies that a 1 megawatt (MW) solar farm would cost between £734,000 and £830,000. It’s worth noting that these costs have been on a downward trend over the years, making solar farms increasingly affordable.

Financial Benefits of Solar Farms

The financial rewards of investing in solar panels for farms can be substantial.
