As the UK sets its sights on generating half of its power from renewable sources by 2030, the demand for large-scale solar farms has soared as a prominent form of clean energy. Companies, farmers, and independent landowners are recognizing the potential of utilizing their land to contribute to the production of green energy. This growing trend reflects a collective commitment to harnessing renewable resources and promoting a sustainable future.
Setting up a solar farm
When embarking on a solar energy project, securing suitable land is the first crucial step. It’s important to note that solar panel farms require a significant amount of land compared to other forms of power generation. For instance, a 1MW farm typically requires 5 to 8 acres. It’s essential to consider not only the space required for the panels but also for essential equipment such as inverters, storage batteries, and maintenance access between rows of panels.
In addition to space considerations, your chosen land must have a connection to the grid to facilitate the distribution of the generated electricity. If there is no existing connection, you will need to budget for the cost of establishing one.
Solar projects are typically developed in rural areas, with prime locations being either flat or on south-facing slopes. If you intend to convert agricultural farmland, keep in mind that stringent planning procedures are in place to protect food production. It is rare to obtain approval for highly fertile fields to be transformed into solar farms. Your best option would be to seek land that has low agricultural yield or is primarily used for grazing.
However, obtaining planning permission is only one aspect of the overall process. Developing a solar farm involves going through a rigorous set of planning procedures, which includes evaluating the suitability of the proposed site, assessing any necessary modifications to make it viable, and carefully considering the potential environmental impact, whether positive or negative, on the local surroundings.
While the construction phase itself can be completed within a few months, securing planning and approvals is the most time-consuming part of the process. The entire development timeline, from inception to operation, can span anywhere from one to three years due to the intricacies of the planning process. It is crucial to factor in this timeframe when undertaking a solar energy project.
When identifying an ideal site for a solar farm, several key factors come into play:
- Irradiance: The amount of sunlight a location receives is a crucial factor. Sites with higher irradiance levels are favourable for solar farms as they maximize energy generation.
- Topography: The elevation and slope of the land affect the amount and timing of sunlight that solar systems receive. Optimal sites have favourable topography that allows for efficient light capture.
- Proximity to Dwellings: For utility-scale solar farms, which cover vast areas, the proximity to residential areas is important to consider. Glint and glare from solar panels can impact nearby residents, so suitable distancing is necessary.
- Capacity: The site should have the capacity to accommodate a significant number of photovoltaic panels, enabling the maximization of energy production. Large-scale solar power plants can consist of thousands of panels with high production capacity.
- Grid Connection: Solar farms require connection to the electricity grid to export the generated power. This is particularly crucial for renewable energy sources like solar and wind, as their generation fluctuates, and complete energy storage is not always feasible.
- Land Classification and Type: It is preferable for solar projects to avoid occupying land suitable for housing or farming. Planning applications for solar photovoltaic cells on brownfield sites, contaminated land, industrial areas, or lower-quality agricultural land have higher chances of approval.
Once an ideal site is identified, prospective solar farm developers must consider additional factors:
- Access: Easy access to the site for construction and maintenance activities is vital.
- Site Layout: Planning an efficient and well-organized layout that maximizes solar exposure and optimizes the arrangement of panels is essential.
- Design and Appearance: The visual impact of the solar farm should be considered, ensuring it blends harmoniously with the surroundings.
- Security: Due to the valuable equipment present in solar facilities, implementing security measures such as fencing, CCTV systems, and adequate lighting is necessary to protect the infrastructure.
By carefully evaluating these factors and addressing site-specific considerations, developers can establish successful and well-designed solar farms.

The decreasing costs can be attributed to the growing popularity of solar energy, which has driven manufacturers to develop more cost-effective components. In 2019, the average price of solar panel modules was around £200,000 per megawatt or 20p per watt produced. Furthermore, economies of scale play a role, as larger capacity solar plants tend to have lower costs per watt compared to smaller installations.
However, it's important to note that the cost of solar panels is just one aspect of the overall development cost. Land and labor expenses remain significant factors. The average value of an acre of UK farmland in 2022 ranges between £7,500 and £10,000, with certain locations and accessibility influencing higher prices.
If you already own the land you plan to convert into a solar farm, you can eliminate the expense of land acquisition.
While start-up costs for solar projects are still relatively high, the ongoing costs are considerably lower. Solar plants have minimal operational and maintenance requirements, and there are no waste by-products to manage. Once you have made the initial investment, you can expect minimal operating costs to keep your solar farm running smoothly.
As the cost of solar energy continues to decline and the technology advances, investing in a solar farm offers an increasingly viable and sustainable option for businesses and landowners alike.
Be aware that with large solar projects, you don’t just need space for the solar arrays. Land is also required to house equipment like inverters, also space needs to be left between rows of solar panels for repair and maintenance access.
On the other hand, the siting and permitting process is a more complex undertaking. It typically requires obtaining various approvals and finalizing contracts, which can significantly extend the timeline. It is not uncommon for this phase to take between 3 to 5 years to ensure all the necessary regulatory requirements and agreements are met before proceeding with the solar farm development.
Once the solar farm is fully constructed and operational, its maintenance requirements are relatively minimal. Regular servicing, which typically occurs approximately 3 to 4 times per year, ensures that the system continues to perform optimally and any necessary adjustments or repairs are carried out promptly. This approach helps to uphold the efficient functioning of the solar farm throughout its operational lifespan.
The primary source of revenue for a solar farm comes from selling the electricity generated to the grid or through long-term contracts with energy buyers. The income is typically derived from two main streams:
Electricity Sales: The solar farm generates electricity, which can be sold to the local utility or power market. The revenue is determined by the electricity production, the prevailing market prices, and any applicable feed-in tariffs or subsidies.
Renewable Energy Certificates (RECs): In some regions, solar farms can generate Renewable Energy Certificates or similar environmental attributes for each unit of renewable electricity generated. These certificates can be sold to entities looking to meet their renewable energy targets or compliance obligations, providing an additional revenue stream.
To estimate the potential income, it is crucial to consider the specific factors mentioned earlier and conduct a financial analysis based on the project's unique characteristics. Factors such as system capacity, available sunlight, local electricity prices, and the duration and terms of electricity sales contracts will play a significant role in determining the financial returns of a solar farm.
It's important to consult with industry experts, solar developers, or financial advisors who can conduct a detailed feasibility study and provide accurate projections based on the specific circumstances and market conditions relevant to your solar farm project.
