Solar Farm Installation: A UK Landowner & Developer Guide

As the UK moves toward cleaner, more sustainable energy, solar farms have become one of the most efficient and cost-effective ways to generate renewable electricity on a large scale. At Blue Ape Renewables, we specialise in designing, installing, and maintaining commercial and utility-scale solar farms, ensuring they are profitable, efficient, and built to last.

If you’re a landowner, investor, or developer considering a solar farm project, this guide will walk you through:

• How we evaluate land for a solar farm
• Average solar capacity per acre
• The grid connection process
• Planning approval timelines & structural engineering considerations
• How inverters transform solar power for grid use
• Grid connection agreements & potential challenges
• Funding options for solar farm projects

By the end, you’ll understand what goes into developing a successful solar farm and why Blue Ape Renewables is the go-to expert in large-scale solar PV installations.

Evaluating the Land for a Solar Farm

Before installing a solar farm, the first step is selecting the right location. At Blue Ape Renewables, we carry out a comprehensive site assessment to determine if the land is suitable for solar energy production.

Key Factors We Look for in Solar Farm Land

1️⃣ Size & Space Requirements

On average, you can install 4-5 MW of solar PV per 20 acres (approx. 200-250 kW per acre). A 1 MW solar farm typically requires 4-5 acres.

• 1 acre = ~ 250 kW
• 10 acres = ~ 2.5 MW
• 50 acres = ~ 12.5 MW
• 100 acres = ~ 25 MW

2️⃣ Solar Radiation & Orientation

South-facing, flat, or gently sloping land is ideal for maximum sunlight exposure. Shaded areas or land with significant obstructions may not be suitable.

3️⃣ Soil & Ground Conditions

The land must support the weight of solar mounting structures. Poor drainage or flood-prone areas can lead to installation complications.

4️⃣ Access & Proximity to Roads

Good site access is essential for equipment delivery, installation, and maintenance. Narrow roads or difficult terrain can increase project costs.

5️⃣ Distance to the Grid Connection Point

A solar farm must be close to a viable grid connection, or additional infrastructure will be needed. If the grid is too far away, the costs for cabling and installation may make the project unviable.

How Solar Farms Connect to the National Grid

One of the most critical steps in developing a solar farm is securing a grid connection agreement with the Distribution Network Operator (DNO). This agreement allows your solar farm to export electricity to the grid.

Steps to Secure Grid Connection Approval

• Site Evaluation – Identify the nearest grid connection point and available capacity.
• Grid Application Submission – We submit a G99 application to the DNO for approval.
• Connection Cost Assessment – The DNO provides a quote for connection costs (which varies based on distance and capacity).
• Technical Studies & Load Impact Assessment – Ensure the grid can handle the additional power.
• Final Connection Agreement – Once approved, a contract is signed to allow grid export.

Potential Challenges:

• If the local grid infrastructure is at capacity, costly upgrades may be required.
• Some DNOs impose export limits, meaning a battery storage system may be needed to regulate output.

Planning Permission for a Solar Farm

Solar farms in the UK require full planning permission, which can be a complex process.

Planning Application Timeline & Process

• Step 1: Feasibility Study (1-2 Months)
  Assess land suitability, local planning regulations, and environmental impact. Consult with local authorities and stakeholders.
• Step 2: Pre-Planning & Surveys (3-6 Months)
  Environmental Impact Assessment (EIA), Flood Risk Assessment, Glint & Glare Study, Heritage & Archaeological Reports.
• Step 3: Submit Full Planning Application (3-4 Months)
  Local councils review the application and may request modifications.
• Step 4: Planning Decision (6-12 Months Total)
  If approved, construction can begin. If rejected, modifications or appeals may be required.

Structural Engineering & Wind Load Calculations

Solar panel mounting systems must be engineered to withstand wind loads, snow loads, and soil conditions. Our structural engineers perform:

• Wind Load Calculations – Ensuring panels won’t be damaged by storms.
• Ground Mount Stability Analysis – Designing secure foundations based on soil conditions.
• Weight Distribution Studies – Preventing land subsidence and structural failures.

How Solar Farms Generate & Convert Electricity

1. Solar Panels Convert Sunlight into DC Power
2. Inverters Convert DC to Grid-Compatible AC Power
3. Transformers Step Up Voltage for Grid Distribution
4. Electricity is Fed into the National Grid

Why Inverters Are Essential

• Solar panels generate direct current (DC) electricity.
• The grid operates on alternating current (AC) at 240V/400V.
• Inverters transform DC into AC, making it usable for homes and businesses.

Funding a Solar Farm: Options & Considerations

Solar farm projects require significant upfront investment, but multiple funding models are available:

1. Self-Funded (Owner-Operator Model)

• High return on investment (ROI).
• Requires large capital outlay.

2. Power Purchase Agreements (PPA)

• A business commits to buying solar electricity at a fixed rate.
• Solar developers finance and operate the farm.

3. Government Grants & Subsidies

• Some funding may be available for community or agricultural projects.

4. Investor-Backed Funding

• Investors provide capital in exchange for a share of revenue.
