    Key Considerations Before installing Ground Mount Solar on Your Commercial property
    13 Mar, 2025

    Solar energy is becoming an increasingly popular choice for businesses looking to lower their energy costs, reduce their carbon footprint, and improve sustainability. Ground-mount solar systems, in particular, provide an excellent opportunity for businesses with sufficient land to generate significant amounts of electricity. However, installing a ground-mount solar system is a complex task that requires careful planning and consideration. Below are the key factors that businesses should consider before installing a ground-mount solar system on their commercial land.

    1. Property Assessment and Available Land 

    The first and most critical step when considering a ground-mount solar installation is determining whether your property has the space to accommodate the solar panels. Ground-mounted systems typically require a larger footprint compared to roof-mounted systems, and the amount of available land will directly affect your solar potential.

    • Land Size and Layout: Assess how much open, unobstructed land is available for the installation. The more direct sunlight the site receives, the better. Ensure the land is easily accessible for equipment delivery and installation as well.
    • Soil Type and Terrain: The condition of the land is important. Certain types of soil or uneven terrain may require specialised foundations for the mounting structure. If your property is located in an area with high winds or prone to flooding, additional considerations may be necessary to ensure structural stability.

    2. Local Planning and Permitting Regulations

    In the UK, ground-mounted solar installations are subject to planning and permitting regulations, which can vary depending on the location of your property. It’s essential to understand these rules to ensure a smooth installation process.

    • Planning Permission: Unlike roof-mounted solar panels, which often don’t require planning permission in many cases, ground-mounted solar systems are more likely to require approval from local councils. The size, location, and visual impact of the installation are key factors that will influence whether planning permission is required.
    • National Grid Connection and Permissions: In addition to local planning, you may need to engage with the National Grid to arrange for connection approval and ensure that the system can be integrated into the grid. This process is important, as it involves ensuring that the amount of power you generate does not exceed the capacity of the grid in your area.
    • Environmental and Wildlife Considerations: If your property is located near a protected area, a Site of Special Scientific Interest (SSSI), or within certain heritage zones, you may face additional regulations or restrictions. It’s crucial to check for any environmental considerations that may affect installation.

    3. Solar Site Analysis

    A professional solar site assessment is essential to determine whether your site is suitable for a ground-mount solar installation. Several factors influence the efficiency of a solar system, and a site analysis can ensure that your installation is optimized for maximum energy generation.

    • Solar Irradiance and Shading: The amount of sunlight your site receives is critical for determining how much energy your system will produce. The site analysis will assess the level of solar radiation in your area and identify any potential shading from trees, buildings, or other obstacles that could reduce the efficiency of the panels.
    • Orientation and Tilt: In the UK, solar panels should typically face south to maximise sun exposure throughout the day. The angle at which the panels are tilted also plays a role in their efficiency. A professional will evaluate the best tilt angle to optimise energy generation, depending on your location and the site’s specific characteristics.

    4. Cost Considerations and Government Incentives 

    The upfront cost of a ground-mount solar system in the UK can be considerable, but there are various financial incentives and rebates that can help offset the initial investment.

    • Initial Costs: Ground-mount solar systems generally require a larger upfront investment compared to roof-mounted systems, as they involve more land preparation, materials, and installation labour. Costs will vary based on the system’s size, the quality of the equipment, and the complexity of the installation.
    • Tax Benefits: Solar investments in the UK may qualify for the Annual Investment Allowance (AIA), which can enable businesses to claim tax relief on the cost of purchasing and installing solar systems. Additionally, there may be opportunities for VAT relief, depending on your business’s setup.

    5. Energy Needs and System Size 

    An important step is to assess your business’s energy consumption and determine the appropriate size for your solar system. Understanding your energy usage will help you ensure that the installation meets your needs while avoiding unnecessary over-sizing.

    • Energy Consumption Analysis: Review your business’s electricity bills over the past year to estimate your average consumption. By calculating your annual energy usage, you can design a system that offsets a significant portion of your energy needs, potentially reducing your reliance on the grid.
    • Future Energy Requirements: It’s also important to consider your business’s future energy needs. If your energy demand is expected to increase, you may want to install a larger system now to accommodate future expansion.

    6. Choosing the Right Equipment and Installer

    Choosing the right solar panels, inverters, and mounting systems is crucial for ensuring the performance and longevity of your installation. Equally important is selecting a qualified solar installer who has experience with commercial ground-mount systems.

    • Solar Panels and Inverters: In the UK, high-efficiency solar panels that perform well in varying weather conditions are essential. Consider brands with a strong reputation and good warranty terms. Inverters, which convert the direct current (DC) power produced by the panels into alternating current (AC) for use by your business, should be chosen based on system size, efficiency, and reliability.
    • Qualified Installers: Work with an accredited and experienced installer who can guide you through the entire process, from design to installation and ongoing maintenance. Look for installers who are registered with the Microgeneration Certification Scheme (MCS), which ensures that the company meets required standards of quality and professionalism.

    7. Maintenance and Monitoring

    Although solar systems require minimal maintenance, it is important to regularly monitor and maintain the system to ensure optimal performance.

    • Monitoring: Most modern solar systems come with monitoring tools that allow you to track the performance of your system. This can help you detect any issues, such as panel shading or inverter malfunctions, before they become costly problems.
    • Cleaning and Inspections: Solar panels may need occasional cleaning, especially in areas with high dust or bird droppings, to maintain their efficiency. Regular inspections of the panels, inverters, and mounting system can help identify any issues that may arise.

    8. Environmental Impact and Corporate Sustainability

    For UK businesses, installing a ground-mount solar system is not just about significantly cutting long-term energy costs—it’s also about contributing to broader sustainability goals.

    • Reducing Carbon Footprint: Solar energy is a clean and renewable resource. By installing a solar system, you can significantly reduce your business’s carbon footprint and contribute to the UK’s efforts to meet its carbon reduction targets.
    • Improving Brand Image: Sustainability is increasingly important to customers, employees, and stakeholders. By investing in solar power, your business can position itself as an environmentally responsible company, which can improve customer loyalty and attract new clients.

    Ground-mount solar installations can offer businesses an excellent opportunity to reduce energy costs, support sustainability efforts, and increase energy independence. However, the process involves careful planning and consideration of factors such as land availability, regulatory requirements, system size, and financing. By taking the time to properly assess your property, work with experienced professionals, your business can successfully implement a ground-mount solar system that meets both your energy needs and sustainability goals.  At PowerGreen we have the expertise and in-house capability to support your business on every step of this journey.
