How do I plan and who can help me with the planning of a photovoltaic/solar PV ground-mounted system?

A ground-mounted photovoltaic system can be an effective method for producing renewable energy. Here are some steps that can be helpful when planning such a system:

Location assessment

A thorough site assessment is important to ensure its suitability. Factors such as sunlight exposure, shading, soil conditions, and slope should be taken into account.

System size: The optimal system size depends on several factors, including available space and energy demand. A ground-mounted PV system with 750 kilowatt-peak (kWp) can produce up to approximately 900,000 kilowatt-hours of electricity annually.

Substructure/frames

The photovoltaic modules are mounted on metal frames to achieve optimal orientation and tilt. Some frames even allow for partial agricultural use of the land beneath the system.

specialist company

It is advisable to commission a solar energy specialist company to plan and install the ground-mounted PV system . However, the optimal system size should be determined before a quote is prepared.

By following these steps, you can plan and install an effective and efficient ground-mounted PV system.

Suitable for:

• PV system 750 kWp and more – open-air system / open-space system / solar park

When planning a ground-mounted solar power plant, various service providers can offer support. For example, we at Xpert.Solar , together with our partners, offer a full-service concept for ground-mounted PV systems, including services for planning, quality assurance, and yield maximization.

According to various providers, solar parks can offer returns of between approximately 4% and 8% as an alternative investment, resulting from yields up to 30% higher than those of rooftop systems. The return on investment for a ground-mounted photovoltaic system is calculated by subtracting costs, interest payments, loan repayments, and taxes from the revenue generated. A ground-mounted system on one hectare of land can produce approximately 400,000 to 500,000 kilowatt-hours of electricity per year, which can lead to a profitable return.

It is important to note that investments in solar funds are typically long-term, often for at least eight years, sometimes even for 30 years. Therefore, investors should consider whether they can do without their money for that long.

Regarding the profitability of a solar park as an investment, the size of the park depends on various factors, such as its geographical location, solar irradiance potential, the technology used, and the investment costs. Therefore, it is not possible to make a precise statement about the minimum size at which a solar park becomes a profitable investment; each case must be considered individually.
