Solar Panels for Commercial Parks

  • A solar park can cover the needs of multiple buildings or enterprises simultaneously, or sell the generated electricity at a “green” tariff to the open market. In Estonia, the solar energy potential is comparable to Germany – the cooler climate can even improve panel efficiency, and the long summer days provide abundant generation.

    A large solar power plant requires a significant area of land or rooftop space, but in return, it transforms this resource into a source of steady income for 25+ years. Sunlight is free, so after the park is built, operating costs are minimal, and electricity generation incurs almost no ongoing expenses. For businesses, this is an opportunity to secure large volumes of cheap energy while simultaneously contributing to the development of the country’s renewable energy sector.

Advantages of Solar Panels for Commercial Parks

  • A 1 MW power plant can produce up to 1,200 MWh per year – enough to supply hundreds of homes or dozens of businesses. The installation can cover your own energy needs and sell surplus electricity, making you a local producer and reducing dependence on the grid.

  • The energy generated either saves costs or is sold at market prices. Panels last up to 25 years, require no fuel, and investment payback is predictable. This provides stable passive income without operational surprises, with the possibility of leasing even without capital expenditures.

  • Minimal moving parts mean minimal problems. The system only requires periodic inspections and cleaning. Remote monitoring and modular design ensure uninterrupted generation. Operating costs are only a small percentage, with almost all energy converted into net profit.

  • A solar park reduces CO₂ emissions, improves ESG metrics, and enhances your company’s reputation. Investors value sustainability. The land remains yours and can be reused. The plant is silent, non-polluting, operates for decades, and helps build the image of a responsible and innovative brand.

How It Works

  • The photovoltaic cells in the panels convert sunlight into electricity (direct current). The panels are connected in groups (strings), and the current is fed into powerful industrial inverters. Inverters convert the combined high-voltage DC into industrial-standard alternating current (three-phase 400 V, 50 Hz). Through a transformer, the voltage can be stepped up to grid level (for example, 10 or 35 kV) for long-distance transmission. The electricity is then either supplied directly to nearby facilities (factories or business park buildings) or fed into the public transmission network. In the first case, the park connects to the enterprise’s internal network, reducing power drawn from the external grid. In the second case, a metering unit and a grid connection point are installed at the site boundary, through which all generated energy is sent to the utility company and sold on the market.

    Operation of the solar park is fully automated. Modern inverters are equipped with monitoring systems that transmit data on energy production, equipment status, and weather conditions to a control center. If any irregularities occur, the automation can disconnect a necessary section (for example, during overvoltage or overheating) to prevent accidents. Production and consumption balancing is handled at the grid level: when sunlight is abundant, excess energy is distributed among thousands of consumers, and when it is scarce, the grid covers the deficit from other sources.

    For solar parks designed for on-site consumption by business campuses, energy storage systems (battery modules) are often implemented. They store daytime excess and release it in the evening, smoothing load peaks and ensuring uninterrupted power supply for the enterprise.

    Creating a large solar park involves determining the optimal area, performing technical calculations, and obtaining grid connection permits. Typically, projects covering 1 hectare or more require extended approvals, but the output from such installations is significant. Once built, the solar park operates quietly and almost unnoticed, generating thousands of kilowatt-hours of clean energy daily under sunny conditions. It is a high-tech “energy factory” managed by computer algorithms, delivering benefits without constant human presence.

Government Subsidies up to 70%

  • Combined support can reach up to 70% of capital expenditures when using a mix of these instruments. Additionally, Estonia has quotas for green certificates and schemes for purchasing renewable energy at fixed tariffs, which guarantee stable revenue for your solar park.

  • The government is interested in increasing large-scale solar generation, as it contributes to energy security and climate goals. By leveraging available incentives, your solar park can become a reality with minimal risk. We support you throughout the entire process – from concept to obtaining subsidies and commissioning the station – ensuring a confident start for your business in the new energy sector.

Who It’s For

Large commercial solar parks are suitable for those who have significant available space and want to use it efficiently, gaining both energy and financial benefits. Primarily, this applies to owners of industrial areas and business parks: factories, manufacturing plants, logistics complexes, and commercial-warehouse centers. If your property includes large roofs or adjacent land, a solar park can turn these areas into a source of cheap electricity for your own operations. For example, a distribution center with a vast flat roof could host thousands of square meters of panels and almost entirely power its refrigeration units and lighting from solar energy.

  •  In Estonia, sites are already being allocated for such projects, and the government actively supports the expansion of solar generation. Your business can become part of this new energy landscape as an independent producer.

  • In summary, a commercial solar park is an ideal solution for those aiming to produce large volumes of green energy, who have the resources (land or roof space) for it, and who are focused on long-term returns. If your business plan includes reducing energy risks and generating profit from the energy sector, building your own solar power station becomes a highly attractive option.
