Project developers like hep solar can either purchase or lease suitable land. In practice, leasing is usually preferred because it is economically more attractive for both parties: Landowners benefit from long‑term, stable income — and the project developer ties up less capital over the entire lifetime of the solar park.
No other energy source can be implemented as quickly and cost‑effectively. That’s why we develop, build, operate, and finance solar projects worldwide — together with strong partners and experienced local teams. This is our vision of a modern energy future.
Where Can Solar Installations and Battery Storage Systems Be Developed?
Photovoltaics is a highly versatile technology for generating energy. This means it can be implemented almost anywhere that sufficient land, sunlight, and environmental protection requirements are met. When combined with battery storage systems, solar power becomes dispatchable and can be fed into the grid with a time delay.
Ground‑Mounted Photovoltaics
We develop unused land and brownfield sites to build large‑scale solar installations that deliver clean, reliable, and future‑oriented energy for tomorrow — efficient, sustainable, and economically attractive for businesses and municipalities.
Agri‑Photovoltaics
Our agri‑photovoltaic solutions combine agriculture and energy generation on the same land, creating dual value for a sustainable future. With our customized agri‑PV systems, agricultural operations become even more resilient, future‑proof, and efficient.
Photovoltaics for Businesses
Become independent from rising energy costs with your own emission‑free electricity generation directly on your company’s rooftop. We handle the planning, construction, and operation of the solar system — enabling you to reduce costs and CO₂ emissions while strengthening your competitive edge.

Frequently Asked Questions About Photovoltaics
In principle, any area is suitable
… as long as it is not located within a protected zone (nature, landscape, or bird sanctuary) or classified as a peatland or floodplain. However, federal guidelines prioritize sites that are disadvantaged and socially compatible.
Solar Energy
Solar energy is one of the renewable energy sources and therefore among the most sustainable forms of energy generation. Although greenhouse gases are emitted during the production of components, the construction of the system, and its decommissioning or recycling, these emissions are fully offset after just a few years of operation.
Resource‑efficient use of materials and the preservation of material cycles are important to us. That’s why we prioritize quality and durability right from the procurement stage and source components exclusively from “Tier‑1” manufacturers certified by BloombergNEF.
The Performance of a Solar Park
… is determined by how much electricity it produces in relation to its size. To assess this, the share of the potential yield that is actually achieved is measured. In other words: its installed nominal capacity is compared with its specific yield. This allows operators to evaluate the system’s efficiency.
Solar Cells
Solar cells are the smallest building blocks of a solar power system.
They consist of thin semiconductor layers that convert sunlight into electrical power.
Solar Modules
Multiple solar cells are connected to form a solar module, which is then protected by glass and a frame.
A module is essentially the finished “solar panel” that is installed on rooftops or ground‑mounted systems.
Solar Parks
A solar park is a large‑scale power generation facility made up of hundreds or even thousands of solar modules.
These modules are mounted on racks and interconnected to produce direct current (DC).
Inverters then convert the DC electricity into grid‑compatible alternating current (AC), which is fed into the power grid.
Availability of Grid Capacity
Before a solar park is built, hep solar’s project development team checks whether the electricity generated can be fed into the existing high‑voltage grid of the local grid operator.
If the available capacity is insufficient, the costs for expanding the grid at the connection point are calculated and evaluated. Only once sufficient grid capacity is ensured is the solar park constructed.
The electricity produced is then distributed to end consumers by the grid operator.
Recycling of Photovoltaic Modules
Photovoltaic modules are primarily made of aluminum, glass, and various plastics. With today’s technology, these materials can be recycled relatively easily. The European Union currently requires a collection rate of at least 85% for the recycling of PV modules. In addition, ongoing research focuses on developing new recycling methods to ensure that no valuable raw materials are lost.
Clear Legal Requirements
At all our locations, strict legal requirements apply to the construction of solar parks and to compliance with environmental protection standards.
Therefore, even before construction begins, we obtain comprehensive environmental assessments that ensure we can meet all regulations and legal requirements once the lease expires — including those necessary for dismantling the solar park and restoring the land to its natural state.
What Role Will Solar Energy Play in the Future?
Global electricity demand continues to rise steadily. According to projections by McKinsey, it could double — or even triple — over the next 25 years. In response, countries are increasingly turning to renewable energy sources, with photovoltaics leading the way. In 2024, solar energy accounted for 40% of global new capacity additions, while fossil fuels such as coal and natural gas played an increasingly smaller role.
Community Engagement: Working Together for Future‑Oriented Solar Projects
Community engagement means actively involving local residents in the development of our solar projects. For us, this is not an add‑on — it is an essential part of project development. In doing so, we create trust, transparency, and real value for the region. Learn more about our Community Engagement.
An example from 2025: During an information event in Eppingen, we demonstrated what active community engagement can look like — through dialogue, participation, and collaborative solutions.
Why Is Community Engagement So Important for Photovoltaics?
Early dialogue builds trust: We engage with municipalities and local residents at an early stage to answer questions and address their concerns.
Identifying and Mitigating Risks: By involving local residents early on, potential risks can be identified and proactively minimized.
Maximizing Environmental Benefits: Together with municipalities, we work to enhance the positive environmental impact of our projects.
Accelerating Approval Processes: Open dialogue with local residents increases acceptance and can significantly reduce the duration of permitting procedures.
Fostering Local Innovation: Joint dialogue generates new ideas and approaches that enrich our projects while also supporting the region’s innovative capacity
