Open Space Project Development
We conduct project development for large-scale open space projects on behalf of Trianel GmbH. Trianel GmbH is a network of 58 municipal utilities. Additionally, we have a development partnership with EnBW.
Our focus for open space installations is on developing projects starting from 10 MW, which corresponds to approximately 10 hectares of land. Our main area of activity is in Southern Germany, but we operate nationwide. The projects we develop typically participate in the Federal Network Agency's tenders for EEG compensation. We also develop projects for which a subsidy-free compensation of the produced electricity occurs outside the EEG framework.
The largest subsidy-free project we have developed is also the largest PV project in Baden-Württemberg, the Langenenslingen Solar Park on the Swabian Alb. This project, developed in partnership with EnBW, covers an area of 80 hectares and will have an installed capacity of 80 MW. Construction began on March 4, 2024, as mentioned in the news section.
After successful project development, we construct open space installations as the general contractor (EPC) for our own portfolio and for third-party investors.
New Roof Installations
In 2022, PV roof installations in Southern Germany are doubly profitable. They produce environmentally friendly electricity south of the network bottleneck, exactly where it is needed, and they generate a handsome return for the operator. This is made possible by combining self-consumption with the feed-in of excess electricity for feed-in tariffs. Even roofs not facing south can now profitably accommodate PV installations thanks to advanced module technology and adjusted consumption profiles.
We are happy to analyze your roof area and provide you with a free quote for your PV roof installation starting from 200 kW of installed capacity.
Roof Installation Maintenance
A photovoltaic system produces reliable, environmentally friendly electricity for the public and yields for the investor over decades, provided that the system is correctly configured and built according to applicable standards. Especially in the early years of PV technology, this was not always ensured. A result of deficiencies in planning and construction can be reduced yields, which may cause painful financial losses for the operator over the lifetime of the system.
Regardless, like any technical installation, PV systems must be inspected and maintained at regular intervals. Those who value maintaining their insurance coverage should comply with the relevant requirements.
At least every 4 years, a recurring inspection must be performed according to the standard for Grid-Connected Photovoltaic Systems - Minimum Requirements for System Documentation, Commissioning Tests, and Recurrent Inspections, DIN EN 62446-1 / VDE 0126-23-11. We are pleased to conduct this inspection with highly qualified experts. Common defects found in older installations include:
Errors in system planning and inverter allocation, leading to reduced yields
Missing or incomplete system documentation, causing complications in the event of damage
Dirty modules, leading to reduced yields
Missing or faulty grounding of the PV system, which can lead to severe damage and loss of insurance coverage
We analyze the existing documentation, assess the yield levels of the past years in advance, and inspect the PV system on-site.
Defects are rectified by our experts, and a complete system documentation with a measurement report is created. This prevents yield losses due to defects for the remaining lifespan of the system.
