Solar Technologies

Grünkraft is one stop shop offering 360 degree services from the conceprion of the project up to the construction and operation and maintenance. Our commitment on 6 sigma methodology improves project efficiency, quality, and safety by using statistical analysis to reduce defects and variability in processes like design, installation, and resource management ultimately leading to cost savings and higher customer satisfaction.

Up to date we have successfully developed (greenfield) 604 MW of solar projects and 100 MW of Storage projects out of which 304 MW of Solar reached Ready to Build status, while we have constructed as of 2011 to date more than 650 MW of solar projects.

We are offering all the services for the Project Development, Turnkey construction, Operation & Maintenance

PV Turn Key Construction

With own machinery, equipment and personnel Grünkraft is a self-performing contractor, bringing in-house construction team and equipment to offer solar construction services from A to Z, as of Landmarking, Fencing and Groundworks up to Mechanical and Electrical installation.

By applyting the principles of 6 sigma methodology (Define, Measure, Analyze, Improve, Control) we quantify problems, identify root causes, implement solutions, and ensure long-term consistency, ultimately leading to cost savings and higher customer satisfaction.

Our main principles in excuting a PV solar construction projects that lead to Higher R.O.I. for the end customer are:

Design Optimization:

Resource Optimization:

Process Streamlining:

The works begin with the landscaping of the site, Ground remediation which it may includes excavation, water drainaging, internal and external access roads, drilling and then we proceed to fencing and the opening of trenches for the placement of probes and cables. Next we install the appropriate equipment, which includes the PV modules, the inverters, the mounting systems, the electrical panel, the switchgears, the AC & DC cablings, the lightning protection and the ground earthing systems

Solar Shading Analysis & Optimisation

Grünkraft supports, evaluates and takes all the necessary steps for the completion of the Solar PV project as from the early stage of development (green field Project Development) up to the connection.

BESS EPC Services

Grünkraft acts as a BESS project developer and EPC contractor and whether acting as a full EPC partner, or BOS partner or subcontractor, delivers optimized designs, scalable solutions on Storage Projects.

Operation & Maintenance

Grass cutting and PV pannel washing

PV Panel washing: with specialized cleaning equipment, we ensure that panels are free from debris, bird droppings, and other obstructions, optimizing their effectiveness.
Grass Cutting/ Vegetation management, with specilized equipment we cut the grasses all around the plot and beneath the PV arrays to prevent shading, ensure access to equipment, and reduce fire hazards. Grass cutting in solar farms provides optimal site yield and a longer panel lifespan by keeping panels and cables clear of obstructions and tarnish.

On site Inspection & Maintenance

Detailed visual inspection: Systematic examinations for damages such as panel cracks, discolored cells, and broken glass.
Electrical checks: with diagnostic tools we detect corroded terminals, assess loose connections, and monitor any potential damage to cables or connectors.
Inverter health checks: detailed inverter logs and software diagnostics to catch potential issues early.
Alignment optimization: Measuring panels are at the ideal tilt and orientation, taking into account local solar angles and potential shading.
Ventilation assessment: Ensure cooling systems are efficient, especially for inverters, to avoid overheating and potential system failures.
Safety protocols: Regularly test all safety devices, including ground fault protection systems and disconnect mechanisms. This not only ensures system safety but also complies with regional and national standards.
Substation cleaning and maintennace

PID Ascertaining & Measurements

Potential Induced Degradation (PID) is an undesirable property of some solar modules. The factors that enable PID (voltage, heat and humidity) exist on all photovoltaic (PV) systems, but the effect does not occur on all or even most PV systems.Grunkraft is specialized in PID effect diagnosis with a unique method which goes one step further than the usual IR photos. IV Curves, Reverse current and Electroluminesence are used to ascertain the existance and degree of the PID effect.
