Planning and Design of Photovoltaic Power Plants
The design of the PV plant according to all relevant standards and regulations will make sure that the plant will work safely and reliably with risks of failure or damage reduced as far as economically viable. The use of the latest design software will guarantee effective yet cost-efficient component selection.
- detailed drawings (module mounting, electrical single line AC and DC)
- selection of main components such as PV panels and inverters
- low-loss yet cost-efficient selection of electrical components such as circuit breakers, transformers, switches and cables
- deisgn of special PV systems such as off-grid, diesel-hybrid or DC generators
Yield SurveysThe yield survey gives the investor confidence that a specific yield or performance ratio (PR) will be achieved by the PV-plant, thus reducing the technical risk of his investment.

Technical Due Diligence
All technical documentation needs to be checked and verified (e.g. before procuring a PV plant). This will guarantee that all relevant drawings, datasheets, calcucations and documents are available and according to the relevant standards and regulations. The technical due diligence shows failures or shortcomings in documents or the PV installation before they become an issue.
- verification of drawings and documentation according to relevant standards
- verification of component selection and cable diameters
- electrical verification & testing (BS EN 62446)
- PV-performance considerations
- PV-curve meausrements
- Inspection with infrared camera
Submission planning of photovoltaic projectsFor the submission planning of a PV installation special care is taken of a detailed documentation that allows the relevant authorities to issue a building permit for the PV-plant without the need for later changes or amendments. This includes the design of all plans, drawings and documents as well as the submission of all necessary requests and applications (zoning, grid connection, building permit, incentive scheme)

Construction of PV power-plants
We develop and plan PV power-plants and support the construction of large PV-plants as site supervisor or project manager. Site management, site logistics, incoming goods acceptance, claims management, instruction and supervision of personnel and subcontractors, verification and commissioning is executed to clients' complete satisfaction. A smooth organization of the construction site allows faster, cost-effective construction with avoidance of errors.
We build our PV plants with high quality European components and are able to provide all works including start-up and acceptance tests as a seamless turnkey project. All our plants are planned and constructed according to European norms and regulations. A complete plant documentation, CE-certification and maintenance manual is included with all our installations.
Operation and Maintenance of PV power-plants
We verify, monitor and maintain PV power-plants. Our broad spectrum of services allows cost-efficient and fast completion of all works. Performance measurement, visual inspection, verification and exchange of inverters and PV-panels, performance optimization, verification of electrical safety, earthing measurement, infrared measurement of PV panels and electrical panels, verification of lightning protection equipment, insurance survey report, management of warranty claims.
