We support owners and investors in ensuring projects are viable and contractually sound. In cooperation with the German Solar Energy Society DGS we offer Energy Audits and Technical Due Diligence for Photovoltaic Power Plants.
Energy Audit - PV Yield Studies
The energy audit includes a technical and economic assessment of a photovoltaic (PV) power plant. Independent Energy Audits are often the pre-condition to providing a loan by the bank.
The basis for maxx-DGS Energy audits are location-specific reference weather data sets determined from several meteorological data sources and the planning documents provided by the client. The feasibility of the project will be analysed by evaluating the design with at least 2 different simulation tools considering shading, mounting situation, system design and system losses like module mismatching and efficiencies of the technical parts. The results will be evaluated and individually corrected professionally to determine the estimated electricity production and performance ratio. This precise monthly forecast will be documented, together with the detailed calculation, in an independent report.
Technical Due Diligence
To ensure that your solar power plant is working as intended or if you want to check if everything works to your satisfaction, the maxx-academy offers an independent technical photovoltaic project analysis according to the PV system quality assurance standards RAL-GZ 966:
- Examination of the construction acc. to RAL-GZ 966 by an on-site visit
- Check of plant components acc. to RAL-GZ 966 by an on-site visit
- Inventory of deficiencies acc. to RAL-GZ 966
- Formulation of rework demands if applicable
- Detailed reporting acc. to RAL-GZ 966
The realisation occurs under the direction of Dr. Matthias Klauss, maxx-solar academy master trainer and president of the RAL Gütegemeinschaft Solarenergieanlagen e.V. (RAL Solar Plants Quality Assurance assocciation).
The Due Diligence reports and Energy Audits are issued jointly by the DGS and the maxx-solar energy PTY Ltd. The German Solar Energy Society DGS society was founded in 1975 and is the oldest consumer protection society in the field of renewable energy technology and rational energy use in Germany. The technical inspections and Energy Autits performed by DGS have a very high standard and are recognized by banks and assurance insurers as basis for investment and payment decisions.
