PV and BESS assessments

We can support the success of your project with the following reports.

BESS revenue assessments

Our BESS revenue assessments enable project-specific modeling of battery storage systems, accounting for their technical and economic characteristics and intended marketing strategies. They thus offer a well-founded outlook on potential marketing channels and the resulting revenue potential to assess the investment's profitability under the project-specific conditions. The storage system can be considered either gray or green electricity storage and can be designed as a stand-alone solution or in a co-location configuration with PV systems, wind turbines, and/or electricity consumers. In addition, various marketing options can be simulated to assess revenue stacking.

The calculation can be based either on historical price data (backtesting) or electricity price forecasts (forecasting). 

Valuation reports and mortgage valuation reports

A valuation report for photovoltaic systems determines the current market value of a system, taking into account factors such as age, technical condition, system technology, and maintenance. It provides an objective basis for financial, legal, and insurance decisions, especially in sales, contract terminations, claims, and refinancing. By assessing wear and tear, performance levels, and economic potential, it provides investors, operators, insurance companies, and credit institutions with a reliable basis for realistically estimating the system's value and preparing for the future.

Based on a valuation report, we can also prepare dedicated mortgage valuation reports.

Damage assessment

A damage assessment for photovoltaic systems documents and evaluates damage caused by storms, hail, fire, vandalism, or technical defects; identifies the cause of the damage; assesses the extent of the damage; and estimates repair costs. It also accounts for possible yield-related reductions, ensuring that both immediate costs and economic consequences are presented transparently. The report serves as a basis for insurance, warranty, or legal claims and enables fast, comprehensible claims settlement.

Demolition  report

A demolition report for photovoltaic systems and battery storage provides a sound basis for planning, evaluating, and carrying out decommissioning, including technical processes, legal requirements, and economic aspects. It assesses the condition of the system, identifies risks, and determines the expected dismantling and disposal costs, taking into account possible proceeds from resale or recycling. The report thus provides clarity for operators, investors, project developers, and authorities, supports the realistic calculation of dismantling processes, the measurement of provisions, and the orderly termination of projects.

Document review

The document review ensures that your PV system has been fully implemented and complies with the standards. We review all relevant planning documents, certificates, expert reports, and commissioning reports, and check compliance with legal and technical requirements.

Repowering

A repowering assessment evaluates whether replacing, modernizing, or retrofitting existing PV systems makes economic and technical sense by analyzing the system's current condition, actual yield data, and the potential of modern technologies. It identifies weak points, simulates optimization measures such as replacing modules, inverters, or cabling, and accounts for investment costs and regulatory requirements. The aim is to provide operators and investors with a sound basis for decision-making to tap new economic potential from existing systems, especially after the expiry of feet-in tariffs or when site contracts are extended.

Glare assessment

A glare assessment examines the potential glare effects and light emissions of photovoltaic systems that could be disruptive or dangerous for residential areas, roads, railway tracks, or air traffic. It assesses local conditions using modern simulations and, if necessary, on-site inspections to check whether the system complies with the legal requirements of the Federal Immission Control Act (BImSchG). The aim is to identify potential glare effects at an early stage, optimize the system's orientation and positioning, and avoid conflicts with affected stakeholders or authorities, thereby supporting the approval planning process.

Noise prediction

Noise prediction evaluates the noise emissions of photovoltaic and battery storage systems and their components, such as inverters, transformers, or air conditioning systems, to ensure compliance with legal noise protection requirements (e.g., TA-Lärm). It includes forecasts in the planning phase and considers emission sources, sound propagation, and protective measures. The aim is to identify potential conflicts with residents at an early stage, minimize disturbances, and ensure the system's acceptance and trouble-free operation, often as part of the approval documentation.
