FAQ
Frequently asked questions — answered briefly.
Technical audit, risk assessment, project security: Here you will find concise answers to the most important questions about our services.
What services does 8.2 offer for hydrogen projects?
We support the entire H₂ value chain — from feasibility studies and safety assessments to integration with wind, PV and storage systems.
What is a compliance check after a plant has been put into operation?
It confirms that the plant was implemented as planned and meets all requirements of the plant certificate. Only then is legally compliant operation possible.
When does a technical inspection of a battery storage system make sense?
Before acceptance, as part of innovation tenders or when changing operators. Tests document construction quality, compliance with standards and residual defects.
What is checked during a due diligence for battery storage systems?
Technical risks such as contract gaps, quality deficiencies, safety concepts or location issues — from approval to commissioning or existing projects.
Why should I have PV modules independently tested?
Because international supply chains pose risks. With factory audits, production monitoring and tests, we ensure that modules comply with standards and work reliably over the long term.
How does a thermography inspection work for photovoltaic systems?
With infrared cameras, hotspots and defects are visible that are not visible during normal operation. In this way, yield losses can be avoided and maintenance can be planned in a targeted manner.
What is a yield report for photovoltaic systems?
A yield report predicts the realistic energy yield of a PV system and is the basis for financing, planning and investments.
What are the advantages of a rotor blade inspection with drone or cable access?
Both methods allow rapid, precise damage recording with minimal downtime: drones provide an overview, cable access provides detailed analysis.
What is a continued operation report (BPW) for wind turbines?
At the end of the planned useful life, a BPW checks whether and for how long a plant can continue to be operated technically — legally secure and economically sound.
Why are recurring tests necessary for wind turbines?
Because they ensure stability, prevent damage, extend lifespan and meet legal and insurance requirements.
Which technologies does 8.2 test and evaluate?
We support projects in wind energy (onshore & offshore), photovoltaics, battery storage, grid integration & certification, condition monitoring, HSE/digital occupational safety and green hydrogen.
Why should I have my energy projects checked by 8.2?
8.2 works independently of manufacturers, neutrally and in accordance with recognized standards. With over 30 years of experience and international presence, we secure investments, minimize risks and create a reliable basis for decision-making.
