Verify the real performance and availability levels of your PV power plant
Following the construction of a photovoltaic (PV) power plant, engineering, procurement and construction (EPC) contractors must ensure that the installation meets performance and availability levels stipulated in the contract. Owners and operators need accurate and trustworthy information about the plant's performance to set cash flow models and maximise performance/financial yield. This information ensures the plant meets or exceeds its potential and that the maintenance company they work with delivers on quality commitments.
Stakeholders must also avoid the possibility of inaccurate data from meteorological sensors due to incorrect placement, inclined position, lack of calibration, high uncertainty or inappropriate sampling interval. This is important because inaccurate data can make a PV power plant appear to have a good performance ratio even when it operates poorly.
TÜV SÜD’s experts carry out direct and independent calculations to analyse the production of PV power plants. We also help to assess the meteorological data and geographical conditions of your PV power plant location.
Performance ratio assessment
TÜV SÜD compares simulated production and the value measured on the plant's electrometer. Ideally, both values should match.
Based on this comparison, we can determine if the PV power plant performs according to expectations or if the monitoring system is not working correctly.
Our experts perform a site assessment that includes measuring solar access, evaluating influence from surroundings, identifying pollution sources and assessing soil suitability.
Energy yield assessment
TÜV SÜD offers abridged expert assessment using standard PV components and system-related energy yield reduction factors.
Our detailed expert assessment covers investment decisions and bankability.
We provide a review of the energy yield from existing PV plants as well as root cause analyses in case of reduced energy yields.
Invest with confidence – by obtaining a realistic assessment of your PV power plants' real production value and production efficiency to maximise the predictability of returns on investment.
Save money and ensure reliability – by identifying problems in your PV power plant to avoid future energy / financial losses.
