Gantner - Model 116 - PV Plant Monitoring String Blox
From Photovoltaic String Monitoring
Effective PV Monitoring requires constant, solid and traceable PV Plant monitoring data in order to determine actual performance and fulfil owner/investor expectations. Operators are interested to identify errors and losses in a reliable way to trigger appropriate actions for maximizing energy harvest during the total system lifetime. With the monitoring of PV Module strings, design and production errors will be recognized on the DC side with high resolution down to PV Module level.
