6 FAQs about [Photovoltaic panel technical performance indicators]
Why do we need a performance guarantee for a large photovoltaic system?
Documentation of the energy yield of a large photovoltaic (PV) system over a substantial period can be useful to measure a performance guarantee, as an assessment of the health of the system, for verification of a performance model to then be applied to a new system, or for a variety of other purposes.
How do you test a photovoltaic system?
The power generation of a photovoltaic (PV) system may be documented by a capacity test [1, 2] that quantifies the power output of the system at set conditions, such as an irradiance of 1000 W/m2, an ambient temperature of 20°C, and a wind speed of 1 m/s. A longer test must be used to verify the system performance under a range of conditions.
Why do large PV systems need analytical monitoring?
Many large PV systems use analytical monitoring to prevent economic losses due to operational problems. As specified by and , the requirements for so-called analytical or detailed monitoring include an automatic dedicated data acquisition system with a minimum set of parameters to be monitored.
Which monitoring data should be included in a PV plant analysis?
For these reasons, monitoring that registers the DC production at least on the junction box level is strongly recommended. The availability of the monitoring data should be 99% or higher. Periods in which either data for irradiance or production is not available, should not be included in the analysis of the PV plant.
How to analyze the profitability and energy yield of a utility scale PV plant?
To analyze the profitability and the energy yield of a utility scale PV plant, the measurement of the generated energy at the revenue meter located at the connection point assigned by the utility would be sufficient.
Are photovoltaic panels reliable?
In 2012, NREL reported long term reliability studies of photovoltaic modules which showed steadily improving degradation rates, with manufacturers offering over 25 years guarantee on their panels . However, very few PV plants have been in existence for such a long period of time, for verification of the guarantee.
