A well-defined project specification for meteorological sensors is essential for maximizing efficiency and performance of solar energy systems. The Meteorological sensors must be dimensioned to follow the IEC 61724-1:2021 standard and monitored for high accuracy at the Photovoltaic Power Plant (PVPP) level. Each sensor should be integrated with a monitoring system to enable the implementation of meteorological data. The total number of each sensor installed should align with the requirements of Table 2 and Table 3. Two types of solar irradiance sensors should be installed onsite: pyranometers and silicon reference cells, which offer high resilience for monitored data validation. The accuracy of these sensors can be significantly impacted by the sensor type and attachment method, which can lead to significant measurement errors.

Solar Dominates US Energy Capacity Growth
The Federal Energy Regulatory Commission (FERC) has published data showing that solar accounted for over 75% of US electrical generating
