5-4 Integrated Solar Energy Measurement
The meter can measure the amount of sunlight available at
the installation site of a PV system. The meter can calculate
the total solar energy against elapsed time or calculate the
average solar energy per hour.
The quantity of sunlight reaching a location is effected by
the time of day, the climate (especially the cloud cover,
which scatters the sun’s rays), and the air pollution in the
region.
