Consider a solar PV plant with the following specific conditions: Analysis period: 1 year Measured average solar irradiation intensity in 1 year: 150 kWh/m² Generator area of the PV plant: 10 m² Efficiency factor of the PV modules: 15% Electrical energy actually exported by plant to grid: 135 kWh Calculate the performance ratio.
The function of a thermopile is to transfer the heat radiation emitted from the object to a voltage output. The output is in the range of tens or hundreds of millivolts. Thermopiles are used to provide an output in response to temperature as part of a temperature measuring device
