Sunmeter pro bifacial irradiance sensor is a combination of two digital photovoltaic pyranometers (or silicon irradiance sensors) for calculating bifacial photovoltaic plant performance with a high degree of precision and reliability.
The sensor simply consists of two Sunmeter Pro photovoltaic pyranometers in which the upward facing pyranometer measures the incoming global solar radiation and the downward facing pyranometer measures the reflected global solar radiation.
This bifacial irradiance sensor helps in measuring the performance of the bifacial PV module’s as well as helps in the calculation of the solar albedo. Solar albedo which is the ratio of the reflected radiation to the global radiation. It mainly depends on the properties of the surface and the directional distribution of the incoming solar radiation.
