Measuring and estimating the temperature of photovoltaic modules
1. Introduction. Module temperature is an important factor that influences the power produced by a photovoltaic system (Ye et al., 2013, Lobera and Valkealahti, 2013).Typically, a crystalline silicon module loses about 4% of its power output for every 10 °C raise in module temperature.Since module temperatures above 45–50 °C are usual …

Linearity. The linearity of the short-circuit current (I sc) with total irradiance is an important measurement for reference cells because the standards require the reference cell to be linear over its range of operation.NREL measures the linearity of I sc in the range of 0 to 2 suns using two lamps and neutral-density filters.
Guidelines for accurate current
that the two methods are equivalent as the cell is already under "high" injection when the irradiance is increased from the 0 to 200 W/m 2 on the rear side.

SunsVoc
SunsV OC measurements 1 2 are very similar to the J SC V OC measurements except that the SunsV OC uses a separate solar cell to monitor the illumination intensity rather than using the J SC of the solar cell. The monitor cell simplifies the measurement electronics since measuring cell voltage is much simpler than measuring the cell current.
