Simulation of the temperature of photovoltaic modules

[FGsilentd]

When I was conducting an off - grid simulation of photovoltaic power generation, in the simulation results, when the light intensity did not reach the threshold, the average operating temperature of the photovoltaic modules was 0 degrees Celsius. However, this is unreasonable. At this time, the temperature of the photovoltaic modules should be the ambient temperature. How should I handle this situation?

Hello,

Indeed, if there is no production, the temperature of the modules are simply not calculated and put to 0. This has no impact of the result of the PV production since no thermal inertia is considered for the hourly simulations. For a more elegant output file we will considered changing this approach. For your evaluation you could consider the 0 as null and exclude from your average, or replace them with for instance the ambient temperature. 

Thank you for your input.
