Does a solar panel receive as much energy on a hot sunny day than on a cold sunny day?

Hi, solar engineer here.   In short, no. Temperature does not affect the solar insolation received on an array.  However, higher temperatures decrease the voltage and efficiency of PV cells, so when it is hot they typically produce less energy.

When it's cold they actually produce more, but in most places colder weather corresponds with less direct solar radiation.

When designing a PV system, designers have to take into account the highest and lowest temperatures an area will experience to make sure the array will fall within the voltage window of the inverter.
