# Does the load at where Pmp of a solar panel is oberved change with temperature?

After reading up on solar panels, I know that the max power that a Solar panel can supply ($$\P_{mp}\$$) will drop as the temperature increases. The $$\V_{oc}\$$ will decrease a lot more than $$\I_{sc}\$$ increases, so the Fill Factor will go down.

But this is the one thing I haven't been able to find an answer to. Say, $$\P_{mp}\$$ of a solar panel that has a temperature of 25 °C is observed at a load of 20 KΩ. Will the load where the solar panel has its $$\P_{mp}\$$ change at a different temperature, and if so, will it increase or decrease?

• As a general rule, maximum power output is when the load impedance is the same as the internal impedance. – Janka Jun 1 '19 at 1:17
