Zombie Posted June 15, 2023 Share Posted June 15, 2023 I understand that the colder the panels are, the greater the volts they produce. Does that mean the inverse for amps is true due to P=V*I; so the warmer it is the more amps are generated? Cause the power stays constant right?

Coulomb Posted June 15, 2023 Share Posted June 15, 2023 (edited) In fact panel current does increase slightly with temperature, but not as fast as voltage decreases. So both voltage and power have negative temperature coefficients, but the power coefficient is lower in absolute terms (closer to zero). The temperature coefficient for panel current is positive. These coefficients are all for silicon panels (mono or poly crystalline), which is virtually all panels at present, apart from a handful of flexible panels. This could change if exotic chemistry panels become popular. Edited June 15, 2023 by Coulomb Quote Link to comment Share on other sites More sharing options...
