Hi.
Would like to implement an analog 'passive' meter for solar irradiance to know how sunny is outside. Do I need to know the wavelenght band the solar panels are ?
Setting scale 100% (power) at 1KW/m2; 75% being 750 W/m2; 25% being 250 W/m2
As measurement is for Watts, what considerations should be taken to drive a D'Arsonval meter ?
