This thread started out about 95% PWM. I believe 95% or 90% or ever 85% is not the real problem.
If you short out a solar panels you get 0 volts and maximum current.
0 voltage X max current = 0 watts
If the current is 0 then the voltage is maximum.
Max Voltage X 0 current = 0 watts
There is a sweet spot where watts = maximum and voltage = ? and current = ?
Solar power supplies I have designed are constantly looking for the sweet spot. If a cloud or maybe a bird goes overhead the duty cycle changes to get maximum power out.
I know “%” is important. If you don’t know how to get the most out of you panel under all conditions you are likely not using 30% to 50% of the available power.
