In case the irradiation is the same for each panel:
So,
For example, assuming, Pout = 90 W and, if desired Vout = 90 V then
Voutx = 30V.
Lower irradiation for one panel, for example on panel 2, causes lower output power, so lower
Vout2 due to the Iout constraint:
Output voltage (Vout) required by the load can be supplied by 1
up to the limit imposed by their R3/R4 partitioning.
Some examples can help to understand the various scenarios assuming at the following
conditions: R3/R4 limiting Voutx = 40V and desired Vout = 90V.
Example 1:
Panel 2 has 75% irradiation than panels 1 and 3:
