So:
Each SPV1020 will contribute to the output power providing Ioutx according to the irradiation
of its panel.
Also, desired Vout will be guaranteed if at least one of the 3 PV panels provides enough
power to turn on the related SPV1020.
SPV1020 series connection
This topology provides an output voltage that is the sum of the output voltages of the
SPV1020 connected in series. Following pages explain how the output power is impacted by
the topologic constraint.
Following figure shows a detail of the series connection topology:
