Appendix B
Output pins of SPV1020s can be connected both in parallel and in series. In both cases the
output power (Pout) will depend on light irradiation of each panel (Pin), application efficiency
and by the specific constraint of the selected topology.
Objective of this section is to explain how output power is impacted by the selected topology.
Examples with 3 PV panels only will be presented, but conclusion can be extended to a
larger number of PV panels.
In case the SPV1020 is on (so light irradiation implying Vin = 6.5V)
In case SPV1020 is off, the system efficiency will depend on the drop of the bypass diode
D1 (according to schematic in
Finally, in case of panel completely shaded:
