SPV1040 parallel and series connection
20/24
Poutx
According to the light irradiation on each panel and to the system efficiency (η), the output
power results:
Therefore:
Each SPV1040 contributes to the output power providing Ioutx.
Finally, the desired Vout is guaranteed if at least one of the 3 PV panels provides enough
power to turn on the SPV1040 relating to it.
SPV1040 series connection
This topology provides an output voltage that is the sum of the output voltages of the
SPV1040 connected in series. The objective of this section is to explain how the output
power is impacted by the selected topology.
