Hi,
3 panels in series. A bird dumps on one panel and output drops by 50%. Not just for the one panel, but for all three.
Best to find panels that are high voltage and wire in parallel.
Incorrect. The bird dropping activates the bypass diode in one panel section ie you lose 1/3 of the power from that single panel. Or you lose 1/9 of the power from all 3 panels with 3 bypass diodes in each panel. To be clear the amps don't change and the voltage is now 8/9 or 89% of the total.
For parallel that panels voltage drops and it no longer contributes so you are at 67% of the power.
