+Partial shade in good sun can have a drastic effect on panel output.  This is because panels are made of strings of individual solar cells;  having some strings turned "on" and some "off" (to prevent reversing current //into// the shaded cells) can result in dramatic power reduction.
-This effect can be attenuated somewhat by panel design (bypass diodes), parallel rather than serial panel connections, use of amorphous panels, and the use of MPPT controllers.
+This effect can be attenuated somewhat by panel design (bypass diodes), [[electrical:solar:series_vs_parallel|parallel rather than serial panel connections]] when using PWM controllers, use of amorphous (thin-film) panels, and the use serial rather than parallel panel connections of MPPT controllers.
