 ===== TL;DR =====
-  * With [[electrical:solar:charge_controller#mppt|MPPT]] solar charge controllers and a 12v house battery bank there is often little practical difference between parallel and series setups.
+  * With [[electrical:solar:charge_controller#mppt|MPPT]] solar charge controllers and 12v house battery bank there is often //little practical difference between parallel and series solar arrays//.
-  * [[electrical:solar:charge_controller#pwm|PWM controllers]] run arrays of the same nominal voltage as their battery bank:  12v and 12v, 24v and 24v.  A 24v array could be made of 24v panels in parallel or 12v panels in series.((2S))
+  * [[electrical:solar:charge_controller#pwm|PWM controllers]] run arrays of the same nominal voltage as their battery bank:  12v and 12v, 24v and 24v.
-  * series arrays can reduce costs in some circumstances
+  * //generally speaking//, parallel panels will perform better in [[electrical:solar:shading|partial shade]] than series. [but don't shade your panels in the first place -- secessus]
+  * as with other [[electrical:12v:parallel_serial|series/parallel arrangements]], series increases voltage and parallel increases current.
+  * series arrays can reduce capital costs in some circumstances
+  * series/parallel arrangements are described with ''xPxS'' nomenclature:
+    * 2 panels in parallel would be 2P1S
+    * 2 panels in series would be 1P2S
+    * 4 panels in series-parallel would be 2P2S
