Shading and a wee puzzle for you


Recommended Posts

I have 16 panels 

2 x 8 strings (in series) 

 

On string 2 the first and second panels are severely shaded by a neighbouring chimney for half the day. 

 

The question(s) I have is... 

1. If panel 1&2 is shaded I understand thier performance will be impacted... But will the other six panels be impacted (as they come AFTER the first in second from positive series connection) 

 

2. Can I wire up a series / parallel hybrid... Like the image attached. What would be the best solution to the issue of the two panels being shaded.  What is imoact to volts amps etc in the inverter. 

 

 

There you go a nice wee Sunday puzzle for you ☺ 939258876_panelwiringseriesp.thumb.jpg.fb5f449a4dfb65d89ceea5e31a639863.jpg

If the chimney is a fair distance from the array I doubt it will cause much trouble. But to answer the question we need the Inverter spec. What you are proposing will double the ampage the MPPT will see. That may or may not be an issue.

Tech details are here. But I think you are looking at the max DC input current?

so you have a max 12A imput current on the DC side, your panels run at 10.92 A, so if you configure the wiring the way you want to, you would be trying to input 21.84A - won't like it! :^O
