Solar expansion - mixed panels

Solar expansion - mixed panels

Had 3 x 305W's and added 3 x 330W's in January 2019 and decided to only add another 2, ended up with adding 5 x 350W's. 305W's are 4 years old and not 100% efficient anymore, thus I connected the panels in the following way:

3 x 305W's in series

2 x 330W's in series

1 x 330W & 350W in series

2 sets of 2 x 350W's in series and all in parallel.

With 10% loss on 305W's my calculations work out that I only have a 8% loss on complete configuration as result of mixing and matching. 

Increased power from 1.8kW to 3.2kW
