I have an off-grid system that I’m upgrading with more PV but since I’m going with an MPPT I need to replace all, superseded, panels. In the above article you’ve mentioned mono outperform poly in low light. My question is “by how much”? We are in a sub-tropical area that at certain times of the year can have many consecutive cloudy days and I’m trying to get an idea if it’s worth spending the extra $ on mono….?
Roof space is not an issue, nor is the temperature coefficient.
Other specs, if relevant, are currently 10xKC80, 24V as 12x2V AGM. PL40 being upgraded to a 60A MPPT.
Thanks for your help.
