Re: 13 panel string putting out just over 200% of what 4 of the same panels put out.
Three bad panels sound about right... You could lose upwards of 30-40 volts per "dead" panel... Your present Vmp-array is something like 100-120 VDC "less" than I would have expec…1 · -

Re: Panels no giving full power 2700 watts
Guessing that JHB is Johannesburg, South Africa... Without knowing anything about your system, I would expect the maximum output on a warm/clear/around solar noon day, that your array would max out a…1 · -
Re: connection without battery
Find a solar panel with Imp roughly 2-3x (at least) the rated current of the fan (I.e., a 24 volt fan @ 0.8 amps would be a solar panel with, roughly, 1.6 amps or greater Imp rating). A "typical…1 · -
