Im in a start of building a PV field with two Deye 6k Inverters and didnt brought anything, im in Europe Ukraine, sun is expected to shine 4-5 month on good basis, all other is very shady weather.
We have only Risen and Longi solar panels on market
Attached inverter specs-and solar panel specs) inverter and panel are last coloums
What and how would you advise me to build the solar field efficiently on which trackers?
Solar panels would be placed on a flat roof with a 25% angle in album mode (longest side parallel to the ground)
i was looking at a solar panel Longi Solar 540 W LR5-72HPH Mono PERC
which has 12.907A (inverter maximum is 13Amps) so this suits me. i dont think those PV amps ever happen in my angle and summer heat but i dont want anything to break.
I was thinking of connecting
MPPT 1 with 8 panels i get max 336V with 400v Voc (4320 W)
MPPT2 with 6 panels i get 252V with 300v Voc (3240W)
Which totals 7560W which is lower than 7800 inverter capable of
With our weather i expect those numbers to be 20-50% less during summer time (rains, clouds, city fog)
Can you critisize my choice please?
Should i choose any other panel, or change number of panels per MPPT, or other advices?
