Parallel Solar Panels

I have been learning that parallel strings in a battery bank are not the best way to go.
My questions here is does this apply to solar arrays as well?
I have Renogy 250 watt 24 volt Poly.
I am thinking of
3 panels in series and 5 parallel strings for a total of 15 panels (3,750 watts)

Solar panels work great on parallel. They are "current sources" which naturally share current very well (assuming a properly designed and constructed array).
Also, with 3 or more parallel strings, you need a fuse/breaker per string for safety.

I don't know why Renology identifies their 250W panels as 24V--it is misleading and confusing. A true 24V panel would be able to charge a 24V battery bank. The Renology panel has a Vmp of 30.2V which is insufficient for an equalization charge on a 24V battery.
This is just an observation and has nothing to do with the original question. Your panels will work fine in series strings of three.
