solar panels now are basically the same -
higher watt is Mostly because panel size is Bigger -
1 or 2% higher panel efficiency will be hard to see in output -
build quality can be slightly better - maybe better trace connections -
some panels have better (bigger/thicker ) framing -
from what I have seen - what breaks most often on panels is the Back Flow Diode -
these are easy and cheap to replace if needed -
Cheap solar Charge controllers is what seem to break most often
in systems
buying Good solar charge controller is good investment -
ease of use - easy read - easy adjustment - Safety - this is important -
Ive been using Victron solar charger every day for 7 years -
has worked Flawless -
reacts to clouds instantly -
having solar charger react to clouds Fast is where efficiency gains
can be made -
One pretty expensive brand I have seen takes several minutes after
cloud cover to readjust - this can cause Big losses in output # -
Victron phone app is real Good
Easy to use and adjust - works every time -
Once setup really no need to mess with settings again -
