Searching for opinions.....is this "over design"?
Designing small system (2.35kW). Customer uses gas for heating. Typical A/C
unit. I was thinking of biasing the tilt to summer production for greater
offset of summer demand (lat 31.6, proposing 18). No net metering in this part
of the world. PVwatts shows a drop of 2% /yr. in production , 5% higher
production for A/C months. Feedback?
Also, this array will go on a carport. I understand that windloading is
actually greater for an open structure than one with walls (another reason for
lower tilt) - is there any one that can direct me to data on finding out how
much more?
Lastly, what is a good avg. target derate factor for Enphase inverters (real
world)?
