The voltage measured at the inverter is the inverter determined voltage, not
necessaryly Vmp-Vdrop The inverter can select the operating Vmp correctly or
incorrectly, the shading or module mismatch will have a great effect on this
voltage. I have always found the measured to be below the
Phil,
What measurements do you get for:
Location
Date
Time
Weather (clear, hazy, cloudy, partly cloudy)
Irradiance
Ambient Temperature
System DC STC Power
Cell Temperature
DC Voltage (at what point?)
AC Power

Great article on performance calculations in the previous issue of Solar
Pro, pp24.
I made a quick & dirty spreadsheet that we use to plug in measured values on
site to give us a ballpark during checkups.

Wrenches,
I was looking at some of our web-based monitored systems this morning to
check in on some performance numbers, and this question came up.
I can see a measured DC array voltage on-line (as measured at the inverter),
and I have cell temp information so I can calculate the theoretical
temp
I have a client that wants all black hardware including the roof boots.
Has anyone used the black Thermoplastic Oatey boots with 3" standoffs?
Thanks,
Nik

Hi Wrenches,
I am not sure what the policy is for advertising on the list, but I
feel sure that some of you will be interested to hear that I will be
coming over to the USA next month to teach a couple of workshops in
Washington State.
Saturday, April 6 --11 I will be helping Roy Butler with
6 matches
