I have the 1270W of PV to allow for overcast days, but my Controller is only good for 650W. As a consequence, my efficiency is well down as I never attain 1270W of generation.
Also all energy generated is self-consumption or battery stored. So again generation depends on demand. maybe a setting to flag self-consumption, and use energy consumed to calc generation.
Other than that, brilliant site, and very much appreciated.
