A 1.5kW solar photovoltaic system in
is supposed to generate an average of 5.4kWh/day. Does it?
My 1.5kW solar PV system has, as of today, generated 4079kWh of electricity during the 9039 hours it’s been in operation. That’s 4MWh!
I’m a little stupid, so I used this table to figure out that the average day length in
is 12.10785 hours. Then I realised the average day length anywhere on the
planet will be the same over a whole year – that is, 12 hours. That either
means the table, Melbourne, or celestial mechanics are wrong. Possibly all
So, the 9039 hours my PV system has been operating is equivalent to 753.25 days.
If an average 1.5kW PV system is supposed to generate 5.4kWh/day then mine should have generated 4067.55kWh.
Only 11.45kWh off. That’s probably due to the strange error in the solar system, and/or
place in it, identified earlier.
