how can i calculate the Kwp, for PV solar panels?
April 24th, 2010 | by admin |not the water ones the electricity, its for auni project im using a energy asssesment programme and i have potential 10m2 of solar panels. however theprogramme asks for the Kwp?
The supplier should tell you.
kWp =
Area * efficiency of the panel AS A FRACTION (so 15% efficient = 0.15)
This is pretty simple because efficiency is calculated for a spectrum of light with 1kW per metre squared intensity. The real equation is kWp = Area in m^2 * assumed intensity of 1 kW m^-2 * efficiency.
You could also calculate it if you know the maximum current out and voltage from P=IV.
If you can’t find any info for your panels, you can try looking at panels on the internet and seeing what they give you in kWp/m^2.

It should be listed on the panel or in the Owners Manual.

That would be your peak kilowatts produced, which is entirely dependent on the specific panels your using. For 10 square meters, maybe 3kW (12volts x 250amps) at the most.
