advanced graph -Solar KWH
« on: March 11, 2018, 01:42:35 PM »
Just a quick question,
Are the measured KWH figures measured as per m2 of solar panel?

This is a very relevant graph and figures for me currently as i will be buying solar towards the end of this year  and i'm using figures from my WD and raw solar data to assess what size system i want.

That's solar radiation per meter2 x Time. To convert that to what a m2 solar panel would generate you need to multiply by the efficiency of the solar panel and the efficiency of the inverter. Also your Davis (I assume) sensor is horizontal, whereas the panels will be at an angle optimized for your location.

That's a lot clearer, cheers.
It gives me a much clearer picture.
