GerhardvN reacted to hoohloc in Growatt reviewsBecause you have mixed the 360w and the 335w, you need to use the lesser one when doing your calculations. i.e 12 x 335w which gives you 4020w total at 100% efficiency. now, check the spec of your panels to see their efficiency and deduct that from your total. Assuming that they are 80% efficient, you get 3216w as your total. Now, factor the other stuff like tilt angle and azimuth etc
This is just a rough estimation
