Oh , thats good performance , the 50 degrees i supose have something to do with that too , so in your case its probably 1/3 or 1/4 of your electricity needs (just assuming) , in my opinion there needs to be concepts to go way over 4 kW PV if land or roof allows Happy new year , let the sun shine ,let... |

Hi Billi
The 50 degree angle certainly helps as my other 10.24kWp system (at about 15 degrees) often struggles to match the output from the 3.87kWp at this time of year. The December total of 83.6kWh is only just above the December average from the past ten years of 82kWh (low of 58kWh and high of 115kWh).
Looking forward to the sun being higher in the sky from now on.
