The solar panels should theoretically put out about 3800 watts maximum when the sun is overhead and there is no shading. Unfortunately there are 2 trees that shade them until the sun reaches about 35 degrees in the sky, so we have not had a full days production yet. The maximum instantaneous power we have gotten so far has been about 2400 watts, because just as the sun is getting highest in the sky ( 24 degrees! ), the trees start to shade them.
We actually hit max production for the day a little before 10:30AM and then again after about 2pm – so what should be the best time of day is blocked out.
This chart shows how high the sun gets in the sky across the year.
We have to wait until mid march before we will have a day of full sun with no shading. Do we cut down the trees? Only time will tell.
It also shows that the maximum possible number of sun hours ( where the sun is at least 15 degrees above the horizon ) in february is about 6, and in june it will be close to 12. In march we will have about 6 hours of the sun above 30 degrees and in june it will be about 9 hours.
As you can see we have only had 3 or 4 days so far with minimal clouds.
Every day as the sun gets higher the best day will improve.
I am hoping that by june most days are sunny and those sunny days will produce 30+ kWh.
More to come.
