Solar output graphs – Year to Year comparison

February 10, 2013

Here is the graph of yearly output for 2010, 2011, and 2012. In 2011, my first full year, the total output was 6499 and in 2012 the total was 6404, which means 95 less kWh from the first full year to second. That could be because of the weather, dirt on the panels, age of […]

June 2012 results compared to June 2011, yearly results and day results

July 4, 2012

Well, I am not making as much this last June as I did a year ago. Maybe due to more foggy mornings, tree limbs or dirt on the panels. I will have to wash them off one early morning. They are looking pretty brown and dusty. My neighbor’s panels look similar to mine and could […]

January 8th data – solar

January 9, 2011

Cloudy all day of course, eight days only 72 kWh. That means maybe 270 or so at the end of the month. We will see. It depends on the sun of course and the clouds. Have a good January.

Merry Christmas and sunshine in California all day

December 25, 2010

Yes, it was sunny all day yesterday, just as all the company was gone, we had sun all day. December 24th was beautiful! The snow on the mountains is so pretty today. It let the ground dry up and things are getting back to normal around here. Here is the graph of December 24th to […]

Nov. 30th graph – afternoon trees still shading the solar panels

December 1, 2010

Oh, yes I am back from Tennessee and happy checking my solar panel inverter graphs again! Here is the graph for 11/30/10. The graph shows the afternoon shading starting at 1:00 pm and continuing for several hours after that. If I had to do it again, I would move the lowest 3 panels up to […]

Mittens changed to mountains.

November 17, 2010

Here are the graphs from yesterday and now half way through November my generation total is 277.4 kWh. So maybe at November 30th, I will have 540 kWh, not bad.

My solar panels wear mittens?

November 16, 2010

Today’s graph looks like winter mittens. Yes, mystery solved. During the 1:15 – 2:15 p.m time, my large pine tree in back that had never shaded the panels before is now shading during that hour. Also, after 4 p.m. the older Aleppo Pine shades the solar panels due to the sun so low on the […]

Trees and solar panels 2

November 13, 2010

As I said I would, I took some photos of the solar with the tree shading on it. I called my Sungevity representative, Justin Cox about it yesterday. He said that their primary concern is there is no shading between 9 and 3 or 10 and 4. Since my shading is from 7:15 to 8:15 […]
