Solar panel production on a gray cloudy day

Someone asked me yesterday, what kind of production do I make on a day with heavy gray clouds. I told him usually 2 to 10 kWh. Here is the graph for yesterday, 11/18/11.

9/24/11

Solar output graph is the typical day with no clouds and a perfect bell-shaped curve, 20kWh for my 3.7 kW system. Not bad for Fall.

Happy Labor Day!

Yes, another day to rest from work. It is rainy today so the graph tomorrow will be quite interesting. We had monsoons and thunder today. My daughters are back east and their areas, Tennessee and Washington DC, are full of clouds and rain from Hurricane Lee. Here are the graphs for Sept. 3rd and 4th. [...]

3.2 kW

Yes, it is Friday and there were clouds and fog and sun and heat. Look at this graph below and see. Also the highest point of the graph 3.2 was much higher than any of the last month. Go figure. Comments?

My monthly solar output graphs

Here are the monthly solar output graphs for January through July. If you compare Robert’s and mine, one can see that my area had more monsoon clouds than he did. Also one can see the difference in output between 2.9 and 3.7 kW systems. Later we can compare Gordon’s 4.2 system. In the August 2 [...]

Mr. Pip and his solar electric bill

I visited Robert (mr. pip) yesterday and he showed his electric bill to me. He is using less than a 1/3 of the power he used to use and has stayed in tier 1 every month since he went solar, just like me. His bill was $20 or so. He said he had made over [...]

Still on vacation –

Here are the solar panel output results for 7.17.11. If I make 22 or 23 kW everyday that is 660 kWh plus a month.  Cool! [Results from checking on my iPad.]

July 7th solar panel results

Free solar? It seems another month over 600 kWh generated from my free solar panels. Someone told me it can’t be free. And as I have explained here before but for this person the first time, the panels lease which is 60 per month and the electric bill which is now 25 per month, the [...]

Le Tour de France

Every year at this time I am watching the bike race in France for three weeks. It reminds me of summer and our trip to Europe a few years back. France is such a beautiful country it is great seeing it from the bikers point of view along with the helicopter shots. The race is [...]

July 3rd – 92

My dad had a good birthday today, 92 wow! My neighbor got his solar and SCE approval, I think. I will ask him. Maybe he will send over some of his solar graphs to share with everyone with his new 4.2 kW system.
