Electricity usage trend - 4 years

Posted on June 12, 2012 at 3:37pm 1 Comment

I have been working on reducing my consumption for about 2 years now and in the last year have added solar to the mix. Below you will see the usage trends for my PG&E electric bill. Starting with the most recent and I highlight the highest month of that year.

From a high in Jun-July2009 of 1252kwh to a high in Jun-July2011 of 855 kwh. That's a reduction of 397 kwh. (Update) New lowest usage was the last bill May-June…


Solar n00b - my experience with solar - PG&E bill Update

How it Started:

I started down the solar road looking for a way to have power while camping. I didn't want to use a generator due to noise so I began looking at various portable solar projects out there. There where lots of already packaged systems some small others more ambitious but they all had a high cost. I also didn't know a lot about solar itself other than the obvious 'sun shines on us during the day". I began reading blogs, doing searches and collecting links that held my…

Mr. Ray

Bill from the woods of Minnesota here. I looked at a few of your graphs, looks like your doing well. I'm basically trying for the same here, and playing! I was wondering, I see 2 - 85 watt panels and talk of a few "H F's " . Is this all your using for those results? I'm up where the sun don't shine, MUCH. I have 1250 watts of panels and 1160 amp hours of battery, 2500 watt pure sine wave inverter. I'm generating about 5+ KW's a day now. I expect better in june / july, but then theres dember / january which here will yeild very little.

  Ultamately I guess what I'm asking is does the sun shine that much there? Or do you have panels Iv'e missed?

         Thank's Bill
