Journey to Solar – Part Six, A Month to Month Comparison

We’ve been solar almost six months now and are getting great results. Once we have a full year of experience, I’ll do a complete breakdown of costs and energy generation.

But, to share some perspective, I want to demonstrate how our electric bill breaks down for the month of August – generally our highest bill of the year.

Our electric bill for August 2012 came in at a whopping $464.60, and that includes the discount we received by participating in SCE’s Summer Discount Plan.  In total, we used about 2126 kwh (kilowatt hours). Yikes!

Now, compare that to this August 2013. Our net usage from the grid was 434 kwh. Our current electric bill for August is $14.19! (Again, participating in the Summer Discount Plan generates additional savings.)

The bill for August of 2013 also includes the monthly cost of operating our electric car that we did not own last year. So, when you factor in about $150 we spent in gas last August for my husband’s car, that brings our total monthly savings to $600! In one month!

We drew 938 kwh from the grid this August, sold back 504 kwh to Southern California Edison, for a net usage of 434 kwh.

In terms of charges from SCE for solar customers, here’s how it works – when your solar panels are working during the day, your energy generation goes first, to supply electricity to your own home, and second, back to the grid. If you generate excess energy during the day beyond what you consume, you sell it back to the grid. At night (when solar panels sleep along with us), you draw your electricity from the grid.

If the amount you draw from the grid during the month is more than that you sell back, you owe SCE. If it’s the reverse, the electric company owes you.

Solar customers are placed on an annual billing cycle, where charges and credits are accumulated throughout the year, and you true up at the end of one year of solar energy generation.

So for the month of August (technically from July 22 – August 20th), we generated 1168 kwh from our solar system and drew 938 from the grid for a total usage of 2104 kwh. This is pretty close to our overall usage last year, but the difference is that 100% of our usage last year was from the grid and now the majority is coming from solar.

Of the 1168 kwh of solar energy we generated, we used 664 and sold 504 back to the grid.

Bottom line – a $14 electric bill!

So for now, I’m basking in my $600 savings for the month. Even more reason to love the sun. Keep it coming!

These babies really are a beautiful sight …
