My sister and her husband’s solar system was recently connected to the grid. Their text message and embedded image nicely summarize what they think of their system:
“Here is a great shot of our home energy report. Thank you solar!”
An astronomical rise relative to their neighbors, from near the bottom to near the top.
When I received this image, I was reminded of a TED talk by Alex Laskey. Laskey found that people are more highly motivated to save energy if they know how much energy they use relative to their neighbors. Using human behavior to motivate energy conservation is a simple yet powerful idea.
And now that I see my Sister’s report, I wonder what motivated her and her husband to go solar: the fact some of their neighbors also installed solar systems, my happiness with solar power, being able to make serious money by selling SRECs, or was it being ranked 98th out of 100 back in February???

This benefits homeowners who have solar or who want to go solar. There will be no changes in the net metering cost rate for the next 15 years.
In other words, the rate that homeowners get for a kWh of electricity will remain equal to the rate that the Utility companies charge for a kWh of electricity.
Duke Energy tried unsuccessfully, and unfairly, to reduce this rate, as I described in an earlier post.
Spring is here and with it comes lots of sun. For those of you who are considering solar power or want to learn more about it, check out the Solarize Carrboro website.
With the Solarize Carrboro discounts plus state and federal tax incentives, now is a great time to go solar.
They will hold a kick-off meeting April 2, 2014 at 7 pm at Carrboro Town Hall (301 W. Main Street, Carrboro, NC 27510). At this kick-off meeting, the Solarize Carrboro team will step homeowners through the process, including solar equipment, tax incentives, installation, and financing. Carrboro solar homeowners will also be on hand to answer questions.
See their website for details on how to RSVP for the event.
They’ve selected two installers–Southern Energy Management (the company that installed our Solar Carport) and Yes! Solar Solutions.
This is worth checking out. And if you don’t live in Carrboro, check your local area for a Solarize program. There is Solarize Durham; Solarize Raleigh, Solarize Mass (for MA), Solarize Seattle; to name just a few.
As mentioned below, net metering is under attack in NC. I just got an email from Maria Kingery, CEO of Southern Energy Management (the company that installed our solar system), describing how to contact the NC Utilities Commission:
#1. Write an email to the “Chief Clerk of the Commission.” Include “Docket E-100, Sub 83: Net Metering” as the subject.
- Identify Yourself
- In your letter, please let the commission know who you are and why you decided to invest in solar. YOUR story is important for them to hear and appreciate.
- Tell the Utilities Commission: “I DO NOT support changes to net metering that will kill rooftop solar in North Carolina.
- Ask the Utilities Commission to oppose changes to net metering!
#2. Send your email to the Utilities Commission: firstname.lastname@example.org or by U.S. mail to: North Carolina Utilities Commission, 4325 Mail Service Center, Raleigh, NC 27699
I feel it is important to fight to keep net metering, to keep solar power strong in America. I just sent off my email.
Duke Energy, North Carolina’s largest electric utility, just announced they are seeking to reduce payments for solar power from 11¢ / kWh to 5-7¢ / kWh. Article here: http://www.charlotteobserver.com/2014/01/22/4632118/duke-energy-to-seek-reduction.html
While this may seem like a minor issue, it isn’t. This would have a devastating impact on the payback period for residential solar. And it would make going solar uneconomical for residential customers.
For those not familiar with Net Metering: when a solar system generates excess power, the house electric meter runs backwards and credits build up. These credits are currently equal to the rate that consumers pay for electricity (about 11¢ / kWh). So, when the sun is not shining, you get power from the electric company at the same rate.
Seems like a fair trade: 11¢ / kWh for power from the sun; 11¢ / kWh for power from the grid.
Duke Energy is greedy and wants to discount power from the sun as follows: 5-7¢ / kWh for power from the sun; 11¢ / kWh for power from the grid.
Does that seem fair?
Solar power doesn’t pollute. Solar power is a renewable resource. And contrary to what power companies say, solar power doesn’t tax or strain their power grid. Excess solar power flows to your neighbors houses, providing power near its point of generation.
We just received our bill for the month of November:We generated slightly more power than we used! The extra 29 kWh will get carried over to December. Given how much less solar energy we’ve been generating in December (because of reduced sunlight in Dec), we’ll definitely wind up using the credit.
When I received this bill, I was initially a bit perplexed. I thought our bill would be $0, but instead it was $10.42. Turns out Duke Energy (and probably all electric companies) charges a “Basic Facilities Charge” of $9.90 / month. This charge has never been itemized on any of our bills. Instead, this charge has been added to our monthly electric usage charge. In essence, it has been hidden or “buried”.
This charge isn’t just levied on people with solar. Everyone has to pay this monthly charge (if you don’t believe me, check out the rate schedule here: http://www.duke-energy.com/rates/north-carolina.asp). We are on Residential Service, Energy Star.
Since I didn’t realize this charge was hidden in our monthly bill, I mis-calculated our monthly rate (I had been dividing the cost of the bill by kWh used; and got a rate averaging 12.8¢/kWh). Turns out, from looking at this rate table, our rate is actually 9.3¢/kWh.
Let’s see what December brings in terms of power generation. So far, it’s been overcast many more days than sunny. And winter solstice is December 21. Once the days increase in length, the power will pick up.

The final inspection and connection to the grid was fast (took 4 days). The solar guys then came out to commission the system on 10/30/2012. Basically, that means they made sure everything was wired properly, they installed the wireless monitoring card and then they turned the system on.
I have to say, solar power is pretty incredible. From the moment the system was turned on, I could see from the inverter screen that power was being generated. The system makes no noise as it basks in the sun, converting photons to electrons (electricity).
Based on the first few days of use, most of which were cloudy, we generated more electricity each day than we use on average.
