In case you were curious, as of October 2013, Cheshire had about 30 homes with rooftop solar electric panels. Here's a map:
I'm hoping to organize a couple "solar home tours" in the next month or two to help people visualize and understand what it means to "go solar!" And keep in mind, you can now go solar with no-money-down and have a net savings on your CL&P bill from the beginning.

Although President Obama is beginning to tacitly acknowledge the lies on which he predicated his call for war on Syria... and now admitting that he just wants to show Iran that he's the toughest kid on the block... I think it's worth reminding ourselves of history... and the lies that were told to involve the USA in other wars.
Due to my father, I'm fairly knowledgeable about the Vietnam War. Here's a copy of the letter he sent to the New Haven Register on December 7, 1967. His letter got him called by Senator Fulbright to testify about the truth of how we were dragged into that war.
More to come to explain the immediate consequences and long-term results of my dad speaking truth to power.

The Pentagon Papers “leaked” by Pentagon official Daniel Ellsberg gave dramatic proof of the devious and dishonest way our government, under five presidents (Truman, Eisenhower, Kennedy, Johnson and Nixon), maneuvered our nation into the war and escalated it.

As I've been explaining, I'm advocating that Cheshire respond to the state's RFP for the third phase of a program called Solarize CT. And now, the Town Council Chairman, Tim Slocum, has placed it on their agenda for Tuesday, July 9th @ 7:30pm in Town Hall. Needless to say, I plan to be there and offer as much explanation as possible. But numbers can be easier to understand in writing, so I'm explaining the economics here. And you probably want to know...
How much does it cost for a typical home to get solar panels?
Without this program, it might be normal for a 2000 sq ft home in Cheshire to pay about $32,000 for solar panels. That's based on a typical home using 700 kWh / month. For your own understanding, check one of your CL&P bills to see if you use 700 kWh / month. But in the meantime...
700kWh x 12mos = 8400 kWh / yr
So you need to generate 8400 kWh / yr. And here in CT, we're lucky that we have a law allowing for net metering. Net metering means that although you use electricity at night, if your solar panels generate more electricity during the day, the two get netted and you do not need to pay for generation or delivery services.
How many solar panels does a typical home need to generate 8400 kWh / yr?
A house normally gets about 7 kW of generation capacity installed. And kW is how solar electric panels are normally described by manufacturers and installers. But of course, the panels are not generating electricity all the time, such as at night. In fact, the CT DEEP suggests that the typical generation capacity of solar electric in CT is 13%. In other words, on average, panels work 13% of the time. So here's the calculation to to get you to 8400 kWh / yr:
(7.1 kW) x (24 hrs / day) x (365 days / yr) x 13% = 8100 kWh / yr
So much does it cost to install 7.1 kW of solar panels?
Results from Phase 1 of Solarize CT (occurred from Sept 2012 to Jan 2013... and Phase 2 is ongoing) showed that homes in Solarize towns* installed an average of 7.1 kW at a cost of $27,000 before rebates & tax credits. Among the other 165 and during the same period, homes paid an average of $35,000 for a similar installation.
Those numbers are typically discussed in terms of $ / W or $ / kW. So the Solarize towns were paying about $3800 / kW and non-Solarize towns were paying about $4900 / kW. And those costs are typically broken down into hard costs (hardware) and soft costs (labor).
The hardware comes from China and those costs are not dropping dramatically. They were probably about $2000 / kW in 2011 and about $2000 / kW today. Not stable like hard costs, the soft costs are dropping. They were about $4000 / kW in 2011 and are now in the range of $1800 to $2900 / kW.
It's the soft costs where this program hopes to help homeowners save money, as well as do right for the environment. Here are some ways where economies of scale can be achieved quickly with this program:
1) CT has 1.4 million homes. We also have about 70 to 80 solar electric installers. With 169 towns, we have about 13,000 initial contacts to be made between solar installers and town building inspectors. Yet CT now has only about 5000 solar electric installations, including about 30 to 40 in Cheshire. The initial contacts between installers and building inspectors takes time. By participating in this program and suggesting a preferred installer, the goal is to reduce time costs, such as this.
2) Ten installations in ten towns will require more travel time than ten installations in one town.
3) The cost of customer acquisition for solar installers is quite high. This program hopes to leverage existing social networks in town to spread the word about the opportunity. It's similar to Cheshire's Neighbor-to-Neighbor program for which we just got a letter in the mail this weekend. N2N demonstrated that this approach can be successful in increasing awareness.
Anyway, these are some of the ways in which this program can help reduce the high cost of solar electric. And while history cannot predict the future, it does suggest that the program itself may help reduce the cost of solar electric in Solarize towns. And while solar electric panels probably now cost around $4500 / kW statewide, I suspect this program could help reduce those costs even further.
It's entirely possible that Cheshire could average $3750 / kW. That would place the cost of 7.1 kW of solar panels at $26,600. And then there's the state rebate of $1750 / kW, reducing the cost to $2000 / kW. And depending on your income, there's also a 30% federal tax credit. That would reduce the cost to $1325 / kW.
At $1325 / kW for 7.1 kW, you'd pay $9400 for your solar electric installation.
Now, let's break down your electric bill. You probably have three parts:
1) generation services... this is the relatively new program where you choose your supplier.
2) delivery services... this is CL&Ps business. They buy the electricity. It may come from the nuke in Waterford, a gas plant in Middletown, a hydro plant in Quebec or somewhere else. But it doesn't matter where the generator is located, CL&P handles the delivery.
3) interconnection services... this also gets paid to CL&P.
For all of the solar electricity that your panels generate, you pay neither generation nor delivery services. However, as long as you are connected to the grid, you'll pay the CL&P fee which is currently $16 / month.
Assuming that you stay grid-connected, you can only avoid the generation and delivery services. An example rate for these two services is $0.07 / kWh for generation and $0.05 / kWh for delivery, but check your bill to see exact numbers.
At $0.12 / kWh for 700 kWh / mo, you pay $85 per month for your electric bill. That means you pay $1000 / yr for electricity.
$9400 / $1000 per year = 9.4 years payback
And with an estimated useful life of 20 to 25 years, this means that after ten years your electricity is free!
Ok, ok... it's a bit more complicated than that. But this story is already really long. And I imagine you're already bored. :) So I'll end it here and say... don't be shy about questioning me. I'm trying to give you the basics, while giving the most pertinent details. And when it comes to energy, this stuff tends to require lots of explanation.
Hope this was helpful. Please be in touch! If the Council approves the RFP response, I understand the State will be announcing their decision by July 31 with the program to occur from September 2013 to January 2014. So things could start moving fast.
p.s. In the interest of full disclosure, although I'm currently a full-time student at Yale's Environmental School, I'm interning this summer at CTs Clean Energy Finance and Investment Authority (CEFIA). CEFIA is the quasi-public agency that is running the Solarize program.

Have you ever wondered about the owner of a particular property in Cheshire?
Or perhaps you've been curious where the new (post-2011) voting district lines have been drawn?
Or a variety of details about Cheshire properties, such as:
- Aquifer Protection Area
- Prime Farmland Soil
- FEMA Flood Zone
- Open Space
- Cheshire Zoning
If so, you can find details here. And you should also be able to navigate to find other towns in the greater Waterbury area.

As I mentioned in my previous post, Connecticut faces some serious electricity problems. This is due to our reliance on centralized generation (CG). An alternative to the CG -- typically provided by nuclear, natural gas and coal-fired power plants -- is distributed generation (DG).
Probably the most common existing form of DG is a household generator. (I quickly found a 4 kW generator online for $400, while a 7 kW generator is listed at $900. Installation by an electrician may run the cost up to $2,000.)
Another -- and increasingly popular -- form of DG is solar electricity. It's also known as a photovoltaic array or PV. Solar electric is the cause of the Solarize CT campaign. And it's the Solarize CT campaign that I hope to bring to Cheshire as Solarize Cheshire!
Why undertake a campaign? Why bother?
The Solarize campaign concept began in Massachusetts and had demonstrable results. So the State of CT decided to undertake a similar campaign to increase the use of solar electric in The Land of Steady Habits.
Thus far, the campaign has existed in three outreach phases:
- Phase 1 occurred from Sept 2012 to Jan 2013.
- Phase 2 is ongoing, beginning around April 2013 with a scheduled completion of July 2013.
- Phase 3 has not yet begun, though the State's RFP was issued about three weeks ago with a July 12th deadline... and the campaign to be undertaken from Sept 2013 to Jan 2014.
It's the current RFP of Phase 3 that has my interest because the program has shown clear results.
Not only has the program reduced the cost of solar by about $8,000 / home, it's also increased the number of homes getting solar electric installed by ten-fold. That means more local jobs, rather than jobs in CG plants that will probably be both distant and have negative impacts on the environment.
$8,000 is a lot of money. How do I get that savings?
A typical CT home buys about 7.1kW of solar electric. Of CT's 169 towns, four participated in Solarize Phase 1. Within those four towns, the average cost of one kW was about $3,800. Within the other 165 towns, the average cost of one kW was about $4,900.
So instead of paying about $35,000 for your solar electric installation, you pay about $27,000. And yes, at $27,000, the economics make sense. Just consider what you pay for your monthly electric bill.
$27,000 is a lot of money. How does that help me?
You probably pay around $100/mo to CL&P. That translates to about $1200/yr. And with an estimated 25 year life for solar electric panels, you'd get a payback at around 22 years. But that's not accounting for benefits like the 30% federal income tax credit that you can take.
More on the numbers later. I'll leave it here for now and try to elaborate further this weekend.
