I didn't finance it with the solar company but a portion of the install is currently on a HELOC which has a 3.25% fixed rate. Once the tax credit comes in I will have about $7800 of it financed. There are 16 480W panels for a total of 7.68kWh.

All in.

Yes, they come out, get on the roof, and then draw up a proposal.

~$14,000

Encino Man over here.

Hah, you're not wrong there.

With the assumption that utility costs will increase an average of 2% a year going forward, yes. I won't know what our excess will be, if any, until we get through a full 12 month cycle. If we do have excess, it's effectively gifted to CMP so I'll need to find a way to use it. I think a heat pump and/or heat pump water heater would be our first purchase but both of those add another initial cost to the equation.

About 400 sq ft.

Our house is in the middle of an elevated field and the closest trees are about 125 feet north of us. We also live in Durham, so the minimum lot size is 90,000 sq ft which keeps the closest neighbors pretty far away. The only thing that shades our panels are clouds.

Nice. We are on propane here which has had a more stable price, albeit historically has been more expensive per million BTUs than heating oil. Now, it's about 12.5% cheaper.

Heh, if Maine did that I suspect people would put as many panels as they could fit on their roofs just to cash in. I know I would. There's unfortunately no incentive at the moment to oversize in Maine.

With regard to the angle, I am seeing peak production of just over 5 kW these days. Back in the summer, I could hit a peak of 6.8 kW.

That's awesome. We would have had over 2MWh if I had correctly interpreted CMPs Energy Meter. It was showing we only used about 600 kWh in both July in August when we had ACs running 24/7 and the pool pump running constantly. It didn't occur to me that CMP wasn't metering the generated power that I was consuming which meant I consumed much more than 600 kWh those months. We put the pool pump on a timer and scheduled the ACs after that :)

Hah, their website is pretty awful. Certain clicks prevent you from being able to get back to your "Account" homepage.

Interconnection Agreement, PUC Chapter 324, and Net Energy Billing Agreement. The installer walked me through all of it.

Sure did! Maine Solar Solutions let me know about that.

Nice. I will probably dip in on my next bill as well. I've had 11 days in November above 27 kWh with the most recent being this past Saturday. It the clouds stay away today, I should come close to or break it today as well. I'm on track to produce just over 600 kWh for November, but I suspect December will dip to 500 kWh or slightly below. Snow cover is the wild card going forward.

Nice!

Exactly. The net metering is what makes this economically viable.

I was averaging around $134. With the increase that is coming next year, that same average would be $167.

That's awesome. We might add a heat pump or two once the IRA credits come into play. I'm eyeballing the Daikin Atmosphera model because it's the first US model that uses R-32 instead of R-410A. Only single zone at the moment, however.

I'm of the opinion that it would never get there without the current subsidies that drive market adoption. It made sense for us now due to us having a near perfect location with no shade.

The tax credit will bring the total cost down to ~$14,000. The payback period was projected to be 8-9 years when the tax credit was 26% and before the 50% supply side hike that was recently announced. The payback period should now be under 7 years.

Nice. I'd love batteries but am too cheap to pull the trigger at the moment. I might have a different opinion if we experience an extended power outage.

At this point I've financed about 70% of it through a HELOC, but that will drop to 40% with the tax credit. The interest rate at the time was 3.25% so it made sense. The rates are over 7% now so I wouldn't recommend it unless you're simply looking to stabilize your utility bill over a w 20+ year period.
