How much do you pay for electricity?

[FlatSix911]

Free with Solar... any additional power is purchased at time of use rates starting at $0.18/kWh with PG&E
TOU Rate schedule... (Off Peak = $0.18, Part Peak -= $0.25, Full Peak = $0.37) Annual True-up = $27 Credit

Just received my annual true-up from PG&E for 2018 ... not too bad with a (-$27) Net Credit for the year.

$30/mo charging on a 50a breaker between 8pm and 2pm. $50/mo for larger breaker.

My usage works out to about $0.06 kWh.

Does your solar offset the natural gas useage as well?

 

[Holo]

You guys are killin me! I'm almost sorry I started this thread!

 

[RFernatt]

$0.12/kWh here in WV. We don't have anything like TOU, but do have net metering. With a solar system offsetting my annual usage of an all electric house and cars, we pay $5/month for electricity (minimum charge to have a meter).

For you Solar guys, what did your install cost you and how large is it in kW.
If you know, how many kWh did it generate in the past 12 months?

My solar installation was done long before panel prices came way down, so the cost is not meaningful in today's environment (my array was not cost-effective and was budgeted as part of the cost of a future electric car). The size of the array is 2.17 kW and the production in recent years has been:

2013 3327 kWh (11,977 megajoules)
2014 3217 kWh (11,581 MJ)
2015 3159 kWh (11,372 MJ)
2016 3227 kWh (11,617 MJ)
2017 3277 kWh (11,797 MJ)
2018 2849 kWh (10,256 MJ) (through October)

Since the array is ground mounted, I adjust the pitch of the panels from 15º around the summer solstice to 55º around the winter solstice in 10º increments, to increase production. I also pull snow off with a window squeegee mounted on a 16 foot painter's pole.

^ Panels at summer solstice pitch of 15º.

No, only the electric usage is offset.

 

[Feathermerchan]

So 1 Megajoule = 0.277778 kWh
11,644 (~AVG) Megejoules is about 3,234 kWh?
At about 250wH per mile that is about 13,000 mi per year if you could capture all of it for driving.
Not counting losses.

Funny,
I got a call from Tesla energy last year and was told that based on our very low rate in Southwest Washington (just over 8 cents/kWh) that it would take 85 years to break even on a Tesla Roof.

 

[Holo]

But they tried to sell it to you anyway?

 

[morrisdl]

24/7 rate: 11.5 cents/kWh

Nope.

Our system is 18.9 kW. It, along with monitoring equipment for our whole house, was $72k (before federal tax credit). Our annual production is about 21,000 kWh.

Based on a conservative estimate, we expect a lifetime production of about 600,000 kWh.
That comes out to paying 12 cents/kWh for my next 35 years of power.
Once you take out the rebates, net metering, etc, it is 1.5 cents/kWh.

This is in Minnesota. The system would have been much smaller in a more temperate local, and smaller yet with a better spot for solar.

Solar, for the long haul, is a no-brainer.

We were .13-.15/KWh TOU (off-peak), until this year. First half $.24, and ending at $.22/KWh flat unit charges. Big jump after Eversource got its tariff past the DPU.

 

[Knightowl]

I just called my energy supplier to complain about the ever increasing generation costs. It got me to really focus on how much I was paying per kWh. All in, including generation, distribution, assorted fees and taxes, I pay $0.26 per kWh! That seems REALLY high to me even living in the Boston metro area. So I'm really curious. What do other people pay around the country?

10.26cents/kwh for me in colorado springs co, but I am pretty much fully self powered now on solar so just have a $15/mo grid connection fee.

For you Solar guys, what did your install cost you and how large is it in kW.
If you know, how many kWh did it generate in the past 12 months?

11.34 kW System: (36) 315W Panasonic roof mounted panels and a SolarEdge 11400 inverter
Total install cost was $32K before the 30% federal tax credit
Oct 2017 - Sep 2018 generation: 14,600 kWh (a bad year for rain though, so probably a bit below average)

 

[dgpcolorado]

So 1 Megajoule = 0.277778 kWh

At about 250wH per mile that is about 13,000 mi per year if you could capture all of it for driving.
Not counting losses.

1 kWh = 3,600,000 joules = 3.6 MJ.

I average about 285 Wh/mile because my S60 is less efficient than a Model 3. I do about 20,000 miles a year but most of my miles are road trips using the Supercharger network and some of my local charging is at public charge stations. So, most of my charging is away from home.

Given that, my small solar array covers all of my home charging and household electricity use. Most people with solar have much larger arrays than my 2170 watts.

My 2010 DIY system cost $9K after rebate and is 7.1 kW. Sorry, I don't know what it produced in the last year. My Co-op's idea of net metering is to charge 9¢ for any time the meter spins in my direction, and 5¢ when it spins in their direction. They used to do true net metering, but then unilaterally changed. I produce more than we use, since that's how the system was sized. My energy use is net zero, but my electricity charge is not.
