50 MWh!!!

Sun Nov 30, 2014 8:20 am

In just under 3.5 years of operation (it was shut down for over 5.5 months in early 2011), the Guheert PV array has produced 50.0 MWh of electricity!

Image

Since the array is now larger than its original size, I expect to produce over 18 MWh each year going forward. As such, the system should produce each additional 50 MWh in less than three years. That means it should cross the 100 MWh mark sometime in 2017.

Now that electricity has gone up to $0.12/kWh here, this system currently produces about $2200.00 worth of electricity each year.

Up next should be Tony Williams, currently at 47.9 MWh (unless I missed someone else).

Those are some pretty impressive number Reg. How much is your monthly bill from the utility ?

Nice Reg. 50MWh in 3 years that's great. I have 20MWh in 16 months. The best money I ever spent.

It just went up 66% on August 1 from $6.85 to $11.40! I don't mind paying the higher fee since I could never rent a 4 MWh battery to store energy collected in summer for use in the wintertime for anywhere near that price.

The last three big changes to our energy consumption were:
~3 years ago: Added LEAF = +2 MWh
~2 years ago: Replaced water heater with a heat-pump water heater = -3 MWh
~0.5 years ago: Added PV production = -4.5 MWh

With these changes, I am hopeful that we will be energy neutral for our nearly-all-electric home (cooktop is propane). It may not quite work out this winter because the new PV was installed a bit too late to save up as much as we likely will need. As such, we may need to pay a couple of power bills in February and March. But hopefully future winters will work out with no additional bills.

I feel the same way! Unlike some people's experiences with early-generation PV systems or early-generation electric vehicles, nearly everyone which recent-generation PV systems is pleased with the purchase. I think they have really come into their own.

Still, the adoption rate for PV is quite a bit lower than I would expect. A self-installed grid-tied system works out to around $0.05/kWh these days, assuming a decently-pointed roof with little or no shading. That's less than half the going rate for electricity here.

Your post got me to add up my production. Not surprisingly you're way ahead of me but I have generated 11.498 MWh over the last six years. Which isn't bad for four years of 700 watts and a bit over two years of 2170 watts.

For the last couple of years my electric bills have been the $16 monthly service charge plus a tiny county sales tax on usage. Works for me!


Several months ago I persuaded my local library board of trustees, of which I am a longtime member, to buy 40 235 watt panels in our power co-op community solar array (I also donated one, so we have 41) to offset some of the library electricity usage. The ROI is 6.5%, which is way better than what we are earning on our reserve funds. My picture of the community solar array here:

Our array came online about a half dozen years ago. Back then our electric bill (over the prior 2 years) averaged $225 a month. Of course SoCal Edison has jacked the rates up every year since then so I'd hate to think how much our electric bills would have been without solar. Even after adding the leaf to the equation - with our PC array we still get between $100 and $200 a year cash back for our surplus. SCE has been whining about all the solar being pushed onto their grid lately. They want to blame solar producers for their antiquated grid needing to be upgraded . . . as if it wouldn't need to be upgraded otherwise. You know ... like building more power plants?

I'm at 32.3 MWh in 33.5 months. :D

Have to check...

I am running a SMA 5000 and SMA 6000 and our system is 11.5kw system.

We originally started with a 4000 and 5000, but the new sma inverters are REALLY efficient and they were flat topping all the time. Since swapping the 5000 for a 6000 and swapping the 4000 to a 5000, we are no longer flat topping...

With a Volt, a Leaf, and a Cmax Energi, we might have to add more solar :D

It looks like Tony passed 50 MWh in February. He is currently at 50.5 MWh.

I'd be quite happy to lease a PV system despite our hydro-sourced power, because of the cost savings, but we have a slate roof and no one will put one on our South wall, despite an excellent exposure there...
