Even better, what if the Powerwall can return electricity back to the grid during the peak hours. you can store at $0.17/kwh and sell it back at $0.48/kwh!!! You’ll be able to make back the ROI for the Powerwall in no time![/quote]Why would you waste time and money with a powerwall install when you can do the same thing for way less money with a lead acid AGM battery solution. Powerwall is probably one of the dumbest things out there for a home installation but the hype is real is real I guess. Lithium Ion has pretty much one thing going for it and that is weight. Of course in your home weight doesn’t matter so why would you want that much lithium (if this thing catches on fire my house is gone) in your house.[/quote]
I do agree it is too pricey. But I am glad Musk took that first step and rolled this out. How they will be able to provide enough battery for the model S, X, and III and the powerwall will be interesting to see.

GuestI love the story of Elon Musk. He’s the nerd that everyone now admires.
Powerball is part of the vocabulary.He was bullied in his youth and now he’s dating models and meeting presidents.
Solar was so derided a couple decades ago. Now it’s cool and a must have status symbol. Not to say that people get solar for status, but there is status in having solar, not to show wealth but to show that you’re smart and contribute to lowering your carbon footprint.
It’s lifestyle status. There are those who embrace solar, and those who still hang on to big oil and the incandescent lightbulb.

Freaking awesome.

yes, pretty awesome.
Do you feel warm and fuzzy about your solar array?

very nice. my max so far is 35 kwh, yesterday got close at 34.8. based on 5.25 kw system.
how big is your system?

My max is 24.7kWh with a 3.8kWh system.This year have a lot more “bad”/cloudy days than the past 2 years.

ParticipantMy max is 31.54kWh with a 4.5kWh system. Just wrapped up the first year of solar last month and created 8200kWh with a total usage of 9700kWh, only paying SDGE for the difference of 1500kWh. Payback period on track for 5 years with 12% IRR after 10 years! Yeah!
June 19, 2015 at 6:12 PM #787357svelteParticipantGot 71.1 kwh yesterday with 10.4 kw system.
Let’s see how they compare
6.83 = 71.1/10.4 – svelte
6.66 = 35/5.25 – ocrenter
7.01 = 31.54/4.5 – montana
6.5 = 24.7/3.8 – ANMontana, looks like you’ve done best so far!
Also interesting that our results are so close together…looks like one can expect between 6.5 and 7 hours of energy on the BEST day of the year…
That’s probably on a crystal clear long day with zero clouds. Worst day will be much harder to compare apples to apples, since clouds will vary over the different homes.
June 19, 2015 at 11:36 PM #787360ParticipantKeep in mind that due to may gray and june gloom, how far you are from the coast makes a big difference. Also, since may and june are probably the two best months in total sun light, it sucks when you’re closer to the coast. Where I live, I do get some marine layer in the morning, but it burns off, but not as early as those who live east of the 15. That’s probably why you’re seeing the difference in amount to total hours of energy.

What you are really saying here is the efficiency of your solar system correlates with the number of lizards around your house. More inland, and more lizards, and better efficiency for your solar panels.
June 20, 2015 at 7:35 AM #787368svelteParticipantI was actually surprised at how close together the numbers were – less than 9% difference.
This is not even taking into account different brands, roof angles, etc.
We are about 10 miles from the coast as the bird flies, and we’ve seen a few days this month where there wasn’t coastal fog first thing in the morning here. I didn’t see much as I looked westward either, so I would imagine there is at least one day this month when coastal fog had minimal impact unless someone lived just a few blocks from the beach.

Similar results on PVOutput.org, the majority are all around the mid 6 range.

Not only are we most infested with lizards, our lizards are most adapted to crazy heat and they’re well adapted to the many walls that we have.

Yes, gloat about your houses with too many walls. That’s fine. But are you sure those things are even lizards? Our lizards in the real lizard land are so big we actually strap solar panels on them to increase our efficiency.
