whats your total payback time, or is this some lease nonsense

That isn't the only reason to go solar...

lets not pretend valve cares about the environment

Goddamit you tool, I understand the how thermodynamics works.

Do you people really find it impossible that mass adoption of renewables could change the energy cycle in ways we don't understand?

Easy homes, you have just been slinging the pejoratives today. You made it sound like you didn't understand the first law of thermodynamics. And nothing you wrote has changed that.

I think the mass adaption of devices that harvest/harness free solar energy will be a nice diet for a planet that is already overweight with excess energy some assholes keep digging out of the ground. Even if we got to 100% solar we still have the accumulated heat buildup of the last few hundred years to get rid of before it's a problem.

Especially considering that there's evidence it already does.

Still, I'd prefer that over burning shit

Straight cash, homie.

Pays for itself in 27 years


If we were concerned about it covering its own costs we wouldn’t have done it in the first place.

What's the cost per guaranteed KWh production?

What's the cost per guaranteed KWh production?

I don’t remember.

It’s expected to cover 98% of our electricity usage costs per month.

if things keep up as they are, I'll pay about 9.1¢ per KWh over the life of the system.

The guaranteed production is 11.6¢ per KWh.

I have the original paperwork somewhere.

Something neat I didn’t realize would happen.

When grid power is active, the Powerwalls supplement the solar to keep us off grid as much as it makes sense.

It does this for both sides of the system, not just the panel that is wired to the Powerwalls, but for the grid-tie panel that goes dark when utility power does as well.

that is the proper way to maintain a battery.

Thanks guys.

Tesla Gateway has a built in web server that shows its real-time power status.

Got it on the iPad that I wall mounted in place of the old alarm panel.

Went straight battery after the sun went down.

The batteries hit 47% at around 1am and went into save-it mode.

Then the gateway switched to using grid power. We were back to Solar at 7:35'ish.

Shortly after there was enough solar for the house and charging the batteries and we were off grid.

Took about 4.5 hours to charge the batteries back up too 100% while powering the house too.

And now this.

That's pretty f'n cool. Good on you man.

so all im getting out of this is that your batteries cant even last the night

Supporting the full house? They could go longer if I told them to drain to 0%.


If grid power goes down a lot of stuff won’t get any power. And there would be solar input.

I bet we could get two or more days on battery without any PV input.
