Generator for home during power outages

[pronstar]

As promised update:
Just had the solar system installation finished on Friday. 44 LG panels with Enphase IQ 7+ micro inverters, with a Tesla Powerwall 2 for backup.
The first day, being cloudy, I was generating 75% of the power I needed. Yesterday, I generated 100% and actually sent more to the grid than I used.
The only things not backed up by the battery is the HVAC system and the hot water heater. I'd need at least 2 more Powerwalls to run those as well.

Solid system

Pretty much what my two solar-company-owning buddies told me to get.

You have per-panel metering as well, right?

What was your total price?

I haven't checked that yet. I know there's aggregate in the enphase web page, and it sees all the microinverters.

If you have a monthly payment, are you comfortable sharing the loan term, percent and payment?

For me, that would take 45 years to reach breakeven if the system produced 100% of the power. And that is not taking into account the continual panel output degradation nor the expected useful life of the panels (less than half of the years to reach breakeven).

The main thing I have a problem with is spending that kind of money, and not being able to power AC/heat.

Uh.... The materials for that come out to less than 30k. They charged 52k to install?

I am asking because I am already pricing a similar system (minus the powerwall which is not a good value) and it's not even 18000.

There is a tax break to consider, but yeah it's not what I would call cheap.

I see my neighbor just got his Generac and a well used propane tank. Nice of the weather allowing him to get out and paint that rusty mofo.

That’s actually a good idea. I wonder how long say a 15kw rig would run on a 500 gallon propane tank?

A long time under light load.
Under 3/4+ load, about a gallon an hour.

I'm sure the company that installed mine made a nice profit, but I don't know how you can get 44 panels, 44 micro inverters, a Tesla Powerwall 2, plus the Enphase controller for 30k.

1.9% for 20 years for I think it was $385/month.

I did check and it shows how much each panel is producing.

I have portable heaters that will do for night time.
As long as the sun it out, the system has enough power to run the HVAC system since it's over 16.5kw output. At night, it's a different story since the single Powerwall won't be enough to power the HVAC system.

The system is mainly for peace of mind, I know it's going to take over 20 years to get a ROI on it (if ever).

We don't know what electricity prices will be in the future.
I will say, I've worked for electric utility companies since 1981. It was about 8 cents a kwh in '81.
It's about 10 cents now.
They can generate and distribute way cheaper than you ever will.

Just keep some sort of emergency power at the ready.
Chances of a week long outage are pretty good. Mother Nature is a fickle bitch.

Propane , it will hook right up and there is no build up of gas crude , runs smother also

 

[Kobiash1]

I have solar with a battery. My electric bill is around $20. The federal tax credit payed for them.

https://www.renvu.com/Talesun-450W-144-Half-Cell-Mono-Tier-1-Bifacial-Solar-Panel 25 = 6774.25

https://www.renvu.com/Products/Solar-Inverters/Grid-Tie-Microinverters 25 = 3519.6

https://battlebornbatteries.com/product/12v-lifepo4-deep-cycle-battery/ = 8000 USD

^ 10 x 100 ah at 12 V = 12Kw or so.. The Powerwall is 13.5

Victron Energy SmartSolar MPPT Tr 150V 100 amp 12/24/36/48-Volt Solar Charge Controller (Bluetooth) = 780 USD

Now I still need the racks and the wire which will run another 2 grand. so total maybe 22000 plus installation.
