It’s interesting that not making bets is essentially making bets.
Making bets in stock market >> making bets in solar panels on one's roof.
I view installing solar is like buying an asset be it a house, or an investment. You fix the cost while the cost of electricity keeps going up over time. Then in a decade or less once the cost of solar is paid off, you’d get free electricity for the next couple of decades.
It's all feelz. I prefer numbers.

$.333 /kWhr x 356days x 8.36kWhr/day = $1,016 (tax free, BTW)
I should note that $.333/kWhr is a baseline rate. Anything over baseline is $.417/kWhr.
March and October bills include a $38.39 climate credit that all Californians receive. I usually owe PG&E somewhere between $100 to $200 at true up.

Right, but you chose to put feels and solar industry sales pitch canned phrases into your post instead of ##s.
"Investment in the house", "free electricity", "rates will go STRATOSPHERIC" - this the stuff I hear every time a boy with an electric scooter, iPad and some solar company badge shows up canvassing the neighborhood.
If one scavenges a run down battery to use for home storage, are those batteries still efficient even if the capacity isn't so great? Supposed new EV battery is 95% efficient (usable power out is 95% of the power fed in), is a run-down EV battery that only gives 1/2 the driving range still that efficient? If the efficiency is also reduced, then you'll need to expend more money for more solar panel, defeating the cost benefits.
Was just looking at prices for complete home systems with batteries. It's starting to look like giving the big middle finger to electric company is cost effective. If one's house is totally off the grid, will the electric company try to charge you just for heck of it? Also, how much red tape is involved in electrical permits? It's amazing to me that the electric company and California are so badly run that ditching all the economies of scale that a compact neighborhood offers is still better to go it alone.
Maybe you guys see something I don’t.
Great question. Research shows that Tesla battery degrades at around 1% per year and it flattens out after 10-20% so the capacity should still be around 80-90%.
Solar panels are guaranteed to have 92% capacity after 25 years. That’s 8% degradation. They have a system installed to monitor the solar panel efficiency. If any panel degrades more than that, they’ll replace it for free as part of the 25-year warranty.
From the battery size perspective, the Cybertruck is a great deal. Backing out the numbers, the Cybertruck will likely have a 175 kWh battery pack for 500-mile range. This is equivalent to 13 powerwalls while each powerwall sells for $14k.
Watch out Tesla charging went up to about $0.40/KWH in case if anyone is price cautious.

SunnyvaleCA,
My Tesla has 80k miles. The batter has degraded 10%. Sibling’s Tesla has 90k miles while her battery has degraded 6%. Wife’s Tesla is 1-year old. It has degraded less than 1%. Performance is still good. I’m not familiar with Leaf and other EV’s.
What I don't know if if you can buy a leaf cheap enough for it to be worth fixing.

In California, you can get a used Leaf for "free" if you are "income limited". That is, PG&E will give you $4k (if for instance, your family of four makes less than $150k and lives in San Mateo county) plus the feds will kick in a 30% tax credit if you a buy used EV from a dealer. Terms and conditions apply. YMMV.

. It would cover my monthly electricity bill of $230/mo on average.
Looks like PG&E just upped summer rates to $.49/kwHr for above baseline usage during peak hours (4-9pm) summer months. Yikes. For the amount you use, it be insane not to get solar...
Amazingly, the solar works even on cloudy and rainy days.
Cost is $17.4K after tax incentives.

You mean like in a "Better than nothing..." kind of way.

Incentives should be unconstitutional. Where's my $7,000 check?
Thanks to concepts like these high bar incentives(90% of the population are not in a position to lay out $17K to reap that reward) concepts like "reparations'"
are fair game. If not for this cockamamie, they would have been laughed down and ran out of town.
As the result of ever-falling costs, the Bloomberg analysts project that by 2050, wind and solar technologies will generate a most 50 percent of total electricity globally,

I did the math of Tesla solar panels. Cost is $17.4K after tax incentives. It would cover my monthly electricity bill of $230/mo on average. Add in a powerwall will increase the cost by $8k. Without the powerwall, it’s about 15% ROI. What am I missing?
