Who here installed solar panels on their home? How has it been working out for you?
I've started on that journey by trying to decide between Tesla roof and just panels. It's a hard choice because my roof is in not new but in a good shape. My understanding is that when panels and roof lifecycles are out of sync, there's extra headache involved - you can't replace the roof without taking down the panels and then reinstalling them. On the other hand, Tesla roof is significantly more, and I'd be giving away the unused portion of the lifespan of the roof that I have today. Not sure how to go about it.
best advice i can give you.
never combine tech.
keep em separate. your panels break, you still got a roof.

Ground based solar for the win!
Solar really doesn't work in many places. IL for example maybe gets 6-8 hours maybe of quality sun assuming it's not raining/snowing this time of year. Not nearly enough energy to justify the expense. I'd be better off getting air tight foam insulation than solar in my climate. Plus we get at least 1-3 hail storms every year. Solar panels don't stand a chance here. I don't know why people get them.

Since you don’t know why some of your IL folks installed solar panels, have you asked anyone of them to find out?
For some of us Californians, the numbers are quite close to pencil out. The electricity cost has gone up from 12 to 25 cents in the last 5 years, installing solar panels will insure the cost is fixed going forward.

I would want a payback period or break even point of no more than 6.5 years for solar installation given the many risks associated with solar panels and the systems.
Solar is not designed to succeed. They, like green policies, are designed to fail while empowering the czars. They want us all to be energy beggars.
Solar panels are physical appliances, and an 'exposed to the elements' physical appliance to boot. Such appliances have inherent life expectancies of 10 to 15 years before deteriorating and requiring replacement. They are made of plastic and wires. Plastic and wires exposed to sunlight and the elements do not last that long. Batteries, if you haven't noticed, tend to deteriorate and fail even faster. All those so called 'green' devices wind up in toxic land fills pretty quickly.
Solar panels are fine in limited use applications, where the expectation is that they need to be replaced as needed.
Wiring harnesses in cars fail pretty frequently within 15 years, and they are under a lot less stress than solar panels.

I'm going to get a mini split air conditioner which can run on solar (AC/DC).

how did you come up with the number 6.5?

Now it’s mandatory to have them for all new homes in CA. Not good.

The scale of solar just doesn't work for 80% of US homes. You'd need panels all over the yard AND the roof. Besides the Southwest, it's mathematically impossible (generally) to zero out your electric bill based on the square footage, pitch and direction most homes face for the roof. You have to have land and open sections with minimal trees.
All companies are vertically integrated and offered the same warranty. 25 years on workmanship, performance, roof penetration, parts and labor, etc… with maximum solar degradation of 14% aka 86% efficiency by the end of year 25.
Probably no chance one of them is standing at the end of 25 years. They WILL make your roof leak,
I believe PW is a luxury item.
solar is definitely a CA item. im snow covered, solar here has major limitations. sunshine from 17 to 17:09… yes 9 minutes total.
So, if your battery has given your system this off grid operation ability, then the grid can go down for weeks, and you'll have power the entire time if the sun shines.
Solar only works in specific locations. Midwest is not one of them.

No sun for 4-6 days and your food is trash by the end of it.
You could put up two wind turbines and produce the same electricity whether it's light or dark out charging a battery.
Solar is dumb in my book of life. Hydro and wind are substantially better. Obviously nukes. Solar is a god awful way to produce power and "feel" good about it. I'm into architecture too, and it makes houses look like pure shit.
I’m a YOLO guy. I blast the A/C when it’s hot and crank up the heater when it’s cold. I don’t care if it’s peak or off-peak. At the end of the day, spend an extra $100-$200/month to be comfortable is a small price to pay.
If the power goes out though, their solar system stops operating. There's no battery backup of any sort, and it cannot run independently of the grid at all.
Installing a transfer switch allows one to keep the solar system running during power failures

10 years for my current electric bill your system would cost me $291.66/mo. That assumes all my electric needs will be met. They won't. I'm $125-50/mo on average. I'm losing $150/mo if I go solar. That's in a sunny year too. Haven't had solar sunlight that would produce for an entire week here in IL. Solar only works in specific locations. Midwest is not one of them.
The math doesn't work unless you're south/north of Capricorn or Cancer lines. Basically the equator. Sure it looks good in Alaska ...

IMO there's a large benefit most don't immediately think about. Its not the fact that you get a day or so of battery backup power, its the fact that most solar systems which include a battery are built w/ different components and wired differently, making them able to harvest solar when the grid is down, while most systems w/o a battery cannot operate at all w/o grid power being up. So, if your battery has given your system this off grid operation ability, then the grid can go down for weeks, and you'll have power the entire time if the sun shines.
Personally I would double check with your installer if this will be the case. It's unusual, but some systems use batteries but cannot harvest solar w/o the grid, so once the battery depletes, you have no power just like all your neighbors. Which really sucks. Especially since it soun...

I have toured many solar systems over the years. The systems I saw that went down when the grid went down were the ones that lacked a transfer switch. A Virginia law requires a solar system to shut down when the commercial power goes out, as to prevent backfeed from harming the lineman. Installing a transfer switch allows one to keep the solar system running during power failures (same rules as for a generator). As long as the sun is shining, one can get power whether a battery is charged or not.

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?
