Does anyone have (a non-political) opinion on Tesla Solar? And/or how I should think about getting panels (and battery) installed at my house?
From my conversations it was a complete mess to get installed, with poor communication on their end. After it was installed he had 2 issues within 2 years resulting in them needing to replace hardware.
Add in that it was quite expensive, he is not a happy customer.
They literally work with their top influencers for FSD to make it looks more impressive than it really is.
He even talks about how everyone was having problems but "for whatever reason it went perfectly"... and it still took 8 months

For the installation - most roofing companies will install the roof mounts and screw on the solar panels for $1.5k-$2k (might be different in your area, but still cheap). An electrician can be hired to make all the solar panel connections and the grid connection for a few hundred $$$.
As the Project Manager - you'll need to source the panels, file the permits, and hire the roofers and electricians. https://www.solarwholesale.com/jerry-rig-everything/ can assist (assist, not do) all of that for you for a cheap price. $10k-$15k with Solar Wholesale will get you the panels and cables you need, plus the engineering drawings, the permit paperwork, and etc. (thank you for the great Solar DIY series Jerry!)
For $20k and working as the Project Manager yourself, you can get what most solar companies will charge you $50k for. Which is ballpark inline with construction project management costs - typical residential construction project management cost 40-50% of the total project budget. A lot of those projects as complex enough to warrant those fees, unless you have a lot of experience, but in my opinion adding solar to your roof is not a complex process and does not warrant those fees.
Political=> he did a full blown Nazi salute twice and has been working to have millions fired from their government jobs. The conservatives who don't seem as bothered by that have never been interested in EVs to begin with and his liberal fanboy customers will never buy from him again now. He is extremely unpopular in Germany and China's Tesla market is being out competed. I don't think that makes Tesla look good long term, so I'd be cautious about a long term investment with them like rooftop solar. That's just my opinion anyway.
Just talk to your neighbors about reputable local installers. They'll have panel and storage options.
That said, because these things are largely commoditized, there's some turmoil in the market. Our (excellent!) local installer was saved by the PPP during the pandemic, which was a bit of a sobering thought -- they're the ones backingthe 25 year installation guarantee!
Then Sunpower (our panel vendor, and one of the higher end ones, at that) went out of business. Our monitoring system continues to work thanks to the work of the bankruptcy courts, though it's been transferred to a company who is trying to support those assets be having a freemium model.
In the bay area, it might be cheaper to opt into 100% renewable rate plans from CleanPowerSF or Peninsula Clean Energy. (Silicon Valley Power is 100% renewable by default, IIRC.)
I don't know if the Cybertruck will follow the same pattern, or if the whole company has jumped the shark, but if we're looking for non-political opinions I would not necessarily write them off on quality issues alone.
(permitting requirements kick in above 3.68kW, see nice chart at https://www.energynetworks.org/assets/images/Resource%20libr... which gives the rules for ANY size of power station)
1. The installer you choose is more important than anything else. The panels are pretty commoditized at this point. The battery cells are pretty much commoditized as well (they are 2-3 companies all of the major battery companies use). Your biggest worry is not if, but when, things break. Most well known manufacturers (REC, Enphase, Canadian Solar, Hyundai, etc.) have good warranty policies, but you need someone to coordinate that - so make sure your solar installer does that on your behalf.
2. A Powerwall battery is 13.5 kWh and has a 11 kW inverter. The base is $8k and $6k for each battery expansion. A similar, well known, brand EG4 sells the same battery for $3.7k and a similarly spec'd inverter is around $2.5k. Generally speaking Tesla installers quote much higher on labor than others too.
3. From the installers I spoke to they dont really like working with Tesla.
4. If you live in a place like Texas, Florida, etc., I wouldn't even bother with batteries unless you have a relatively small house. Most houses suck down so much energy that a natural gas generator is way more cost effective.
