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?
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.
