Nice to see prices drifting down. Now that sales cost is being limited, solar will really take off.

Tesla Solar Panel now $2.85/W instead of $3.49/W

@kengchang Thanks for the notification. The most recent price for SC330 panel install was actually $3.39/W (discounted in April from $3.49), but the drop is still significant. I’m helping someone else and the Tesla solar advisor is saying new pricing has reduced benefits in warranty and production guarantee. Quote with old pricing includes 25-year warranty (20+5 years) and a production guarantee with payback when production falls below stated values each year; he said quote with new pricing will not include production guarantee and only manufacturer warranty of 10-12 years. Not sure on the last part because I thought California enforced some minimum system warranty. What did your new quote include in terms of warranty and production guarantee? Thanks.
Below. What's the point of production guarantee though? It's not like panel will suddenly die, which is covered by warranty?

It reassure's that the installer will "compensate" you if the system does not produce the power as estimated.
Sample contract below:
How do you know the $2.85/W is for 330W panel rather than 300W Q.cell?
Because when I get my first quote from Tesla, the cost per watt is align with the price in their Design studio, However, it is a 300W Q.cell Panel. After I requested to upgrade the panel, I got a revised quote with Panasonic 330W Panel but the cost per watt become more expensive and there is a "Premium panel cost" in the breakdown of the cost.
So I think the $2.85W is still refer to 300W Q.cell Panel, but I maybe wrong.
Looks like these panels are discontinued. Check out panasonic's website. That would make sense why the now cost less perhaps. You don't want to install old technology if you are buying now.

Interesting. Here is my contract from Tesla. I have a longer inverter warranty and the production guarantee. (BTW, we almost needed the production guarantee this year because Tesla installed 6 panels wrong. They weren’t completely off, but not performing up to spec. Once Tesla realized they might have to pay us, they finally sent someone out to inspect the system after 5 months of calling). Customer service is terrible FYI.
Here is the rest of the production guarantee clause
SC series is Solar City branded Panasonic Panel, not even listed on Panasonic website. Is N330K the equivalent?
My system is designed as 9.24kW / 28 panels = 330W each

So guys, as much as I hate going back to Tesla, the prices are basically 30%+ lower than Sunpower. The Panasonic 330 is $2.85/w while the Sunpower system are closer to 4.1/w. Part of the price difference is because my house is consider a difficult install, therefore it will cost more problems for small contractors that install Sunpower panels. Since Tesla charges a flat rate, it makes no different.
The panels will live past 20 years easily, the issue is the inverter. They simply die after 10-15, it's almost a given.

Then get the extended warranty. SolarEdge have extended warranty up to 25 Years about $200.

I've been digging into this strategy change and am loving what I see. Ran my address in PA....$2.50/Watt installed before the tax credit(no state incentives). I would be forced to get a 4/8/12/16kW sized system, but I'd make that sacrifice if I were buying right now.
Imagine you have a small ranch home and need or can afford a small array. $2.50/W for 4000W is a phenomenal deal.
Hoping they can rapidly add product size tiers in between and take back over solar installs. They will absolute destroy Vivint and Sunrun once they do so.
