True, when we signed up with Sunrun, they guaranteed production level over the course of 2 years.

More than 20% decrease in solar output in 1 year

Ok then the chance of you getting reimbursed by Tesla for lost solar production is like 0.000001%.
This is one of the reasons I wanted microinverters... one panel/inverter failing wouldn't take out my whole system. I've read enough terribad reviews about string and solaredge going offline for months while customers are left holding the bag. How we all wish to have bought our systems from V3 or be a solar-pro who could DIY an inverter replacement.
We shall see about V3. I have an issue with the install they did, and still waiting on how they are going to fix
I don't have Tesla panels, just LG panels with a Powerwall and an Enphase inverter, but my Enphase system tells me the output of each panel:
You can go on google maps and get a top down picture of your house... and use that as the background of your solar panel view. It looks more cool when all those rectangles are aligned on your actual roof
I did 176kwh the other day. Hoping to beat my 185kwh max from last year.

Model 3 has Arrived.
The crazy thing is I only have 10.4 kW of inverter capacity and generated 87.5 kWh yesterday that means I'm getting close to 8.4 hours of 100% nameplate capacity. The amount is still rising daily.
Both of my 11.4 inverters clipped yesterday, but only for like an hour or so

I just posted about total energy production of a Tesla system of given size Your post surprised me because during this month I consistently have 65+ Kwh per day (this with clipping at 7.7kw since I have only one inverter) and the size of my system is 9.6kw (24 panels x 400w/ea)
Is it possible to degrade a systems performance with very long wire runs? I also watched a video just recently about someone who cleaned off their panels after the first year and got back about 5% instantly in production (He used rainwater to avoid hard water staining on the glass)
If it was a "bad wiring job" wouldn't the losses be consistent from the very beginning? I also learned that excessive heat will reduce efficiency of any panel. I wonder if what you're seeing is a combination of many factors including more heat, dirty panels, variations from year to year, etc...
Still, 30% is a LOT! I hope you discover what the trouble is...

Long runs of wire will definitely degrade performance (this is call voltage drop which is essentially the resistance of the wire changing that energy into heat thus losses).
