Installing Tesla Solar Panels on my House

TL;DR that I ended up installing Solar ... but mostly because it will be a "fun toy" to play with versus a true economic payoff and/or virtue signaling.

Here's my notes on the design, installation, and operation (1+ years so far) of Tesla Solar Panels. If you are new to Solar, here's some misc. background info to come up to speed and good to know about NEM. Here's my design process and installation - also see the page about the Tesla 7.6kW Inverter ... plus I would strongly encourage putting a "Critter Guard" around the solar panels so nothing builds a nest under them and/or nibbles on your wires.

I'm using Powerwall-Dashboard to track production/usage (highly recommended) and here's my customized JSON used to graph the results.
If you really want to be knowledgeable and analyze things, be sure to check out the spreadsheet ... which can be used for your solar system.

So far it's working well and I'm glad I did it. However, from a pure economic point of view, I should have invested in the S&P500 instead. I knew that going in ... and while I could say I did it to go "green" (and certainly paid "green" to do that!), the primary reason for doing was to get a first-hand exposure and have fun playing with the data (LOL I'm not the only one! ;-) ... and that's been a big success as seen in the graphs below! ;-)

2023: Solar goes live on 9/1/2023 (might have turned it on a bit earlier ...) and we are converting photons into electrons! ;-)
2024: DIY replacement of used gas cooktop with a (used) induction cooktop (how is that for re-use?!?) so should see slight shift from Therms to kWh. 29 day "Skibbatical" in mid-Feb/Mar reduced both kWh & Therms. The months of Feb/Mar/Apr were warmer than typical, so usage further decreased.

Here's what a monthly report looks like from PowerWall-Dashboard ... remember to click to see BIG!

Solar_Report_2024_07_01-2024_08_01.jpg

Maximum production day was 47.9kWh on May 8th, 2024

2024_05_08 Output

Not surprising to see solar production drop during Solar Eclipses - more on the April 8th, 2024 Partial

2024_04_08 Output

2023_10_13-14-Solar_Output_Partial_Eclipse.jpg

Drop in energy usage when the house was unoccupied ... but only from ~15kWh/day to 9kWh/day

"Vampire" load is Radon Fan (7x24@60W), Internet/Webcam (7x24), Fridge (7x24 but cycles), Lights (on timer), Furnace Fan
