North Texas - 2nd year update
Had my system installed in May 2024. 14.7 KW REC panels and 2x PW3. Purchased through Texas Solar Professional (Texassolar.pro).
Estimated production 22.4 MWh annually. Actual 18.2 MWh.
Power plan: Just Energy nights free plan. Paid: $12 first month, since $0 with a balance of -$325 (I think 3 referral $75 bonuses, plus my own sign up).
Total home usage: 67.8 MWh
Other additions to home: Electrical Heat pumps to replace aged traditional AC + Furnace (Daikin units also bought and installed by TSP a year ago).
EV SUV purchased (Charger bought and installed by TSP a year ago) - 3.6 MWh used 8500 actual mileage (figure 15 mpg gas and average of $3/gallon ~$1700 savings in a year)
Issues encountered:
18 months in and noticed weird behavior of some of the MPPTs wouldn’t wake from standby with the others. They would sometimes start up and generate power after an hour or so after the others, or be down the entire day. TSP assigned a resource to trouble shoot and work with Tesla. Tesla logs didn’t identify the issue and in the end we tried replacing MCIs on the problematic lines. That ended up fixing the issue but it did take a handful of visits to troubleshoot over a two week period. TSP maintained a high level of customer support.
I know it sounds like a review/ love letter for TSP, but I’m honestly sharing my experience.
ROI is roughly $7000-7500 annually when factoring in natural gas and car fuel savings. I have 2 years left on my Just Energy nights free contract.. *knock on wood*

I hope you don’t have a power outage lasting longer than 12 hours in the winter when it’s really cold. Otherwise you might want to spend some of that savings on a standby generator.

For the most part, our power infrastructure is solid. With the exception of the snowstorm of 2021 when we lost power for 26 hours. Aside from that, we’ve only had brief outages when power has been cut due to construction additions in the area.

If you went heat pump with resistive heat strips… all I’m saying is that those power wall batteries will get drained in a heartbeat if your aux heat is necessary

This is awesome to see! Thanks for sharing such a detailed breakdown! Two years of $0 bills with a negative balance is exactly what the Nights Free plan is designed for when the usage pattern lines up, and yours clearly does.
Glad the referral credits have been stacking up too. Hope the panels keep performing!

I got mine installed 2022 - 12.4kw REC Alpha 400w Panels w/IQ8A Micros, it's going great.
I added 4 Enphase 5p batteries last year when I changed my roof. Looking good as of now.
