I'm looking at my nest usage and it shows on cold days I'm running heat for about 2-3 hours max. My understanding is that heat pumps are generally something that will consistently run just at variable speeds depending on the temp swings but if I'm only using the heat 2-3 hours a day, would that...

Are those numbers based upon just heat pump system only or total consumption for your house during those months?

Just to be clear, this is 720kWh for the heating portion of your heat pump? How many months is that for? I'm trying to see what annual additional kWh I can expect to see if my excess kWh will cover. At this moment, I keep the thermostat at 65-78 (heat on if drops below 65, AC on if above 78)...

Trying to decide if it is worth going from standard HVAC system to heat pump. I'm based in Northern California where temps are mild. Winter mornings hit in low 30s and summer temps hit highs in high 90s low 100s. With that said, I just got PTO on a a 12kW system with 2 Powerwalls in October...

On October 21, I switched my settings from Self-Powered to Time-Based Control. So just looking at the last 3 weeks of data, this week still with 2 more days left I get the following table: Oct 10 -16 Solar Generated: 294.8kWh Home Usage: 156.6kWh PowerWall Discharge: 72.9kWh Net Grid Use...

I switched to TBC and trying to figure out what % split I should be using for backup vs time-based control. Also, how does the system work compared to Self-Powered? When I switched to TBC, it looks like all the PV was sent straight to the battery and whatever the house needed, it pulls it from...

Thank you so much for this detailed response. Because I have an oversized system at the moment, I expect to be a net exporter come my annual true up. Since my PTO date of October 7 through October 20, per PG&E's Energy Usage Report, it shows a credit of ~304kWh and a monetary credit of ~$83...

Thank you for this breakdown. So is the end goal to import enough by year end to offset the MDC? What if you are importing more? Yes you will get a "payout" but it is at a fraction of what it should be so you are better off having it consumed right? Since PTO, it shows that I am exporting an...

I got PTO activated last week and since turning it on, I've just monitoring our usage pattern. Setup is 12kW System + 2 PW. Tesla settings is self-powered mode with 80/20 reserve split. Average house consumption is ~18.7kWh with solar being ~37.2kWh (28% to home, 25% to PW, 47% to grid). My...

Ok well I flipped the 4 bar at the main panel and it disconnected from the grid but I was expecting Solar to be generating still and not just discharge from the batteries the entire time. So I flipped the connect back on and now I have a connection to the grid but no solar production?

Going to be a dumb question but which one is the main breaker? I'm going out of town for the weekend and I know with solar and battery it can run 100% off grid. The installers took breakers from the main panel and installed a new 200A box inside the garage but they never explained anything...

So I checked my PG&E usage stats on 9/14, the day the installers finished, and was surprised that PG&E is already providing me credits? Take a look at the attached screenshot. At 11:00 AM that day, the installers shut my power off to do the load transfer for the whole home backup. The power...

If I disconnect from the grid through the main breaker, does that address the 65hz issue referenced or is that only the case when you disconnect through the app?

Thanks all again for your feedback. My system included a "whole home backup" where they installed what looks like a 2nd 200A panel? Regardless, I tested the "Disconnect from Grid" in the Tesla app just now and then went around the house checking each room to see if there was something not...

I sent an e-mail to the company I'm in contract with regarding my system. See my e-mail and response from them below. Would this holdup should I need to go after my solar company in case PG&E takes any action or something comes from this? Thoughts? My E-mail Their Response

I appreciate your feedback and commentary. I'll re-read the contract I signed with the solar company and see if I can see anything. If it comes down to needing to go off grid, I can do it virtually through the Tesla app it looks like. My system is oversized so I think I'll have enough solar...

At the end of the day, the installers configured and setup everything and said I can use the system live. They are the "experts" so I'm just following what they told me, because I questioned them about what the app was showing me, which was, it is showing power going back to the grid from my...

The settings I have right now under Powerwall is I have it set for Self-Powered with backup reserve set at 0% (just for tonight) and then I only have "Grid Charging" under Advanced Options which it says it is Restricted and said its configured by the installer. How do I make it so if there is...

This makes sense. I shouldn't be under this setting then because I don't have PTO so I'm not getting any kind of credits right? Should I be staying in Self-Powered Operational Mode and then change back to Time-Based Control after I get PTO?

Installers wrapped up their install today. I didn't go through Tesla, but went through a local installer and got a 12 kw system with 2 Powerwalls. Within about 30 minutes of the installer commissioning the system, I got an e-mail from Tesla about my powerwalls and then was able to see it in my...

Pretty annoyed at the install process. Install date was scheduled August 30 and 31. On August 31, installers installed all 30 panels on the roof and 2 powerwall batteries, but say they won't be able to complete the install because they didn't have all the parts. They schedule September 7 as...

While the install started last Tuesday, August 30, the installer's truck got into an accident and they weren't able to complete the installation the next day. They come back Wednesday this week to finish the install and hopefully turn the system on. It is 12kW with 2 Powerwalls. With that...

If I've done this right, taking usage data from 15:00 - 23:45 (3:00 PM - 11:45 PM) then on average I'm looking at something like this from the last 4 months of data which was high AC use. I try to keep AC off during these times. June is likely when I was actually running AC during peak periods...

How many PW you have? I'm going to have 2 PW. That should be sufficient to run off battery from 3:00 PM - 12:00 AM right? I guess once I get the system live I can see how long the PW batteries will last me. It'd be great if I could last from 3:00 PM to the next day when the PV system starts...

Installation on my system is scheduled for next Tuesday and excited about the process. Will be getting a 12kW system with 2 Powerwalls. Today, I have an EV vehicle and currently on EV2-A plan which has: Off Peak: 12:00 AM - 3:00 PM Partial Peak: 3:00 PM - 4:00 PM and 9:00 PM - Midnight Peak...

This is a sigh of relief if true. I had moved into a new house last year and started the solar process right away. I ended up not moving forward because I had no idea what my usage was going to be in the new house so I deferred doing solar until a few months ago. I was stressing out because I...

Thanks all, I ended up getting my questions answered. They said that Santa Clara county code is making it next to impossible to install batteries these days. Code won't let you stack them anymore and if you want them in the garage then you have to have other hardware I believe like smoke...

It shows 18,213 per PVWatts and they are saying that PV production will be 16,536.

Do we know if the IQ8 inverters will allow charging of the batteries from the solar system when there is an outage of the grid? It looks as though with IQ7, when the grid was down, the solar system was down too and wouldn't generate anything even if sun was up?

I took some time to create my follow-up questions on their design. Anything else I'm missing? Why is the goal set for 24,500 kWh? Why is there a note saying shading issue due to roof, obstructions, trees and chimney when its a 2 story house with no tree obstruction. How many electrical panels...

They did a site visit and that is the design they gave me to review/approve.

The calculations come from estimated 8,300kWh for the year. Then added an additional 2,500 kWh once I get solar (I explained to them that my 8,300kWh usage was conservative as I rarely ran AC to be cautious of costs, etc. Then added an additional 3,000kWh for 2nd EV. That brought total future...

I just received my system design and I'm a little surprised but I'm no expert. Can I get a look over by the group here? It looks like they are doing 30 panels, 30 microinverters and 2 Powerwalls to create a 12kW system size, estimating 16,536kWh annual consumption. I don't know why they are...

I'll be getting a 12kW system with 2 Powerwalls. I am currently on PG&E's EV2-A plan and I believe they'll shift me to a TOU plan correct? My question hopefully is simple If I put 5kWh back to the grid on non-peak hours and consume 5kWh from the grid during peak hours, do I still need to pay...

I believe I am going to move forward with a local installer. They quoted a 12kW system (30 400W Panasonic panels with IQ8M microinverters) and 2 power walls for $7K more than what Tesla quoted their 12kW system and 2 power walls. Based upon my research/reviews of this company, they seem to be...

Who did you end up going with if you don't mind. It looks like we are looking for the same thing. I have quotes for 10.4kW system with 2 Powerwalls. The short list for me is NRG Clean Power and Solar Optimum. Both are REC or Panasonic 400W panels with Enphase IQ8M microinverters. It seems...

I appreciate everyone's feedback here. Yes, the numbers I'm giving you is comparing apples-to-applies of solar with 2 power walls. The only difference is Tesla is 12kW system and the local is 10.2kW. It seems as though even with the 22% tax credit and NEM 3 risk being highly likely, the Tesla...

Looking to go solar. I have local installers who has provided quotes for a ~10.2kW system. They are using LG Neon R 425W panels, Enphase IQ8A microinverters and Tesla Powerwalls (on backorder). They've quoted me at $69K (pre tax credit) and have guaranteed that they would be able to get...

I think this will be an anomaly which will happen every now and then. I don't expect my usage to be like this month over month.

So I told the guy that the usage that I have is me being "conservative" on running the heater/AC as I heard horror stories of $500-$600 PG&E bills. I was also still new in the house, so for the majority of the months, I was "feeling out" how much use would correlate to the bill. So while those...

I met with a solar contact today and this is the table they came up with to say they think a 10.28kW system would be sufficient to cover current and future needs Current Usage Projected Future Use Month Current Usage System Size Additional Usage Future EV Total System Size...

Based upon the data points below, how much oversizing of the system should I do to account for another EV in 3-5 years (10K miles/year) and slight increase in use of heater/AC? Should I add/get Powerwalls? If yes, why and how many would you recommend? Total kWh/mo - January 605 - February 644...

In the 3 years I've owned my Tesla, I've only charged it at Midnight onward so AC is never running in parallel to the car charging. I thought most charge their Tesla using the grid during off-peak hours instead of using solar/batteries? I definitely don't want to add more panels later on. I'm...

Perhaps a dumb questions, but why the bigger system and 3 powerwalls? My monthly usage was - January 605 - February 644 - March 603 - April 660 - May 815 - June 976 (as of 6/28) If I were to assume 8 months to be 650kWh and 4 months to be 1000kWh, it'd be 9,200kWh/year. How much would...

I'm hoping to get solar on the house before NEM 3.0 and the tax credit reduces to 22% I have less than a year of energy usage in the new house but in the last few months, with this heat, I've been running the AC at "free will" more often than not. I have 1 Tesla vehicle which I charge maybe...

I know I am going to regret this but I am listing my fully loaded, phantom black pearl manual 2010 R8 V10 that has just under 24,000 miles for $100K. The car has a carbon fiber steering wheel, RS front grille, HRE P47 20" wheels with plenty of tread, and Fabspeed valved exhaust that you can...

Thanks! Gen 2 cable!

Pretty straight forward, looking for NEMA 14-50 Adapter

For some of the other cars I own, there are dedicated picture threads for specific colors so that one is able to get an idea for some of the mods others have done (e.g. wraps, tints, wheels, suspension, etc.) Since I now own a beautiful 2020 pearl white Model 3 performance, wanted to see what...

I took delivery of my Tesla yesterday and I am fairly anal about my cars but I am also aware that these reps have hundreds of deliveries they need to go to each day. I didn't want them sitting around while I go over every single spec of the car. The only major flaw I saw during my quick look...
