    Screen re-boots every new trip

    For about the last month, the screen on my 2019 FSD Model 3 first freezes, then re-boots every morning, or after the car is parked for more than a couple hours. Tried the two button re-boot. I have a service appointment scheduled next week but could not help asking whether anyone else had this...

    Experience with fixing roof leaks

    I noted that after the recent storm blew through California I had a new leak. What I know: 1. Did not have it last year prior to install of solar panels. 2. It is in an area which might be where a rack was installed, but other than seeing that it leaked, there is no opportunity to inspect...

    Californians -- AB 1139 just got amended

    Looks like its now 20 years grandfathered. It also looks like for new installs the minimum credit has been changed from wholesale cost to some other, presumably higher number. Anyone following this closely?

    Data reset after PTO?

    So, a day or so after PTO on April 27, three months of “testing” data disappeared from the app. By that I mean the system was operational on Jan 27, so “lifetime” is now only the ten days or so. I sort of smiled when I saw that - “nope, nothing happened on this system prior to PTO, not that...

    Use Black Zigbee Gateway or not?

    Now that PTO was granted on my 16.32/3 PW system I was wondering the point of formally connecting the little black Zigbee gateway. Because I already had a Tesla Model 3 the app was live showing all my testing of the system from day one.

    Catwalk to rinse off panels?

    Because of my set up, and concrete tile roof, I am considering setting up a cat walk to rinse off every month or so. Its in SoCal, so there is more dirt than rain. Putting aside how building and safety might feel about it. It seems to me that a combination of the racking system which...

    Do you wash your panels? If so, how?

    The title says it all. I was considering getting a filter attachable to a hose to just hose em off every couple months. Thoughts?

    How to calculate savings

    Since savings and how to calculate them comes up quite a bit, I thought I would weigh in now that I see how my 16.32 system with 3 PWs works in reality. 1. Figure your annual energy usage and cost. In my case, pretty easy. Its 27,000 kwh. 3,000 sf house, southern cal, with two electric...

    Off Grid Test before PTO Solar + Powerwalls

    So, it seems the sequence for a safe off-grid test would be: 1. 3 Powerwalls installed at 25% capacity. 2. House is pulling about 40kwh a day. 3. 16.32 system probably will produce about that. 4. Step One: At around 8 a.m. turn on Powerwalls, -- based on what I have seen, they will begin...

    Ok, it’s on!

    Reason for new Main Panel?

    In my 16.32 three Powerwall install I just got the actual plans. They include upgrading the main panel from 150 amps to 200 amps. Now, when I look at the plans and diagrams, one wonders why? My guess is that one calculation, maybe two, are made. The first one would be how much...

    What Internet Connections do you need for Solar and PW?

    Ethernet or no? The system will be 16.32 with three PWs. I have seen mention of this in other threads, in my case the location of all the equipment is not very strong for the wifi, and I would think running an ethernet would be up to the homeowner.

    The Solar/Powerwall Checklist

    We will see how long this gets. :) From these boards and my own experience through somewhere in permitting on Los Angeles: 1. What is your usage? Its easy enough to get a year's worth of bills together if you have them. You will need to convert dollars into Kilowatt hours (Kwh) used. A...

    Has anyone noticed whether a layer of solar panels sucking up the sun makes the house cooler?

    Its seems as if it might. Many of the layouts posted are fairly close to covering every available square foot of roof.

    16:32 with 3 PWs in SoCal, Los Angeles DWP, what can I expect?

    I am now ready to dive in to the incredible knowledge, at least its incredible to me, of the posters on a technical level. Outside, on the side of the house, mostly shaded, where everything will go, is the meter and main panel. The main panel consists of one big red switch, according the the...

    How much do systems degrade? A friend's system seems like 33% in ten years.

    I am figuring out what size system to get. One worrying fact is that a good friend has a ten year old 7kwh system. At the moment, unless we are reading his bills incorrectly, its only producing 20kwh per day, in Southern California, mind you, when it should be more like 30kwh per day...

    Just trying to figure out the economics, thanks in advance

    I live in Los Angeles, so its LADWP. Big flat roof on a 2500 sft house. Based on a roughly $400 per month electric bill, Tesla recommended the 16.2 kw and four powerwalls. Here's the thing. Without the obvious knowledge I see on the boards here in terms of technical understanding and...

    What is the next step to FSD?

    I think its going to be stop signs and stoplights, which would mean autopilot could be used on any road, not just highways. I think it will be in increments. I think navigate on autopilot will go through a period of limitations. I think controlled and uncontrolled turns will be last. Do you...
