That’s the quickest I’ve read. Usually 8-20 years.

Here's the problem with information. You NEVER get the whole story from ANYBODY. 

Now me, I'm safe. I'm a nobody

Payback... is questionable if you turn-key the project. If you are technical - and capable of doing some welding for mounting (not on the roof) payback is much more certain, with a lot of sweat equity. The KEY to a successful  and reliable solar or wind project is GROUNDING. Low impedance grounds protect people and equipment when lighting hits... i think you can be a lot more reliable with solar in storms than your local utility.. The solar systems also protect you from future carbon taxes.. and higher rates. Regulators, inverters, and panels are peanuts compared to what they were three or four years ago. It might be prudent to wait for costs to drop a bit more for hardware... but on the other hand more than half the project will be copper and labor.. and that is only going to go way up... i like the battery based independent off grid best... at some point we will have LiFEon batteries that will make you wonder why we built hundreds of thousands of miles of transmission lines everywhere....

It was a quicker buy back as I’m in Austin and their liberal policies were ridiculous with the rebates. I did the math and was surprised as well. They were really pushing rebates when I signed up and split the install over two years so I could maximize my return.

 

Austin energy policies still pay higher than most utilities across the US. I don’t agree with the policies but I’ve clearly benefited from them.

 

Btw I’ve had my panels installed for 10 years. Only in the last 18 months am I above water on the investment. Sun keeps shining so I’m enjoying my guaranteed returns!

Heat and hot water are the two biggest users and both can be obtained indirectly without batteries which I find the distasteful part of 'off grid' living using those methods. Solar and wind to be clear. 30 plus years ago we were building solar 'collectors' that heat water and supplement heating well enough to reduce energy cost to near nothing. But like always there wasn't any money in it for commercial profit and it wasn't totally independent for the consumer....so......

 

Greed kills everything it touches.

what manufactuer did you go with on your panels, and are the replacement parts off shelf replaceable , or is everything needed to operate solar utility have to be purchased directly from the installer? i'd like to build a set up for a small rv park in Arizona but dont want to beholden to the installer for thier components.

It’s a ground mount in the backyard. Yeah putting on a roof seemed stupid.

it is foolish but in a city land is expensive so roof mount it only option. its also a good oportunity for Highschool drop outs to start a business in solar panel cleaning for homes, beats being a gardener

At the time I got to select from approved installers. I found a company that had reasonable rates as opposed to some of those tools who were clearly soaking folks. Once selected I worked with them on parts. Their markup was minimal but I had to use the approved installer for the rebates.

I went with standard polycrystalline panels 6x10 or 60 individual cells wired together. I also went with Enphase micro inverters and that’s proven to be a good choice. Only had one partially go bad in the whole time. You can observe individual panel performance via the web or directly if your not into opening your network. My setup just dumps into the grid. In the 10 years only been down for about 30 minutes. Rural or where you may have days without power obviously would drive that decision. Frankly a transfer switch with a generator makes more sense for those situations.

i only wish there was another way to store the generated energy besides batteries

There is. Dump it back into the grid. Some utilities pay handsomely others not so. If in a solar friendly region may work for you.

i was hoping someone would come up with a way to easily build a giant 2 ton flywheel under ground instead. but i guess one must utilize everything you can for storage.. batteries and gen set too, maybe hydrogen storage and electrolosys of gasses into a weather balloon as a fuel tank source

that's alright, there is plenty of unwanted land to bury them in, or some volcano or lava field to toss them in, Just don't tell the enviro's that.  I'm sure they can be ground up into something that help make some sort of road surface or something else.

Seems the manufacture of the hardware for these systems uses more fossil fuel that the sources they are meant to replace. That is a net larger carbon foot print. 

Damage done before you even fire it up.

      I wonder how much carbon is on all those high mileage valves?

      AFM Experience

      By Atlas · Posted

      When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007

      Bridgestone vs Goodyear tires?

      By Chuck FB · Posted

      I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.

      Seems to be Missing a lot of Updates

      By newdude · Posted

      Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features. OnStar and Wi-Fi may not work after remote start CarPlay may not automatically reconnect Part of the Driver Attention messaging screen may be in English even though the language is set to something else XM may not work After a dead 12V the radio may set to Arabic at each startup Bluetooth contacts might not be able to sync with the vehicle During an OTA the 12V battery may drain Customer might see a screen telling them to return to the dealer After changing the Wi-Fi SSID or password a device may not disconnect If a device is connected on the 2.4Ghz band, nothing will connect to the 5Ghz one, which could show as slow Wi-Fi speeds Customers might have noticed Wi-Fi dropping in certain areas and reconnecting later Customer might see the top of the screen blinking during Android Auto Android Auto may not connect CarPlay audio might momentarily cut out The "Add Phone" button may be grayed out The radio may not start up   V167 Most Notable Improvements:   Outside Air Temperature is incorrect. -You may see a popup message for Engine Shift. (Corvette Only) After changing the exhaust sound they get a popup that "mode change not applied", even though it was. -When changing volume, the volume bar is for Traffic instead of Audio. -(Corvette Only) Improvements to the placement of buttons and text. -If the customer receives the message "Apple CarPlay Could not connect", the cursor might move in the opposite direction than expected when using the control knob. -Android Auto automatically starts playing their music, even though they have turned that off in settings. -Intermittently they have a red OnStar LED with no OnStar function and/or no audio. -The minimum length of the Wi-Fi password was increased to 12 characters. -The popup message "Driver Attention Check, check your mirrors or Super Cruise will shut down" may not have come up on the display when it should have. -Startup animation added for 20th anniversary of the V-Series on Cadillacs. -The Navigation app received location improvements when going under long underpasses. -In the Navigation app there are filters for charging points that the vehicle cannot use.   V164 Most Notable Improvements Most notable improvements contained in this release may include: Apps Intermittently, an “SD Card Removed” message will pop up in the Navigation app. While in the audio app, the radio may stop working. Trailer Tire Pressure sensors may not be learned in the Trailer app. Not being able to return to the home screen while in the Camera app. After an ignition cycle, the radio might go to a black screen or stop working if using Sirius XM. Spotify icon truncated on Audio app.   SXM When changing power modes with the ignition switch, the HVAC pop up might appear. During startup, the radio will show the brand splash screen then go blank. Receiving a confirmation pop-up when changing drive modes. A “Return to Dealer” message may appear on the radio screen. SuperCruise setting toggle may not work. System After an ignition cycle, the radio might go black or stop working if using Sirius XM (SXM). Settings When performing a factory reset, the radio may stop working. After performing a factory reset, the radio may stop working when trying to switch users. When trying to go into the Language section quickly after startup, the radio may stop working. Projection Wireless CarPlay cannot be connected after unpairing another wireless Android Auto device. When the Android Auto screen comes up to connect wirelessly, the screen may freeze if the Cancel button is pressed. Removed the Apple CarPlay Cannot Connect screen when a device fails to pair during the autoconnect process. CarPlay information may not show up in the audio app. Near Field Communications (NFC) chime may be heard when NFC does not work. The Cannot Connect screen does not pop up after the first connection on wireless CarPlay fails. Apple CarPlay is now functional in Guam. Over the Air (OTA) When a software update is cancelled, the downloading logo may still be displayed. Energy When using the Energy app, the radio may stop working. When plugging in the vehicle, the display might show “Now” instead of “Charging Upon Plug In.” Instrument Cluster Voice recognition can be started while on an OnStar or phone call. When downloading contacts, there is a progress bar and circles on the Recents page of the cluster. The temperature on the cluster and the display may be different. After receiving and ending a call on the secondary paired phone, the cluster may get stuck on the phone menu. Bluetooth Intermittent Bluetooth connection loss.
