It is! You have to dig in to understand what you're reading. that's for sure. From the reference Bookings provided, their number only includes direct payments from G20 countries: Also funny how they rounded $584 down to $500. So, the Bookings number only accounts for a handful of countries...

An or proposition like that is known as a "sucker's choice" - it's this or that. Obviously, nuclear war is bad. Obviously, climate change is bad. Nuclear war may or may not happen. Climate change is well under way and +1.5C doesn't seem stoppable.

Ran some numbers on SAM to see what the benefits were mathematically, here are the results for a 7.6 kW array at latitude (25N) when compared to fixed flat (laying on the ground). Seasonal Tilt: 13,549 kWh, +12.8% Dual Axis: 17,761 kWh, +47.8% Tilt angle Fixed annual kWh, % increase 1 Axis...

Apologies my calculator skills are sub-par, that's why I try to show all the steps so those with more nimble fingers can do it correctly. But, the steps should be correct so you can calculate the efficiency for any gear combination. Now that you have DIY batteries...microinverters may not be a...

Get the Word out! I was talking to a relative yesterday about the migration away from fossil fuels. They were convinced it couldn't happen. Given HB741 passing, they might even be right. While I suspect that almost everyone is aware of the climate change issue these days, I don't think a lot...

Two year follow up report... So, rather than DIY I shelled out and purchased an EcoWitt Wittboy back in 2022. It's worked well and most importantly didn't die after it's first year as every outdoor weather station before it has. It's even still on it's first battery. AFAIK, the solar has...

A voltmeter won't cut it. It'll tell you the current state of charge, not battery health. Let me rephrase... take it to a well-equipped parts store in a big town where there are people that know what they're doing. Probably should call them and explain your issue and ask if they have a...

Thanks! I think most are. Not sure about the three listed as they use microbial action, but I want to believe. From the Renecle page: Reencle is NOT a Dehydrator NOR a Grinder Reencle operates on totally different and unique mechnism using microbial technology(ReencleMicrobe™) which makes it...

No WiFi? Needs a physical ethernet cable? What are they used for anyway? With SmartThings I send text messages to my cell phone to get alerts of things I need to take action on... what do you do to avoid the internet for those types of things?

That's odd.. mine has dozens of profiles. Possibly they have to be loaded remotely. You might try calling tech support to if they help you out in the interrim.

I might be a believer, but this sort of stunt sounds like it is driven more by climate hysterics. But, AFAIK there are no international laws to stop them from doing crazy things. In this instance, it doesn't sound concerning (sounds like the equivalent of a tenth of a snowflake in a blizzard...

Thanks for sharing your experiences! I hope you take some photos and blog about how it goes! Interesting! I thought some folks picked the IotaWatt over the Vue to have local hosting.

Don't have one, but according to the Amazon Q&A the bond bridge supports 303.2 MHz According to this, the Bond V2 now has an even a lower frequency range: 285.5 - 505.5 MHz, versus 300 - 450 MHz on Snowbird (V1?); so either should work. The V2 supports a local API: If you're 433 MHz, Sonoff...

If it's for emergency using cheaper lead acid is often more economical, see the Battery FAQ for how to compare $ of different chemistries. A natural gas generator with a sound shield would probably be a lot cheaper. But that "mobile" bit... Two Battleborn's will weigh in at ~60lbs. 200 Ah of...

Sounds like you're going to need to have them unfold or tow an array on a trailer. Either that or the compressor won't be able to run much. In order to answer how many AGM batteries you'll need to decide how much power you need (e.g., how frequently the compressor runs). You can do this with a...

I couldn't find your manual, but the manual for model 4210RN on page 22 had the maximum voltage as 92V and maximum input power at 24V is 800W. As your panel voltage is 41V, putting 3 in series would be to high (123V) for that model. That might be okay if your MPPT is 138V (Not a Tracer, but...

ref In the snippet below that should have been July 2020. Possibly held up with Covid or perhaps the trial revealed new flaws? ref

No one should care what I believe as I'm not an expert. They should look at observable facts and what experts who study the field say. Mainly, at this point in this thread, I just try to answer questions I think I can help with and post headlines to current news so people can stay up on what's...

I've seen a few members express concerns over threads that go off topic. What do you think and what would you like moderators to do about it if anything? Update Since starting this thread a number of issues have cropped up as to likes and dislikes. For example, we have members that: love the...

Sorry to be literal, I can think of three reasons, first is they honestly don't understand that different driving conditions affect mileage, secondly that they're being social and using that as a conversational ice breaker, sort of a "Think it'll rain today?" The last one is they've been hired...

No, it's not April 1st, but it seems like it should be. Was thinking about speed bumps while watching cars whiz past and wondered if anyone had turned it into a generator. Sure enough (ref): The average car is around 1500 kG, so extrapolating the curve that's about 2 kW per car per speed bump...

I wonder what the acronym is for a solar-powered EV? PVEV? SEV? WTF? The one to the right is supposed to get 40 miles per day from its PV cells and 1,000-mile range on its battery. The price is up to $33,200. Should be coming out this year. The cells are pretty interesting, they have to...

10" is unusually high even for here. I was watching myRadar and there was a narrow yellow curved continuous band that was pretty much centered over the house all day- it was like the cartoon where the cloud follows the cursed guy around. 5 miles south had 6" and 3 miles north 4" (weather...

How are we doing? It's an enormous challenge. Was looking at the climate action tracker, and it's depressing....basically, with the current policies & actions, the world might be at +2.7°C by the end of the century. Even in the "optimistic" scenario, we'll be at +1.8°C. We have <7 years to...

$11,600 BYD Seagull launches on April 18 with 305 km sodium-ion battery

I'm going to take back everything I said about flexible panels... the Renogy flexible panel warranty: 100W for 4.2 lbs that I could glue down somewhere and is 21% efficient at $1.89/W? This paves the way for a few more solar projects.... We sure do live in interesting times!
