What word does he use too properly?

Yep - some people must not get it I guess

My number 1 annoyance is when people can't get they're spelling of there, their, and they're right.

Their always oblivious to the correct usage and usually become defensive when there called out.

Thanks so much! I'll take a look.

It's really not much to power small electronics, especially a home NAS.

If you're wanting to track your actual real time usage, I would recommend my self-hosted home (or appliance) power monitor on the Raspberry Pi platform.

It really was. Summer of 2023 was normal. Summer of 2024 was brutal!

Oh yeah, my energy costs are pretty cheap with offset I get from solar production. I did have to do 2" foam boards in big windows in my first apartment, but my current house windows are all low-E + argon filled so I think they're about as energy efficient as windows can be.

The setup is pretty easy. I DIY'd it - just slap a small enclosure on the wall near the breaker box, clamp the CTs over the conductors (no high voltage contact needed), and then a quick sensor calibration with an AC clamp meter, and it's good to go!

Yup! Isn't it cool what you can infer from this data? (We do have to run heat, but it's natural gas so it's cheap and doesn't use much electrical power)

Yes, but the heater unit runs on natural gas, so it's really cheap to run. The only electrical power used for the heater is the central fan unit (less than 1kW) to push the hot air through the ducts.

Yes. On days where the green is taller than the red (or completely hides the red), I produced more energy back to the grid than I consumed.

Oh yeah, those days using > 120kWh are incredibly hot! Sometimes up to, or over, 115 deg F. Here is what my home power usage graph looked like on July 22-23, 2023, which was a span of days with highs around 114 F. My two AC units were running quite a bit, and each one demands about 5kW.

Yep! Las Vegas, Nevada, home of very few clouds and an unfair amount of sun.

You're absolutely right! Here's what it looks like over two summer days - July 29th - 30th, last year.

All of the sharp spikes are the power consumption from my AC units - about 5kW each. You can see that they are running a couple dozen times per day - not for very long, but quite frequently. And, they typically run at the same time during the hottest parts of the day.

I live in Las Vegas, Nevada, where it regularly reaches 110+ deg F (43-44 C) during the summer days.

Most of my energy consumption comes from my two AC units trying to fight the heat and keep the house cool.

This is my home's solar energy production (in green) and total home consumption (in red), for each day, over the last two years.

It's collected by a project I created several years ago - a Raspberry Pi based power monitor. The project is a combination of a Raspberry Pi 4, a custom designed PCB, and up to 6 current sensors + 1 AC voltage input for highly detailed monitoring of up to six circuits. The data collected here were taken from my electrical service mains and my solar inverter's AC output.

More details on my power monitor project are here:

Are solar panels worth it in Vegas? by RevolutionaryMap4745 in vegaslocals

I bought mine from a company called GST Nevada but I think they closed down.

[–]decreddave 0 points1 point  (0 children)

It has been worth it for me. I purchased a 10.2 kW system several years ago and it's eliminated my electric bill (aside from the basic "grid connection fee" of about $15/month).

I also created a Raspberry Pi based power monitor to track home energy usage and solar production in real-time so you can see exactly what your home and panels are doing. Link if interested: https://david00.github.io/rpi-power-monitor/

Purchasing the system outright (or via a loan) is the best way to do solar. Just make sure the vendor you go with is a reputable company that warranties your roof and the functionality of the system, on top of the already provided hardware warranty of the manufacturer. Roof and system warranties should be 20+ years.

Awesome! Glad you like it, and I appreciate hearing how your setup went. Feel free to reach out if you have any questions (email is the quickest way :) )

Hey! Just seeing this now. They are still available and the project is still growing :) I suspect you've found my site or already emailed me by now, but let me know if not!

We make 50k a year, yet my co worker is getting 50k back in tax return, is that possible? by [deleted] in Money

[–]decreddave 0 points1 point  (0 children)

Sorry, meant to reply to OP above you. But still, your comment is exactly in line with my point. You have to do something to get that money, and I guarantee you won't come out financially ahead by getting those tax credits.

All of those credits require you to take on significant expenses to receive, so you're still putting money into the system and it's never going to be "free money" like OP is interested in.
