WOW!!!! We have a three story with three refrigerators. Yes, we purchsed literally everhing that was available using inverter technology. Every lightbulb is LED, and we are here full time. We don't have solar or use our AC units. We also have a large lap pool.

Our comsumption on the June bill for two months was 1140 KWH. Sounds like there is a problem in yous system.

Yeah, same. LEDs, almost every major appliance is inverter. I probably have a bit more stuff than you, so I would expect maybe 1600-1800 Kwh per billing period.

There is either a leak to ground someplace, or the meter is not only failing to record my solar production, but also reading my consumption high.

Wouldn't it be ironic if the meter was damaged by CFEs poor quality electricity?

I am currently experiencing the very same thing with my system installed back in February. Installed solar, got the lowest bill ever. Woohoo! Next billing cycle, the highest bill ever.

From March 2022 to November 2022 my CFE bills totalled M$1,632. During that time I was having a carriage house built with all of the use of electricity associated with that and for much of that time the house was occupied.

Then in February 2023 the CFE bill was more than for the entire 10 months in 2022.

In April 2023 the CFE bill was M$6,993!!

Six months into the year, my CFE billing has been M$13,014 on my behalf. That is over three times as much as was paid for the full 12 months in 2022. At this rate, my 2023 CFE cost would be over M$26,000 instead of the M$4,138.24 that I paid in 2022, or 600% more.

And my solar system has produced over 2,200 kWh of energy.

I'm seeing very much the same pattern. My last bill was for M$7300. I've started tracking daily usage and production and entering it into a spreadsheet to calculate what I should be getting billed for. In the year prior to installing the solar, they billed me for an average 1825kwh per billing period. The peak was 2376kwh, which, like you, was during construction.

The building was completed in late January, and the panels came online mid-February; the February/March bill was for 738kwh. Then the April/May bill ballooned to 2786kwh!

Based on a month's worth of daily readings, my usage per billing period should be around 2250kwh--which still seems a little high--but then reduced by the approximately 1900kwh of panel production over the same period. So I should be seeing bills for approximately 350kwh, not almost 3Mwh.

So, have you been able to resolve that with CFE? Did they credit you for the meter error?

We haven't had that, but once we had the wine cooler decide to start drinking electricity instead of wine, and another time there was a short on one of our water pumps. We never would have caught either thing if we hadn't recorded the readings weekly.

In California (thankfully haven't lived there in a number of years) they eliminated the requirement for electric companies to pay you for excess energy produced.

The utilities will still need to pay for electricity generated by their customers with solar panels. However, the incentives have been greatly reduced. The utilities have complained for many years that they have been paying too much for energy generated by their customers.

Have you considered getting a photovoltaic system? We have one here in Montana. Our monthly bill is $4.20, the connection charge to Northwestern Electric. We put more back into their system than we take out at night or in the winter.

Yes, to reduce my impact on global warming I had solar installed several years ago. I assume that your system, like mine, is connected to the grid. So I feed high quality electricity into the CFE grid and I get poor quality electricity back from CFE.

Most of the time I give CFE more than I consume, resulting in bills of M$69. But then the CFE meter stops working properly. CFE charges me for consumption, but doesn’t credit me for production, and I get bills for thousands of pesos.

I am currently experiencing the very same thing with my system installed back in February. Installed solar, got the lowest bill ever. Woohoo! Next billing cycle, the highest bill ever. I've been going crazy trying to figure this out, and the only numbers that even come close to making the math work is adding production and consumption. Then billing at "bigger carbon footprint than a US military base" rates. Currently entering week 2 of waiting for a CFE tech to show up.
Your post has restored my sanity...thank you.

I’m wondering whether anyone on the board has any experiences about using Starlink to report.

Currently, I have MegaCable in Troncones. I have two accommodations in separate buildings on one property and I want to have separate NATs for each accommodation.

MegaCable won’t sell me a second service as I have one CFE account. MegaCable says I would need to have a second CFE meter before MegaCable would permit me a second MegaCable service.

I understand that people in Troncones report problems with reliable Infinitum internet.

If people are having good experience with Starlink being fast and reliable, I’m thinking I could get Starlink, then run it through two routers and get two NATs that way.

I recently asked about Starlink at Serccomex. Isidro is of the opinion that it is not ready for the beach areas, still too sensitive to weather.
As is mentioned downthread, it will improve as more satellites go up.

Starlink looks like it could work in our situation once it is beach-worthy.

Have you contacted CFE? They offer internet service.

I think their internet comes by cellular signal, no?

The cellular service in Troncones is variable. My place is in one of the effectively-unserved areas.

But if CFE’s wifi service is comparable to CFE’s electric service in Troncones I would pass.

CFE electricity outages are frequent. By that I mean anywhere from several times a week to several times a day. And we know that that kind of cycling is bad for electronic devices.

In addition, the dirtiness of the electricity is shocking. (Pun not intended). I have had < 60 volts coming in at times and over 150 volts coming through at other times; the sine waves go wonky; etc.

Imagine what all of that does to televisions, refrigerators, audio systems, modems, routers, etc.

If CFE were to become a reliable seller to me of a supply of its core product, electricity, that doesn’t damage my interests, maybe I would consider rewarding it with more business. But it fails that test.
