Solar Panels in San Felipe?
I am curious if anyone has installed a solar system on a CFE electrified house?
Since I don't live in mi casa fulltime, I got to thinking maybe I could rack up enough credits, while I'm not there, to help offset my electric bill?
So I am curious if anyone else has done this?
If so
1. Did you have to setup the system with another meter from CFE
2. Can it be done without the knowledge of CFE? In other words, make the meter run backwards?
3. What is the exchange rate? Kw to Kw or are there transfer costs involved.

...............Yes
Since I don't live in mi casa fulltime, I got to thinking maybe I could rack up enough credits, while I'm not there, to help offset my electric bill?
.................Pretty much, yes
So I am curious if anyone else has done this?
..............In the process
If so
1. Did you have to setup the system with another meter from CFE
............CFE replaces your meter with a so-called "smart meter"
2. Can it be done without the knowledge of CFE? In other words, make the meter run backwards?
.............NO, CFE has to sign off on the install, the new meter " runs backwards" and gets credits to your account
3. What is the exchange rate? Kw to Kw or are there transfer costs involved.
..............CFE charges you about 65 pesos per billing cycle for a connect fee
A friend here in Ensenada had 3000 peso CFE bills, installed a 1500 watt system (about $4500.00USD) and her bills are just the connect fee for the
last several billing cycles.
Your installer works with CFE to get all the paperwork done and signed off

The Baja Batteries people (across from the El Dorado Pemex) have done a few grid tie installs (on their building, and some residences around San Felipe).
When I looked into it a few years ago the economics didn't work out for me. I'm in San Felipe mostly in the winter, when the electric cost is highest
(with electric heating), and away in the summer, when the amount paid for electric is the lowest, plus there was a high fixed monthly cost for the new
meter. Too low a return on the substantial (5 figure) investment needed.
If the summer electric subsidy comes down (so that the price paid is higher), or the fixed meter cost is or becomes lower, it could be worth looking
at again.

This is a Post from my Facebook Baja South Campos Amigo
The Name of the man who did this to his home is Joe Jones
We have just completed our first month of operation of a “Grid-Tie” Solar installation at our home in San Matias. San Matias is about 35 miles west of
the Military checkpoint, on the road to Ensenada. We purchased a lot here when we decided to live full time in Mexico, but since our home south of San
Felipe did not have commercial power wanted somewhere in Mexico where we could live cheaply and have commercial power in the summer for cooling.
We have loved the decision to have our place in San Matias. While only 100 miles from our home on the beach it has a completely different atmosphere
for living. Though only 2,800 in elevation the added elevation and the 35 miles from the Sea of Cortez results in lower temperatures and very low
humidity most of the time. Water you can drink from the facet at $12 dollars per month, power provided by CFE, Telnor telephone and soil that is great
for gardening made for a great place to spend the summer. And great Mexican neighbors, part of a small Mexican village (with a number of us “Gringos”
also around) made for a very enjoyable and different environment than the beach community.
We also loved the electric bills for the first 8 to 10 months we lived here. The electric bill, which comes every other month, is the only piece of
mail we ever receive in our mailbox. (Mailbox required by CFE for them to deliver the electric bill.) Most of the time the bill was in the $30 to $40
per month range, sometime going to $60 or $70, but very affordable. Then it went up like a sky rocket. The two month period ending August 10th was for
almost $8,000 Pesos.
After a little research, I discovered that electric bills in our area are really “subsidized” for low users of electricity. Many of the homes in San
Matias only have a single 110 volt connection to CFE instead of the 220 volt connection normally found in the US. If you use less than 3,000 kwh
(kilowatt hours) per year your electric rate is less than 1 peso per kwh. Go over that and you rate is over 4 pesos per kwh. Which is what caused the
initial low bills to jump so high once we reach the 3,000 kilowatt mark.
Since we were living like we would in the States‘, cooling, three refrigerators, freezers, electric dryer, washer, etc., we of course where soon over
the 3,000 kilowatt point after those first first few months. Since my neighbor and I in San Felipe had obtained a large number of used solar panels I
decided to look into a “Grid-Tie” solar system for San Matias. I was already running fully on solar at our beach home, and with my background as a
retired Electrical Engineer I decided to talk to CFE about it.
A “Grid-Tie” solar system is very similar to the system used at our beach home, but without the bother of needing to have and maintain batteries, the
only real re-occurring cost of a solar system. The system will generate power during the day, in fact our meter actually runs backwards most of the
time now during the day. Then at night, or when my wife is running the electric dryer, we take power from CFE. An ideal system would generate
sufficient power during the day so that the excess power would match what you use at night. End result, no electric bill.
CFE was very willing to work with me on this. They e-mailed me a draft copy of the required contract and a list of information they needed. I
completed that, e-mailed back to them. They checked it and I then went in and signed the contract. Only cost was a little of $100 for a new digital
meter, which they still haven’t installed. But what the heck, I don’t care, the analog meter still runs backwards just fine.
The system I installed consisted of twenty 185 watt solar panels and a 4.2 kw (kilowatt) inverter, with built in controllers and disconnect for the
solar panels. Only other requirements was framing for the solar panels, wire, and an electrical junction box to tie the 220 volt output from the
inverter to the commercial power. Since I used to be an Electrical Engineer, and am very handy I basically did the installation myself which does of
course save on the total cost of the system.
At $150 per panel I had $3,00 in panels, the inverter was $1,800, and I estimate I spent approximately $400 more on the wire, framing and junction
box. Total cost approximately $5,200.
After having the system in for the past month, I am generating an average of 20 kwh per day. About 1 kwh per panel. So in a one month period I have
generated just over 600 kwh for the month. At the 4.2 pesos per kwh I am paying for electricity that ends up reducing my electric bill by $2,520
pesos, or at 12 pesos per dollar, $210 per month. So in just over 2 years the system will have paid for itself and I will in essence be making over
$200 per month off my solar system.
Another second benefit will be that after a year of this I will be back below the 3,000 kwh per usage level and what remains of my electric bill
should be billed at the less than one peso per kwh rate. Looking good.
We deal with CFE out of Ensenada. Not sure if the San Felipe area has the same rate structure. But if it does, and you are experiencing high electric
bills you may want to consider installation of a Grid-Tie solar system for your home in San Felipe.
Will be very happy to discuss with anyone about this and provide additional information about “Grid-Tie” solar systems, or solar in general if you
would like. I can be contacted by e-mail at bajajoe@hughes. Net And just remember: “Life is Good”. Joe

And what stops his (summer) bills from coming down below 3,000 kwh before one year, I wonder? The system is already running.

The DAC (high usage rate) is reached by having an average consumption of 2500 kWh per month (on the 1F tariff in San Felipe, other areas are
different) over the past 12 months (a rolling average, updated every two months).
So if the consumption was well above that it'll take a while to wear off (6-8 months if was previously 5000 kWh/mo and is now zero, for example). I
agree it would generally reset before a year if the consumption has dropped a lot.
