I am renting, so solar is not an option for me. But I sure would if I owned the house.
My neighbors all pay $200 - $400 pesos per CFE bill. I pay $3200 - $3800 pesos per bill.
For my work (world-wide, based out of Hong Kong) I need two desktop computers running 24 hours a day, 7 days per week.
Normally, this would not cost as much as it does, but when they built this house, they used extremely small gauge wires.
This causes the wires to heat up building up resistance and requiring a stronger draw of current than a properly wired house.
The entire house from the meter to the breaker box and throughout the entire house is wired with 20 gauge wire, and should be wired with at least 14 gauge wire, and preferably 10 gauge wire. There is thicker wire in the cord of my night stand reading lamp than running in my house!
The people who built the house only received a one-time lump savings of about $25 USD by going with the lowest gauge electric wire they could. But, costs me over $100 USD per month.
My electrician said because of the size of my bill, CFE would be required to put in a 2nd meter for just the computers, even without changing the gauge of my wires if I demanded it... and that would save a ton of money. (I laughed, because CFE does not respond to demands.) I would have to separate the lines from the existing line and have them ready to be plugged into a new circuit breaker (which costs a ton of money) have lines running from there to the new meter and of course, pay CFE for he new meter (a lot of money).
Paying to fixing up somebody else's house is not on my list of things to do. I will be moving soon. Two of the houses I have considered are solar and not only have $99 peso CFE bills (with pool pumps and Jacuzzi) they are also properly wired to accommodate people who use more than just an incandescent bulb hanging from a couple of wires dangling from the ceiling in the bedroom from 20 gauge wires. Viva Mexico!
