CFE Meter for Solar


Recommended Posts

More or less.  One number is the number of KwH house is taking from the electrical grid.  Other number is the number of KwH going back to the electrical grid.  Your panels generate more than the second number but it got used  up to run your house.  Yes this is simple but understandable. The bill is a combination of both numbers.

KwH means Kilowatt hours or volume of electricity being measured.

The 1.8 reading is your net consumption from CFE when you are using more than you generate.   The 2.8 is the opposite.   2.8 reading - 1.8 reading is the running difference of your shortage or excess.  If your 1.8 is more than your 2.8 at the end of the bimester, they'll bill you.

And the minimum billing is 49 pesos, even if at 0 net use and making credits.      This is why sizing systems to average into the "sweet spot" of the CFE rate structure at lakeside, is the most cost effective way to go.    About 150 to 200 kWh net use, in 60 days, (3 to 4 per day used) keeps you at bills of about the same in pesos....150 to 200.

Does not pay to add 2 extra panels to get to "0".    Of course, many people still like to!   😉
