ManxMan Posted July 15, 2020 Report Share Posted July 15, 2020 Our landlady put solar on our house. I went and read the new meter CFE installed and I get two numbers (the old meter just had one). Today it read 50 then 75. Does anybody know what that meter is doing and how I can track my usage? Quote Link to comment Share on other sites More sharing options...
Mostlylost Posted July 15, 2020 Report Share Posted July 15, 2020 The meter reads the number of KW received from CFE and then the number of KW sent to CFE from your cells. You subtract the sent from the received to see your net purchase of KW from CFE. 1 Quote Link to comment Share on other sites More sharing options...
lcscats Posted July 15, 2020 Report Share Posted July 15, 2020 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. 1 Quote Link to comment Share on other sites More sharing options...
tkessler Posted July 15, 2020 Report Share Posted July 15, 2020 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. 1 1 Quote Link to comment Share on other sites More sharing options...

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! 😉 2 Quote Link to comment Share on other sites More sharing options...
