    The 3rd meter is one I installed to measure what energy I export. basically it clocks up when consuming energy from the grid and counts down when exporting. Since the installation of the meter I've now installed an iBoost immersion heater controller that diverts any surplus energy that we do not use in to the immersion heater. When the immersion heater is up to temperature the surplus energy goes to out to the national grid.


    I used to log the readings in a long winded way as shown below, but have not decided to use the table above.

     

     

    I had our quarterly electric bill the other day (this was probably 2007ish), which asked for 136!!! Which I thought was far too high. Anyway after checking my meter reading I found it read less now than when it was read three months ago :o). Boy did I have a hard job explaining that to the electric company. I still ended up having to pay about 18 in standing charges :o(


    From 18th March 2007 - 19th March 2008 we have generated 2837.48kW of green power
    (Approx 7.77kW per day)

    Good energy charges from our bill dated 5th September 2008

    9th June 2008 actual meter reading 1583   (from energy suppliers meter)

    initially paying 12.64p/kWh
    then rose to 14.93p/kWh

    Standing charge was 13.04p/day
    then dropped to 12.53p/day

    All plus 5% VAT

    For the quarter we paid 36.83


    Good energy charges from our bill dated 6th June 2008

    1st April 2008 actual meter reading 1389  (from energy suppliers meter)

    paying 12.64p/kWh

    Standing charge 13.04p/day

    All plus 5% VAT

    For the quarter we paid 61.19


    Energy generated

    Initial reading 21st May 2008 3520units (from PV generation meter)
    Final reading 1st October 2008 4922.23units  (from PV generation meter)
    Total green units generated @09p/kWh = 1402.23 kWh = credit payment to us = 126.20

    Meter reading @ 22nd August 2011

    PV generation meter - 13,084kWh
    Energy suppliers meter - 00072 kWh - We had our meter changed to one that did not run backwards, a very big bummer! So we don't get any credits for juice fed back in to the grid. Last reading of old meter 6756 kWh

    1,874 kWh generated since 17th March 2011
    1,494 kWh used from the grid


     
    Meter reading @ 7th September 2011

    1,874 kWh generated since 17th March 2011
    1,494 kWh used from the grid - remember no credits for exports :o(


    Meter reading @ 7th March 2012

    PV generation meter - 14,053 kWh
    Energy suppliers meter - 01159 kWh -

    remember no credits for exports :o(

    I have now obtained another meter (not installed yet) so hopefully soon I'll be able to accurately calculate the import/export of energy.
