Charts of energy usage for 2003 and 2004. Electricity usage data is for metered kWh's. Imported electricity is lower in 2004 because PV generated electricity consumed by the house is not metered and therefore not recorded on import meter.

2004 Stats - up to Nov 2004 the system generated far more per week than we were importing (weekly average amount imported = 17 kWh)

total generated in 2004 = 1479 kWhrs from March 3rd.

Best week = 61 kWhrs ... Best day = 11 kWhrs
