Reading my power bill
How much electricity do you use? 


Your electricity bills contain important information that will be used during the consultation to help define the best system for you.  When considering a solar battery system we suggest finding a couple of electricity bills from the most recent summer and winter periods.


The most critical information are the electricity tariffs you get charged, the periods these tariffs apply, your average daily usage and how your usage varies between seasons.  

The other critical question we'll ask is what proportion of your daily consumption is used during the day and how much is used at night.




What do the terms on my bill mean?


Average daily usage: The amount of electricity used, on average, each day during the billing period. This is a critical measure and forms the basis for sizing your solar storage system.  It is measured in kilowatt hours (kWh).


kWh: Electricity consumption is measured in kilowatt hours, which is a measure of power use for a given period. For example a kilowatt (kW) is 1000 Watts of electrical power, and if a 1000 Watt appliance runs for 1 hour it consumes 1000Wh or 1kWh.


Average cost per day: The average amount paid for electricity during this billing period.


Charge/kWh: Electricity consumption is priced in cents per kilowatt hour.  For example, $0.29/kWh or 29 cents per kilowatt-hour (c/kWh). Thus if you use 20kWh each day, it would cost $5.80 each day. Remember to add gst to the cost by multiplying by 1.1. Often gst is added at the end of your bill


Peak and off-peak: Refers to times of high (peak) or low (off-peak) electricity consumption within the community. A flexible pricing or time-of-use electricity plan will have different rates or tariffs with different charges for peak and off-peak use.


Service to Property: A fixed charge that is also called the 'connection charge' or 'daily supply charge'.
