These figures are approximate representations. The actual power consumption of
your appliances may vary substantially from these figures. Check the power tags, or better yet,
measure the amperage draw with a clamp-on ammeter or plug in a Kill-a-Watt measuring device.
Multiply the hours used on the average day by the wattage listed below. This
will give you the watt hours consumed per day, which you can then plug into the load evaluation
form.
Remember that some items, such as garage door openers, are used only for a
fraction of an hour or minutes per day. A 300 watt item used for 5 minutes per day will only
consume 25 watt hours per day. Where a range of numbers are given, the lower figure often denotes a
technologically newer and more efficient model. The letters “NA” denote appliances which would
normally be powered by non-electric sources in a PV powered home.
We strongly suggest that you invest in a true RMS digital multimeter if you are
considering making your own power. Also helpful are clamp-on type ammeters and the Kill-a-Watt
meter. It actually makes sense to know where your power is being used, even if you are not
producing it, and if you are, these meters are essential diagnostic tools.
