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. Multiply the hours used on the average day by the wattage listed below. This will give you the watt-hours consumed per day.
Remember that some items, such as garage door openers, are used only for a fraction of an hour or minute 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 is given, the lower figure often denotes a technologically newer and more efficient model. The letters “NA” denotes 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. 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. |
