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 ampere draw with an amp meter. Multiply the hours used on the average day by the watts per hour listed below. This will give you the watt hours consumed per day, which you can then plug into the load calculation. 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. The letters "NA" denote appliances which would normally be powered by non-electric sources in a PV powered home.
