Here’s the equation: (total number of watts) x (total number of hours) = watt-hours. So, if you have a 60W bulb and you’re trying to calculate how many watts your bulb uses in 24 hours, your equation would read 60 watts x 24 hours = 1440 watt-hours. Or, to use the abbreviated measurement, the answer would be 1440Wh.
How many Wh does a house need?
Divide your average hourly wattage requirement by the number of daily peak sunlight hours for your area. This gives you the amount of energy your panels need to produce every hour. So the average U.S. home (900 kWh/month) in an area that gets five peak sunlight hours per day would need 6,000 watts.
How do I calculate how much power I need?
Multiply the unit’s wattage by the number of hours you use it (this will give you a certain amount of “watt-hours”). For example, if you use a 120-watt television for two hours per day. You can multiply the wattage by the number of hours used per day to obtain 240 watt-hours per day.
