Question: How many 80 watt solar panels to run a house?
Answer: Determining how many 80-watt solar panels needed to run a house requires some simple calculations before purchasing the solar panels. First, determine the amount of electricity that is used each month to power the house. Reviewing a monthly electricity bill from previous months can give a good estimate on the approximate amount of kilowatt-hours that are used.
Example: 600 kilowatts of electricity is used each month. There are approximately 1000 watts of electricity in 1 kilowatt of power. To determine the monthly watts used, multiply the number of kilowatts by 1000 watts. In the example above, the approximate usage is 600,000 watts each month.
To find out how many 80-watt solar panels needed to run a house, simply divide the 600,000 watts needed by 80 watts for each solar panel to determinate the approximate number of panels needed.
Example: 600,000 watts / 80-watt panels = 7500 solar panels
This calculation proves that 7500 solar panels that are 80 watts each will provide enough solar power for a house that uses 600 kilowatts of power each month. The solar generated electricity is stored in a battery cell ready for use each day.
