Wattage/Voltage/Amperage calculator

This simple formula is used to figure out the amount of solar power needed from solar cells to supply an entire household-

Wattage=Voltage X Amperage ---or the proffesional notation of--- P=EI

Where : P= power
E=potential difference in Volts
I=is the current in Amperes

or- Wattage/Amps= Volts
or- Wattage/Volts= Amps

Then there is Watt hours wich is just amps (that is used by device) (x) the voltage used by the same device (x) the # of ours the same device was used . Kilowatt hour is 1,000 Watts. And 1 Horsepower(hp)= 746 Watts

And to get the totel household power needs you just add the Watt/Hours frome each device together for the household for the total power usage for a given period in time.

And to find out the size of the solar array that you need, you have to know the total expected power usage on the worst day for solar energy production, and include the amount of time during the night that there is no energy pruduction.
