How do you calculate electrical work?
So if 1 watt = 1 joule per second, it therefore follows that: 1 Joule of energy = 1 watt over one unit of time, that is: Work equals Power multiplied by Time, (V*I*t joules). So electrical energy (the work done) is obtained by multiplying power by the time in seconds that the charge (in the form of a current) flows.
What is electrical work done?
So electrical energy (the work done) is obtained by multiplying power by the time in seconds that the charge (in the form of a current) flows. Thus units of electrical energy depend on the units used for electric power and time.
What kw do I need for my house?
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.
