If a solar photovoltaic panel produces 1,000 watts of electrical energy and is active for 12 hours each day, how many kWh of electricity will be produced in a week?

Answer :

Final answer:

A solar photovoltaic panel producing 1,000 watts, when active for 12 hours daily, generates 84 kilowatt-hours (kWh) of electricity in one week.

Explanation:

The student's question pertains to the calculation of electrical energy output from a solar photovoltaic panel over a certain time period. Given the panel produces 1,000 watts (or 1 kilowatt) and is active for 12 hours a day, the daily energy output in kilowatt-hours (kWh) can be calculated by multiplying the power rating (in kilowatts) by the number of hours of operation. Since there are 7 days in a week, we simply multiply the daily output by 7 to find the weekly production.

Calculation:

1,000 watts = 1 kW (since 1 kilowatt = 1,000 watts)

Daily energy production = 1 kW * 12 hours = 12 kWh

Weekly energy production = 12 kWh/day * 7 days = 84 kWh

Answer;

=84 kwh

Explanation;

Electrical energy = 1000 watts

1000 watt = 1 kilo watt

1 week = 7 days

Number of hours = 7 × 12× = 84 hours

Consumption

= 1 kw × 84 hours

= 84 kwh
