A young engineer is building a solar PV system for his farm located in an island where the peak sun hours is 5 hours per day. He has purchased 10 solar panels and each solar panel has a rated power of 300 W and an area of 1.8 m2. The system efficiency is 60%, A. Estimate the monthly electrical energy output B. Calculate the monthly capacity factor. C. If his actual electrical energy requirement per month is 540 kw-hr, how many more PV panels does he need to add?

. Discuss how renewable energy systems will bring benefit to the people living in the chosen area.

A noninductive heater element with a resistance of 5 2 is connected across a 60 Hz source. The supply has a sine wave voltage with an instantaneous maximum value of 141.4 V. a. Determine the power in watts taken by the heater unit. b. What is the energy, in kilowatt-hours, taken by the heater unit in one month if it is operated 5 hours per day for a period of 20 days?

A. In the morning, the student plugs in a computer (240 W) to study physics, a microwave (800 W) to make breakfast, and a hair dryer (1200 W) to dry the hair. What is the overall current in this student's room, in Ampere?   B. A circuit in a student’s room has a 15 A circuit breaker. In the morning, the student plugs in a computer (240 W) to study physics, a microwave (800 W) to make breakfast, and a hair dryer (1200 W) to dry the hair. Will this be enough to trip the circuit breaker?     not enough information     no, because the overall current is more than 15 A     no, because the overall current is less than 15 A     yes, because the overall current is less than 15 A     yes, because the overall current is more than 15 A
