To heat a room with dimensions width a=3 m, length b=5 m, height h=2,2 m, approximately an electrical power of P=10 W per square meter is needed. At a cost of 0.2 soles per kW.h, how much will it cost per day to use this heater?
Solar panels are rated by their theoretical maximum output capacity. A 2-kW PV panel would theoretically produce 2 kW of electricity at its maximum output (during peak solar radiance). If the average daily peak sun-hours in Philadelphia are approximately 4.0 hr and a rowhome is outfitted with 10 PV panels each having a capacity of 260 W, how much energy (kilowatt x hours) would be generated in one year (in units of kWh/year)?
At a certain location, the solar power per unit area reaching Earth’s surface is 200 W/m2, averaged over a 24-hour day. If the average power requirement in your home is 3 kW and you can convert solar power to electric power with 10% efficiency, how large a collector area will you need to meet all your household energy requirements from solar energy? (Will a collector fit in your yard or on your roof?)

I know that it takes two minutes to bring the temperature of a cup of water from room temperature to just about boiling: ready for the teabag. I looked up the characteristics of a microwave oven. Typically their power rating is about 1000 W, but I know that this is the power consumed from the power company, not the power delivered to the water. I looked up the efficiency of microwave ovens, and found that it is about 64%, meaning that a typical oven delivers 640 W to the water.
