- 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?)For a total PV module of 25m2, what would be the PV power for each if conversion efficiency is 15% on days when an angle of a south-facing collector in [city] be tipped up to have it normal to the Sun's rays at solar noon?At a certain location, the solar power per unit area reaching Earth's surface is 200 W/ m^2, 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?

- The average electricity consumption of a house in Gainesville is known to be 1,036 kWh in a month (One month = 30 days). They would like to install solar panels of 30 % efficiency to generate this electricity. Given that the average solar power density in Gainesville is 5.47 kWh/m2/day, how much surface area must the panels occupy? Calculate the result in m² but do not write the unit. Round off you E swer to a whole number (zero decimal place.)In a home, 8 lamps, 3 fans and 2 Air conditioners are used. The ratings of each lamp is 40 Watts. The ratings of each fan is 75 Watts. The ratings of each Air conditioners is 1300 Watts. Calculate the total electrical energy consumed by these loads for last month (February 2021).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)?

Solar radiation reaching the ground is approximately 150 W/m2.

Calculate the value of Solar constant ?At a certain location , the solar power per unit area reaching Earth’s surface is 200 W/m square , average over a 24 hours day. If the average power requirement in your home 4.0 KW you can covert solar power to electric power with 13% efficiency. How large a collector area will you need to meet all your household energy requirements from solar energy?A hot water heater in a residential home runs for an average of 2.5 hours per day with a heat energy input of 4 kW. What would be the annual cost for hot water in this home using a gas hot water heater if the cost of natural gas is $0.38/m3? The gas water heater can get 26 MJ of energy from 1 m3 of natural gas.
