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?)
How much energy would you consume daily if you kept a lightbulb of 20 watts on all daylong?

The advantage of the island is the number of different renewable energypotentials. The cost of electricity on the island is $0.39 kWh.1) Using solar radiation photovoltaic technologies, it was estimated that 500 rooftops, with a total surface area of 456 000 m2 will be available to install the photovoltaic panels. Assume that the solar panels actually cover 90% of the available surface area. Given, the size of a standard photovoltaic cell is 156 mm by 156 mm and for a silicon photovoltaic cell, each PV cellproduces a current of 2.5 A at a voltage of 0.5 V. The average daily irradiance for the island is 185 W/m2. Assume the initial capacity expenditure evaluated on a yearly basis of the photovoltaic system, that covers, 90% of the available surface area is US$600 000 and the annual operating cost is US $5…arrow_forwardSolar module will be used to provide the daily energy need of. the room in #12.
