The best solar panels currently available are about 19% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity per day (1 kWh=1 kilowatt hour; 1kW=1000J/s). Assuming 8.1 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical home’s electricity. The energy rate supplied by the sun is 1.0kJ/s times meters squared  .

What area is needed for a solar collector to absorb 45.0 kW ofpower from the Sun’s radiation if the collector is 75.0% efficient?(At the surface of Earth, sunlight has an average intensity of1.00 * 103W>m2.)

Assume our atmosphere absorbs 23% of the incoming solar radiation, and that the distance from the Earth to the Sun is 1.5 × 1011 m. From this information, what do you expect is the total power output of the sun? [IMPORTANT: to express a number like 2 × 1021, type 2e21] Please enter a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 1e6, 5.23e-8 Enter answer here W Part b How much solar energy do you absorb after sunbathing for an hour? Assume your skin has an exposed surface area of approximately 1.2m², and you absorb 50% of the incident energy. Give your answer in megajoules.
