A community plans to build a facility to convert solar radiation to electrical power. The community requires 2.60 MW of power, and the system to be installed has an efficiency of 30.0% (that is, 30.0% of the solar energy incident on the surface is converted to useful energy that can power the community). Assuming sunlight has a constant intensity of 1 200 W/m2, what must be the effective area of a perfectly absorbing surface used in such an installation?
What area is needed for a solar collector to absorb 45.0 kW of power from the
Sun's radiation if the collector is 75.0% efficient? (At the surface of Earth,
sunlight has an average intensity of 1.00 × 10³ W/m².)
An earth-orbiting satellite has solar energy–collecting panels with a total area of 4.0 m2 . If the sun’s radiation is perpendicular to the panels and is completely absorbed, find the average solar power absorbed and the average radiation-pressure force.
