sine curve उदाहरण वाक्य

A more practical view is this : The peak insolation at the Earth's surface is about 1 kW / m 2 . over the 24 hour cyle it is approximately a half sine curve, integrating and allowing for weather and conversion efficiency ( PV panels about 20 %, other metthods about the same ), you can generally extract an average of about 100 W or so.
