Putin says Russia has successfully carried out test of nuclear-powered cruise missile
A Russian air strike has killed at least three people in the Ukrainian capital. The attack hit two high-rise buildings in Kyiv in the early hours of Sunday. Kyiv has accused Moscow of trying to cause a “humanitarian catastrophe” as the cold weather sets in. Russia says it's responding to Ukrainian drone attacks on its capital. Meanwhile ...

Calculate Solar Panel Efficiency with Simplest Method To calculate the solar panel efficiency, you need to divide the Wattage per unit area (Pmax/total area in sq.m.) of the solar module by the STC Irradiance value (1000W/sq.m.). This is the simplest way to get any solar PV module’s efficiency. Solar Panel Efficiency Formula: Efficiency (%) = (Pmax ÷ Area) ÷ (1000) x 100% where, Pmax = solar panel peak power (in Watts) Area = length x width of the solar panel (in sq.m.) 1000 = Standard Test Cond
