Use the formula Efficiency = (Output Power / Input Power) × 100% to find out how well your solar panel changes sunlight into electricity. Solar panels can make energy even when it is cloudy or cold, so do not think they only work when it is sunny. . You will learn how to calculate PV efficiency calculation with easy steps and examples. When sunlight strikes the semiconductor material within the panels, it excites electrons, generating direct current (DC) electricity.
