Overview Conversion from DC to ACStandard test conditionsUnits Power output in real conditions

Solar power needs to be converted from direct current (DC, as it is generated from the panel) to alternate current (AC) to be injected into the power grid. Since solar panels generate peak power only for few hours each day, and DC to AC converters are expensive, the converters are usually sized to be smaller than the peak DC power of the panels. This means that for some hours each day the peaks are "clipped" and the extra energy is lost. This has very little impact on the total e

Standard Test Conditions (STC) of a Photovoltaic Panel

Photovoltaic PV panels convert the solar energy from the sun into electrical energy. But to do this they require a sufficient amount of solar irradiance to hit the surface of the panel. In solar terms, irradiance represents the intensity of sunlight falling on the solar panel.
