Design Your Circuit. Part X11 – Solar Night Lamp


Solar cell is the semiconductor device that converts light energy into electrical energy through the Photovoltaic effect. Solar cells are intended to capture energy from the sunlight while the term Photovoltaic cell is used to denote the devices that receive light from unspecified sources. Solar cells are connected in series to get Additive voltage. The serially connected solar cells are encapsulated as Modules which are then interconnected in series or parallel to get a large Array. Series connection increases the voltage while parallel connection increases the current. Each panel has specified voltage, current and power output which depends on the number of solar cells connected in series and parallel. Let us see some solar facts.
