Solar Panels Solar panel can be defined as the device which take rays from sunlight and absorb them and in return produce electricity or heat. Solar panel consists of solar cells or photovoltaic cells that are used to generate electricity by the effect of photovoltaic. Basically solar panel is a device that change light into electricity. Light from sun is the most powerful source which is used in these devices on low cost. Solar cells are widely spread all over the device and they work together to generate electricity. When more light hits the cell then more electricity is generated. Spacecraft is attached to the solar panels and they are designed in such way that they will always point to the sun and move around according to sun while keeping the rest of the body at rest. Same like the tank turret can show where the tank is going. How do Solar panel works? Solar cells present on solar panels are themselves composed with the layer of silicon and phosphorus which have negative charge on it and also boron which gives positive charge. Electric current is generated when solar panel absorbs photons and in result photon produces energy when they strike with the surface. The fields generated by the solar panel allow electrons to come out from their orbits and the free electrons are pulled into the directional current....
