A solar panel is used to harvest power from the sun’s rays and they work by facilitating the movement of light particles to detach electrons from atoms, in the process generating electricity. Solar panels are made up of minute units known as photovoltaic cells. The linkage of many cells forms the components of a solar panel. Photovoltaic in simple terms means the ability to convert sunrays into electricity.
Activation of the Sun
1. Light rays overwhelm and eventually penetrate the cell.
2. Electrons get activated and freeing them up in silicon layers.
3. From the bottom layer, some electrons sling-shot right to the top of the cell.
4. These electrons are energized as they merge with metal contacts as electricity, finding their way through a 60-cell module into a circuit.
5. A closed circuit or loop is created as the electrons escape through a solid contact base underneath into the cell.
Powering From Solar
Solar power is generated when current flows through a wire conduit from an array of modules to terminate in an inverter. As the current flows in, the direct current gets inverted into alternating current with a flow of current and voltage in oscillation. Alternating current is what appliances across the world are operated on. The power flower can be fed into a household circuit or distributed to the region or national power grid.
Solar Installation works in homes or businesses and get powered with solar as a remote unit or an independent power system. Where this exists, it means that the off-grid system will have a set of batteries to store power when it is generated during the day or during sunny hours. At nightfall, the stored power is then called up for use. This is necessary because when night falls, the power modules can only capture minute sun energy since it is at its ebb.
Solar Installation as Back –Up Power
There are also homes that are connected to the grid but have solar installation in their homes. What happens here is that during the day, the photovoltaic cells are exposed to sunrays and in the process, there is conversion of those rays to power. As they are generated, they get fed into the national power grid. This works in factual manner and every unit of electricity generated, stored and distributed can be observed on a dedicated metering system in the household.
This makes it possible for the quantum of power generated to be accounted for and when the homeowner does not use them but releases them into the solar power grid, it is captured and the homeowner can expect payment for every volt of power that has been distributed into the county power grid.
