How do Solar Panels Work?

Solar panels comprise mainly of silicon solar cells. Some of these silicon cells have boron in them while others have phosphorus. Cells with boron produce negatively charged silicon atoms while those having phosphorus produce positively charged atoms. When the solar panels are exposed to sunlight, the presence of opposite charges triggers reactions that convert the sun’s energy into DC current.  That is why solar panels are almost always installed on high rooftops so that they can harness optimum power through maximum exposure.

The solar cells in individual solar panels are connected to each other through thin strips of materials that are good conductors of electricity. This way, a seamless electrical circuit is created in each individual solar panel. Different panels are then linked with each other through twin leads located at the rear surface of each panel. A large and continuous solar panel is thus created which is then connected to the inverter.

The Electricity Meter

Solar power systems also have an electricity meter to measure the amount of electricity consumed by you and the amount that is passed on to the grid. Such measurements are usually updated every thirty minutes. At the end of the month or a predetermined cycle, your electricity provider calculates the amounts and prepares your bill. You can get credit on your bill amount if your panels produce and supply more electricity to the grid than what you consume. Some providers also purchase surplus electricity directly from you for the grid.

The time lapse cameras available nowadays are all powered by solar energy.
