Solar Power How It Works

Solar power and how it works: On a sunny day, every square meter of the earths surface receives 1000 watts of energy.
If we were to capture that energy we’d all benefit with free electricity from solar power and how it works - pretty tantilizing.
You’ve seen and probably used a calculator that works with no batteries, just light. They run off of solar cells or photovoltaic (PV) cells - or modules (a group of cells that are electrically connected).
Now solar power and how it works, is converting…
the sunlight (photo) into electricity (voltaic) to voltaics.
The semiconductors (such as silicon) that make up the PV, absorb some of the sunlight triggering electrons to loosen and to flow freely. A current is now created with these free flowing electrons. A metal contact is placed on the top and bottom of the PV cell -and by doing such, current can be drawn off and used externally ie: to power a calculator. This current combined with the cells voltage, will define the power/wattage that each of the solar cells can produce.
Pretty cool, er um, hot…As a home owner we’d love to take advantage of solar power and how it works - wouldn’t you?
Peace.
