Here you will find out how sunlight produces electrical energy, “electricity”, and how a solar array is constructed. In technical terms, the solar system is also called the photovoltaic system. “Photo” comes from the Greek and means light. In addition, the word “Volt” is in it. Volt is the unit of measurement for electrical voltage. Wonder more? Details awaits you below.
Solar array review article
A solar array consists of many individual solar cells, which are about as big as a palm. A single solar cell produces only a small amount of electricity. To operate an MP3 player, you would need 7 such solar cells. Mostly 60 solar cells are combined in one plate. Such a plate is called solar module. A photovoltaic system on a house roof consists of 10 to 100 such solar modules.
How does a solar cell work?- Solar array
When converting the sun’s rays into electricity, we take advantage of a special feature of sunlight:
The sunlight consists of innumerable tiny sources of energy (photons). When these hit certain substances (such as silicon), they release the negatively charged electrons. These then move up to the tracks. The positively charged “holes” travel simultaneously to the rear side contact.
Since negative and positive charges attract each other, but the boundary layer prevents a direct connection, the electrons must take the “detour” over the connected line. On the way they bring, for example a lamp to light up.
In a simple way, this solar array system creates electricity easily.
How does a solar system work?- Solar array information and tips
The energy of the sunrays generates direct current in the solar cells. This flows to the inverter. This device has the task of converting the direct current into alternating current so that it fits into the public grid. Now the alternating current still flows through a counter so that we know how much electricity is generated. Now we can use the electricity on the spot.
If more electricity is produced than is consumed on sunny days, the surplus flows into the public grid ( energy recovery in the grid).
Conversely, in bad weather or in the evening often more power is consumed than the solar system produces. Then the missing electricity flows from the grid into the house (energy supply from the grid).
