solar system types
solar system types, Solar panels are not only power generators but also heat things like water from the sun. In this article, we will only look at the types of solar panels that generate electricity and which of them is better for the world
.
Solar panels that generate electricity are
called PV or photovoltaic panels. Solar panels are actually a collection of
solar cells in which several solar cells are combined to form one panel.
The solar cell usually lasts for 25
years after which it does not stop working but the efficiency decreases and it
continues to work. There are basically three types of solar cells.
Types of Solar Panels
Oc Monocrystalline cells
Polycrystalline cells
Th Thin Film or Amorphous cells
Monocrystalline
As the name implies, a cell is made
of silicon crystals. It is usually black. Works even in low light. It absorbs
18% of the light that falls on it and generates electricity from it.
Among the solar cells, it is the most expensive and also the most
sensitive. It has low heat resistance. It usually shows its full performance up
to a temperature of 25 degrees Celsius.
This temperature measurement can vary
according to each solar panel and is written on each solar panel in the form of
NOCT ie Nominal Operating Cell Temperature. If some cells in a monocrystalline
solar panel stay in the light longer and some cells are shaded at the same
time, there is a risk of cell damage. That is, all the cells at a time are
either in light or in all shadows/darkness.
Polycrystalline line
It also has its own name, meaning that a cell is made up of many
silicone crystals. It is usually blue in color and sometimes has waves or spots
of other colors.
It generates electricity by digesting 15% of the light that falls on it
and thus if it is the size of a monocrystalline line it will generate a little
less electricity. Its value is equal to or slightly less than the
monocrystalline line.
It is a little less sensitive and can withstand a little more heat. It
usually works well up to 45 degrees Celsius. This temperature measurement may
be different for each solar panel.
Like the monocrystalline line, if it
is at the same time partially in light and partly in shadow, there is a risk of
cell damage.
Thin-film / e morphology cell
Some people call it solar film. It is
made of unsalted silicon instead of silicon crystal. Usually in black. It
generates electricity by digesting 10% of the light falling on it and thus
generates the least amount of electricity according to its size.
It is the cheapest and has the greatest heat resistance. There is no
harm in living in the dark. Also, it is flexible, so it can be used where the
other two types do not exist.
Here are some key points:
With regard to their types of solar
panels, generating more or less electricity means that if there are three types
of the same size, then some will generate less and some more. Solar panels are
available on a per watt basis, so whichever type it is will give full watts,
just monocrystalline will give one watt in small size and polycrystalline will
give one watt in slightly larger and thin-film will give one watt in a larger
size.
No matter how high the temperature of
any solar panel is, this temperature is written on each solar panel in the form
of NOCT ie Nominal Operating Cell Temperature. With this measure, as the
temperature rises, its efficiency is affected by each degree of increase.
Remember that temperature does not mean the
temperature of the atmosphere, but the current temperature of the solar cell is
observed and also keep in mind that the temperature of the atmosphere is
generally low and lies in the same environment. The temperature of something
happens as if we can stand in the sun, but the iron kept in the sun for a long
time is not being touched.
