Solar cells are utilized to transform
solar power in to electricity. Sunlight falls on the solar panel in the roof
every day. Through solar panels, photons are converted in to electrons that are
generally known as direct current. From the solar panel, current goes to the
inverter and several other safety devices. Inverter is responsible for changing
direct current in to alternating current. It is possible to run television,
toaster and computer through this form of electricity easily. These facilities
generally collect power from the wall outlet.
Due to help from the energy meter, it
becomes possible to keep a track on the power generation and consumption. If
the generated power is not utilized in due course then it can go back to the
power grid once again with the assistance from meter. In case of a cloudy day
or night, power is supplied from the grid. Bills are created according to the
net consumption.
Solar Cells
Solar cells can be described as a
semiconductor in square shape. It is generally quite tiny in nature. Uses of
silicon in addition to different conductive materials are seen for
semiconductor. It comes with a lean layer. Due to chemical reactions, electrons
are released with the strike of sunlight in the solar cell. These solar cells
are also recognized as the photovoltaic cells. It can be seen with other kinds
of devices such calculator as well.
Components of solar PV system
PV modules are seen within the
photovoltaic system. It is also remembered as PV panels. In addition, use of
battery, regulator, inverter, mounting hardware and wiring can be noticed.
Through PV modules, photovoltaic cells are arranged effectively. Grouping of
the cells is seen within an array. Some of these arrays help to keep a track on
the sunlight on daily basis. In this way, efficiency of the system can be
increased as well.
Installation, Endurance and Maintenance of the PV system
PV system can be installed within the
house individually. However, it is better to take assistance from the expert to
avoid accident. Moving parts from the photovoltaic system can be noticed due to
its sophisticated nature. Little maintenance can be required for these moving
parts. Connection between the basic modules can be observed. In case of basic
module, moving parts cannot be noticed. Therefore, it can be maintained easily.
Durability level of the components is upheld strictly to avoid issues in future.
Extended life can be ensured from the solar power system in the process.
Requirement of sunlight for PV system
For the generation of solar power,
unobstructed sources of sunlight are required. It is necessary for an entire
day. Energy output can be reduced due to shade on the PV panels. However,
impact of the climate may not be seen majorly on the output. Similar results
can be observed with the snow covers or air temperatures as the solar panels
are placed directly towards the sun. However, it is always better to ensure
abundance of sunlight upon the solar power panel. The amount of power
generation often depends on the size of solar panels as well.
