Through photovoltaic technology, it is possible to transform
sun rays into electricity. Heat is harnessed effectively with the assistance
from the thermal technology as well. Solar power is trapped in best possible
way with both the technology. Power is generated in local farms in addition to
the farms that are created in large scale.
Different uses of Thermal and
Photovoltaic Solar Technology
Similar to the natural sources like air and water, Sun can be
utilized as a source of energy effectively. Due to immense nature of solar
power, it is considered as the life source for the planet Earth. Solar power is
a renewable form of energy. It can be seen as a clean source of energy that can
made available to the people to manage the consumption of energy. Minimum 50
minutes are required to create the solar power.
Technologies that have helped to
utilize solar power
·
By
using semiconductor cells within a panel, it is possible to create electricity
directly from sun light. The method has been using photovoltaic solar
technology to generate solar energy.
·
In
case of solar thermal technology, separate stages are seen. In the beginning,
the heat is transformed in to mechanical energy. Later on, it can be turned in
to electricity. Due to method of its creation, it also recognized as solar
power of concentrated nature.
Types of installations needed for
solar power
1.
For
homes and relatively substantial community, photovoltaic panels can be utilized
effectively. However, solar thermal technology cannot be used in homes. It
generally heats the environment beyond limits.
2.
For
generating solar power, both the photovoltaic and thermal technology can be
used in large areas as well. The power plant can be created in thousands of
acres. Requirement of energy for large areas are fulfilled in the process.
Through power grids, electricity is generally transferred.
Due to flexibility level of solar power, it can be defined as
one of the preferable choices of renewable energy. Power supply for an entire
city can be managed in the process. It has been found effective for industrial
area as well. Relatively secluded areas
can be lighten up with the solar energy as well.
Photovoltaic Effect
The technology has been discovered by Edmond Becquerel, a French
physicist in 1839. In the beginning, use of solar energy has been seen for
industry. Through electric current, electrons are relocated. Through light,
electrons are excited that is placed within the semiconductor.
Due to heating, photovoltaic cell generates electricity. As a
semi conductor material, silicon is utilized. Direct current runs through the
panel. Later on, it can be changed in to AC current through an inverter.
Solar Thermal Power
ü Low-Temperature
Temperature under 100°C is utilized on the occasion. It can
be utilized for commercial, residential and industrial area. Large amount of
solar power is created with this strategy worldwide. Through thermal conductor,
heat is absorbed. It is transformed in to fluid. Later on, it is directed to
desired area. Uses of various kinds of collectors are utilized for the process.
Both the simple and complex models of devices are noticed.
ü Concentrated Solar Power
Devices that are attached to the ground required for solar
power generation through this technology.
