Solar tracking system
Hi this is vivekanand goud recently I developed a solar tracking system project.this article tells about the solar tracking system
Global warming has increased the demand and request for green energy produced by renewable sources such as solar power. Consequently solar tracking is increasingly being applied as a sustainable power generating solution.
The use of tracking technology allowing solar module to follow the sun. So optimize the incident angle of sunlight on their surface .this can increase electricity production by around a third and some claim by as much as 40% in some regions, compared with modules at fixed angle solar system.
The solar system is a device for orienting a solar panel or concentrating a solar reflector or lens towards the sun. Concentrators, especially in solar cell applications, require a high degree of accuracy to ensure that the concentrated sunlight is directed precisely to the powered device. Precise tracking of the sun is achieved through system with single or dual axis tracking system.
Single axis tracking system
Solar panels with single axis tracking system. The panels can turn around the centre axis.
Dual axis tracking system
Dual axis tracking is typically used to orient a mirror and redirect sunlight along a fixed axis towards a stationary receiver. But the system can also gain additional yield on your PV cells
There are three main solar power technologies.
1. Photovoltaic –PV
2. Concentrated photovoltaic –CPV
3. Concentrated solar power –CSP
Photovoltaic –PV
Photovoltaic power generation done by employing panels composed of a number of cells containing photovoltaic material (often silicon). This photovoltaic material then converts the solar radiation to electrical current.
Concentrated photovoltaic –CPV
Concentrated photovoltaic power generation uses the same photovoltaic material as PV. On CPV panels the solar radiation is however concentrated onto the material using lenses.
This creates a much higher electricity output from photovoltaic material for the installation to work it is essential that the CPV panels follow the sun during the day.
Concentrated solar power –CSP
Concentrated solar power is based on concentrating sunlight onto a small surface which is then heated. The heat is converted to energy through either a sterling engine or a fluid that is heated and used for power generation. Precise movement is essential for this installation to work effectively
CSP can be obtained through different solar power systems such as a solar power with heliostats, a parabolic through and a Fresnel collector.
