Different Aspects of Solar Panels in India

About Solar Panels
The revolution and development in the world of Solar Panels in the last couple of decades has given significant value to solar energy in the world’s constantly increasing demand for energy. Arrays of photovoltaic cells are used in solar panels so as to convert photos into electricity. These panels provide you clean and renewable energy from sunlight.

Solar Panels literally harvest the suns energy and transform them into electricity that can be used. These panels consist of solar cells arranged in a special grid-like design on their surface. It is these cells gather sunlight and convert the energy into electricity.

Solar Panels
What are Solar Panels Made From?
Solar Panels are made using crystalline silicon and gallium arsenide. While silicon is popularly used in making microprocessors, gallium arsenide is an expensive substance used in make solar cells. In addition, solar panels are also made using alloy of amorphous silicon, where a regular roll-to-roll procedure is used. Solar cells made from this procedure are known as Amorphous Silicon Solar Cells. The solar panels made through this method are highly efficient, durable and also thin compared to those made from crystalline silicon.

Solar Panels for Space Probes
When, it comes to making Solar Panels for space probes that depend upon solar energy, the solar cells are made using gallium arsenide through the process of molecular beam epitaxy. These solar cells have many p-n junction diodes, which are highly efficient in absorbing specific parts to the solar spectrum. Even though the efficiency of this type of solar panels is very high, the materials and processes make it highly expensive for them to be used for household use.

The latest solar panel technology is based upon quantum and molecular level. They are made through the implantation of quantum dots or carbon nanotubes into treated plastic. Contrary to solar panels made from crystalline silicon, these solar panels are not made in clean rooms, thus reducing the costs of production.

Power Produced by Solar Panels
A highly efficient solar cell at the equator and in direct sunlight, having a diameter of 1/5m is going to create around 2 amp current with 2 volt. However, the interference of the atmosphere will always create a difference between the performance of a terrain solar panel and a solar panel at a height. The operational efficiency of a photovoltaic cell can wear out after years of usage and heating. Over a period of time, solar cells turn less efficient, releasing the additional energy into the conductive substrate in the form of infrared heat.

There are many factors that have a direct impact on the power produced by the Solar Panels. These factors are the solar panel quality, the technology and the material used in the manufacture of the panels, and the life of the solar panel. Therefore, when you are buying panels, make sure that you not only consider the size, but also the rupees per watt ratio.

Advantages of Solar Panels
When it comes to what Solar Panels have to offer, there are several advantages to be considered. Solar energy has many advantages over the energy produced by burning oil. In addition to benefiting your pocket, solar energy also means a safer environment.

One advantages of solar panels is that it helps create entirely renewable energy. Even when the sun is not present round the clock or in stormy or cloudy conditions, it is always going to show upon next day and you are going to get a constant supply for energy without any possible end to it.

The next advantage of using solar power is over oil energy. Oil is used by most homes in order to power almost every energy requirement, but it is not a renewable source of energy. Thus, when the supply of oil ends, it is going to end once and for all, meaning everyone will have solar power as the major form of energy source.

Another advantage of using solar power is that solar cells are silent and they don’t emit any sound at all. When they are harnessing the sun’s energy, they would not even make a single twitter. However, the machines used in pumping and burning oil to extract energy create a lot of sound.

There is no pollution emitted from the production of solar energy. This advantage puts solar energy at a big advantage to oil, making solar panels much more rational and practical. However, when it comes to burning oil, harmful gases contributing to greenhouse effect, carbon dioxide and carcinogens are released into the air.

Solar Panels continue to work without requiring any substantial maintenance. This is because there is literally no moving part in a solar cell. Thus there is no wear and tear in a solar panel. Solar Panels can last for a very long time and the only maintenance that you need to give them is an annual cleaning job.

Another advantage of using solar panels is that in the long-term there is lots of money to be saved as compared to using other forms of energy. However, the initial cost of purchase and installation of solar panels can be a little expensive. Once, the solar units are working you don’t have to pay anything to harness the sun’s energy. But, when it comes to energy sourced from oil, the costs are increasing almost everyday. With solar energy as an option, it is to be considered why it is required to pay heavily for expensive form of power when there is free power to be harnessed.

The next advantage of using solar powered panels is that they are simple and fast to install. There is no extensive use of power sources, cords or wire, which means that it is an easy and very fast setup. The next edge solar energy has over other forms of non-renewable energy sources is that the technology is constantly improving, as more and more people are becoming conscious about the benefits on offer. And, this means that there is going to be reduction in the prices of initial setup and installation costs.

Disadvantages of Solar Panels
To everything there is always another side. Therefore, Solar Panels also have several disadvantages, but it doesn’t mean that these disadvantage over shadow their advantages, which weigh all the odds.

One of the disadvantages is that the solar panels and solar cells required to transform sun’s energy into solar energy are quite expensive during initial purchase and installation phase. Another disadvantage of solar power is that it is not available at night time, during cloudy or stormy conditions. This limits the amount of power that gets stored for usage. Sometimes, it may be required to depend upon oil as the source of power.

Cost of Solar Panels in India
At its initial level of introduction in India, Solar Panels are quite expensive. The price of A grade Monocrystalline Silicon solar panels in the country falls somewhere within the range of Rs. 90 to Rs. 130 per watt. Then, there are other manufactures who can supply you the panels at prices ranging between Rs. 72 to Rs. 92 per watt. The warranty offered by most of the manufacturers ranges between 10 to 15 years.

Manufacturers of Solar Panels in India
As of 2010, Solar Semiconductor Pvt. Ltd. was the leading manufacturer of Solar Panels in India. The company, using monocrystalline and polycrystalline technology for panel making sold over 160 MWp of solar panels in 2010. The second leading manufacturer is XL Telecom & Energy Ltd. that uses polycrystalline technology to make solar panels. It had also sold approximately 160 MWp of solar panels in the same year.

The next leading producers of solar panels in the country are Tata BP Solar India and Titan Energy Systems Ltd., both making 100 MWp of panels and both use Monocrystalline and Polycrystalline technology. Moser Baer Photo Voltaic using both the technologies is the fifth leading manufacturer of solar panels in India, having made 65 MWp of panels in 2010.

Installation of Solar Panels
Solar Panels are mainly installed on various types of roofs. They could be mounted as tilted up or as flushed up. If it is possible, it would be ideal to install the panel mounts whenever your home is undergoing are-roofing. When solar mounts are flashed when re-roofing, it is going to eliminate any chances of the developing any leaks in the roof. In addition, it is convenient to point out the rafters when the roof is not installed.

It is important that the mounts should be secured in place using lag bolts made from stainless steel, to be bolted right into the rafters. One of the best things to do is to keep the points of the structural attachment flashed-in. This is going to help avoid the removal and re-installing costs of the panels for decades. The easiest roofs to install Solar Panels are the composition shingle roofs. However, it can be a challenge to install the panels on tile roofs.

Even though the initial cost of purchasing and installing Solar Panels can be an expensive deal, but in the long run, the future of solar power technology is promising and it is going to grow like anything.
