Sunny Days Are Here For Solar Power in India

Encourage the distributed solar market: So far, solar in India has seen mostly utility-scale infrastructure projects and current policies point in the direction of more and larger plants. However, solar is also ideally suited as a distributed, consumer technology to power anything from factories to households, irrigation pumps, telecom towers, water purifiers, mobile chargers or lights. This market could grow in a more stable, sustainable way than the infrastructure market, because it would not hit roadblocks such as land availability, grid access and local grid imbalances. Besides the policy support, the government should highlight the importance of a self-sustaining market place.

The Potenial For Solar Energy In India Is Huge

Solar technologies could be characterised as either passive solar or active solar depending on the way they capture, convert, and distribute solar energy. An active solar technique includes using photovoltaic panels and solar thermal collectors to harness the energy. A passive solar technique includes orienting a building to the sun, selecting materials with positive thermal mass or light dispersing properties, and designing buildings that naturally circulate air. Solar power has the potential to reduce India’s dependence on imports of diesel and coal for power generation, reduce greenhouse gas emissions, and contribute to energy security.

India plans grouping of nations with high Solar Power Potential

India is working on a plan to form an association of countries with high solar power potential, aimed at lowering the cost of solar energy and improving the country’s standing at the global climate change and environment protection discussions. The proposal aims to bring together 56 countries with more than 300 days of good solar radiation. The move follows India substantially revising an earlier target of achieving 20,000 megawatts (MW) solar power capacity by 2022 to 100,000MW, requiring an investment of around Rs.6.5 trillion over five years.

Solar Inverter India

Solar energy is simply turning sunshine into electricity. The process begins with solar photovoltaic cells (PV) that capture the sun’s rays and convert them into raw electricity called direct current (DC). DC is then modified into alternating current (AC) through a device called an inverter. AC electricity flows through every outlet of your home, powering everything from lamps to televisions. Solar inverter is the heart of all PV systems. It can also be used in Houses, Guest Houses, Hospitals, Hotels, Shops etc.

About Solar Panels

Solar Panels are a form of active solar power, a term that describes how solar panels make use of the sun's energy: solar panels harvest sunlight and actively convert it to electricity. Solar Cells, or photovoltaic cells, are arranged in a grid-like pattern on the surface of the solar panel. These solar voltaic cells collect sunlight during the daylight hours and covert it into electricity.

Advantages of Solar Panel

Solar panels are clean - while generating electricity from sunlight, solar panels produce virtually no pollution, whereas burning fossil fuels releases large quantities of toxic gases into the atmosphere.

For the consumer, solar panels can free the individual from reliance on the power grid and the monopolistic energy supplier. Once you make the initial investment in hardware, you will have free electricity for years to come.

Fossil Fuels are limited - Although fossil fuel reserves are expected to run dry within the next century, solar power is clean, abundant, and will remain a renewable resource that can meet all of Earth's energy needs for billions of years to come.

How much power do Solar Panel produce?

In direct sunlight at the surface of the equator, a maximally efficient photovoltaic cell about 1/5m in diameter creates a current of approximately 2 amps at 2 volts, however, due to the Earth's atmospheric interference, terran solar panels will never perform as well as solar panels exposed directly to the sun's rays.

Years of overheating and physical wear can, however, reduce the operation efficiency of the photovoltaic unit. Solar cells become less efficient over time, and excess energy is released into its thermally conductive substrate as infrared heat.

The amount of power solar panels produce is influenced by the quality of the solar panel, the materials and technology used in making the solar panel, and the amount of time the solar panel has been in use. When purchasing solar panels, it is therefore wise to look beyond size and look at the dollars/watt ratio.

What are Solar Panels made of?

Crystalline Silicon Solar Panel

The creation of solar panels typically involves cutting crystalline silicon into tiny disks less than a centimeter thick. These thin, wafer-like disks are then carefully polished and treated to repair and gloss any damage from the slicing process. After polishing, dopants (materials added to alter an electrical charge in a semiconductor or photovoltaic solar cell) and metal conductors are spread across each disk. The conductors are aligned in a thin, grid-like matrix on the top of the solar panel, and are spread in a flat, thin sheet on the side facing the earth.

Amorphous silicon solar panels

Amorphous silicon solar panels are a powerful, emerging line of photovoltaics, that differ in output, structure, and manufacture than traditional photovoltaics which use crystalline silicon. Amorphous silicon solar cells, or A-si cells, are developed in a continuous roll-to-roll process by vapor-depositing silicon alloys in multiple layers, with each extremely thin layer specializing in the absorption of different parts of the solar spectrum. The result is record-breaking efficiency and reduced materials cost (A-si solar cells are typically thinner than their crystalline counterparts).

Where does Solar Energy comes from?

Solar energy originates in the depths of our sun. The sun endures a continuous stream of thermonuclear explosions as hydrogen atoms are fused into helium atoms. We encounter the resultant energy as radiation that strikes the surface of the earth. Solar panels convert this solar radiation into useful electrical energy and store them in batteries for our use. Enough solar radiation strikes the earth every day to meet earth's energy needs for an entire year. Solar panels help us harvest this energy and convert it into usable energy to meet the everyday needs of modern life.
