Solar Manufacturing in India

Introduction

India has made significant progress in the solar capacity installation. Also India inspires the world in Solar energy generation and leads through International Solar Alliance.

However, India is not a solar panel manufacturer.

India, aiming to be a global player necessitates to manufacture solar panels in India

Why

To achieve national goal of installing 100 GW by 2022 [60GW from large plants and 40 GW from roof-tops]

This domestic demand necessitates of demand of solar panels

Overdependence on imports

Nearly 92% per cent requirement of its solar equipment through imports and China is the leading supplie r

Employment generation
Aiming to be net exporter and explore untapped markets
Thriving and happening industry

It is consistent with UN Sustainable Development Goals and future seems to be renewables

Despite of measures taken by Govt, there is a long way to go

Steps taken by Govt

Solar manufacturing promotion is included in the National Solar Mission
India’s Manufac uring Policy recognizes solar manufacturing as an industry with ‘< pan style='font-weight:bold;font-family:"Nirmala UI";font-size:11.0pt'>strategic importance'
100% FDI through automatic route is allowed for solar manufacturing in India
25% capital subsidy for solar manufacturing units under M-SIPS
Viability gap funding (VGF) scheme for Govt companies to setup solar power plants under costlier, made in India modules

Terms

HELIOSTAT

It is an apparatus containing a mo vable or driven mirror, used to reflect sunlight in a fixed direction.
As the sun moves across the sky, a heliostat makes small adjustments to the position of a mirror in order to keep reflected light on a target.

Luminescent Solar Concentrators

Thin sheet of material covered over large area , directs sunlight to the cells mounted on thin edges of material
Thin sheet contains polymer material like polymethylmethacrylate PMMA and doped with luminescent species such as organic dyes, quantum dots or rare earth complexes
Cheaper alternative. Increases production of power

Photo Voltaic Electricity

When enough photons are absorbed the negative layer of photovoltaic cell, it frees the electrons which migrate to positive layer creating a voltage differential

Solar Thermal Electricity

Mirrors placed which deflect sun energy onto a glass tube containing fluid(generally synthetic oil, molten salt, pressurized steam) which gets heated up and hot steam generated that drives turbines
Solar thermal - anything that is heated directly by sun Ex: Solar Cookers, Solar Water Heaters

Photo-Voltaic (PV) Integrated Micro Solar Dome (MSD)

Surya Jyoti
In order to capture day light and concentrate the same inside a dark room, particularly in urban slum or rural areas which lack electricity supply, a low cost and energy efficient Micro Solar Dome has been tested and developed.
Micro Solar Dome (MSD) is a clear and green energy initiative of the Department of Scienc e and Technology [NOT TERI]

The Micro Solar Dome (MSD) is a day and night lighting single device unique in its features

How it works

It has a transparent semi-spherical upper dome made of acrylic material which captures the sunlight and the light passes through a sun-tube having a thin layer of highly reflective coating on the inner wall of the passage.
It also contains a lower dome made of acrylic. There is a shutter in the bottom of the lower dome which can be closed, if light is not required in the daytime.

It is leak proof and works throughout the day and 4 hours continuously after sunset

Solar Park

It’s a concentrated one of development of solar power generation projects and provides developers an area that is well constructed, with proper infrastructure, access to amenities and by minimizing paper works for project implementation

Solar Cells

When sunlight strikes the PV module, made of a semiconductor material, electrons are stripped from their atomic bonds. This flow of electrons produces an electric current.

First Generation solar cells are made from silicon, are usually flat-plate.

Second-generation solar cells are called thin-film solar cells because they are made from amorphous silicon or non-silicon materials such as cadmium telluride.

Third-generation solar cells: They are made from a variety of new materials besides silicon, including solar inks using conventional printing press technologies, solar dyes, and conductive plastics.

Perovskite Solar Cells

A perovskite is a material that has the same crystal structure as the mineral calcium titanium oxide (also known as Perovskite).
Perovskite Solar Cell is one that includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light harvesting active layer.
Perovskite captures energy from a different part of sunlightâ wavelength than silicon.
Perovskite solar cells in last few years have outpaced all other third-generation solar technologies in terms of efficiency and cost.
