(NEST) was established in 1998 by Mr. D.T. Barki to address the basic lighting needs of 1.6 billion people who lack access to modern lighting technologies. In 2001 NEST launched the AISHWARYA® 6543 solar mini lamp to replace dirty and unsafe kerosene lamps being used in the rural households globally. NEST’s methodology is to apply its technical and management expertise to develop innovative solar lighting products and implement replicable projects at both micro and macro levels. NEST’s mission is to contribute significantly towards “eliminating light poverty” in the world. NEST is currently involved in high-purity quartz material research that is intended to produce low-cost solar silicon to pave the way for cost-effective lighting solutions to rural communities. AISHWARYA® 6343, a reliable and affordable lighting product for rural household applications, was the first product to be designed and developed at NEST in 2001. It is a solar mini lamp and NEST’s flagship product, which shot to global fame when NEST won the prestigious Ashden Light Award in 2005.

3. Eliminating Light Poverty
There are three kinds of basic poverty that the world has identified, that is, food, clothing, and
shelter poverty. While the world and all its army of philanthropists are largely focused on these
three, Noble Energy Solar Technologies Ltd (NEST), a company with a difference in vision has
identified another kind which is equally relevant yet neglected. This kind of poverty can be called
‘Light poverty’.
Light is the integral part of life. There’s no life without light. In fact, in a recent research, it has been
found that DNA emits photons, the elementary particles of light. While day is signified with
sunlight, the absence of sunlight on the globe is termed as night. But man always needed light
except when he slept. Light is the essence of life. If we ignore its importance, we miss life. Light is
essential for the overall development of man. We cannot even spell ‘enlightenment’ without the
word ‘light’!
While 2 billion people world over have no
access to electricity, and over 100 million
Indian families use smoky and hazardous
kerosene for their lighting purposes, not

was NEST which took up this cause as a
mission and pursued its dream of “Eliminating Light Poverty.”

About the Founder:
Mr. DT Barki, the founder chairman of NEST has been in the solar photovoltaic industry for the last
25 years. A B.Tech graduate in Electronics Engineering (1982) from KREC (now NITK), Surathkal,
India, he has earned international reputation with solar PV technologies, through successful
implementation of several solar projects (cells, modules and systems). He has toured all over the
world to attend national & international conferences, workshops, and business meets on the
industry. He applies his scientific, technical, and management expertise to all aspects of the
challenge to implement sustainable energy services, especially solar PV globally, for the benefit of
people and the planet. He has extensive knowledge in setting up solar cell manufacturing units and
running them successfully. Mr.Barki has several shop floor contributions in inventing many defect
analysis methods in solar cell and module processing. He has won the ELCINA (national) award for
the indigenisation of crystalline PV cells production during his service at BHEL, Bangalore.
After having worked in BHEL, Bangalore for 12 years he came to Hyderabad and served in several
private organisations and was instrumental in setting up both cell and module lines during his
service.
In 1998 Mr. Barki embarked on a journey to provide light to the people living in darkness and
founded NEST that has served many people today. He has clearly laid the foundational values for
NEST to carry forward the mission of “Eliminating Light Poverty” in a much more concerted
manner, this being the hallmark of a true visionary.
His technological and social skills are to bring light to life; because he believes that
Life is Light; Light is Life.

Methodology:
Nicholas D. Kristoff has written an article titled ‘Social Entrepreneurship’ in which he has
addressed an approachable methodology towards Sustainable Development in the world. He cites
many working examples wherein the enterprises with a social cause are proving to be highly
beneficial to the people in the developing countries. Nest has taken to heart this idea, and with its
technological and management expertise has made tremendous progress in making sustainable
development a global reality.
Projects and Activities:
1. NEST has pioneered in the design and development of AISHWARYA®, an affordable solar
mini lamp for the rural households across the world.
2. NEST will always work to develop new solar lighting products and nurture innovative
lighting projects to realize its mission of Eliminating Light Poverty in the world. We are
currently working on the design and development of solar LED lantern in association with
Sankeerna Technologies Inc., USA, who have developed a unique, patented LED filament. It
is AISHWARYA® in a new avatar and is named AISHWARYASUN‐KIRAN360.
3. NEST is working on producing low cost solar grade (SoG) silicon for polysilicon producers
across the world.
4. Solar Lantern Charging Stations: Noble Energy Solar Technologies Ltd (NEST) had
developed AISHWARYA® solar lamps as affordable options for the rural poor to replace
their unsafe kerosene lamps. With the advent of Ashden Light Award 2005, AISHWARYA®
solar lamp became global solar product. While this solar lamp has a section of rural poor
who can afford AISHWARYA® solar lamps, there are many who cannot buy the lamp, though
low‐cost, by making down payment.
