Advanced Solar Materials Enable the Electrification of Remote Corners of Ladakh

Ladakh_630x315

Issue:

Ladakh is one of the most isolated areas in India. It is at a high altitude and has an extremely cold climate. Many villages in Ladakh do not have access to grid electricity due to their remoteness, and it is very costly to take grid lines to these areas. Decentralized power is the solution for these areas, but it is difficult and costly to transport diesel because it can be ecologically harmful, while other clean energy sources are either not available or difficult to harness.

Challenge:

To establish a sustainable energy source in the remote and highly adverse terrain of Ladakh. This power source was required to not only perform in the harsh climate, but also to reliably last for many years and work at a high efficiency to supply maximum power at a competitive price.

Solution:

DuPont collaborates closely with Moser Baer, and supplies materials for photovoltaic (solar) cells and panels. Moser Baer worked with DuPont to install solar farms in remote locations of Ladakh. They manufactured and installed 500 kilowatts of solar panels using DuPont materials in several villages in Ladakh. These panels are now powering up 350 houses with sustainable energy supplied at a lower cost than running diesel based generators.

The reliability offered by DuPont™ Tedlar® polyvinyl fluoride film-based backsheets has enabled the system to perform with minimum degradation by protecting the panels from UV rays, helping to ensure the expected 25 year system lifetime by withstanding the severe climate.

The DuPont™ Solamet® photovoltaic metallization paste used by Moser Baer increases the power output of solar cells, reducing the number of panels required to produce the same amount of power.

The panels installed are designed to provide decades of clean energy to these houses. This solution is easily scalable, and can be used to provide a reliable off-grid energy solution all across India.

Benefit

The collaboration between DuPont and Moser Baer resulted in many benefits for all the stakeholders involved:

•   Electricity availability in hitherto unconnected areas

•   Extended system lifetime

•   Lower degradation, resulting in maximum power 
produced over the system lifetime

•   Cost efficient solution

•   Lower dependence on fossil fuels

•   Highly modular and scalable solution
