India has lost another case against the US at WTO as the body ruled that India's domestic content requirements under its solar power programme were inconsistent with the international norms.
India will now approach the appellate body of the Geneva-based WTO against the dispute panel's ruling, an official said.
Last year, the US dragged India to WTO on country's solar mission plan.
The US alleged that India's programme appears to discriminate against the US solar equipment by requiring solar energy producers to use locally manufactured cells and by offering subsidies to those developers who use domestic equipment.
It also alleged that forced localization requirements restricted US exports to Indian markets.
On January 11, 2010, India launched its national solar policy Jawaharlal Nehru National Solar Mission.
The country has an ambitious target of generating 20,000MW of solar power by 2022.
