<div><strong>By Arshad Khan</strong></div><div> </div><div>Exuding confidence, Union Power Minister Piyush Goyal has said that India would achieve its 100 GW set target of solar energy by 2022. </div><div> </div><div>Goyal said: "If Germany can achieve success in solar power, then why can't India".</div><div> </div><div>In July this year, Prime Minister Narendra Modi extended the prevailing target under the National Solar Mission from 20GW to 100GW. It was decided that out of 100GW, 40GW would be produced from rooftops.</div><div> </div><div>Experts say that India may fail to achieve 40GW from rooftops since the current installation capacity form rooftops is only around 400MW and there is an ongoing dispute between the Centre and discoms of many states over the net metering implementation.</div><div> </div><div>Upendra Tripathy, secretary, Ministry of New and Renewable Energy (MNRE) said that the government is also working towards implementing net-metering policy across the country. "At present out of 21 states where net metering policy was introduces, only four states have implemented the policy. The ministry is working to take the remaining discoms on board. A single window agency to clear legal hurdle for installing rooftops is what the government is looking for," said Tripathy.</div><div> </div><div>To boost productivity, the government is planning to launch solar city programme where in they have selected 60 cities where rooftop installation will be mandatory for residential homes during constructions.</div><div> </div><div>The MNRE is already believed to have received funding interest of 1 billion euros from KfW, a German development bank, $500 million from Asian Development Bank and $500 million from the World Bank. If this goes through, this should be enough to provide debt to around 2.5 GW of rooftop solar.</div>
