India ranks 4th in the world in terms of energy generation and the government is planning to increase its productivity, with a special emphasis on the green energy sector, said Piyush Goyal, Minister of state for Power, Coal & New and Renewable Energy in Rajya Sabha.

He said that the Ministry of New and Renewable Energy is increasing its renewable energy generation target to 29,800 MW. This will include 15,000 MW from wind, 10,000 MW from solar, 2,100 MW from small hydro and 2,700 MW from bio-power.

The minister told the house that the government is providing a range of fiscal and financial incentives for the promotion of renewable energy under various schemes. For solar power generation, the ministry is implementing a ‘Grid Connected Rooftop and Small Solar Power Plants Programme’ that encourages the installation of solar rooftop systems apart from giving subsidies for the same.

The government has decided to reduce the subsidy on rooftop solar power plants to 15% from 30% due to the decline in price of solar panels, Goyal said and added,” The Department of Financial services has also instructed the Public Sector Banks  to encourage home improvement loan seekers to install rooftop solar PV plants and include cost of system in their home loan proposals.”

The ministry has also released a total of Rs. 957 crore towards Generation Based Incentive (GBI) for wind power producers to promote wind power projects through private sector investment.

Piyush Goyal also shed light on the ministry’s decision to increase renewable energy production and consumption in the agrarian sector. A solar pumping program has been launched for irrigation and drinking water for 1,00,000 pumps during 2014-15. The Minister further stated that for this purpose, Rs 400 Crores have been allocated for current Financial Year.

India’s Floating Solar Panel a Gateway To Clean Energy For Asia

India already makes the solar panels it needs, and is now setting up manufacturing for the floats and anchors needed for floating solar systems.

When the worst floods in a century swept through India’s southern Kerala state in August, they killed more than 480 people and left behind more than $5 billion in damage.But one thing survived unscathed: India’s first floating solar panels, on one of the country’s largest water reservoirs.

As India grapples with wilder weather, surging demand for power and a goal to nearly quintuple the use of solar energy in just four years, “we are very much excited about floating solar,” said Shailesh K. Mishra, director of power systems at the government Solar Energy Corporation of India.

India is planning new large-scale installations of the technology on hydropower reservoirs and other water bodies in Tamil Nadu, Jharkhand and Uttarakhand states, and in the Lakshadweep islands, he told the Thomson Reuters Foundation.

 

Solar panels
Currently floating solar arrays cost about 18 percent more than traditional solar photovoltaic arrays.

“The cost is coming almost to the same level as ground solar, and then it will go (forward) very fast,” he predicted.

 

As countries move to swiftly scale up solar power, to meet growing demand for energy and to try to curb climate change, floating solar panels – installed on reservoirs or along coastal areas – are fast gaining popularity, particularly in Asia, experts say.

The panels – now in place from China to the Maldives to Britain – get around some of the biggest problems facing traditional solar farms, particularly a lack of available land, said Oliver Knight, a senior energy specialist with the World Bank.

“The water body is already there – you don’t need to go out and find it,” he said in a telephone interview.

And siting solar arrays on water – most cover up to 10 percent of a reservoir – can cut evaporation as well, a significant benefit in water-short places, Knight said.

Pakistan’s new government, for instance, is talking about using floating solar panels on water reservoirs near Karachi and Hyderabad, both to provide much-needed power and to curb water losses as climate change brings hotter temperatures and more evaporation, he said.

Solar arrays on hydropower dams also can take advantage of existing power transmission lines, and excess solar can be used to pump water, effectively storing it as hydropower potential.

Big Potential

China currently has the most of the 1.1 gigawatts of floating solar generating capacity now installed, according to the World Bank.

But the technology’s potential is much bigger – about 400 gigawatts, or about as much generating capacity as all the solar photovoltaic panels installed in the world through 2017, the bank said.

“If you covered 1 percent of manmade water bodies, you’re already looking at 400 gigawatts,” Knight said. “That’s very significant.”

Growing use of the technology has raised fears that it could block sun into reservoirs, affecting wildlife and ecosystems, or that electrical systems might not stand up to a watery environment – particularly in salty coastal waters.

But backers say that while environmental concerns need to be better studied, the relatively small amount of surface area covered by the panels – at least at the moment – doesn’t appear to create significant problems.

“People worried what will happen to fish, to water quality,” said India’s Mishra. “Now all that attention has gone.”

What may be more challenging is keeping panels working – and free of colonizing sea creatures – in corrosively salty coastal installations, which account for a relatively small percentage of total projects so far, noted Thomas Reindl of the Solar Energy Research Institute of Singapore.

He said he expects the technology will draw more investment “when durability and reliability has been proven in real world installations.”

Currently floating solar arrays cost about 18 percent more than traditional solar photovoltaic arrays, Knight said – but that cost is often offset by other lower costs.

“In many places one has to pay for land, for resettlement of people or preparing and leveling land and building roads,” he said. With floating solar, “you avoid quite a bit of that.”

Solar panels used on water, which cools them, also can produce about 5 percent more electricity, he said.

Mishra said that while, in his view, India has sufficient land for traditional solar installations, much of it is in remote areas inhospitable to agriculture, including deserts.

Putting solar panels on water, by comparison, cuts transmission costs by moving power generation closer to the people who need the energy, he said.

When that capacity is in place, “then the cost will automatically come down,” he predicted. (VOA)
