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.

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)

Making a big push for offline sales in India, Chinese smartphone maker Xiaomi, which opened its 1,000th “Mi Store” in the country is on track to reach the target of having 10,000 retail stores by the end of this year, a top company official said on Wednesday.

Xiaomi India said it generated employment for over 2,000 people with the opening of 1,000 Mi Stores, which are spread across 19 states in the country.

“We have been the No. 1 smartphonebrand in India for nine consecutive quarters and our market share in online smartphone business in the country is over 50 per cent.

“The scope of growth in online market share is now limited. Therefore, we are focusing on expanding our offline presence in a big way,” Xiaomi India Managing Director Manu Kumar Jain told a select group of journalists here.

According to him, Xiaomi’s current market share in the offline smartphone business in India is 20 per cent.

“By the end of this year, we are hoping to have 50 per cent of our smartphone sales in the country from offline channels,” he added.

Xiaomi had primarily been an online brand since its inception and started its offline sales in India just two years ago.

The company announced the opening of 500 Mi Stores in the country in November last year, saying that it was planning to open 5,000 such retail stores in the rural parts of the country by end of this year.

“Mi Stores” are similar to the bigger “Mi Home” stores currently operational in the metros and other big cities.

In addition to the 1,000th Mi Store launch, Xiaomi India also announced the launch of Mi Studios, the latest addition to its existing three retail channels.

Located currently in Bengalure and Mumbai, with an average size of 400-600 sq.ft, the new Mi Studios are an optimised version of Mi Homes, Xiaomi said, adding that it was working towards opening 200 Mi Studios by the end of this year.

Xiaomi, which surpassed Samsung to become the market leader in 2018 with 28.9 per cent share in the Indian smartphone market, also has over 5,000 Mi Preferred Partner (third-party) stores spread across over 50 cities.

“We are learning from other other brands such as Samsung and Vivo in expanding our offline presence in the country,” Jain added.
