About 40 kilometres from Delhi, in the bustling real estate market of Noida-Greater Noida, lies the biggest irony that the renewable energy industry faces. Indosolar, the country’s largest manufacturer of solar photovoltaic cells, has set up a 400 megawatt unit. Its entrance is slick and ultra-modern, typifying the product it manufactures. Stepping into the 28,000 square metre production unit, one is struck by the shimmering clean, futuristic and sleek production line, symbolic of the clean future that solar power promises.
Polysilicon wafers, the raw material, can be fed at the starting point. Solar cells, efficiently packed in boxes, can be collected at the end point. But none of this is happening. The production line stands still. One production line of Indosolar stopped making cells in January last year. The other was shut down a few months later in September. In fact, at present, 80 per cent of the country’s manufacturing capacity is shut.
Herein lies the irony. Why is India’s largest solar cell maker not producing at a time when the country is in the midst of implementing its most ambitious and arguably the world’s quickest solar energy mission?
The answer is simple, yet perplexing. “We have no orders,” says Rahul Gupta, who set up Indosolar in 2009. “We took the pains to get the most modern manufacturing units designed in Austria. Our in-house research and development increased the efficiency of our cells remarkably. As Rajasthan and Gujarat have gone into an overdrive and are installing hundreds of megawatts of solar energy, it should have been heydays for Indian manufacturers. Instead, there is bankruptcy, loan restructuring and pleas to the government for support against international competition,” he rues.
The sunshine industry, literally and figuratively, has been allowed to fade away. There are loopholes in the existing policies. While foreign manufacturers dump their products at dirt cheap prices in the country, domestic manufacturers are finding it hard to compete.

Sunshine sector loses sheen
Going solar is no longer a bright idea for the four-decade-old photovoltaic manufacturing industry. This high-potential renewable energy sector has suffered a serious setback in India as much as across the globe. And the alarm bells are ringing loud.
In the 1970s, public sector companies Bharat Heavy Electrical Limited and the Central Electronics Limited were the first to make solar equipment in India. But these were primarily for research and development. In the 1990s, some more companies started small-scale manufacture of solar equipment. These were restricted to manufacturing for household applications. It was in 2006-07 that Moser Baer, an optical storage media manufacturer, set up the first commercial-scale manufacturing plant of 40 megawatt (MW) capacity. This was to make solar cells, an electrical device that converts light energy into electricity (see ‘Photovoltaic technology’,).
The industry got the much-needed push from the ambitious Jawaharlal Nehru National Solar Mission (JNNSM), which aims to achieve 22,000 MW solar energy generation by 2022. The growing global demand led to mushrooming of domestic players. The cell manufacturing industry, that was mostly export-oriented and catered to the European market, started aggressive manufacturing anticipating a huge domestic demand coupled with the biggest ever increase in global demand for solar photovoltaic. India now has an installed manufacturing capacity of 2,000 MW for solar modules and 900 MW for solar cells (see ‘Manufacturing capacity in India’,). Nineteen cell makers are registered with the Ministry of New and Renewable Energy (MNRE). The country has more than 50 module makers.
But despite the good start, the entire solar manufacturing sector is in a state of collapse. More than 80 per cent of the units in India are closed. What went wrong?
The solar manufacturing sector, say analysts, followed the most optimistic projections for future orders and created a huge overcapacity build-up. Post-2004, after the feed-in-tariffs were announced in Germany, the industry went into an overdrive. Feed-in-tariff is the high rate that the government gives developers to promote clean but expensive energy.
In the global solar photovoltaic demand, the biggest jump happened in 2010. From a little over 7,000 MW in 2009, the demand shot up to close to 20,000 MW in 2010. This is when the cell manufacturing capacity increased extensively. According to estimates by Bloomberg New Energy Finance, world’s leading provider of industry information, the current global demand is about 30,000 MW. But the manufacturing capacity is double that.
European countries, which drove the initial investments and supported the sector with attractive policies, were the ones responsible for the industry’s downfall. The countries initially gave significantly high feed-in-tariffs for generating power from solar technology.
Germany has been the leader in solar installations ever since it started giving high feed-in-tariff in 2004. By 2010, Germany accounted for 43 per cent of cumulative installed solar photovoltaic capacity, followed by Spain (10 per cent), Japan (9 per cent) and Italy (9 per cent). Till 2008, Germany had accounted for almost 50 per cent of the global demand for solar photovoltaic. Spain, which started giving feed-in-tariffs in 2006, has also been a big market. So has been Italy.
With overproduction and bulging solar power purchase bills, European governments started backtracking on their supportive policies for their manufacturers. Spain was the worst hit. Its government announced complete moratorium on support to solar projects. “Initially, when Spain had announced high feed-in-tariff for solar power, it had budgeted for 600 MW capacity. However, plants for 2,600 MW were set up. The country simply did not have the cash to support such a mega scheme,” says a manufacturer who did not want to be named.
No wonder, the prices of solar equipment plunged between 2008 and 2011. Photovoltaic modules cost 60 per cent less, estimates Bloomberg. Other estimates point to a greater decline. The price of polysilicon, the basic building block for polycrystalline solar cells and modules, has fallen from US $500 per kg in 2008 to US $25 per kg now.
This sharp fall in prices made governments wary of paying high feed-in-tariffs. “Moves by Spain and the Czech Republic to make retroactive cuts in feed-in- tariffs for the already operating photovoltaic projects damaged investors’ confidence,” states the report Global Trends in Renewable Energy Investment 2011 prepared by Bloomberg and the United Nations Environment Programme. “Other governments, like those of Germany and Italy, announced reduction in tariff for new projects—the logical step after a fall in technology cost. What caused concern was the fear that governments facing economic hardship may go back on the previously promised deals for the existing projects, damaging returns for equity investors and banks,” it adds.
No demand in India
The JNNSM provided the policy backing for domestic content for projects under the mission. In the first batch of the mission’s first phase, solar photovoltaic modules based on crystalline technology had to be sourced locally. In the second batch, both crystalline cells and modules manufactured in India had to be used.
The domestic demand did not cover the more contemporary and low-cost thin-film solar modules. MNRE allowed free import of thin-film modules on the ground that India had only one thin-film module producer—Moser Baer. The competition in JNNSM has, therefore, been between imported thin-film technology and domestically assembled crystalline silicon modules. But the competition has been far from fair.
Technology choice for projects under JNNSM has been heavily skewed in favour of thin-film modules which were cheaper. But the cost-benefit is neutralised because thin-film modules are less efficient. More thin-film modules are required to generate the same amount of electricity. This increases the demand for land. Almost 60 per cent of the projects under JNNSM’s first phase have opted for imported thin-film modules. Only 14 per cent of the modules produced globally are thin- film.
Also, in state programmes like the Gujarat solar policy, that aimed to achieve 500 MW by 2014 but has already achieved its objective, it is not mandatory for project developers to buy equipment made in India. The developers prefer to import equipment from China and the US as they are cheap. Charanka Solar Park in Gujarat, Asia’s biggest with 214 MW operational capacity, has equipment mostly from the US and Chinese manufacturers like MEMC, Suntech Power and CSun. Moser Baer plants in Kamalpur and Zenabad in Gujarat have equipment from LDK, Trina and other Chinese companies, not from the company’s Indian manufacturing plant. Reliance Power’s 40 MW photovoltaic project in Rajasthan uses modules from First Solar, a US company. “Given the present state, how can domestic content requirement hold? Developers take solace in importing,” says Krishnappa Subramanya, former CEO of Tata BP Solar and now an independent consultant.
Only those Indian project developers who also make solar equipment buy equipment from their own plants. Tata Power’s 25-MW plant in Gujarat installs in-house Tata BP modules. Lanco Solar’s 35-MW plant in Rajasthan also installs self-manufactured modules.
Despite efficient solar manufacturing, “only about 20 per cent of the manufacturing capacity in the country is operational,” says Rahul Gupta, managing director of Indosolar. The rest is dormant as there is not enough demand for Indian cells and modules, he adds. His own state-of-the-art plant in Greater Noida, which has two manufacturing lines of 90 MW capacity each, and another line of 200 MW that was still being set up, closed in September 2011.
The company retrenched 170 staff, mostly engineers. Indosolar had made a combined investment of Rs 1,200-1,300 crore. The company’s last year’s balance sheet shows it lost about Rs 200 crore due to forced closure. “In 2010, what we produced in the morning was off to airport by the afternoon. Today, we don’t have clients,” says Gupta. The company lost clients in France, Lithuania, Italy, Hungary, Spain and Greece.
This is no isolated case. Maharishi Solar and Tata BP have similar stories to tell. Of the three Tata BP production lines, only one is working. The company had to remove more than 200 workers because of lack of demand. “India has lost the manufacturing plot. Very little of manufacturing capacity established in the country is operational,” says Subramanya. Eighty per cent of the Indian manufacturers are now negotiating loan repayment plans with banks because they do not have the money to clear the dues. Debt restructuring is often seen as a precursor to bankruptcy.
Industry is on the verge of collapse. The solar power sector has turned into a purely import business.
Materials like silicon absorb the energy emitted by the sun and turn it into electrical current. This is known as the photovoltaic effect, that causes them to absorb photons of light and release electrons
Stage2: Solar Cells
A solar cell is a thin semi-conductor wafer, specially treated to form an electric field. Electrical conductors are attached to either side of it to form a circuit which captures the released electrons in the form of electric current
Stage3: Solar Panel
A solar panel or module is a collection of cells that are electrically connected to one another. These modules are designed to supply electricity at a certain voltage, such as a common 12 volt system
Stage4: Solar Power
Photovoltaic panels produce direct current (DC) electricity. An inverter is, therefore, required to convert DC to AC (alternating current), because we need AC to power our everyday gadgets and lights
