CHANDIGARH: The Punjab Government has initiated an ambitious program to install rooftop photovoltaic solar systems in 120 police stations in the state for power generation.  

Bikram Singh Majithia, Non Conventional Energy Minister, today said that Punjab Energy Development Authority would soon embark on a major programme for these installations in order to increase usage and popularize Solar PV technology for power generation. 

He said that these solar PV systems would be installed in all 120 police stations in the state and each system would generate 2.5 KW power for powering lighting and computer loads in the police stations. He said that the total cost of this project was Rs 6.6 crore.

Reiterating the resolve of Punjab Government to install Solar Power Systems on all government buildings by the end of 2017, Majithia said that the power generated through these rooftop systems would replace conventional energy and also provide backup power during grid shut downs. 

He said that PEDA was already promoting the installation of rooftop PV Power Plants in which capital subsidy was being provided as per the guidelines of Ministry of New and Renewable Energy guidelines, GOI. He said that these projects would also reduce generation cost, which was in the range of Rs. 6-7/Kilowatt hour in the long term and which was also almost comparable to the tariff being charged by the PSPCL from its consumers.

Divulging the details of rooftop solar power systems, Majithia said that PEDA has also carried out a detailed rooftop survey of major Government Buildings in the State and estimated potential was 40 MW. He said that solar power generated from the rooftops would also replace conventional power and provide backup power to buildings during grid outage including surplus power being exported to the PSPCL grid.

CHENNAI, MARCH 1:  

Kiran Energy today announced that it has commissioned a 55 MW DC solar voltaic power project in Rawra village of Jodhpur district of Rajasthan. With this, Kiran Energy’s portfolio of solar projects in the country totals 80 MW.

The company is also building clusters of solar projects in several States, including Maharashtra, Gujarat, Karnataka, Rajasthan and Tamil Nadu. These clusters will have projects of capacities between 50 MW and 100 MW, Kiran Energy said in a press release.

L&T and Mahindra EPC did the ‘engineering, procurement and construction’ work for the 55 MW Rawra plant.

The 55 MW capacity is really three separate projects, with separate power purchase agreements with NTPC Vidyut Vyapar Nigam (NVVN), a power-trading subsidiary of NTPC. These projects were won under the second batch of Phase I of the Jawaharlal Nehru National Solar Mission.

Kiran Energy now operates the largest solar power plant cluster of 60MW with a combined evacuation at a single location in India, the release says.

The plant is expected to produce an average of more than 90,000 megawatt-hours of clean electricity per year, equivalent to the annual electricity needs of more than 2.75 lakh Indian households, reducing carbon emissions to the extent of 80,000 tonnes annually.

Kiran Energy is one of the leading clean energy utilities that has been developing and operating solar power projects across India. In Rajasthan and Gujarat, it now operates an aggregate of over 80MW power plants.

CHANDIGARH: A sum of Rs 16.25 crore has been allocated to UT administration for implementation of Model Solar City Programme. Ministry for new and renewable energy has already chosen Chandigarh as one of the cities to be developed into a solar city. Six rooftop solar photovoltaic power plants have been set up with power generation capacity of 975KW.

Though, The Energy and Resource Institute (TERI) had chalked out the broad outline in 2009, work on ground could not begin as the proposal was pending with the ministry of new and renewable energy for allocation of funds. According to the plan, a 25 Mega Watts solar photo voltaic (PV) plant would also be set up. As of now, UT has no electricity generation of its own. In its pre-feasibility report, TERI has identified 24 of the total 900 small and big parks being maintained by the municipal corporation, which could be looked as potential locations for tapping solar power.

The Tamil Nadu Generation and Distribution Corporation, which has received investment commitments to set up power plants that can generate over 200 MW, has given bidders some more time to submit commitment letters, according to industry sources.

As of Thursday when the utility’s Board met, it had received letters of commitment from bidders to set up “a little over 200 MW” of solar power generation capacity, according to reliable sources.

It is optimistic of receiving some more investment commitments and hopes to tie up for a total of about 250 MW, the source said.

In January, the Tangedco had called for bids from investors to set up decentralised solar power generation facilities across the State. It had hoped to attract proposals for about 1,000 MW of capacity and enter into a 20-year power purchase agreement.

Over 90 bids totalling about 500 MW were submitted with quotes ranging between Rs 5.47 a unit of electricity to up to Rs 18. After assessing the proposals the utility made a counter offer of Rs 6.48 a unit.

Individual investors who planned to avail of accelerated depreciation benefits have largely committed to the offer. Larger, utility scale players looking at standalone projects have not been so enthusiastic, according to industry sources.

Among the large players, Sun Edison, a US-based solar power project developer, which had bid for a total of 50 MW has committed to set up a 10-MW facility, according to sources in the know.

BHOPAL: Country's biggest solar power plant to generate 130 MW electricity would be set up in Neemuch in Madhya Pradesh. The ambitious project cleared by departmental advisory committee of the State department New and Renewable Energy, according to press release here on Tuesday.

1,000 acre land has been earmarked for the plant in Neemuch district. Renewable energy accounts for just five per cent in total energy generation in Madhya Pradesh. At present, work is underway for 311 MW solar power projects in the state.

Lanco Infratech Ltd. (LANCI), India’s second-biggest non-state power generator, is seeking private- equity investors to help expand its solar capacity fivefold as a coal shortage roils its thermal business and payment defaults by state utilities widen the group’s losses.

Lanco needs funds to meet a plan of adding 500 megawatts annually in three years, with 350 megawatts to be built for customers and the rest coming from its own plants, V. Saibaba, chief executive officer of the New Delhi-based company’s Lanco Solar unit said in a telephone interview. Government policies to promote alternative energy sources will make the investment attractive, he said.

“The political intent in India is very strong,” Saibaba said, speaking from his office in Gurgaon near New Delhi. “Constraints like coal availability and fuel import bills will ensure India will have to focus on renewable energy.”

Lanco is joining Tata Power Co. (TPWR), India’s biggest non-state utility, which said Feb. 5 that it is scouting for investors and planning to sell shares at its solar unit as India extends grants to cut solar project costs and ease curbs on equipment imports. A plan announced last year by the Lanco group to raise $750 million selling stake in its conventional power unit to private-equity funds has stalled amid losses that have surged nine times in the first three quarters of the financial year.

Losses Widen

Shares of the New Delhi-based company have slumped 86 percent from a record reached on Dec. 28, 2007 to 11.2 rupees. The slide in the value has eroded the wealth of Chairman L. Madhusudhan Rao, who was a billionaire as late as January last year, according to data compiled by Bloomberg. The shares fell 1.3 percent at 11:39 a.m. in Mumbai.

“Lanco hasn’t done well when it comes to the power business,” which suffers from fuel supply problems, said Gaurav Oza, Mumbai-based analyst at GEPL Capital Pvt. “They seem to have done much worse in managing utilities as compared to their earlier success in construction.”

Lanco reported an annual loss of 1.1 billion rupees ($21 million) for the group in the year ended March 31, its first since its shares started trading in November 2006. The combined loss in the three quarters ended Dec. 31 climbed to 9.9 billion rupees, according to data compiled by Bloomberg.

State-owned regional electricity distributors, often forced to sell energy below costs, are unable to pay producers as the difference between the cost of supply and average tariff has widened. The utilities had debt of 1.9 trillion rupees as of March 2011, government estimates show, even as lenders tightened credit. That has resulted in poor cash flows for Lanco.

Debt Outstanding

The company has 35 billion rupees of receivables, Rohit Sanghvi, an analyst with Prime Broking Co. in Mumbai, wrote in a Feb. 15 report. The outstanding amount is more than Lanco’s market value. Total debt stood at 95.7 billion rupees, of which the solar unit accounted for 5.5 billion rupees.

Lanco may be counting on interest in solar projects as the government targets to build 9,000 megawatts of grid-connected solar plants by 2017, more than eight times its current capacity. Solar-power producers are assured payments through letters of credit and escrow mechanisms set up by state governments, according to Saibaba.

With costs for alternative energy projects coming down, the tariff for solar and thermally produced electricity may reach parity in about three years, Saibaba said.

Interest Costs

Better potential realization is also helping lenders offer cheaper credit for solar producers, said Satnam Singh, chairman of Power Finance Corp. (POWF), India’s biggest state lender to electricity utilities.

“We cut lending rates for renewables this month because we see better returns in the near future,” Singh said in an interview. Of the 23.7 billion rupees sanctioned by Power Finance to renewable companies in the year ending March 31, 15.8 billion rupees was to Lanco Solar, he said.

Solar companies have to pay interest rates as high as 13.5 percent to 14 percent in India, Saibaba said. The weighted average cost of debt for NTPC Ltd. (NTPC), the nation’s biggest power producer, was 8.6 percent according to data compiled by Bloomberg.

India’s policy draft released in December said the government would for the first time fund the solar industry with direct grants covering as much as 40 percent of the upfront cost of building projects. That model has previously been used to build roads, ports, railways and fossil-fuel power plants in India.

Slow to Fund

Private lenders have been slow to fund solar because of a lack of confidence in the technology, according to the draft. Solar companies in India sell power to state utilities which in turn cannot recover their costs from customers who buy power at lower rates.

Lanco will add 90 megawatts of solar capacity by the end of the fiscal year ending March, including a delayed 75-megawatt photovoltaic project for the local state-owned utility in the western Maharashtra state that it won in May 2011, he said.

Another 100 megawatts of capacity being built using solar- thermal technology in northern Rajasthan state has been delayed by a year, Saibaba said. The project, awarded under the first phase of India’s solar auctions in 2010, had to be reengineered to make allowances for differences in radiation levels and delays in getting heat-transfer fluid from U.S. suppliers, he said.

‘Still Grasping’

Lanco Solar is completing a manufacturing plant that will be able to produce 1,800 tons of polysilicon, 100 megawatts of ingots and wafers and 75 megawatts of modules a year, Saibaba said. The company expects to increase that capacity to 250 megawatts of modules annually in three years, he said. The total cost of this plant is 13.4 billion rupees of which 70 percent has been funded by loans, he said.

Private investors may look at the government’s commitment to support alternative energy sources before pledging any funds, said Mahesh Patil, who manages $2.5 billion in equity as co- chief investment officer at Birla Sun Life Asset Management Co. in Mumbai.

“Investors the world over are still in the process of grasping the business dynamics of solar-power developers,” Patil said. “Secondary markets, at least in India, aren’t yet ready to support share sales by renewable-energy companies.”

While alternative energy like solar panels could revolutionize the way we generate power, they haven’t always been as efficient as they are today. This solar power efficiency infographic shows just how far we’ve come in the earliest days of signs of power conversion. To this day labs are coming up with new solar tech & innovations that are using different materials & chemical solutions to convert more of the sun’s rays into viable electricity that can be put on the grid.

1953 Solar Panel Efficiency

In 1953 when most people weren’t concerned with generating alternative green energy solar panels were showing signs of getting to a point where someone could actually power some household lights. Appliances still weren’t faced with energy compliant saving regulations so most appliances wouldn’t have been able to work off of a 1953 solar panel. The efficiency rating of a solar panel in 1953 was cranking out about 4.5% of the available energy from the sun’s rays into electricity. The amount of electricity generated by a solar panel at that time was about 230 watts.

The catch is that in 1953 the size of the solar panel to generate 230 watts was enormous to today’s standards in size of a typical solar panel width and height. The height of a 4.5% energy conversion solar panel producing 230 watts in 1953 was 213 inches tall and 130 inches wide. That is nearly 3 adults at a height of 6 feet tall in height or exactly 17.75 feet tall. The width of this solar panel was about two shorter adults at 10.83 feet. So you could have 3 adults standing head to toe and two shorter 5′ 5″ adults lying down head to toe. That’s a BIG solar panel!

Cost efficiency for a solar panel that was this big in 1953 in generating electricity came out to about $1,785 a watt. Obviously it makes sense why people weren’t to concerned with installing solar panels at their home in this time frame as it was ridiculously more expensive than getting electricity from the power company off of the power grid.

2012 Solar Panel Efficiency

Let’s jump ahead in time about 59 years to current day technology of solar panels. When this solar efficiency infographic was made in 2012 the conversion rate of taking the sun’s energy and turning it into power was at about 15%. That is more than double the rate we were at in 1953. The sad part is there is still about 85% of the sun’s energy just going to waste.

While the efficiency increased quite a bit from 4.5% to 15% the size of a typical solar panel converting this energy into electricity dropped by more than half. Now the size of  a solar panel producing 230 watts in 2012 is only about 64 inches tall and 39 inches wide. Now if you take an adult and put them next to a solar panel they will most likely be taller than the solar panel standing at 5 feet and 3 inches. If you try to take any adult and lay them down to the width of the solar panel they’re going to be longer than the solar panel that is sitting at only 3 feet and 3 inches now.

With all that size reduction and increase in efficiency of energy to electricity conversion in newer solar panels you save a lot of money too. The typical amount you can expect to shell out in cost for a solar panel by the watt of energy production is $1.30 a watt. That’s more than 1,700 times cheaper than a solar panel in the 1953 time frame. Solar looks to be getting quite a bit cheaper huh?

2015 and Beyond Solar Panel Efficiency

The future of solar panels is looking bright with lab produced technology enhancements getting solar panels to about 23.5% efficiency in energy to electricity conversion. The time period is put at around 2015 – to any time in the future we should be expecting to get a solar panel that can generate energy at a 23.5% efficiency rating. That’s going to save even more money in producing solar electricity for sure.

The size of solar panels is expected to continue getting even smaller too with sizes expected to hit 41 inches tall and 25 inches wide. Toddlers will be able to stand next to solar panels in the future and be quite a bit bigger than them it seems. With a height of 3 feet and 5 inches and a width of around 2 feet and 1 inch you could really fit quite a few of these on a roof nowadays. The future looks bright for solar technology as it progresses in better efficient innovations and reduces the size it takes to put them up. This solar power efficiency improvement infographic really makes it easy to see just how far solar technology has progressed in just 60 years.
