SU-KAM UNVEILS INNOVATIVE SOLAR POWERED SOLUTIONS

Su-Kam Power Systems Limited, the leading player in the power back-up industry in India, unveiled Su-Kam Brainy – a complete solar package for home usage and Solar Power Conditioning Unit.

One of the main attractions was “Brainy” – a complete solar package for home usage that operates on both Solar as well as Grid Power. It enables a common user to install the complete solar system at his home and utilize the solar energy generated from the panel to charge the battery and reduce his consumption from grid power. Su-Kam is providing the complete package to the end user which consist of 850 VA UPS with in-built solar charge controller, solar panel and a trolley

Solar Power Conditioning Unit is an integrated Solar System which runs both on Solar and Grid power and is mainly for medium to large consumption. It consists of solar charge controller and inverter that enable users to charge the battery bank for the inverter either through grid power or solar power. Solar Charge Controllers are required for monitoring and controlling the charging of battery bank connected to the PV modules.

Apart from this, the other main attractions were the complete range of solar products for diverse requirements of customer’s need right from the small solar powered Home lighting solutions, MPPT based Solar Charge controller, High Capacity & High frequency Solar Inverters, Grid Interactive Solar Inverter, Solar Series Batteries, a remote monitoring software to control, monitor and operate solar power solutions in remote areas.

Apart from Solar Products, Su-Kam plans to focus more on big Solar Projects both in rooftop and centralized street lighting solutions, similar to what we have done at Assam Rifles, Tamil Nadu Energy Development Agency, Assam State Electricity board, to name a few.

The solar industry has a growing share in the global energy market. According to a report, grid-connected solar systems should increase to about 42 GW in 2012, reflecting a double digit compounded annual growth rate.

The Indian Solar Energy sector has been growing rapidly, in the past few years, majorly due to Governments initiatives such as tax exemptions and subsidies. Due to technical potential of 5,000 trillion kWh per year to minimize the operating cost, Solar Power is considered to be the best suited energy source for India. Today the Solar power has an installed capacity of 1000 MW which is about less than 0.1% usage, currently total installed renewable energy stands at 13,242.41 MW as per MNRE.

Speaking on Su-Kam’s commitment to the Solar sector Mr. Kunwer Sachdev, Managing Director, Su-Kam said, “With theSolar products market in India constantly evolving, the user requirements and needs are also constantly changing. Hence it is very important to understand the market acceptance of the product before launching them. Going forward, Solar would also be a key focus area for Su-Kam with a large number of investments already ear-marked for development and manufacturing facility of Solar products. Su-Kam already has an exhaustive range of solar products available in the market covering wide range of sectors such as: Residential Bungalows, Industries, Hospitals, Banks, Commercial Establishments, Telecom, Rural Areas, Corporate offices, State and Central Govt. offices and institutions. We plan to invest Rs. 200 Cr in the sector over the next 3 years.”

“Alternatives like Solar and Wind energy and hybrid systems can address the challenge of power unavailability in semi-urban, rural and remote areas. Renewable energy will not only cut down the operational expenditure by 15-20% but also address problems that arise due to power crisis. The subsidy provided by the government for Solar Power Providers will offer major benefits to key market players,” added Mr. Sachdev.

Turning waste into power

Just when Bangalore is staring at a sea of garbage piling on its streets, one Bangalorean has shown how waste can be effectively converted into fuel. And he has done it in Malaysia, which has successfully adapted his technology.

KS Sivaprasad holds the patent for developing the Refuse Derived Fuel (RDF) Power System — a technology that converts mixed garbage to fuel to finally produce power. Today, he is director (technical advisor) of Core Competencies, a Malaysian firm which provides electricity to 2 lakh people there. The plant daily converts 700 tonnes of garbage to 8.9MW of power.

Sivaprasad, a resident of Madiwala, has just one regret — despite the huge success rate in other parts of the globe, no one in India and Bangalore in particular has approached him to utilize this technology
“This is green power. We obtain this after removing all the pollutants, including heavy metals, from the mixed garbage. All we require is a plot of land to station this plant,” Sivaprasad said.
THE GENESIS

It all started in the 1970s when US was looking to generate alternative fuel from municipal waste in the wake of the oil crisis. “That’s when the idea struck me and I developed this technology in India,” said Sivaprasad, who set up a plant in Madiwala then. The biggest global recognition for RDF came in 1995 when he participated in a UN conference in Bangkok.
He made a presentation and got a call from the Malaysian company which wanted to introduce this technology there. In 2006, they started work on building the plant and by 2009, the plant started power generation. He is working on a second plant which will treat up to 1,000 tonnes of garbage.
How power is generated

Segregation is done in several steps at the plant Non-combustible matter is segregated and moisture content reduced by drying it Recyclable matter (like plastic) and hard material like bricks or stone are removed next Kitchen waste sent for composting Combustible matter that remains is fuel taken to boiler to generate steam Steam is fed to the turbine to generate power Pollution abatement system incorporated in boiler, which produces clean energy From 1,000 tonnes of garbage, about 400 tonnes of green fuel is finally obtained.

Set up rooftop solar panels and get paid

Install a solar panel on your rooftop to generate energy and sell it to the distribution company through the grid for money.

To encourage green energy, the Centre is planning a programme under which it will provide incentives, either financial or through a subsidy, to home owners installing a rooftop solar panel for own energy consumption, and who will sell the extra power to the grid during daytime.

The programme also contains a proposal in which a building owner can rent his rooftop to investors to set up a solar power plant.

The plan, which is still in a preliminary stage, says the electricity distribution companies can buy the power from households, either by paying money to the seller or giving subsidy in the seller’s electricity bill.

To introduce the system in India, which is prevalent in many European countries including Germany, there is a need to modify the current Electricity Act as well as develop locally suited technology, Union Minister of Power K C Venugopal told Deccan Herald.

Delhi to be first

The Delhi government is likely to be the first to implement the scheme as the government has started working on the issue. As per the Delhi Government’s proposed policy, residents can get solar power plants installed on their rooftops by signing a power purchase agreement with the company supplying power in their respective areas.

The cost of setting up such a plant in an area of 200 square metres will be between Rs 8 lakh and Rs 9 lakh.

According to the policy, house owners can either lease out their roofs to a developer, who will then set up the unit, or pay 30 per cent of the cost of installation.

The remaining 70 per cent will be financed through banks. The cost of generating each unit of power from the rooftop plant will be Rs 17.50 which the owner of the rooftop can sell to any of the power supplying companies.

The plants will be set up using the solar photo-voltaic technology as they can be easily mounted on rooftops, said an official in the Power Ministry.

The Centre which aims to produce 10,000 MW of solar energy in the 12th five year plan ( 2012-2017) with an investment of Rs 50,000 crore, has already set up 61 solar energy monitoring units across the country.

The government has started collecting radiation data from these monitoring centres and accordingly it will encourage setting up solar plants, he said.

While Gujarat and Rajasthan are ahead with installed capacity of 3,000 MW and 1,000 MW solar energy, the Centre wants other states to follow suit.

Power is money

* A house owner can install solar panel on the rooftop to meet his power needs

* He can then sell the extra power generated to distribution companies

* The owner can also rent out the space for setting up a solar power plant

* In return, discoms will either pay in cash or give subsidy in the seller’s electricity bill

Philips India to export solar LED street lights

Consumer electronics firm Philips will export solar LED street lights, which it has developed in India, to neighbouring nations within next one year.

The company’s Indian arm, Philips Electronics India, is currently executing a project for installing 19,000 solar LED street lights in Tamil Nadu in association with Tata Power Solar and Su-kam.

“Solar is a very efficient mode of energy. The technology for solar LED street lights were developed in India and for India,” Philips Electronics India President (Lighting India) Nirupam Sahay told PTI.
The company has designed and developed the technology at its R&D centre at Noida keeping in mind the rural market, which has a big potential as electrification has not yet touched large number of villages across the country, he added.

“We are just executing about 19,000 such street lights in Tamil Nadu and we are talking to more state governments on this front. These lights have big scope in cities also,” he said without sharing details.
When asked if the company would be interested to supply the technology to Philips’ operations in other nations, Sahay said: “We are a global company. We (Indian operations) handle Nepal, Bangladesh and Sri Lanka. Within next one year, solar LED technology will go out of India, first to the neighbouring countries and later to other parts of the world.”

He, however, declined to share details such as which would be the first export market for this technology.
Elaborating the technology, Sahay said the company develops and manufactures the electronics and LED lights.

“We do not make the panels and batteries. For these, we have worked with Tata Power Solar and Su-kam for the Tamil Nadu project,” he added.

The technology helps the company with options to connect each light post with a single battery or a set of street lights can be run from a centrally controlled solar panel and battery, Sahay said.

On whether the company would continue the relationship with its current partners, he said it would depend on the nature of the future project and customer.

When asked about the company’s revenue expectation from the LED division, he declined to comment saying India is moving towards “white solar street lights”.

“The entire Indian lighting market is estimated to be Rs 9,000 crore and we enjoy 30 per cent share of it. We are in the premium segment,” Sahay said.

Solar power will achieve grid parity by end of the 12th Plan in 2017

Power produced by solar plants will be sold at the same price as that from conventional sources like coal by 2017, a power ministry official said.

“Solar power is very close to achieving grid parity. It will achieve grid parity by end of the 12th Plan in 2017,” Tarun Kapoor, joint secretary in the new and renewable energy ministry, announced at a conference here on the Indian power industry.

“Consequent to the launch of the government’s solar mission in 2010, we see large volumes (of electricity) coming into the sector and we’ve seen prices come down drastically,” Kapoor said.

Outlining the sequence of fall in tariffs, Kapoor informed the conference that from an initial tariff of Rs.17 per kilowatt (kw) hour fixed by the regulator, subsequent tenders had yielded lower average tariffs, and the last tender floated had fetched the tariff of Rs7.49 per kw hour.

“Odisha did a tender and got a tariff of Rs.7 per kw hour to be constant for the next 25 years. This tariff is fixed for 25 years and is better than that from coal, for instance, where new coal based plants using imported coal would charge Rs.5-6 and domestic coal fired ones would charge Rs.3-4. Then as fuel costs rise, tariffs would also go up.”

Kapoor explained that the objective of the solar mission was to increase electricity volumes from solar energy, thereby bringing down prices and demonstrate that solar power is a very good alternative.

“Solar power plants can be set up anywhere (in India) as the insulation is pretty good almost everywhere. The investment required for 20,000 MW capacity would be around Rs. 200,000 crore,” Kapoor said.

India’s JNNSM: Projects under batch II are a “risky” proposition

Many of the batch II solar projects under Phase I of India’s Jawaharlal Nehru National Solar Mission (JNNSM) have been deemed a risky proposition in a new research report by India-based CRISIL Research.

The organization stated that falling photovoltaic module prices and overcapacity “led by Chinese module suppliers” have impacted heavily on capital costs for projects. “In 2011, the capital costs of Solar Photovoltaic (PV) projects fell by 30 percent, following a 50 percent decline in the prices of solar PV modules,” wrote the analysts.
They said, however, that due to the “sharp” margin erosion this prompted, combined with increasing industry consolidation, module price drops are expected to slow this year, meaning that capital costs should decline by just 10 to 13 percent, to INR 87 million (around €1.2 million; US$1.6 million) to INR 90 million per megawatt this year.
However, anticipating bigger decreases, some project developers submitted “aggressive” bids to the JNNSM’s Phase I Batch II program – as low as INR 7.49 (around €0.10; US$0.13 ) per Watt, said CRISIL – which will place pressure on their margins unless they can access low-cost foreign debt.
“For healthy equity internal rate of returns (IRRs) of around 15 percent, a levelised tariff of Rs 9 per unit is necessary, assuming a plant load factor of 19 percent and typical debt equity of 70:30, with borrowing costs of nearly 13 percent,” stated the report. However, as around half of the bids have been below Rs 9 per unit, many of the investments are “highly risky”.
Financing the projects at INR 9.00 and below will be a great obstacle for the power producers, believes CRISIL.
It added that while it is possible these projects can be financially viable, if project developers tap cheaper foreign funds – foreign developmental finance institutions may provide low cost debt to solar power producers so that they purchase solar equipment from suppliers in their country – there are two factors in India, which are working against this: (i) the domestic procurement clause imposed by JNNSM for crystalline PV cells and modules, which is limiting access to such funds; and (ii) the INR is gaining traction against the U.S. dollar, thus making borrowing in dollars is an increasingly risky proposition.
Comparison of batch I and batch II bidding
French company, Solairedirect was the lowest bidder for a five megawatt (MW) project under batch II of the JNNSM, at INR 7.49. Meanwhile, the highest bid under this batch, INR 9.44, was from Green Infra. Looking to batch I, INR 10.90 was the lowest tariff quoted by bidders. While higher than the bids from batch II, this figure created controversy at the time, with industry insiders skeptical that such a low bid could turn a profit.
Overall, the average tariff dipped downward by 27.5 percent in batch II, compared to batch I. The table below shows the successful bids for photovoltaic projects under batch II, which ranged from INR 7.49 per kilowatt hour (/kWh) to INR9.39/kWh. Meanwhile, in batch I, the value varied from INR 10.95/kWh to INR 12.76/kWh, with an average bid price of INR 12.15/kWh.
