Dairies can now be run on Solar Power


Dairy owners used to worry on the unscheduled load shedding during summer or if not that then from bad power quality of electricity supply. They then used do to run diesel generator or use labour for milking their cows and buffaloes at their farms giving them high bills.

On the USP of elimination of noise and cost saving a milking machines operated on solar power is launched. It will now be reducing the electricity bills and labour costs.

“It will be useful for small and medium dairy owners. It is priced at Rs 70,000 and is eligible for subsidy from Karnataka Milk Federation. The quantity of the subsidy varies from one milk producers’ association to the other in the state since each of them has its own norms and rules. A dairy farmer who buys this battery-operated milking machine is eligible for subsidy between Rs25,000 to Rs40,000,’’ said BG Santosh, Sales Manager, Siddon Biotech a Bangalore based company providing solutions in the field of animal nutrition care.

The viability of it comes for them more who uses diesel generator . Other advantages of it is that It is an easy to go machine as it is a trolley-mounted and it has a provision of auxiliary supply from electricity. The machine was brought in limelight during the AgriTech India 2012 in Bangalore.

50 MW 5 phased project in pipieline in Bihar

A US-based agency, Schanti Partners, New York will be developing 50MW project worth Rs 580 crore for a solar energy project in Kaimur district of Bihar. Initially, a 10MW unit would be setup. They have received approval letter from Bihar State Investment Promotion Board, no-objection letter from Bihar Renewable Energy Development Agency (BREDA),and the proposal is submitted to Bihar State Electricity Board (BSEB).

Intention is to have a 12.5Rs/unit PPA of 25 years with BSEB.

A fully-owned subsidiary of Schanti Partners LLC ‘Sparkle Solar Bihar I’ will be executing the project. The project will be developed in a phase of 10 MW in 5 phases. The equipment would be sourced from Sol Focus Inc. , a US solar equipment manufacturer. An official marking the importance of project said “With the setting up of this solar energy plant, Bihar will emerge as a leader in solar energy development among eastern states of India”.

The project will use the most recent version of photovoltaic technology called Concentrating Photovoltaic (CPV) system; it is the PV technology with an optical system that focuses sunlight over a large area onto each cell.

The agency would not be taking help from Bihar industrial land bank. As per the proposal, the land would be leased for 30 years term directly from the owners, in lieu of annual lease payments to them.

The financing for the project has already been secured, with a letter of intent(LOI) from the Export-Import Bank of the US. The letter of intent provides for approximately $30 million in financial support with factors depending on extent of US-made solar power equipment.

Kaimur district has robust electricity infrastructure for power evacuation, with grid connectivity and nearby electrical substations. Power lines of 33kV and 132kV and electrical substations are already in place in the district.

Allocation of 175MW of grid-connected solar power projects was granted last year by Bihar Solar Policy.

BEST going to reduce energy bills through Solar PV


BEST undertaking has decided to deploy solar power on an experimental basis to provide electricity to its 25 bus depots across the city.

BEST bus depots have lakhs of rupees electricity bills annually, more of for western and eastern suburbs. A senior official said “Electricity is needed to light up the depot almost round the clock, to run various equipment to maintain and clean buses and at the various offices within the depots”. First 3 depots will be run on solar. “We will gradually shift to solar energy at all the depots”, the official stated. Although not officially announced but as per the sources BEST would begin with depots in the suburbs and gradually include other prominent depots like Colaba and Backbay in south Mumbai in the second phase.

BEST General Manager Om Prakash Gupta said, “We are keen on experimenting with solar power. We will invite bids from parties willing to provide the service to us. As a pilot project, we will start with three depots”. It was Mr Ravi Raja, BEST committee member who at a recent committee meeting suggested that BEST should install solar panels at the depots. He said, “In the suburbs, we purchase power from RInfra at a very high cost. If we switch to solar power, the initial investment could be costly, but we will save a lot of money in the long run.”

A discussion for inclusion of LED also took place where BEST panel Chairperson Ashok Patil suggested in its favour for obtaining 60% power saving. However, Gupta said that they were not “cost-effective” when tried over few depots

The BEST 25 depots across the city are used for parking the fleet of 4,680 buses.


4337 solar lanterns would be distributed to the shepherds of Himachal Pradesh by the state Government

Indian Solar Manufacturers facing a tough time with US Fast Start Finance policy


According to the CSE (the Delhi-based Centre for Science and Environment) says that the Indian solar panel industry is being killed by the conditions placed by the US as part of its initiative on climate fast-start finance.

The Indian developers are having the opportunity of getting loans at very low interest rates from the US Exim Bank and the Overseas Private Investment Corporation if the equipment, solar panels and cells are sourced from US companies, according to the CSE.

Mr Chandra Bhushan, deputy director (CSE) says that the result of this is that most of the orders are being bagged by US companies rather than local manufacturers, putting the domestic solar photo-voltaic industry at risk.

Mr Chandra Bhushan also spread the light about the Fast start finance, according to Mr Bhushan…

  • Fast start finance is a $30 billion fund set up under the aegis of the United Nations Framework Convention on Climate Change (UNFCC).
  • The fund, adopted at the Copenhagen climate meet in 2009, is meant to help developing nations deal with the impact of climate change and limit greenhouse gas emissions, says Bhushan.

Whereas the US is manipulating this and has been using this fund to promote its own solar manufacturing.

This has distorted the market completely in favour of US companies.”

  • Currently, 80 % of local manufacturers are in a state of forced closure and debt restructuring with no orders coming to them,
  • While the US manufacturers are getting orders from Indian solar power developers, according to the CSE. The Centre has been promoting solar power projects since 2010 as part the National Action Plan on Climate Change.

The Indian Government is also promoting its own manufacturing by giving subsidy to the Indian manufactured products. The good thing is that Indian govt. is not manipulating any UNCC fund for its own benefit as the US is doing.

Indian Govt must take initiative to get its Domestic manufacturing out of this trouble and for the promotion also.

Some of the initiative taken by the Indian govt. and the loophole are explained below

Under The Jawaharlal Nehru National Solar Mission (JNNSM), which plans to install 22,000 MW of solar energy by 2022, It is mandatory that

  • All projects must buy domestically-manufactured equipment,
  •  It only specifies this in the case of crystalline PV technology,
  • This is not applicable fort thin-film PV.
  • According to the CSE researchers this has provided a loophole for the US Exim Bank and OPIC to offer low rates of interest (about 3%) and a long repayment schedule (of up to 18 years) to Indian solar project developers provided they buy thin-film panels manufactured by US companies.

If we see Quality wise the thin films are lower as compared to the crystalline one.

As far as the Indian Banks are concerned the Loans from Indian banks come with an interest rate of close to 14% or more.

This Process of higher loan has skewed the market completely in favour of thin-film panels imported from the US, despite the fact that these are less efficient than crystalline panels.

Almost 60% of panels installed in India are thin-film, while globally its only 14%. This hike in the use of Thin film is mainly due to the easily availability of loans which compromises the quality factor of the panels.

This shows that the continuous use of thin films will surely have an impact on the Clients output and the Perception regarding the Solar efficiency in India.

Might be it is possible that the people lose hope in this sector as this just the beginning in India because the quality output is on stake with the increase use of less efficient panels.

Generation of Power under JNNSM


India has separated targets for 2013 1100MW of grid connected & 20,000 MW by 2022 under the JNNSM, this information was given in written by Dr. Farooq Abdulla the Union Minister of New and Renewable Energy in Rajya Sabha, and the total investment may be approximately $ 40 billion for 20,000 MW of solar power projects.

205340.26 MW is the current installed generation capacity of India which includes

  • 24832.68 MW generated through renewable energy sources.
  • JNNSM aims at achieving 20,000 MW by 2022 thereby it will then constitute one-tenth of India’s current installed power base.
  • The total installed capacity in the country is likely to be more than 400 GW by 2022.
  •  Installed solar capacity then would be one-twentieth of the then India’s total installed capacity.
  • The share of renewable and particularly solar in country’s energy mix would keep increasing and would certainly help in limiting reliance on coal and easing the power deficit.

1030 MW of solar power projects have been commissioned and connected to grid  against a target of 1100 MW of grid connected solar power by 2013, and  these are under both Central and State initiatives according to theThe Minister .

Followings are the steps which are to be taken and the issues to be handled for the completion of the target and projects under the JNNSM by the Govt. & other respected departments

  • like up gradation of transmission network,
  • availability of unallocated power for bundling,
  • delay in payment by DISCOMS,
  • Weak State Nodal Agencies are being focused on.
  •  A transmission network up gradation plan has been prepared by Power Grid Corporation of India Limited.
  • Ministry of Power has been requested for giving unallocated power.
  • Payments from DISCOMS are being monitored continuously and States are being requested to upgrade Nodal Agencies.


All the above information tells us that there are serious steps which are to taken seriously for this growing industry to flourish and for the India to be a Major Player in the field of renewable energy.

Solar variable-frequency drive (VFD), able to run a 3-phase AC motor directly with panels

In Musunuru Mandal of Krishna District for the past three years A solar power unit is producing entire electricity needed for pumping water to raise three crops a year in 13 acres in Katrayanapadu village limits. System Size is 10 kilowatts having 51 solar panels of the unit with a photovoltaic produces enough power to run a 12.5 horse power (HP) motor all through the day.

This is an example of successful pilot project launched here which has come to fruition and the Schneider Electric proposes to go commercial with its solar variable-frequency drive (VFD) which can run a 3-phase AC motor directly with the power generated by the panels. When sky is overcast the motor works at lesser frequency, but still draws water.

Sunbright Energy Solutions Private Limited came up with the idea of using a VFD to use solar power. Company CEO Parvataneni Ramesh toldthat the unit has been working so well that representatives of Schneider Electric that custom built the VFD for them came here to assess the performance.

As we know that in general the PV cells produce DC current therefore only DC (direct current) motors can be used for solar power units but in this case the VFD devise allows use of the solar power for running the existing AC electric motors on fields.

The success of the unit at this village encouraged them to install yet another unit at a 22-acre sweet lime garden in Chatrai mandal. Company vice-president Vikas Jaivanth said that solar energy was clean power that is gaining tremendous importance in the fast emerging global warming scenario.He said the Central government was giving 30 per cent subsidy on such products, but producing the necessary documentation was currently highly cumbersome.

Prabhu S. Nagavi who is managing marketing (Motion and Drives)  at  Schneider Electric said that the company had put the VFDs on trial in different climatic conditions and would launch it commercial on their completion.

Government forcing hard over Energy Conservation Act implementation


The poor implementation of Energy Conservation Act (ECA), 2001, which mandates use of solar water heating systems in buildings in all states has grown concerns from Centre over Odisha Government. Union ministry of urban development asked the states in April 1999 to amend building bylaws for mandatory use of solar water heating systems in “functional” buildings. According to the source there were many reminders sent to the state in this regard. One of the letters to Principal Secretary of Odisha housing and urban development departments says “Solar water heating system can help save electricity and other fossil fuels. It can also prevent load shedding during peak hours”. But till yet it is not implemented

Mr Dilip Routray, senior housing and urban development officer said “the MNRE has sought compliance report of its instruction. We have urged the urban local bodies to incorporate the norm by amending the bylaws. The compliance report would be presented at a national-level workshop later this month in New Delhi”. Task of coordinating it with the municipal corporations and municipalities in the state is with the Directorate of Town Planning. “The building bylaw is being amended and would be completed soon. We will surely abide by the Central directive,” Director, town planning, P K Patnaik said.

The Centre has engaged two consultancies which would help in implementing ECA. For its implementation in urban local bodies there are two Centre appointed consultancies. Municipal Corporations will also be guided in modifying the model regulations and bylaws. For sensitizing the stakeholders, very soon agencies will be organizing workshop on significance of solar energy in Odisha.

Meanwhile, as Bhubaneswar is among 60 cities of India identified for developing as solar cities, the Bhubaneswar Municipal Corporation is in the process of making it so. MNRE would bear the entire cost of the Rs 37.37 lakh project. Under the project, at least 10% of the projected demand of conventional energy would be reduced through renewable energy installations. For this buildings will be categorised into residential apartments, commercial complexes, industries, individual houses, corporate establishments and government buildings. With an aim to reduce 40% of the energy demand LED street lighting has been launched at some places of the city.

Noida traffic lights going solar


The traffic light of Noida are planned to be solarised within 2 weeks time span. As the traffic snarls were found to be increasing the growing concern made Noida Authority and the district traffic police to minimize this. Presently 38 of the total 79 signals are powered by solar energy.

The plan was initially proposed about 5 years back and about 25 traffic signals maintained by the Authority were powered by solar energy at that time. The matter of extending was recently approved in the Authority’s board meeting. The final outcome may be out within a fortnight. The main reason is the recent collapse of major power grids and the resultant failure of traffic signals. Therefore authorities have decided to take a step forward to ensure a “100 percent power back-up arrangement.”

On the matter Mr Sanjiv Saran, CEO, Noida Authority said “Frequent power disruption in Noida often leads to non-functioning of traffic signals at various intersections causing inconvenience to both commuters as well as the traffic police. Once all signals are run by solar energy, this problem will be solved”. Sun being the source of energy therefore the system can be lighted uninterruptedly thus preventing traffic chaos.. The cost of converting a traffic signal into a solar powered one is between Rs12 lakh and Rs15 lakh. However, this is much more than the cost of installing a regular traffic signal. But in the long run, solar panels offer significant savings on energy consumption and cost Adding saran said “These are easy to maintain and eventually they turn out to be more economical,”

Meanwhile, to streamline traffic flow, “particularly during peak hours,” traffic police is proposing to upgrade computerized area traffic control system.
