At least 20 resident welfare offices in the New Delhi district will soon be powered by the sun. A proposal has been approved for a pilot project under which porta cabins provided by the government to RWAs for office use will have rooftop solar panels. The initial planned solar capacity is 20 kW and is expected to be increased as more areas will be brought under the ambit of the project.
A list of 20 locations has been identified but a final list will be prepared once feasibility of each location is confirmed. “The project will be funded entirely under the ‘My Delhi, I Care’ scheme of Delhi government.
RWAs had been given porta cabins but many of them were finding it hard to function without provision for power. Some have taken up independent connections but are finding it hard to pay bills. The government then stepped in with the proposal for roof-top solar panels. This is the only district in the city with such a provision,” said Nila Mohanan, deputy commissioner, New Delhi. The project will be set up by discom Tata Power Delhi Distribution Limited (TPDDL). Its CEO and executive director Praveer Sinha said that it would be implemented within the next two to four months.
“Each porta cabin will have a 1 kW capacity system which takes the total project up to 20 kW. Each unit will be able to run at least a fan, a tube light and a television with this much supply. If the project is successful, it will be expanded to cover more areas. The power generated through the panels will be free for the users as they will be stand alone arrangements. Each system will cost roughly Rs 1.5 lakh,” said Sinha.
Sources said that a total of Rs 1 crore has been allocated for the project though the initial expenditure would be about Rs 30 lakh. “The remaining amount will be kept aside for the expansion of this project. Roughly 50-odd locations can be covered under this system eventually,” said sources.
Meanwhile, even though Delhi’s renewable power obligation has been identified, sources said that it would take another two to three years at least for it to be implemented by the discoms.

Now it is time for the rooftop solar power plant in India, explained by the many speakers at REaction, 3-day conference organized by Energy Alternatives India it was a conference of the renewable energy industry and EAI is a Chennai-based clean-tech consultancy.
The Managing Director of SunEdison, Mr Pashupathy Gopalan, said solar plants on rooftops of commercial buildings can even now produce power at costs almost equal to distribution company rates and the grid parity of the residential rooftops will be reached within two years.
It doesn’t matter even if policy-makers do nothing to push rooftop solar. “Economics will take over,” Mr Gopalan said. he has further said that it is feasible to sell roof top solar electricity at Rs. 7 per unit. SunEdison has already put up a Solar roof-top plant of 100KW on the roof of SCOPE, Standard Charter Bank’s captive BPO in Chennai but it has npt disclosed at what price they are selling the electricity.
The biggest advantage in this rooftop solar installation is that electricity prices are fixed for approximately 30 years, even if grid power is a trifle cheaper today but it is sure that the prices of the grid power are going to rise.
Raising funds typically is the most critical aspect about residential rooftop projects in India, as the households find it difficult to raise funds from banks, we know that all the households are not inclined to incur capital expenditure for electricity that is anyway available from the grid said by Mr Gopalan.
The per unit cost of a rooftop solar plant production with battery base storage is Rs 10 but without battery backup, the cost would be much less, told by Mr Madhavan Nampoothiri, Founder and Director, RESOLVE Energy Consultants.
There are some facts about the solar rooftop which must be known which are as that a rooftop solar plant with “grid-tie” will not need battery back-up, but the solar plant will stop functioning if the grid goes off. However, if a diesel genset is used as a back-up for periods when grid power fails, solar power could be harnessed the most, said Mr Rajeev Agarwal, Founder & Managing Director of Ardor Green Solar and Wind Pvt Ltd.
The data made available by MNRE now shows that solar PV installations in India have crossed the 1000MW or 1 GW capacity.
Grid interactive solar PV installed capacity was 1,030.66 MW by the end of June. Most of the capacities have come in Gujarat. Local use of solar energy has also undergone much height. The figure shows that India has 85.21 MW of off-grid solar PV systems with system capacity of at least 1KW.
Talking of the overall renewable energy installations in India total grid interactive renewable energy installations crossed 25,000 MW in the first quarter of the current year.
During the first quarter of the year, 291.7MW of the 495MW added was from wind energy sector in the first quarter of the year.
At present the total installed capacity of renewable power plants in the country is 25,409 MW.
Target for 2012-13
The Ministry has set a target of 4,125 MW of additional green power capacity for the current financial year. This includes 2,500 MW of wind power and 800 MW of solar PV.
It is worthy of note that the targeted wind power capacity is lesser than the achievement of last year, which was 3,164 MW.
When noted the views from the wind energy sector that even 2,500 MW would be a tough target to achieve, due to two reasons. The reasons being counted are removal of two key benefits i.e. ‘accelerated depreciation’ and ‘generation-based incentive’. The tough operating condition in the chief operating states like Tamil Nadu is also seen as a barrier for achieving the targets.
In a conference REaction key speakers indicated for rooftop solar to grow in a big way in the coming time. Solar plants on rooftops of commercial buildings can even now produce power at costs almost equal to distribution company rates said Mr Pashupathy Gopalan, MD, SunEdison.
Adding he said residential rooftops will reach grid parity within two years.
It doesn’t matter even if policy-makers do nothing to push rooftop solar. “Economics will take over,” Mr Gopalan said.
He also said that it is feasible to sell rooftop solar electricity at around Rs 7 a unit. Grid power is cheaper at present but will go up in future. Comparing, the biggest advantage in this is that electricity prices are fixed for, say, 30 years. For a typical household the difficulty is to incur expenditure on solar although electricity is available from the grid. But even if they wish to go for the loan it is difficult to obtain from the banks.
Mr Madhavan Nampoothiri, Founder and Director, RESOLVE Energy Consultants, said it is Rs 10 to produce a unit of battery based rooftop solar power. The cost will be much less if the electricity is much cheaper.
A grid-tied system does not need battery back-up, but will stop functioning as the grid goes off. However, where a diesel generator is used as a back-up for periods when grid power fails, solar power could be harnessed the most, said Mr Rajeev Agarwal, Founder & Managing Director, Ardor Green Solar and Wind Pvt Ltd.

Finally the bells are ringing in the Delhi Electricity Regulatory Commission to alert them about the Renewable Sources of Energies available abundantly. According to an article in Times Of India the DERC will be announcing a 2% renewable energy obligation (RPO) for Delhi discoms (Source: Times of India). This move will make it mandatory for the discoms to provide 2% power through renewable energy resources including wind, solar, municipal waste etc.
Solar Energy seems to grab the attention of the authorities now as the new regulation will mandate at least 0.1% solar power among various other sources. Delhi government will be in line with other state governments such as Gujarat, Maharashtra and Rajasthan who are already producing a good amount of renewable energy. However there seems to be some doubts among the consumers relating to the costly proposition of solar market but with the drastic decrease in the per unit rates of solar energy from Rs. 18 per unit to current Rs. 8-9 per unit the stakeholders can find some relief following the national solar mission of the country. The execution can be divided into several phases and also can be done through Roof-top policy which has to be decided by the decision makers. The people just have to wait and see when and how is the policy implemented for a cleaner, greener society.
