Earlier this month, SolarIndiaOnline reported about Solar Mission plans to install 20,000MW capacity by 2020 in the story “Renewable is not an alternative anymore”.
Ministry has finalized the draft for the National Solar Mission. After the first initiative of installing generation capacity of 50MW through Solar, the ministry has now gone all the way, to make Solar a valuable option for Indian Power Industry. SolarIndiaOnline.com earlier this month announced about the plan of ministry to install solar generation capacity of 20,000MW by 2020. According to draft agreement by Ministry, the plans are to install solar generation capacity of 20,000 MW by 2020, of 1,00,000 MW by 2030 and of 2,00,000 MW by 2050.
The total expected funding from the government for the 30-year period will run to Rs. 85,000 crore to Rs. 105,000 crore. The requirement during the current Five Year Plan is estimated to be Rs. 5,000 crore to Rs. 6,000 crore. It will rise to between Rs. 12,000 crore and Rs. 15,000 crore during the 12th Five Year Plan.
The plan till 2020 will take be implemented in three phases.
The First Phase: 2009-2012: The Ministry will focus on expansion of on-going projects for urban, rural and off-grid applications. This will involve the promotion of commercial-scale solar utility plants, mandated installation of solar rooftop or on-site photo-voltaic applications in buildings and establishments of government and public sector undertakings.
In this phase, the Mission will make it mandatory for all functional buildings such as hospitals, hotels, guest houses and nursing homes to install solar water heaters. Residential complexes with a minimum plot area of 500 sq m will also be included. Expansion of solar lighting systems through market initiatives including micro-financing, in the rural and urban sectors, is expected to provide access to lighting for three million households by 2012.
The Second Phase: 2012 and 2017: Mission will focus on the commercial deployment of solar thermal power plants. This will involve storage options, and the promotion of solar lighting and heating systems on a large scale in market mode. This will be without subsidies but could include micro-financing options.
The Third Phase: 2017 and 2020: The target is to achieve tariff parity with conventional grid power and achieve an installed capacity of 20 gigawatts (Gw) by 2020. The installation of one million rooftop systems with an average capacity of 3 kilowatts (kW) by the same year is also envisaged.
The strategy will be to achieve the target along with reducing the cost of these projects. However there has been no confirmation from the ministry on this. The original may have few changes.

Proposal to introduce solar invertors
Source: http://www.thehindu.com/2009/04/07/stories/2009040754270400.htm
The Delhi Government’s power department is mulling over a proposal to introduce solar panels for recharging batteries used to run appliances of everyday use during power cuts and outages. The proposal comes at a time when the department has been stressing the need to use more green energy and reduce dependence on non-renewable energy.
An official of the power department said the concept is similar to that of a solar water heater. “Solar panels are used to draw the energy of the sun to run appliances just like an inverter does. While an inverter uses energy from the grid to recharge the battery, here the battery gets recharged from solar energy, which is clean and economical,” he said.
The proposal to use solar energy to run the inverter has been put forth by Moserbaer Photo Voltaic, a company that manufactures photovoltaic products.
Explaining the concept, the company’s general manager Gagan Vermani said: “The idea is to utilise solar energy at the level of smaller consumers as well. We usually see the use of solar energy in villages and at large scale. Also the accent has been on solar water heating, which is required for a relatively shorter period, therefore we made this suggestion to introduce solar modules for charging inverter batteries.”
The system will allow consumers to pick the size of the modules as per their requirement and save on their energy bills. “The battery here will not require power from the grid to recharge; it will get re-energised even as it is being used from the solar modules attached to it. Apart from the initial investment (the cost of modules) the system does not incur any running costs,” said Mr. Vermani.
A 100-Watt module for instance requires a space of one metre square in dimension and costs about Rs.15,000. “All it (modules) requires is a bit of cleaning once every few days so that the efficiency does not go down. The modules last for as long as 25 years”. To make the concept economically viable for consumers, the company has also proposed extending a subsidy to the buyers. “To popularise solar water heating the government offers a subsidy to consumers. A similar formula should be worked out for the solar invertors as well, inverters are used in all kinds of weather and definitely more than the water heaters,” he said. Owing to the gap in the demand and supply of power in the city and its suburbs, the sale of invertors has been on the rise over the years. The ASSOCHAM in 2008 had forecast a 30-35 per cent hike in the demand for inverters, their batteries and generator sets.
