Parent Project

Commercialisation of solar energy in urban and industrial areas (ComSolar)

Commissioned by:

German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB)



Lead executing agency:

Ministry of New and Renewable Energy, Government of India (MNRE)

Overall term:

2009 to 2013 (Part-wise extension till 2016)


The Jawaharlal Nehru National Solar Mission (JNNSM) has set the ambitious goal for India of achieving 22 GW (revised to 100GW) of solar energy capacity by the end of 2022. It aims to create an enabling policy framework that attracts industry to invest in solar energy applications. The Government of India's Ministry of New and Renewable Energy had a focus on development of large scale solar power generation projects under Phase I of JNNSM to bring down the cost as well as to build appropriate know-how. In the Phase II of JNNSM, the Ministry is focusing on penetrating rooftop solar photovoltaic projects in various States.

To facilitate the commercialisation of solar energy in urban and industrial areas, it is necessary to run few successful pilot projects and create a regulatory framework that includes appropriate feed-in tariff or net metering schemes. The project ComSolar commissioned by German Government under its international climate initiative is implemented by GIZ in cooperation with Ministry of New and Renewable Energy (MNRE), Govt. of India, to promote solar energy in the country.


ComSolar follows unique multi-pronged approach wherein demonstration projects are installed based on successful business models, a positive and balanced policy/regulatory framework is designed in partnership with the central and state government while disseminating the knowledge and experience to trigger further replication of business models tested. The approach has shown encouraging results and indicators of developing the solar market in India.

Focus areas

ComSolar has mainly two focus areas i.e., the rooftop photovoltaic solar segment and solar thermal technology for industrial process heat sector. Two additional innovative sub-projects “solar space heating in Ladakh (Himalaya) region” and “India One” a 3.5MWth solar thermal power plant based on concentrating dish technology with thermal storage were added to the portfolio.
