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 2016
Project team: Implementation by team of local and international experts based at GIZ New Delhi  


The Jawaharlal Nehru National Solar Mission (JNNSM) in 2010 had set a goal to achieve 22 GW of solar energy capacity by the end of 2022. The mission aims to create an enabling policy framework that attracts industry to invest in solar energy applications. The Ministry of New and Renewable Energy had a focus on development of large scale solar power generation projects. In phase I, the objective was to bring down the cost as well as to build appropriate know-how. In 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 a 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 the Ministry of New and Renewable Energy (MNRE), Govt. of India, to promote solar energy in the country. After 5 years from the launch of the mission, the Government of India have stepped up the targets under the mission to now achieve 100 GW Grid Connected Solar Power by 2022. The target will principally comprise of 40 GW Rooftop solar and 60 GW through Large and Medium Scale Grid Connected Solar Power Projects.

To facilitate the commercialisation of solar energy in urban and industrial areas through development and demonstration of innovative business models for solar energy applications in urban and industrial sectors/areas. 

In a multi-level approach, the project is piloting successful business models at the same time as it interacts at the policy level to help improve the regulatory framework:

  • Demonstration projects – Commercial projects having good replication potential and significant CO2 reduction scope are being implemented with high level of commitment from the partners involved.
  • Supporting regulative framework  Policy advisory and support to contribute to an establishment of the required regulatory framework, as this is one of the main prerequisite for the promotion of solar power systems.
  • Capacity & awareness building – The project organises specific training programmes, including seminars, study trips allowing relevant groups to enhance their skills.

Focus areas
ComSolar is working primarily in the area of rooftop photovoltaic and solar thermal process heat for industrial applications.

ComSolar activities


ComSolar is piloting innovative solar technologies and business models in order to test and assess the technical and economic feasibility of these energy solutions and then developing strategies for replication and dissemination. (more)


ComSolar is supporting MNRE and state nodal agencies in exploring various feasible and replicable mechanisms for the deployment of grid connected rooftop solar photovoltaic facilities and to design suitable implementation framework. (more) 


ComSolar supports its partners and other stakeholders such as the developers and financing entities with successful capacity building measures and tools (e.g. Solar Guidelines). (more)
