Our profile
Owned by the Federal Republic of Germany
Operations in Germany and in over 130 countries around the world
Around 17,000 employees
Operates in India since 60 years, currently 250 staff members in India
GIZ is working in areas in which demand in India’s emerging economy is high and in which Germany is particularly strong.
GIZ is a German federal enterprise.
The sole shareholder of GIZ is the Federal Republic of Germany, which is represented by the Federal Ministry for Economic Cooperation and Development (BMZ) and the Federal Ministry of Finance (BMF).
GIZ is organised as a private-sector entity and can be contracted directly. The Management Board, the Shareholder and the Supervisory Board are the three organs required under German law for a GmbH (roughly equivalent to a limited liability company). The Chair of GIZ’s Management Board is Tanja Gönner. GIZ has a five-strong Management Board, with Tanja Gönner, Christoph Beier (Vice-Chair of the Management Board), Tom Pätz, Hans-Joachim Preuß and Cornelia Richter.
GIZ supports the German Government in achieving its objectives in the field of international cooperation for sustainable development. To put it another way: GIZ is a federal enterprise which supports change – for Germany – around the world.

3. GIZ project “ComSolar”
Implemented by
GIZ project “ComSolar”
Objective is to develop and demonstrate viable models for commercialisation of solar energy in urban and industrial areas in India
Part of the International Climate Initiative (ICI) of the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB)
100% financed by German government / ICI with the objective to support partner countries for climate protection
ComSolar is based on a bilateral implementation agreement between the Governments of India and Germany (MNRE & GIZ)
ComSolar/GIZ has been supporting DMRC to implement first light- house PV rooftop project

Implemented by
Key figures for Rooftop solar electricity
Numbers for 1 kW PV system
Area required
8-12 sq.m
Electricity Generation
Approx kWh/year
Life of the PV modules
Normally guaranteed for 25 years
Typical Costs
Without battery costs about INR 80,000 - INR 1,00,000*. Larger the system size, less is the per kWp price.
Government incentives
Ministry of New and Renewable Energy now provides 15% capital cost subsidy depending on schemes and budget**.
Savings/Payback
The cost is mostly recovered in 6-8 years

8. How much PV capacity should you install?
Implemented by
How much PV capacity should you install?
Depends on lot of factors e.g.,
Objectives - Meet internal consumption or install maximum as much as you can
Internal electricity demand (load curves)
Available finances?
Technical details of the roof
Load bearing capacity, area available, orientation, shadow causing objects etc
Government policies - Is net metering allowed? What are the regulations in the state?

17. Environmental and Social benefits
Implemented by
Environmental and Social benefits
Reduction in CO2 emissions
1kWp rooftop solar plant saves about 1 tonne of CO2 emissions every year.
Saves transmission and distribution losses
Rooftop solar also saves electricity which is lost in long transmission and distribution lines
Green local value creation
Creation of jobs (e.g. local installers), generation of local tax and lease revenues – all without producing any emissions
