utilization of the system

25.01.2012 Seite 4Page 4

Overview

Background

Installed 50 PV 1.43KWp systems (Phase 1A) and

are operational since 2008

Installed 50 PV 1.7KWp systems(Phase 1B)

The systems are distributed in nine regional states

based on the Federal resource distribution method

8 local companies have installed the PV systems

Installation is supervised by GIZ-ECO

All installations are performed as per the preset

minimum standard
