The international Energy Agency (IEA) founded in November 1974, is an autonomous body Z:I*y7V-

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D E9^(0\Z

agreements established within the IEA, and since 1993, its Participants have been conducting a n`P`yb\f$
variety of joint projects in the applications of Photovoltaic conversion of solar energy into E;9Z\?P

The Overall programme is headed by an Executive Committee composed of one representative f ucUwf\_
from each participating country, while the management of individual research projects (Tasks) 66oK3%[
is the responsibility of Operating Agents. Currently nine Tasks have been established in the M[A-1]'

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, mRCHrw?WG
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV d{W}p~UbH
systems will continue to represent a significant PV market segment, not only in developing [u[ U_g*
countries, but also in the important home markets of industrial countries. Experts from 15 IEA GOGt?iw*<
countries are sharing their experiences in this area. i#k-)N _$
This battery guide is intended for a wide use also close to the end customers to increase the ]x2Jpk99a
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle pP3U, n
cost for battery storage in small stand alone photovoltaic systems. Also some basic x7f:F.
environmental concerns are addressed. The report has been prepared under the supervision of
