The international Energy Agency (IEA) founded in November 1974, is an autonomous body 'z5 ;o :T
within the framework of the Organisation for Economic Co-operation and Development 2yc\A3ft#
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 g8y Zc}4
member countries. The European Commission also participates in the work of the Agency. j*

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D xGPv3TLH^
agreements established within the IEA, and since 1993, its Participants have been conducting a 7w({ GZ
variety of joint projects in the applications of Photovoltaic conversion of solar energy into gI{F"7fa=
electricity. *E 6 p=
The Overall programme is headed by an Executive Committee composed of one representative x7>sy,c
from each participating country, while the management of individual research projects (Tasks) ArM e[t0$
is the responsibility of Operating Agents. Currently nine Tasks have been established in the
/n=/WGl
IEA PVPS programme. Z)0R$j`2

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, \t3i9#Q
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV Pr' py
systems will continue to represent a significant PV market segment, not only in developing $>Do&TU
countries, but also in the important home markets of industrial countries. Experts from 15 IEA W=+ ag<@
countries are sharing their experiences in this area. F "I@=R-n
This battery guide is intended for a wide use also close to the end customers to increase the -K4RQ{=>UZ
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 1+zax*gO-
cost for battery storage in small stand alone photovoltaic systems. Also some basic Fx 2&ji6u
environmental concerns are addressed. The report has been prepared under the supervision of J3v uh#
