The international Energy Agency (IEA) founded in November 1974, is an autonomous body g#^|oYuH6
within the framework of the Organisation for Economic Co-operation and Development 64ox jF)
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 HQVh+ (
member countries. The European Commission also participates in the work of the Agency. VC&c)X
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D '8Wv.X0`
agreements established within the IEA, and since 1993, its Participants have been conducting a 9w ~cvlv[
variety of joint projects in the applications of Photovoltaic conversion of solar energy into NGzgLSm\
electricity. $% qg"
The Overall programme is headed by an Executive Committee composed of one representative LVtu*k
from each participating country, while the management of individual research projects (Tasks) kl7A^0Qrz
is the responsibility of Operating Agents. Currently nine Tasks have been established in the L ^Y3=1#"g
IEA PVPS programme. y%(X+E"n*

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, )^; DGzG
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV vE\lp8 j+
systems will continue to represent a significant PV market segment, not only in developing [B /0-(?
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 4,1oU|fz
countries are sharing their experiences in this area. mBl7{w;Iv
This battery guide is intended for a wide use also close to the end customers to increase the o" _=K%9
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle UVX"fZ)
cost for battery storage in small stand alone photovoltaic systems. Also some basic +uQB
