The international Energy Agency (IEA) founded in November 1974, is an autonomous body <z60E vHg
within the framework of the Organisation for Economic Co-operation and Development MA9E??p3\
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 Z~(X[Zl
:
member countries. The European Commission also participates in the work of the Agency. SD~4CtlfI
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D i ,~(_|-r
agreements established within the IEA, and since 1993, its Participants have been conducting a xH28\]F5n
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ,]JIp~=nsh
electricity. !c k luj
The Overall programme is headed by an Executive Committee composed of one representative F&p42!"
from each participating country, while the management of individual research projects (Tasks) q@S \R

is the responsibility of Operating Agents. Currently nine Tasks have been established in the _~1O #*|4

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, {7X9P<<L7
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ci? \W6
systems will continue to represent a significant PV market segment, not only in developing u-.5rH l
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ORX<ZO t1
countries are sharing their experiences in this area. Q g1kF^=
This battery guide is intended for a wide use also close to the end customers to increase the V`/c# y||
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ,,j > 2Ts
cost for battery storage in small stand alone photovoltaic systems. Also some basic $5ea[n c
environmental concerns are addressed. The report has been prepared under the supervision of .+8#&Uy
