The international Energy Agency (IEA) founded in November 1974, is an autonomous body {XAKf_Cg
within the framework of the Organisation for Economic Co-operation and Development T
&1sfS,
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 )]}*o O
member countries. The European Commission also participates in the work of the Agency. sC$X7h(Q+
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D t

agreements established within the IEA, and since 1993, its Participants have been conducting a LLMkv!%D
variety of joint projects in the applications of Photovoltaic conversion of solar energy into

electricity. &xV WN>bd^
The Overall programme is headed by an Executive Committee composed of one representative z t1Q_;
from each participating country, while the management of individual research projects (Tasks) w? [)nlNW
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 6\bbP>ql

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ^ a]:GPc
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV r&qD !l5y
systems will continue to represent a significant PV market segment, not only in developing nD_g84us
countries, but also in the important home markets of industrial countries. Experts from 15 IEA [x&&N*>N
countries are sharing their experiences in this area. gyPF!"!5dq
This battery guide is intended for a wide use also close to the end customers to increase the 4D NZ y2`
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle _tjH=Ff$
cost for battery storage in small stand alone photovoltaic systems. Also some basic /xmd]XM=_
environmental concerns are addressed. The report has been prepared under the supervision of 1osI~oNZ
