The international Energy Agency (IEA) founded in November 1974, is an autonomous body ebN(05ZV
within the framework of the Organisation for Economic Co-operation and Development SyK 9Is{8
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 {~bIA!kAFI
member countries. The European Commission also participates in the work of the Agency. y?pD(u
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D #bT8QbJ(
agreements established within the IEA, and since 1993, its Participants have been conducting a =&A!C"qK4[
variety of joint projects in the applications of Photovoltaic conversion of solar energy into #?{qlgv<p
electricity. sM9FE{,mx
The Overall programme is headed by an Executive Committee composed of one representative ;gDMl57PQ.
from each participating country, while the management of individual research projects (Tasks) A8pj~I/*-
is the responsibility of Operating Agents. Currently nine Tasks have been established in the mC i[ Ps
IEA PVPS programme. i:o}!RZ>
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark Al7<s
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), mZ~ qG5@/F

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, HH)"]E5
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV g(aZT#i i=
systems will continue to represent a significant PV market segment, not only in developing [X,A'Q
countries, but also in the important home markets of industrial countries. Experts from 15 IEA QyPg

countries are sharing their experiences in this area. ^P`NMSw
This battery guide is intended for a wide use also close to the end customers to increase the ?Z q_9T 7
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle vUNisVA
cost for battery storage in small stand alone photovoltaic systems. Also some basic A1^Ga5 B>
environmental concerns are addressed. The report has been prepared under the supervision of 'p%= <0vrr
