The international Energy Agency (IEA) founded in November 1974, is an autonomous body |bk. gh
within the framework of the Organisation for Economic Co-operation and Development nbj &3z,
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 f]tc$`vb
member countries. The European Commission also participates in the work of the Agency. < S:SIaf0
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D QeuIAs* _
agreements established within the IEA, and since 1993, its Participants have been conducting a ArDkJ`DE
variety of joint projects in the applications of Photovoltaic conversion of solar energy into @/ @#,+
electricity. y

The Overall programme is headed by an Executive Committee composed of one representative 4nmc(CHQ:
from each participating country, while the management of individual research projects (Tasks) [8EzyB>fH
is the responsibility of Operating Agents. Currently nine Tasks have been established in the t7pe)i,)

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, d/vF^v*o0X
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV +Em+W#i%?
systems will continue to represent a significant PV market segment, not only in developing )mT{w9u
countries, but also in the important home markets of industrial countries. Experts from 15 IEA })#6 BN
countries are sharing their experiences in this area. 7%)

This battery guide is intended for a wide use also close to the end customers to increase the J+ r\EN^9
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle MKq:=^ w
cost for battery storage in small stand alone photovoltaic systems. Also some basic p}$VBl$'
environmental concerns are addressed. The report has been prepared under the supervision of ;i\m:8!;
