The international Energy Agency (IEA) founded in November 1974, is an autonomous body j+{cc: h"X
within the framework of the Organisation for Economic Co-operation and Development MNb9 ~kM
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 CDsl)
member countries. The European Commission also participates in the work of the Agency. T?6<1nU)
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D e6

agreements established within the IEA, and since 1993, its Participants have been conducting a +v:] #1
variety of joint projects in the applications of Photovoltaic conversion of solar energy into >VQLC&u (
electricity. DT)] [V^w
The Overall programme is headed by an Executive Committee composed of one representative k;2.g$)W[c
from each participating country, while the management of individual research projects (Tasks) <>Dw8?O
is the responsibility of Operating Agents. Currently nine Tasks have been established in the YRr,{[e
IEA PVPS programme. $xq04ejJ

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, V2M4g
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV m%>}T 75C^
systems will continue to represent a significant PV market segment, not only in developing O8_! !Qd
countries, but also in the important home markets of industrial countries. Experts from 15 IEA qSG0TWD!pq
countries are sharing their experiences in this area. }4H}*P> +
This battery guide is intended for a wide use also close to the end customers to increase the "#-iD
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle )*{B_[
cost for battery storage in small stand alone photovoltaic systems. Also some basic +`>E_+Mp
environmental concerns are addressed. The report has been prepared under the supervision of xpo^\E?2
