The international Energy Agency (IEA) founded in November 1974, is an autonomous body e> -fI_+b
within the framework of the Organisation for Economic Co-operation and Development Q .Xs%{B
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 w9]H J3qi
member countries. The European Commission also participates in the work of the Agency. qbD>)} :1
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D )]M,OMYq -
agreements established within the IEA, and since 1993, its Participants have been conducting a x,: DL)$1
variety of joint projects in the applications of Photovoltaic conversion of solar energy into YgL{*XYAt
electricity. o4F( X0
The Overall programme is headed by an Executive Committee composed of one representative #Q'j^y 7=z
from each participating country, while the management of individual research projects (Tasks) 9mRP%c#(
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ~

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, !j%MN{ #a
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV =}UcYC6l
systems will continue to represent a significant PV market segment, not only in developing (j?ckah%V
countries, but also in the important home markets of industrial countries. Experts from 15 IEA MmQ"z_v
countries are sharing their experiences in this area. []b=

This battery guide is intended for a wide use also close to the end customers to increase the =M`Xu#eRk
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle #sM`>KG6T1
cost for battery storage in small stand alone photovoltaic systems. Also some basic '@dk3:3t
environmental concerns are addressed. The report has been prepared under the supervision of 9oQ$w?=#$
