Foreword 2Q-kD?PO,
The international Energy Agency (IEA) founded in November 1974, is an autonomous body \/S?.P#L~
within the framework of the Organisation for Economic Co-operation and Development 6(<M.U_ft
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 *.ZV .(
member countries. The European Commission also participates in the work of the Agency. X];a(7+2
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D d+ql@e ]
agreements established within the IEA, and since 1993, its Participants have been conducting a ){L`hQ*=w
variety of joint projects in the applications of Photovoltaic conversion of solar energy into oC^-" (#
electricity. ,hYUxh45
The Overall programme is headed by an Executive Committee composed of one representative /8 Ca8Ju
from each participating country, while the management of individual research projects (Tasks) !

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ~~&8I!r e
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV haqL

systems will continue to represent a significant PV market segment, not only in developing \b{=&B[Q$'
countries, but also in the important home markets of industrial countries. Experts from 15 IEA Rb'," ` 7
countries are sharing their experiences in this area. }#a d
This battery guide is intended for a wide use also close to the end customers to increase the zl4Iq+5~6Q
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle Ub4j 3`
cost for battery storage in small stand alone photovoltaic systems. Also some basic !pQQkZol
environmental concerns are addressed. The report has been prepared under the supervision of Q <w rO
