Foreword <?.&^|kS
The international Energy Agency (IEA) founded in November 1974, is an autonomous body # $07:UJ
within the framework of the Organisation for Economic Co-operation and Development a(X@Q8l:
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ',@3 >T**
member countries. The European Commission also participates in the work of the Agency. ^98~U\ar
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D >Eto(
y"q
agreements established within the IEA, and since 1993, its Participants have been conducting a kd(8I_i@
variety of joint projects in the applications of Photovoltaic conversion of solar energy into O Rw,)l
electricity. DU'`ewLL7
The Overall programme is headed by an Executive Committee composed of one representative Af2( 5]
from each participating country, while the management of individual research projects (Tasks) :J@ gmY:C
is the responsibility of Operating Agents. Currently nine Tasks have been established in the R4cM%l_#W
IEA PVPS programme. c

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, }@+0/W?\.
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV :U%W%
systems will continue to represent a significant PV market segment, not only in developing "Ac-tzhE
countries, but also in the important home markets of industrial countries. Experts from 15 IEA P
l]O\vh
countries are sharing their experiences in this area. ^"2J]&x`G
This battery guide is intended for a wide use also close to the end customers to increase the E6ElNgL
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle mR:uj2*
cost for battery storage in small stand alone photovoltaic systems. Also some basic D=Gtq6jd
environmental concerns are addressed. The report has been prepared under the supervision of WX?IYQ +
