The international Energy Agency (IEA) founded in November 1974, is an autonomous body ay`R jT
within the framework of the Organisation for Economic Co-operation and Development F7/%,vf
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 Zlt,Us`
member countries. The European Commission also participates in the work of the Agency. z5D*UOy5M
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D meXwmO
agreements established within the IEA, and since 1993, its Participants have been conducting a sPl3JP&s
variety of joint projects in the applications of Photovoltaic conversion of solar energy into >5TXLOYZ
electricity. %Na`\`L{F
The Overall programme is headed by an Executive Committee composed of one representative d/ @P;YN!
from each participating country, while the management of individual research projects (Tasks) %h;1}SFl0
is the responsibility of Operating Agents. Currently nine Tasks have been established in the dDAl n+
IEA PVPS programme. 4Me3{!HJ z

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 9+8N-LZ
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV k!x`cp
systems will continue to represent a significant PV market segment, not only in developing ixoN#'y<"
countries, but also in the important home markets of industrial countries. Experts from 15 IEA et(AO)uv6
countries are sharing their experiences in this area. 'F:Tv[qx
This battery guide is intended for a wide use also close to the end customers to increase the PCa0I^d
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle a]6dhQ`
cost for battery storage in small stand alone photovoltaic systems. Also some basic FBOgaI83G
environmental concerns are addressed. The report has been prepared under the supervision of ^>eV}I5ak
