The international Energy Agency (IEA) founded in November 1974, is an autonomous body nef-xxXC^I
within the framework of the Organisation for Economic Co-operation and Development <}B|4($
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 u%v^(9z
member countries. The European Commission also participates in the work of the Agency. v }P~g
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D qY#*zx
agreements established within the IEA, and since 1993, its Participants have been conducting a ;
Sh |6
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 6o6!O l
electricity. :GGsQ

The Overall programme is headed by an Executive Committee composed of one representative &t p5y}=n
from each participating country, while the management of individual research projects (Tasks) 5p"*n kF
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ,3N8
IEA PVPS programme. | %6B#uy

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, n>Zkx+jLj<
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV zA-?x1th&
systems will continue to represent a significant PV market segment, not only in developing f\ /} ;a
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ilFM+x @
countries are sharing their experiences in this area. APK@Oq
This battery guide is intended for a wide use also close to the end customers to increase the mb\vHu*53
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle I|iI

cost for battery storage in small stand alone photovoltaic systems. Also some basic :gQc@)jZ(*
environmental concerns are addressed. The report has been prepared under the supervision of +wT,dUin_<
