The international Energy Agency (IEA) founded in November 1974, is an autonomous body DI)"F OM6
within the framework of the Organisation for Economic Co-operation and Development UG44 oKB
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 : F3UJ[V
member countries. The European Commission also participates in the work of the Agency. Z42q}Fhm*R
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D i-w<5pGnf
agreements established within the IEA, and since 1993, its Participants have been conducting a ]2L11" erP
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 0Gj/yra9MO
electricity. ,eTdQI;
The Overall programme is headed by an Executive Committee composed of one representative `yq)

from each participating country, while the management of individual research projects (Tasks) @[joM*U
is the responsibility of Operating Agents. Currently nine Tasks have been established in the FS8l}t
IEA PVPS programme. gna!Q

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Q0`@=5?-
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV Ho}*Bn~ic
systems will continue to represent a significant PV market segment, not only in developing GR (m+%Vw!
countries, but also in the important home markets of industrial countries. Experts from 15 IEA %o/@0.w
countries are sharing their experiences in this area. #k<l 5x`
This battery guide is intended for a wide use also close to the end customers to increase the Q(x= ;wf5r
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle RF8, qz
