The international Energy Agency (IEA) founded in November 1974, is an autonomous body CL<m+dW%*
within the framework of the Organisation for Economic Co-operation and Development YQ7tZl;:t
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 Rge \8H/z
member countries. The European Commission also participates in the work of the Agency. 287)\FU;3
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D \* S Ej&9
agreements established within the IEA, and since 1993, its Participants have been conducting a KN"<f :u
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ~?uch8H
electricity.

The Overall programme is headed by an Executive Committee composed of one representative 7r wNjY#
from each participating country, while the management of individual research projects (Tasks) NLF6O9
is the responsibility of Operating Agents. Currently nine Tasks have been established in the Qs;MEt 1
IEA PVPS programme. ]TIBy " 3

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, q ,*([yX
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV o1)8?h
systems will continue to represent a significant PV market segment, not only in developing AIw< 5lW
countries, but also in the important home markets of industrial countries. Experts from 15 IEA y(*#0fJrTV
countries are sharing their experiences in this area. R zN9pAe
This battery guide is intended for a wide use also close to the end customers to increase the B),Z*lpC
