The international Energy Agency (IEA) founded in November 1974, is an autonomous body T,;6q!s=
within the framework of the Organisation for Economic Co-operation and Development |vGz
1jLV
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ne;,TJ\
member countries. The European Commission also participates in the work of the Agency. b7=]"|c$@
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ]
Li(E:
agreements established within the IEA, and since 1993, its Participants have been conducting a [t0gX dU 6
variety of joint projects in the applications of Photovoltaic conversion of solar energy into (}}BZ S& .
electricity. Z EG
The Overall programme is headed by an Executive Committee composed of one representative fa$ Fo(.
from each participating country, while the management of individual research projects (Tasks) FzW(An&x2
is the responsibility of Operating Agents. Currently nine Tasks have been established in the z<)?8 tAgq
IEA PVPS programme. 5<&<61[A

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, _< xU"8b"5
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV =7 Nm= 5@
systems will continue to represent a significant PV market segment, not only in developing 2<<,aL*
countries, but also in the important home markets of industrial countries. Experts from 15 IEA R$v{ p[
countries are sharing their experiences in this area. ZJd 1Lx
This battery guide is intended for a wide use also close to the end customers to increase the _e/v w:
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle uGgR@+7?Z
cost for battery storage in small stand alone photovoltaic systems. Also some basic j# o0y5S
environmental concerns are addressed. The report has been prepared under the supervision of I2D<~xP~2+
