The international Energy Agency (IEA) founded in November 1974, is an autonomous body xQqZi b5I
within the framework of the Organisation for Economic Co-operation and Development hCj8y.X|E(
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 8:
VRq
member countries. The European Commission also participates in the work of the Agency. n." XiXsN
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D }jNVR#D:
agreements established within the IEA, and since 1993, its Participants have been conducting a mDA1$fj"
variety of joint projects in the applications of Photovoltaic conversion of solar energy into t0 T#Xb
electricity. "

The Overall programme is headed by an Executive Committee composed of one representative 2o0WS~}5
from each participating country, while the management of individual research projects (Tasks) P_

is the responsibility of Operating Agents. Currently nine Tasks have been established in the 6N.MC B^
IEA PVPS programme. 2j[; M-3

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Ga;Lm? 6-
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV >i2W YT
systems will continue to represent a significant PV market segment, not only in developing DM{Z#b ]
countries, but also in the important home markets of industrial countries. Experts from 15 IEA (i]0IYMXy*
countries are sharing their experiences in this area. : )k|Onz
This battery guide is intended for a wide use also close to the end customers to increase the Qgl5Jr.
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle _2<d6@}
cost for battery storage in small stand alone photovoltaic systems. Also some basic B)&z% +
environmental concerns are addressed. The report has been prepared under the supervision of tLGNYW!K
