The international Energy Agency (IEA) founded in November 1974, is an autonomous body v5RS <?o
within the framework of the Organisation for Economic Co-operation and Development 45>w=O
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 -|:7<$2#I
member countries. The European Commission also participates in the work of the Agency. M

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D w' #VN|;;!
agreements established within the IEA, and since 1993, its Participants have been conducting a Y6W3WPs(
variety of joint projects in the applications of Photovoltaic conversion of solar energy into Fu(e4E
electricity. 6P3ezl@#;
The Overall programme is headed by an Executive Committee composed of one representative `3*>tq
from each participating country, while the management of individual research projects (Tasks) &W)ks
is the responsibility of Operating Agents. Currently nine Tasks have been established in the !f V.#9AB#
IEA PVPS programme. )|q,RAn

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, [="moh2*f
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV $Vlfg51 ob
systems will continue to represent a significant PV market segment, not only in developing 1W"9u
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ak;fCx&
countries are sharing their experiences in this area. 0@.$(Aqo(
This battery guide is intended for a wide use also close to the end customers to increase the Xa Yx avq
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle tQF7{F-}
cost for battery storage in small stand alone photovoltaic systems. Also some basic NGd|7S[^+c
environmental concerns are addressed. The report has been prepared under the supervision of /1gKc}rB2
