The international Energy Agency (IEA) founded in November 1974, is an autonomous body 88x_}M^Fnl
within the framework of the Organisation for Economic Co-operation and Development i#]}k
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 j>Wb$p6S
member countries. The European Commission also participates in the work of the Agency. k=!lPIx
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D F F X-k S
agreements established within the IEA, and since 1993, its Participants have been conducting a `,a6su (?
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 1=:=zyEEo
electricity. + 2 v6fan
The Overall programme is headed by an Executive Committee composed of one representative ;]!QLO.bs^
from each participating country, while the management of individual research projects (Tasks) {2 l35K=
is the responsibility of Operating Agents. Currently nine Tasks have been established in the F |pM$Kd`
IEA PVPS programme. UgI0

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, " E+V >V+
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 5" 5!\Zo
systems will continue to represent a significant PV market segment, not only in developing San3^uX
countries, but also in the important home markets of industrial countries. Experts from 15 IEA *g7BR`Bt]z
countries are sharing their experiences in this area. E$l 4v>iA
This battery guide is intended for a wide use also close to the end customers to increase the 9#(Nd, m})
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle JC6?*R
cost for battery storage in small stand alone photovoltaic systems. Also some basic mD@*vq
environmental concerns are addressed. The report has been prepared under the supervision of xb{G:v
