The international Energy Agency (IEA) founded in November 1974, is an autonomous body [+3~wpU(p
within the framework of the Organisation for Economic Co-operation and Development s~b!3l`gu
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 Cj10?BNV)
member countries. The European Commission also participates in the work of the Agency. _08y; _S
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ~&7 *<`7{
agreements established within the IEA, and since 1993, its Participants have been conducting a /I@`B2
variety of joint projects in the applications of Photovoltaic conversion of solar energy into O|e/(s?$
electricity. p9 Y`_g`
The Overall programme is headed by an Executive Committee composed of one representative q6T>y%|FZ
from each participating country, while the management of individual research projects (Tasks) @~j- -L
is the responsibility of Operating Agents. Currently nine Tasks have been established in the (U_ dPf
IEA PVPS programme. _OY<Hb3%M

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, @D2KDV3'
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV p} MH LM
systems will continue to represent a significant PV market segment, not only in developing #(dERET*
countries, but also in the important home markets of industrial countries. Experts from 15 IEA I`KBj6n
countries are sharing their experiences in this area. G&,2>qxK R
This battery guide is intended for a wide use also close to the end customers to increase the `\Hs{t]
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ;_D5]kl`
cost for battery storage in small stand alone photovoltaic systems. Also some basic 12 S[m~L%
environmental concerns are addressed. The report has been prepared under the supervision of e =4k|8 G
