The international Energy Agency (IEA) founded in November 1974, is an autonomous body PUI.Un2C_
within the framework of the Organisation for Economic Co-operation and Development sM4N`$Is23
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 U+W8)7bc
member countries. The European Commission also participates in the work of the Agency. #ws6z`mt
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D tW(E\#!|p<
agreements established within the IEA, and since 1993, its Participants have been conducting a ;@sxE}`?g
variety of joint projects in the applications of Photovoltaic conversion of solar energy into \]^|IViIQ
electricity. W1 #3+
The Overall programme is headed by an Executive Committee composed of one representative 4VK5TW g
from each participating country, while the management of individual research projects (Tasks) RD~QNj9,T
is the responsibility of Operating Agents. Currently nine Tasks have been established in the A!NT 2YdHZ
IEA PVPS programme. b{(:' .

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, p@P [pzxI
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV Cu >pql<O
systems will continue to represent a significant PV market segment, not only in developing }3@`'i7
countries, but also in the important home markets of industrial countries. Experts from 15 IEA seJc,2Ex
countries are sharing their experiences in this area. z\fk?Tj<ro
This battery guide is intended for a wide use also close to the end customers to increase the E_$ S T 3
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle S6cSeRmw
cost for battery storage in small stand alone photovoltaic systems. Also some basic WS;3a}u
environmental concerns are addressed. The report has been prepared under the supervision of ]SK (cfA`
