The international Energy Agency (IEA) founded in November 1974, is an autonomous body 9<Bf5d
within the framework of the Organisation for Economic Co-operation and Development O,bj_CW x
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 /yI~( 8bO
member countries. The European Commission also participates in the work of the Agency. *</;:?
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D W=|B3}C?
agreements established within the IEA, and since 1993, its Participants have been conducting a |mK d5[$
variety of joint projects in the applications of Photovoltaic conversion of solar energy into RuH Jk\T+
electricity. 8n'C@#{WV
The Overall programme is headed by an Executive Committee composed of one representative vI+ PL(T@
from each participating country, while the management of individual research projects (Tasks) 7?A}q mv
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ./6L&?*`~;
IEA PVPS programme. / '7WL[<

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, bg$e80
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV & XrV[d[>
systems will continue to represent a significant PV market segment, not only in developing Bz24U wcZ
countries, but also in the important home markets of industrial countries. Experts from 15 IEA =GLsoc-b
countries are sharing their experiences in this area. c\R! z&y~
This battery guide is intended for a wide use also close to the end customers to increase the i r\
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle EJ86k>]
cost for battery storage in small stand alone photovoltaic systems. Also some basic 3w0m:~KS6V
environmental concerns are addressed. The report has been prepared under the supervision of Dm 5UQe
