The international Energy Agency (IEA) founded in November 1974, is an autonomous body G>c:+`KS
within the framework of the Organisation for Economic Co-operation and Development +`~6Weay
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 yixAG^<
member countries. The European Commission also participates in the work of the Agency. Q"sszz
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D xsdi\
j;n>
agreements established within the IEA, and since 1993, its Participants have been conducting a \#)w$ O
variety of joint projects in the applications of Photovoltaic conversion of solar energy into A"~4|`W
electricity. G^/8lIj
The Overall programme is headed by an Executive Committee composed of one representative dgM@|&9*m
from each participating country, while the management of individual research projects (Tasks) 'z3I*[!
is the responsibility of Operating Agents. Currently nine Tasks have been established in the X=i",5;
IEA PVPS programme. E?[] N[0Kl

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, &S+o oj
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV rc +} KO
systems will continue to represent a significant PV market segment, not only in developing wW+@3bPl
countries, but also in the important home markets of industrial countries. Experts from 15 IEA &)v }oHy,m
countries are sharing their experiences in this area. & a

This battery guide is intended for a wide use also close to the end customers to increase the sW]fPa(cn,
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle Tg ~SGAc
cost for battery storage in small stand alone photovoltaic systems. Also some basic RYuR&0_{
environmental concerns are addressed. The report has been prepared under the supervision of |QB[f*y5
