The international Energy Agency (IEA) founded in November 1974, is an autonomous body s4 Vju/
within the framework of the Organisation for Economic Co-operation and Development !sYZ1;WAO
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 </R @)_'
member countries. The European Commission also participates in the work of the Agency. b fkFk
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D -OnKvpeI
agreements established within the IEA, and since 1993, its Participants have been conducting a fA=Lb^,M
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ID,os_ T=
electricity. Dj 6^|R$z&
The Overall programme is headed by an Executive Committee composed of one representative _qh \
from each participating country, while the management of individual research projects (Tasks) =5uhIU0O
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 12Fnv/[n'K
IEA PVPS programme. k L4 #

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Ak$9\Sl
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV xn)F(P 0kv
systems will continue to represent a significant PV market segment, not only in developing +?{LLD*2e
countries, but also in the important home markets of industrial countries. Experts from 15 IEA =\\rk,F
countries are sharing their experiences in this area. Bx.hFEL
This battery guide is intended for a wide use also close to the end customers to increase the =5:kV /p
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 17w{hK4o8O
cost for battery storage in small stand alone photovoltaic systems. Also some basic 1f?F uw
environmental concerns are addressed. The report has been prepared under the supervision of U.ZA% De
