The international Energy Agency (IEA) founded in November 1974, is an autonomous body rJfqA@
within the framework of the Organisation for Economic Co-operation and Development M~
h8Crz
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ,5k-.Md>2*
member countries. The European Commission also participates in the work of the Agency. ?[)S 7\rP
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D {==pZpyyh
agreements established within the IEA, and since 1993, its Participants have been conducting a "E!mva*NU
variety of joint projects in the applications of Photovoltaic conversion of solar energy into Fw4*
electricity. vFmJ;J
The Overall programme is headed by an Executive Committee composed of one representative l0 ] d
from each participating country, while the management of individual research projects (Tasks) MFit|C
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 0(>rG{u
IEA PVPS programme. LX+5|u

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, /)|X.D
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV N Y
systems will continue to represent a significant PV market segment, not only in developing (g8*d^u#PO
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 5rxA<G s
countries are sharing their experiences in this area. 5CYo7mJ 6+
This battery guide is intended for a wide use also close to the end customers to increase the Y#V8(DTyH
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle / l>.mK()
cost for battery storage in small stand alone photovoltaic systems. Also some basic D}mL7d 1
environmental concerns are addressed. The report has been prepared under the supervision of A/*%J7 4v
