The international Energy Agency (IEA) founded in November 1974, is an autonomous body #4JMb#q0E
within the framework of the Organisation for Economic Co-operation and Development AH#mL
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 P |t yyjO
member countries. The European Commission also participates in the work of the Agency. u%~'+=
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D A?H#bRAs
agreements established within the IEA, and since 1993, its Participants have been conducting a TQ]gvi |m
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ENuL!H>;*
electricity. "[N2qJ}p
The Overall programme is headed by an Executive Committee composed of one representative ENZym
from each participating country, while the management of individual research projects (Tasks) ryL1 <u

is the responsibility of Operating Agents. Currently nine Tasks have been established in the ~HB#7+b
IEA PVPS programme. E`o_R=%

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 0vqVE]C
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV SZF 8InyF
systems will continue to represent a significant PV market segment, not only in developing :1A:g^n
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 1
pVw,}
countries are sharing their experiences in this area. !|Q&4NS
This battery guide is intended for a wide use also close to the end customers to increase the :}e<
