The international Energy Agency (IEA) founded in November 1974, is an autonomous body <?va)
ou
within the framework of the Organisation for Economic Co-operation and Development (j 8,n<o
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 @IKe<{w
member countries. The European Commission also participates in the work of the Agency. Cot\i\]jv
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ,8 NEnB
agreements established within the IEA, and since 1993, its Participants have been conducting a Q1&dB{L
variety of joint projects in the applications of Photovoltaic conversion of solar energy into O? J:+L(
electricity. MldL" *HW:
The Overall programme is headed by an Executive Committee composed of one representative 5 9J $SE
from each participating country, while the management of individual research projects (Tasks) qO3BQ]UF
is the responsibility of Operating Agents. Currently nine Tasks have been established in the %IX W|mi

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, u iEA=*axp
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV /<(ik&%N
systems will continue to represent a significant PV market segment, not only in developing g*imswj7
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 2 3 w{h d
countries are sharing their experiences in this area. O ;t?@!_
This battery guide is intended for a wide use also close to the end customers to increase the iC2nHZ*,
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle Hu 2g (!
cost for battery storage in small stand alone photovoltaic systems. Also some basic E }j8p_p
environmental concerns are addressed. The report has been prepared under the supervision of ;@s~t:u
