The international Energy Agency (IEA) founded in November 1974, is an autonomous body s/^= WV
within the framework of the Organisation for Economic Co-operation and Development } 4`YdN
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 / ^M3-5@Q
member countries. The European Commission also participates in the work of the Agency. Ec/+ 9H6g
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D .%h_W\M<l
agreements established within the IEA, and since 1993, its Participants have been conducting a #^w 1!xXD
variety of joint projects in the applications of Photovoltaic conversion of solar energy into }(O

electricity. 93 b5S>&r
The Overall programme is headed by an Executive Committee composed of one representative m{Xf_rQ

from each participating country, while the management of individual research projects (Tasks) S?WUSx*N
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 1@@]h!>k:

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, L7="! I
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV n8C {Okr
systems will continue to represent a significant PV market segment, not only in developing \05C'z3]
countries, but also in the important home markets of industrial countries. Experts from 15 IEA aa3Y tNpP
countries are sharing their experiences in this area. 3p#^#1/_
This battery guide is intended for a wide use also close to the end customers to increase the iKO~#9OF
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ,FPgs0rrS
cost for battery storage in small stand alone photovoltaic systems. Also some basic $>`8'I
environmental concerns are addressed. The report has been prepared under the supervision of +eat ,3Ji
