The international Energy Agency (IEA) founded in November 1974, is an autonomous body *G;D u `;
within the framework of the Organisation for Economic Co-operation and Development \t]aBT,
(OECD) which carries out a comprehensive programme of energy co-operation among its 23
pqxBu
member countries. The European Commission also participates in the work of the Agency. 5fud:k
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D +ZeK,Y+Xy
agreements established within the IEA, and since 1993, its Participants have been conducting a {m 5R=22^
variety of joint projects in the applications of Photovoltaic conversion of solar energy into b ;t b&o
electricity. ?1lx8+
The Overall programme is headed by an Executive Committee composed of one representative M@O<b-
from each participating country, while the management of individual research projects (Tasks) '2c4

is the responsibility of Operating Agents. Currently nine Tasks have been established in the ]e]hA@4
IEA PVPS programme. 5b%zp x0Y

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, LQ=Fck~[r
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV & ?B\(? *
systems will continue to represent a significant PV market segment, not only in developing Ov8{ny
countries, but also in the important home markets of industrial countries. Experts from 15 IEA QzA/HP a
countries are sharing their experiences in this area. h*? /[XY
This battery guide is intended for a wide use also close to the end customers to increase the 4p_@f^v~QH
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle [[d@P%X&
cost for battery storage in small stand alone photovoltaic systems. Also some basic E 9n7P'8
environmental concerns are addressed. The report has been prepared under the supervision of &1,qC,:!
