The international Energy Agency (IEA) founded in November 1974, is an autonomous body N]sX
r
within the framework of the Organisation for Economic Co-operation and Development q}["Nww-
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 $' Hg}|53
member countries. The European Commission also participates in the work of the Agency. qqYH}%0dz
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D lFY;O !Y5\
agreements established within the IEA, and since 1993, its Participants have been conducting a P!";$]+
variety of joint projects in the applications of Photovoltaic conversion of solar energy into uv[e0, @
electricity. : Y [r^=>
The Overall programme is headed by an Executive Committee composed of one representative VmB/X))
from each participating country, while the management of individual research projects (Tasks) +6{KrREX)
is the responsibility of Operating Agents. Currently nine Tasks have been established in the R%Yws2Le2
IEA PVPS programme. K9*#H(

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, U9xFQ=$ 2
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ";e0-t6:
systems will continue to represent a significant PV market segment, not only in developing 6P;1I+5m{q
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ?^&!/,
countries are sharing their experiences in this area. &w3LM OT
This battery guide is intended for a wide use also close to the end customers to increase the P"u* bqk
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle JCZJ\f*EZ
cost for battery storage in small stand alone photovoltaic systems. Also some basic p$@=N6)I.k
environmental concerns are addressed. The report has been prepared under the supervision of 6#5@d^a
