The international Energy Agency (IEA) founded in November 1974, is an autonomous body RN&8dsreZp
within the framework of the Organisation for Economic Co-operation and Development f*m^x7
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 5yW}#W>
member countries. The European Commission also participates in the work of the Agency. E3x<o<v
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D c*(= Glzn
agreements established within the IEA, and since 1993, its Participants have been conducting a *Hv d
variety of joint projects in the applications of Photovoltaic conversion of solar energy into A-^B ?E
electricity. uc=u4@.>
The Overall programme is headed by an Executive Committee composed of one representative z,!A4ws
from each participating country, while the management of individual research projects (Tasks) ePSD#kY5
is the responsibility of Operating Agents. Currently nine Tasks have been established in the hA`9 [58/
IEA PVPS programme. ZY6%%7?1

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 7 lq$Ps C
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV bDegIW/'w
systems will continue to represent a significant PV market segment, not only in developing p@?(m/m$
countries, but also in the important home markets of industrial countries. Experts from 15 IEA @ L/i
countries are sharing their experiences in this area. rd X;
This battery guide is intended for a wide use also close to the end customers to increase the :19s=0
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle kWbY&]ZO
cost for battery storage in small stand alone photovoltaic systems. Also some basic E*v+@rv
environmental concerns are addressed. The report has been prepared under the supervision of # S|On[Q !
