The international Energy Agency (IEA) founded in November 1974, is an autonomous body >4&0j'z"
within the framework of the Organisation for Economic Co-operation and Development VQ8Q=!]
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 o&MOcy D
member countries. The European Commission also participates in the work of the Agency. 9@>Q7AUCQ
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ,}/6Za
agreements established within the IEA, and since 1993, its Participants have been conducting a *~k HH
variety of joint projects in the applications of Photovoltaic conversion of solar energy into IG90mpLX
electricity. |3G;Rh9w,
The Overall programme is headed by an Executive Committee composed of one representative p :zRgwcn
from each participating country, while the management of individual research projects (Tasks) &AnWMFo
is the responsibility of Operating Agents. Currently nine Tasks have been established in the r2m&z%N &
IEA PVPS programme. e=`=7 H4P

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, |4rqj 1*U
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV #ri;{d^6
systems will continue to represent a significant PV market segment, not only in developing HcM/
countries, but also in the important home markets of industrial countries. Experts from 15 IEA RT<HiV r`
countries are sharing their experiences in this area. 0i(c XB
This battery guide is intended for a wide use also close to the end customers to increase the yof8L WXx
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle O!P7 W u
cost for battery storage in small stand alone photovoltaic systems. Also some basic z) x.6
environmental concerns are addressed. The report has been prepared under the supervision of n d }Z[)
