member countries. The European Commission also participates in the work of the Agency. C'5i >;
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D $,h*xb.
agreements established within the IEA, and since 1993, its Participants have been conducting a - }

The Overall programme is headed by an Executive Committee composed of one representative H%])>

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ,"}'NH@
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV I{1w8m 4O6
systems will continue to represent a significant PV market segment, not only in developing o'D6lkf0
countries, but also in the important home markets of industrial countries. Experts from 15 IEA $> #PhOC
countries are sharing their experiences in this area. /{qr~7k,oQ
This battery guide is intended for a wide use also close to the end customers to increase the NrL%]dl3/
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle fNB*o={r|
