Task III of the PVPS programme, active since 1993, focuses on the exchange of information, WTW ONO>
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV Bgw =((p
systems will continue to represent a significant PV market segment, not only in developing `p qj~s
countries, but also in the important home markets of industrial countries. Experts from 15 IEA rf@ Cz%xDD
countries are sharing their experiences in this area. F_ C7S
This battery guide is intended for a wide use also close to the end customers to increase the $wnK"k%G
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle e3T&KyPm?+
cost for battery storage in small stand alone photovoltaic systems. Also some basic 7I\qE r57
environmental concerns are addressed. The report has been prepared under the supervision of s0EF{2<F
