A compilation of the hybrid systems greater than 4 kW is given in the Appendix 1, Table of
Hybrid Systems. Laboratory test projects were not included. The table lists site name,
location, sizes/manufacturer of components, and the current status of the system. Hybrid
systems have a 65% or more failure rate, with failures due to components failing, poor
maintenance, and inadequate support by systems suppliers after installation. Institutional
issues related to lack of proper maintenance usually prove key in the death of most any
village hybrid system (i.e., systems have often been installed and then walked away from
and expected to survive on their own).
