Energy recovery from dairy waste-waters: impacts of biofilm support systems on anaerobic CST reactors

A new system for self-controlling of storage batteries being charged by PV plants has been developed. This provides enhanced system reliability, lower system cost. and simpler operation for the user. In this system, the only requirement is to design and select PV panels so That their voltage-sensitive region (on the I V curve) coincides with that required for a simple remote PV plant and for long periods.
