hi.
well i have to implement an intelligent lighting system. after
detecting the person from PIR sensors, light has to be switched on for
some time only at night time. Im using a 12 V battery as a power
source which is powered by solar pannel.
im having the problem in keeping the battery output constantly at 12
V, because after sometime the voltage is bound to drop, and the
circuitry will not work properly in fluctuating voltage.


You need more batteries!

Also, Google for 'sepic'.

Bob Monsen
