Details: 
I am charging (2) 12vdc batteries in parallel from my 1.5w solar panels wired in parallel that I have measured with a max output of 36vdc. I built an icechest stereo that I want the solar panels to maintain a charge on as we are floating down the river. I currently have a voltage regulator in now but it limits the output to 10vdc, not really good enough to maintain an appropriate charge on the batteries. Can you help me out?
Thanks

Answers

A: 
As per your querry i think you are looking for Step-down constant voltage regulator whose input is 36V (sourcing from solar panel) and output of 12V (to charge a 12V battery).

The recommended solution for this is you can use a DC-DC module from Murata with part No:7812SRH-C newark code is 87K6149 or
check the part from TI #PT6886A and its newark code is 75C6943
