solar panel recharge question

[Vince]

Hi,

I have a solar panel which generates a max of 2W out.

Would it be possible to trickle chargle batteries of a higher voltage?

I have a high voltage battery (12VDC...ok not that high) running many
smaller low voltage LED's. As the LED's dont use much energy, Im assuming
that a small solar panel can put back what the LED's took out.

If this is possible, do I need any extra's to hook it up besides a diode?

If the output voltage of the solar panel exceeds the battery voltage, then
the solar panel will charge the battery. Otherwise, you will need a dc
inverter to boost the solar panel voltage.
