I bought a solar panel, with a 50W regulator. The question is that I
recently bought a second solar panel, and want to connect the two
solar panels at the same time to get more energy and better capacity.
The question is how can I get (or build up) a regulator with the new
I'll thank a lot the help you can give.
Thanks in advance,
If the output of the two regulators is DC then you could diode-or the two
regulators, like this:
Be sure to get diodes with enough ampacity, also Schottky diodes have a low
forward voltage drop, making them very efficient for this.
Make sure to watch the total power dissipation in the diodes, you will need
a lot of assumptions would have to be made to provide a response here.
is it a voltage regulator, current regulator or both? make / model? specs
of solar panel?
type of load?
could be that the existing unit will work fine for you if you have not
increased your load.
What is the wattage of the solar panels, and what is the load/
application? If you are using the solar panels to charge a battery,
usually you can just hook both regulators, with one solar panel per
regulator, to the battery without problems and they will self-regulate
the current delivered to the battery. If the solar panels are small
enough that your single regulator can handle both of them at once,
then you can use the diode-or method described by ccr500r to connect
them both to the regulator. Be warned that you will lose a significant
amount of the power from your solar panels in the diodes, and you
definitely need to make sure the diodes are large enough and well heat-
I'm not quite sure whose regulator you are using, so the above advice
may not be applicable to your specific system. Generally, with smaller
systems like this using low cost ( Thanks in advance,
