Solar panel help Answered

Hi, i'm buying a small 6v 160mA solar panel for a project I'm working on. I'd like to power a small motor with solar power. How do I "store" some electricity generated by the panel so the motor doesn't stop in short periods of shadow? Thanks, Francisco

Hi Francisco, That is not an easy question, By far the simplest method would be to put a few capacitors across the panel but this would not work due to the amount of current being drawn by your motor (I am guessing around 200mA to 500mA depending on load) The best solution I can think of is to use your solar panel as the supply for a battery charger and use the batteries to power your motor. You should have no trouble finding a suitable schematic of a charger for whatever batteries you may decide to use

Thanks for your answer. You're talking about something like this right? But in this case, I have to open or close the switches my self right? Or if I leave both switches closed, it will work as I want?

So long as the solar panel can supply enough current then you can leave the charger going and the motor going all the time, you are only trying to trickle charge the batteries anyway what you are basically making is an ups that runs on DC - which makes it allot simpler
