I would like to power my blinds with solar panels, although, it can be expensive and complicated as far as circuitry and hardware goes. Charging batteries and maintaining a proper charge requires a charge controller. Batteries themselves can be expensive and unreliable in certain environments. They take longer to charge, are heavy, and dangerous to a certain extent.
I have an idea to make a simple circuit with nothing more than a 5-6v solar panel, a diode, 6v supercap, and the blinds controller. The requirements of the supercaps would be at least 1 amp peak but very low idle. In a 24 hour day each unit will only peak twice for a few seconds. Open and close. The rest of the day it is just idling which is so low, my mobile chargers cant detect the current draw and turn off in a few seconds.
The next steps are to choose the solar panels, supercaps, and a suitable diode. Im sure the cost per unit will be under $10 in parts. Any thoughts or comments are appreciated. So… What do you think? Can it work?
