Hello,
first of all, i want to say i am a big noob in eletronics, i learn my best in the internet and try to apply it in real world, i have had nasty experience of going into pratical without knowing the theory first in eletronics, and i paid the price burning my hand. So i quite want to have the theory first before even thinking to do anything.
ok, so, i have a 80 watt solar panel, and i want to drive 2 eletric DC Linear actuators, to move a heavy thing. details on this is not necessary as for i need help is in the capacitors.
so each motor is as estimated a low RPM DC motor with high torque, which these ones give out around 1200N of force in the mechanical geared actuator. these two motors consume 3 amps, at a voltage of 12V. multiplying it gives 36W each, so both would consume 72 watts when operating at the same time. Besides this, i also have an arduino, a 4 channel relay, and a few LDRs and switches. and a 4A thermoeletric Peltier module, with a heat sensor, and other sensors too, i have an arduino Uno, i am thinking in getting a multiplexer for the analog inputs but it seems very complicated, i think i will aquire a Arduino Mega. (Sainsmart has a cheap and very good one).
for the record, i am studying renewable energies.
and by far when you grabbed your mental calculator, you pretty much see the solar panel i have wont suffice for my needs right?
yep, that's when the Capacitor banks i read so much about, and saw so many videos about, even a rail gun.
so, i know so far that the capacitors have a very different use from a battery, like for one of those dozens of videos i saw, i can actually turn a small AC current into a DC current using just capacitors and a few diodes.
so, the idea of replacing a large battery here, is to prevent a deep charge or use of expensive controllers to take care of the batteries, and also the actuators wont be constantly running. they are for positioning accurately, so i dont need to run them constantly. only a few times per hour. making the calculations, without the two motors running at the same time it will give me around 55 to 65 watts of usage. and i forgot, i will use 2 small Dc water pumps, like those in aquariums. so i have then 15 watts of energy left for use. what i have now is a car baterry and its not fullfiling my needs.
so this is my idea:
to have a capacitor bank, that can power 72 watts of both motors for around 10 minutes. and be recharged fast with the 15 watts i have left to use from power from the solar panel, and then, capable of powering a single arduino in sleep mode, for 36 hours.
i heard avout the super capacitors and ultra capacitors, i went to check some prices, and well... my budget is not that big. so as cheap as possible is what i'm aiming at. Also capacitor bank volumes is not a problem. not weight.
can you please help me out in a capacitor bank that suits my needs?
How many Farads i would need? in parallel? or in series?
and thank you so much for taking your precious time to read this. i really apreciate it alot. and if help me, even more!
i'm just another DIY-er with super enthusiasm both in renewable energies and eletronics, although picked eletronics road,
as my family used to say, " a road is just one lane, a highway has more lanes". pretty inspiring to me to get into the multitasking world too. will you help me slowly getting into the eletronics world with this?
