solar battery amp hours and panel which one ?
The parameters are: The 'show' will take place every hour for eight hours during daylight hours.. Each hour every 10 mins the system will switch ON and power will be needed to operate 25 automatic car antennas that draw about 0.8amps for about 1 minute show time. So every hour I will be drawing 25*0.8*6 = 120 ? -- I am new to this so i figure my calculations are wrong as 120amps seems a lot --
the system will also be powering an Arduino board which will be controlling the overall timing and puppetering of the work ie some coil relays or transistors for lower power consumption.
this project will be installed in Germany in the summer with average sunlight conditions .. From my reading up on the subject I understand that it is not good to drain a battery, ideally half drain is max...could someone please advise what values i need for battery and solar panel.. thanks in advance ..
