A common question is: How often will I need to charge my battery?

If using a car battery it depends upon the size and type and state of your battery. Find out how many amphours it is. The energiser draws 0.96 watts (say 1watt). You use the equation: watts = volts x amps (amphours). 1 = 12 x your battery amphours. So if your battery is in top condition and is 25 amphours the answer is 12 x 25 hours = 300 hours which is 12.5 days.

If you want to power it by solar. You are using 1w x 24 hours = 24 watts per day which you need to replace. A 10w panel at an average of 5 hours per day will replace 50w and would seem very adequate. You can always add extra panels if necessary. You will also need a regulator. MGG can supply a 10w panel for $39 and a 144w solar regulator for just $34.90.
