I'm using an attiny microprocessor that uses around 6mA plus another 3mA for the LED. It periodically runs a servo ( Tower 9G ) that according to a few source online draws 120 - 200 mA ( for around 6 seconds ). (200 x 6)/3600 gives me .33 mAh. If I add the two together, I get a draw of 10 mAh a day. Now lets say i had a tiny battery, something like this one. that has 100 mAh. If i then add a solar panel like this that is capable of providing 45 mA in peak sun, It sould ba able to provide more than ample power to keep the battery fully charged indefinely ... are my calculations correct? or am I missing something?
