Re: two axis solar tracking system

hey guys its me again. can you tell me if the calculations bellow are right? my battery is 5Ah. which also means a 1A current will charge it in 5 hours. Now since my solar panel is 0.58A, the battery will take about 9.5hours to fully charge provided the solar panel outputs 0.58 for the whole 9 hours...

Re: two axis solar tracking system

Hi everyone, one more question... in my prototype, im using a 10W solar panel which weighs 1.5kg. how can i select the best stepper motor which would drive this without any problem? lets say the pivot is at the middle of the solar panel (dimensions: 36 x 31cm). my solar panel is charging a battery (...

but the problem is with the actual sensing element. i want the position converted in to electrical signals. how to do this? if i use LDRs or photo transistors, to get a good accuracy or precision, i will have to fix lots of them, hence lots of wires. How many is "lots"? I count four for analog or t...

hi yea im looking for an optical type of sensor. also im planing to use a microprocessor to run the algorithm to calculate the path, but only as a backup plan to the actual sensor. i.e. if it is too cloudy and sensor readings get unreliable, i might use the algorithm to calculate the path. (why dont...

two axis solar tracking system

hi all, i intend working on a prototype for a two axis solar tracking system. i purchased a small 10W, 12V, 1.58A, 1.5kg solar panel with dimensions: 31x36cm. All i want to do is move this in two axis to track the sun (both day and seasons) now my main problem is, how to build a simple sensor system...
