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...

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 (...

Dear Solar Pulse However over the years I have collected a few articles that detail building such devices. Let me know if you are interested and I will gladly send you this information. Pius yep that would be of great help to me. ud be able to directly email me them from here. well guys, thanx agai...

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 a...

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...

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...
