Solar tracker

Projects Programming
1

Hey, I am designing a solor tracker usinf 4 LDR senors. Purpose of this project is to develop 2 codes one with senors and other without senors and then comapre which system will be more efficient on a sunny day.

I have managed to get a code for system with 4 LDR senors, but I have no idea what to do with the second part. I am new with Arduino so very sorry if it is looks very simple but for me it is "mission impossible".

Would you please someone could help me developing a code? The Idea is that the tracker should use let say 15 degress solar panel every hour. Would be great if controler would go to sleep when it is not being used. I have added a picture of my tracker bellow. I need to get it done by next week so if someone knows how to do it I would be more than happy to pay for it or idealy expalin me how to do it.

If you want someone to write code for you this is not the place to ask.

your approch with 4 ldr is not correct. For example, In case of partial sunny you get different variations (left-right)(up-down).

what means "system without sensors"? With what?

The time (1 week) is certainly not enough

For hired help, post on the Gigs and Collaborations forum section.

It is no problem to move the panel 15 degrees per hour, given that you already have a motorized platform.

Sun moves 15 degress every hour that's what I need to define in my code. Let say solar panel is faced at 90 degrees so after an hour it should be faced at 75 and so on. Yeah I know one week is not enough but that is all I have. It does it need to be perfect since I am studying Eletrical stuff with high voltages involed. I would happy if I could do it by myself but I do not know how.

Hi

for the second part for your project take a look at this:
http://www.cerebralmeltdown.com/open-sun-harvesting-project

the idea is simple you can build it on your own
first you have to find the equations of sun azimuth and zenith angles

and to make the solar panel perpendicular to the sun: build equations and algorithms to transform the sun angles (from the first equation) for every day and every second (or every minute as you require) of the day to the stepper motors rotation degrees

Hi, is this a school, college, uni project?

Sounds very close to the project I am writing code for on my group project. Except we don't need to write for no sensors.

I would start with The Solar Position Library & An Equatorial mount

Except we don't need to write for no sensors.

Does that mean you will be writing code for "some" sensors?

Hi,
google solar tracking without sensors
