Guess we've all heard Solar tracker, a vital device in solar system, i don't know if it's already been
mentioned in one of the numerous pages;
Haven't heard of a company nor individual installing it.
I bet it's a nice investment to make considering the fact it can recover from 40%-60% of the energy from the sun.
To practically test this assertion, I've tried measuring the amps on an 80w solar panel that i pointed directly to the sun. I got around 6.8A.
When pointed at 30 degrees away from the sun I got around 3.5A.
But at 45 degrees to the sun the meter reads 1.8A.
Suffice to say this experiment was done around 2.00pm with the sun clearly visible and no obstructing clouds.
You might try that on your own and you would be amazed at the energy that is being wasted using fixed solar panel.
I want to commence building these solar trackers at affordable prices and selling them here in Nigeria. I have already ordered all the parts I would be needing to build it from Aliexpress and Ebay.

I also have some new batteries and Mppt charge controllers that I am offering for sale. They were the remains of a project I did for a client of mine. They were supposed to be used for a solar project but were set aside when some couple dozens of 12v 600ah American specs batteries arrived the scene .
The specs of the batteries are as follows;
Model: Storace SRG100-12 valve regulated gel cell.
Voltage: 12v
Capacity: 100ah
The batteries goes for N17,000 per piece..
The specs of the Mppt charge controller are as follows;
Input voltage: 12v-100v
Output voltage: 12v/24v
Output power: 120w(12v), 240w(24v)
The Mppt charge controllers goes for N8,000 per piece..
Below are the pictures of the batteries and Mppt charge controller...

high cost of procurement has always been the disadvantage of trackers. You may however oversize ur array a little bit to compensate for losese due to angle of inclination. Your controller must be very smart at performing HVD.

also, I am sure the mechanical parts of the trackers will fail after few years of use.( refer to ur motorised dish).
Re: Solar Energy, A Complement To FTA by adrusa: 10:35pm On Jul 14, 2015
Trackers also become difficult to implement when the array becomes large.

Its amazing how people apply theory with out practical.
We all know that a 16mm cable can take up to a 100A if its pure copper.
Please I don't think you should say more as you promised.

Every one is learning. rather than chastise teach. They come to this forum seeking knowledge or correction of long held notions. The American wire chart is correct if you use awg as your size which some people do.
Brothers and sisters don't be afraid to ask for clarification. I prefer to be called stupid than be quiet and smart and burn my house down. We all can contribute to improving our community and society.

It really amazes me how people respond here as if they have monopoly of knowledge, the last time I checked, this is a DIY thread and I bet the most professional and the least professional here picks something from each other.

Let us try to contribute responsibly and also help each other as much as we can and as well respect each others' opinion and contributions.

Yes the high cost of procurement has always been the
disadvantage of trackers, that is because we buy from the oversees.
That i intend to tackle. I am making arrangements on a platform that will enable an individual to acquire a solar tracker that can accommodate a total capacity of 600w solar panel arrays at roughly N12,000 or lower along with 1year guarantee.
Oversizing your array a little bit to compensate for
losese due to angle of inclination would waste more money than it would if you had acquired a solar tracker, and in such case you would have as much chance of surviving as a scoop of ice cream dropped into a furnace.
As the sun moves across the sky it spends roughly two hours when it is directly above your solar panel, anything more than that and it begins to move away from the direct view of panel and such is how the efficiency of the solar panel drops off.

There you go; the typical Nigerian mentality.
Are you saying that because I am going to build it, therefore it won't last and the mechanical parts of the tracker will fail after two years? Like hell you sure sounded as sure as you could ever be.
What will make it fail?
I bet you aint into building technical stuffs, that dopey remark you just made sure clinches it. You definitely sound to me like a theoretical man..

If it weren't for your post, I'd already chosen elective mutism. After all, I have tried different cables with different current strengths and differing wire types. I'm speaking from experience not textbook stuff. The books are for guidance; the real world varies, even with identical equipment under comparable conditions. The solar forum is relatively new to me but electrical systems and electronics are not. I simply offered advise on what is safe rather than what "works". No worries, it won't happen again.

Thanks Abu and Chris

I am sure you based your conclusion on some information you did not supply.
What loads does he intend to power?
How many hours for each load.
Multiply the load by the hours.
Add up your totals and that gives you your watt hours.
Divide that number by the hours of peak sunshine (anywhere from 4 to 6 hours)
That will give you how many watts you need in panels.
Now the calculation for the batteries will be taken off your total watt hours and then factor in your depth of discharge.
I hope this helped

temizee I will issue a disclaimer. Without knowing the loads I can't give you an answer.

Now for my educated guess. 24 V system will need an 80 amp charge controller with 2 kw in panels.
Based on some of the smaller systems I have installed if you manage it well, it should be more than adequate

At my friend's house imagine an installer installing 8 pieces of 80watt panel on a 24v 800ah setup!!! he also put some crazy heatsink in a box n fix it on d wall calling it charge controller grin grin grin it doesn/t look like pwm/mppt and d worst part is he collected a very HUGE amount of money.
It would be better if he collects more money and he does a satisfying job..........don't know y some local made installer does rubbish n call it job

Guess u are diy person? Actually i did like to refer you to professional installers in d house (richmond,c0ogumo n more) what is yr location? Ideally 12v system is cool for simple house load u will need to know yr total house load if it exceeds 500watt/h then i will advice u to go for 24v system..........
NOW ANS. TO YR QUE.Your inverter system will determine d kind of solar setup. if itz 12v u go for solar panel like 80,90,100,130,upto 180 watt if itz 24v system then i will advice u to go for 200watt,230,250solar panel
Yr total output current from solar panels determines CC u will need
