Thanks for your answers . Are really helpfull. The question is theoreticall . For a long time i am searching for an answer.

Ι will rephrase my question : Suppose we want to put our panels in a slope ground lets say 30 degrees. Our panels has 40 degrees angle. The inclination of the ground does play role in losses of the panels? is rellative the inclination of the ground with panles angle? Thanks

any idea? any help?

Hello everyone, My question : if we want to install a ground mount system in a slope 10 degrees this affect the efficiency of the pannels? How we can calculate the right angle of the panels with this 10 degrees slope?(or any slope my location 40.6401° N, 22.9444° E) Thanks

Well I think that temperature correction factor plays role only if we are close to the charge controller maximum voltage? For minimum temperature -10 and maximum about 70 degrees I made two different calculations .First with temp correction factor and the second without it. Both 2 calculations...

So with this beautiful example we can design any system with suitable panels and mppt inverter. I guess the same procedure is for mppt solar chargers? Also (correct me if i am wrong)we can use Panasonic 330 w if we wire 2s4p in every mppt because 2*71 = 142 v < 145 v and 4*6.08 = 24.32A << 80 A...

Thanks for the help. But I can't understand how 25.6v occurs

Its just an exericise not particular project . I have calculate my solar capacity in my area (sun hours 4.5) . So the calculations are 10kwh consumption daily / efficiency of charge controller 0,97 / 4,5 = 2290 w. If i devide with 360w per panel its 6.36 panels round up 7. If i change the...

yeah is it avaliable on pdf format? Where i can find it?

So in my case how we can size the system? Can we assume a charge rate for this example? Thanks

Hi I am new in the forum . Here is my question : Which is the process to choose a mppt charge controler ? Fore example I have batteries of (200Ah , 12 v each) my system is 24 v and i will put 7 panels of 360W -24V (Vmp 38.4 V Imp 9.38 A VOC = 47,4 iSC 10.24 A ) Thanks
