which solar cell size is best. 3x6 o 6x6?

[aliraj]

Thankx for your good information, so what im doing wrong, why DIY pannels are not allowed? what is wrong with them? what is the security risk? and what is nice way to do this job?, im planing this project for thar area that have electricity only for few hours in 24 hours, and temprature is now a days like 45 c o more, so what is your segustion, i really ariciating this forum n your kind help
Thankx

Really thankx for a quick reply, actually im planing to make a 5kv solar energy system with grid on, for 5 kv how much solar cells i need, in this case i think 6x6 are best?

DIY panels will never be allowed for grid connection, or attached or connected to any insured stru ture. Sorry. They are fine for test and research.

I hope you are not in the USA because you are wasting your time and money. Here in the USA you will not be allowed to make you own panels and connect to the commercial grid. You would not even be able to pull the building permit without listed panels and equipment.

I assume you are not in the USA but 5KW of home built panels are not worth it anywhere.
By the time you purchase materials and assemble you can generally buy production panels that will cost less, perform better, last 5-10 times longer and are certified for use on your home.

As Rich correctly points out a 6 x 6 cells has twice the current density, thus twice the power density. If you take the larger 6x6 cells and put x number of them in a frame, then make two panels with 3x3 cells of equal number of cells the power of the 6 x 6 will equal the power of the 2-3x3 cell frames. However the 2-3x3 frames will occupy more square area then the single 6x6 cell frame. It comes down to power density.

Depends on how much power you want to get out of it. A 6x6 will produce twice the power of a 3x6.
The decision is more a function of power you want, desired voltage, and panel size.

im new in solar system, i want to make my own solar panel for home use, so my first question is wich solar cell size is best 3x6 o 6x6? normaly 3x6 have 2 busbar and 6x6 have 3 busbar, also want to know is busbar effect on solar output? Really aprciate any help
This is really a nice forum, im here after a long search and visting many many forums,
