Need help with some calculations for an Off grid installation

[Diri]

Dear users,

I'm planning to build a mini solar farm (if I can say like that) to a ground of 2200m2.

Please help me understand the following:

If I install 400x solar panels by 550w ( efficiency 22,5%) and based 3 hours sunlight (18-25 degree) in my country, how much electricity will be generated per day?

From my calculation as this is 220kw installation then it should be 220kw x 3 hours= 660kw +/-... Is this right? (I'm aware that all this is approximate as many things may impact the production).

I read somewhere that a pannel from 550w will only generate 22,5% as that is its efficiency so that's why I'm confused.

Thank you very much.

No, 550w is the ideal max output of the PV panel. You are correct that 660 kilowatthours (kWh) is the average DC energy harvest per day except you will lose about a quarter of that in wire losses and inverter losses etc converting it to AC.
You are going to be generating some serious power with this size system and should figure on getting a real expert involved to do the interconnection to the utility.

I agree with solarix. A system that large requires both engineering and cooperation with any local electrical authorities.
