for help: I want to learn basic configuration of off-grid solar system. I know off-grid solar system consists of panels, inverters, batteries and charge controller.

Could anyone help me with the calculation for the panel, and batteries? If I want to configurate for a 1.6kw off-grid system for Air conditioner, how to choose panel, battery and other accessories?

Thanks in advance.
 
To figure out how much battery capacity it will require to run an appliance for a given time, multiply the appliance wattage, times the number of hours it will run to yield the total watt-hours. Then divide by the battery voltage to get the amp hours.

For example, running a 60-watt lamp for one hour uses 60 watt-hours. If a 12-volt battery is running the light it will consume 5 amp-hours (60 watt-hours divided by 12 volts equals 5 amp-hours)
 
yet how can I calculate hours for the battery? If the location is in Pakistan, summer day time from 9am to 5 pm. Where can I get the radiation level and weather of the place and transfer the info into hours for the battery.

Pls tell me if you know.

Thanks in advance
