Hi, i am learning to size a standalone solar power system. The system will consist of solar panels, charge controller, battery and inverter .

The following are the design criteria.

The system voltage is 12V.
The system must be able to provide power for 1 day without sunshine.
The total DC watt hours/day : 97.2 W (DC loads)
The total AC watt hours/day : 240 W (AC loads)
The total sunshine hours per day : 6 hours.
Battery depth of discharge : 0.7

Can anyone help me to size the correct solar panel, charge controller, battery and inverter please?

Thanks.
Wind23.

 

(I always love these oddly specific help requests. So what is the real story here? Is this a school assignment, or is your employer telling you to solve this?)

Anyway, you can answer it yourself, given all the details you list.
