The first step is to define your specifications. The most important specification for such a system is the acceptable risk of outage. If I’m to be executed if the power goes out, I’m going to specify a larger panel and battery. If an occasional or even nightly outage is acceptable, the panel and battery can be much (>100X ?) smaller.

Is this a school/college project?
You say you have to design the system. What is your approach so far?

thankyou for the reply

I hope the picture below will give u a clarity i have selected the BMS, Battery, Stepup the only thing i want to design is the solar pannel which will charge the battery and keep the system always powered.

The total system is dependent on the battery which will be charged in the daylight and the system will use the battery on night time when there is no sunlight
