Step 1: Assess Your Energy Requirements
You should start by finding out how much power you use in a day.
Create a list of all devices: Make a complete list of every electric appliance you use daily (orr an example, refrigerator, lights, laptop, etc.) with the power rating (watts) for each device. Here is an example
Refrigerator – 150W running 24 hours per day
Lights – 50W running 5 hours per day
Laptop – 50W running 3 hours per day
Now calculate your daily consumption. So for each thing on your list, just multiply the power (in watts) by the number of hours it's used each day. That'll give you the watts used per day for that item. Add all those up, and boom – you've got your total daily electric energy use.
