Assuming you have a refrigerator consuming 4.8 kWh daily, here’s how to estimate the size of your solar system:
- Daily Requirement: 4.8 kWh
- Average Sunlight Hours: Assume 5 hours
- Solar Panel Output: Assume each panel produces 300W
You need a solar array that can produce:
Required Output (kWh) = Daily Requirement / Sunlight hours
Required Output = 4.8 kWh / 5 hours = 0.96 kW
To find the number of panels:
Number of Panels = Required Output / Panel Output
Number of Panels = 0.96 kW / 0.3 kW = 3.2 panels
So, you would need approximately 4 solar panels, each rated at 300 watts, to run your refrigerator.
