- Four 10-watt LED lights, used for 4 hours daily.
- A refrigerator consuming 150 watts, running continuously (24 hours/day).
- A laptop using 50 watts for 2 hours daily.
- A small water pump consuming 200 watts for 30 minutes daily.
To calculate the daily energy consumption of each appliance, we use the following formula:
Energy (watt-hours) = Power (watts) x Time (hours)
For example, the four LED lights consume: 4 lights10 watts/light
4 hours = 160 watt-hours. The refrigerator consumes

2 hours = 100 watt-hours. The water pump uses
200 watts
- 0.5 hours = 100 watt-hours.
Total Daily Energy Consumption and Sizing Solar Panels
Summing the energy consumption of all appliances gives us a total daily energy demand: 160 + 3600 + 100 + 100 = 3960 watt-hours. To account for cloudy days and system inefficiencies, we add a safety margin. A common safety margin is 25-50%. Let’s use 30%. Therefore, our adjusted daily energy requirement is: 3960 watt-hours – 1.30 = 5148 watt-hours.Assuming an average of 5 peak sunlight hours per day, we can calculate the required solar panel wattage:
Required Solar Panel Wattage = Total Daily Energy Demand / Peak Sunlight Hours
Required Solar Panel Wattage = 5148 watt-hours / 5 hours = 1029.6 watts
We should round this up to the nearest commercially available size, such as a 1050-watt solar panel system.
Battery Capacity Calculation
The battery capacity needs to store enough energy to supply power during nighttime and cloudy days. Let’s assume we need to store enough energy for two days. Therefore, the required battery capacity is:
Required Battery Capacity (watt-hours) = Total Daily Energy Demand
Number of Backup Days
Required Battery Capacity (watt-hours) = 5148 watt-hours
2 days = 10296 watt-hours
This calculation assumes 100% battery efficiency, which is not realistic. Inverter and battery losses typically reduce usable capacity by 10-20%. Accounting for a 15% loss, we need a battery capacity of approximately 12000 watt-hours.
