 What Is the Solar Load Calculation Formula?

The solar load calculation formula means that you will be able to calculate how much electricity you will use daily and then size your solar system based on this calculation. Dozens of things are taken into account in this: all your household appliances such as fans, lights, refrigerators, etc. How many hours will these be used per day? The watt power of each appliance, how many hours of the day is the sun available?

How to Use the Solar Load Calculation Formula for Your Home or Office

You can use the solar load calculation formula for your home or office to find out its shoreline according to the given method.

Step 1: List all electrical appliances

Example:

🌀 3 fans × 70 watts = 210 watts
💡 5 LED lights × 15 watts = 75 watts
🧊 1 refrigerator = 300 watts
📺 1 TV = 100 watts
🔢 Total: 685 watts

Step 2: Write down the daily usage hours of each appliance

🌀 Fans = 8 hours
💡 Lights = 6 hours
🧊 Fridge = 24 hours
📺 TV = 4 hours

Step 3: Find the energy consumption of each appliance (watts × hours)

🌀 Fans: 210 watts × 8 = 1680 watts/hour
💡 Lights: 75 watts × 6 = 450 watts/hour
🧊 Refrigerator: 300 watts × 24 = 7200 watts/hour
📺 TV: 100 watts × 4 = 400 watts/hour
🔢 Total = 9730 watts/hour or 9.73 kilowatt-hours (kWh)

Step 4: Determine the size of the solar panels

Pakistan generally gets 5 hours of full sunlight per day.

Formula:

⚡ Required energy ÷ Solar hours = Required panel power
📊 9.73 kWh ÷ 5 = 1.946 kW ≈ 2 kW solar system

This means that a minimum of 2 kW solar system is required to power your home.
