1. What is Solar Load Calculation?

Solar load calculation determines the power requirements for a solar energy system based on your total energy consumption and available sunlight hours. It helps in sizing solar panels appropriately for your needs.

2. How Does the Calculator Work?

The calculator uses the solar load equation:

\[ Load = \frac{Total\ Wh}{Sun\ Hours} \]

Where:

Explanation: The equation calculates the required solar panel wattage by dividing your total daily energy needs by the average sunlight hours available.

3. Importance of Solar Load Calculation

Details: Accurate solar load calculation is crucial for designing efficient solar power systems that can meet your energy requirements without oversizing or undersizing the system.

4. Using the Calculator

Tips: Enter your total daily energy consumption in watt-hours and the average sunlight hours at your location. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my total watt-hours?
A: Multiply the wattage of each appliance by its daily usage hours, then sum all values.

Q2: Where can I find sun hours for my location?
A: Check solar insolation maps or consult local solar installation companies for accurate data.

Q3: Does this account for system losses?
A: No, this is a basic calculation. For real systems, add 20-30% to account for inefficiencies.

Q4: How does seasonality affect the calculation?
A: Use the lowest sun hours for your location to ensure year-round performance.

Q5: What about battery storage?
A: This calculation is for direct solar panel sizing. Battery requirements need separate calculation.
