1. What is Solar Load Calculation?

Solar Load Calculation determines the size of solar power system needed to meet your daily energy requirements based on available sunlight hours in your location.

2. How Does the Calculator Work?

The calculator uses the solar load formula:

Where:

• \( Daily\ kWh \) — Your daily energy consumption in kilowatt-hours
• \( Sun\ Hours \) — Average peak sunlight hours at your location

Explanation: The formula calculates the required solar system size (in kW) by dividing your daily energy needs by the average sunlight hours available.

3. Importance of Solar Load Calculation

Details: Accurate solar load calculation is essential for designing efficient solar power systems that can meet your energy needs without over- or under-sizing the system.

4. Using the Calculator

Tips: Enter your daily energy consumption in kWh and the average sun hours for your location. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my daily kWh usage?
A: Check your electricity bill for monthly kWh usage and divide by number of days in the billing period.

Q2: What are typical sun hours for my area?
A: Sun hours vary by location and season. Many solar maps provide average daily sun hours for different regions.

Q3: Does this account for system inefficiencies?
A: No, this is a basic calculation. Real-world systems should include efficiency factors (typically 20-30% more capacity needed).

Q4: What if my usage varies by season?
A: Calculate based on your highest usage period to ensure year-round coverage, or size for average usage and supplement with grid power.

Q5: How does this relate to number of solar panels?
A: Divide the kW result by individual panel wattage (e.g., 3kW system = 3000W / 300W panels = 10 panels).
