1. What is kWh from Solar Panels Calculator?

Definition: This calculator estimates the energy production in kilowatt-hours (kWh) from solar panels based on their wattage and operating hours.

Purpose: It helps solar panel owners and installers estimate energy production for system sizing and performance evaluation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( kWh \) — Energy produced (kilowatt-hours)
• \( Wattage \) — Power rating of solar panels (watts)
• \( Hours \) — Duration of sunlight exposure (hours)

Explanation: The formula converts watt-hours to kilowatt-hours by dividing by 1000.

3. Importance of Solar Energy Calculation

Details: Accurate energy estimation helps in system design, cost analysis, and predicting return on investment for solar installations.

4. Using the Calculator

Tips: Enter the solar panel wattage (sum of all panels if multiple) and estimated peak sunlight hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's typical wattage for residential solar panels?
A: Most residential panels range from 250W to 400W each. Commercial panels may be higher.

Q2: How many peak sunlight hours should I use?
A: This varies by location. Average is 4-6 hours in most regions, but check local solar data.

Q3: Does this account for system efficiency losses?
A: No, this is theoretical maximum. Actual production will be 10-25% less due to various factors.

Q4: How do I calculate for multiple panels?
A: Multiply single panel wattage by number of panels, or enter total system wattage.

Q5: Can I use this for battery sizing?
A: Yes, the kWh result helps determine battery bank capacity needed to store the energy.
