1. What is the Solar Panel kWh Calculator?

The Solar Panel kWh Calculator estimates the energy production of solar panels based on their power rating and operating time. It converts watts to kilowatt-hours (kWh), the standard unit for measuring electrical energy.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( kWh \) — Energy in kilowatt-hours
• \( P_{solar} \) — Solar panel power in watts (W)
• \( h \) — Time in hours

Explanation: The equation converts watt-hours to kilowatt-hours by dividing by 1000 (since 1 kWh = 1000 Wh).

3. Importance of Solar Energy Calculation

Details: Calculating solar energy production helps in sizing solar systems, estimating electricity generation, and evaluating the financial viability of solar installations.

4. Using the Calculator

Tips: Enter the solar panel's rated power in watts and the number of hours it will operate. For daily production, use average sunlight hours for your location.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between watts and kilowatt-hours?
A: Watts measure power (rate of energy use), while kilowatt-hours measure energy (power × time).

Q2: How many hours of sunlight should I use?
A: This varies by location and season. Average values range from 3-6 hours per day in most locations.

Q3: Does this account for system efficiency?
A: No, this calculates theoretical maximum. Actual production will be lower due to factors like temperature, shading, and inverter efficiency.

Q4: Can I use this for battery sizing?
A: Yes, the kWh result helps determine battery capacity needed to store solar energy.

Q5: How does this relate to my electricity bill?
A: Compare the kWh result with your monthly electricity usage to estimate how much solar can offset your bill.
