1. What is the Watt to kWh Conversion?

The Watt to kilowatt-hour (kWh) conversion calculates the energy output of solar panels over time. While watts measure instantaneous power, kilowatt-hours measure energy consumption or production over time.

2. How Does the Calculator Work?

The calculator uses the energy conversion formula:

Where:

• \( W \) — Power output in watts
• \( h \) — Time in hours
• 1000 — Conversion factor from watts to kilowatts

Explanation: This converts the power rating of solar panels into actual energy produced over a specific time period.

3. Importance for Solar Panels

Details: This calculation helps solar panel owners estimate their energy production, calculate potential savings, and size their solar systems appropriately.

4. Using the Calculator

Tips: Enter the wattage rating of your solar panel system and the number of hours it operates. For daily production, use peak sun hours for your location.

5. Frequently Asked Questions (FAQ)

Q1: How many kWh does a 100W solar panel produce?
A: A 100W panel produces about 0.1 kWh per hour. Over 5 hours, it would produce 0.5 kWh.

Q2: What's the difference between kW and kWh?
A: kW measures power (instantaneous), kWh measures energy (power over time). 1 kW for 1 hour = 1 kWh.

Q3: How do I calculate monthly solar production?
A: Multiply daily kWh by number of days in month. Account for seasonal variations in sunlight.

Q4: What affects solar panel output?
A: Sunlight intensity, panel angle, temperature, shading, and panel efficiency all affect actual output.

Q5: How accurate is this calculation?
A: It provides theoretical maximum. Real-world output is typically 70-90% of theoretical due to various factors.
