1. What is a 12V 100W Solar Panel Calculator?

Definition: This calculator estimates the energy output of a 100-watt solar panel based on sunlight hours.

Purpose: It helps solar energy users understand how much electricity their panel can generate under different sunlight conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Output — Energy produced (kilowatt-hours)
• 100 — Panel wattage (watts)
• Hours — Peak sunlight hours (hours)
• 1000 — Conversion factor (watts to kilowatts)

Explanation: The panel's wattage is multiplied by sunlight hours, then divided by 1000 to convert to kilowatt-hours.

3. Importance of Solar Output Calculation

Details: Accurate output estimation helps in sizing solar systems, calculating energy savings, and planning battery storage needs.

4. Using the Calculator

Tips: Enter the number of peak sunlight hours your location receives. Typical values range from 3-6 hours depending on location and season.

5. Frequently Asked Questions (FAQ)

Q1: What are "peak sunlight hours"?
A: This refers to the equivalent number of hours when sunlight intensity averages 1000W/m², not just daylight hours.

Q2: Is this the actual output I'll get?
A: This is theoretical maximum. Real-world output may be 10-30% less due to temperature, angle, and system losses.

Q3: Can I use this for multiple panels?
A: Yes, multiply the result by your number of panels (e.g., 3 panels would triple the output).

Q4: How do I find sunlight hours for my area?
A: Check solar insolation maps or use tools like NASA's solar database for your location.

Q5: What about battery storage?
A: This calculates production only. Battery capacity depends on your energy usage patterns.
