1. What is a Solar Power Calculator for India?

Definition: This calculator estimates daily solar energy production (in kWh) for photovoltaic systems in India.

Purpose: Helps homeowners and businesses estimate solar panel output based on system size.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( kWh \) — Estimated daily energy production (kilowatt-hours)
• \( Size \) — Solar system size (kilowatts)
• \( 4.5 \) — Average daily sun hours in India

Explanation: The formula multiplies system capacity by average daily sunlight hours to estimate production.

3. Importance of Solar Power Estimation

Details: Accurate estimation helps in system sizing, ROI calculation, and energy planning for solar projects.

4. Using the Calculator

Tips: Enter your solar system size in kW (typically 1kW to 100kW for residential/commercial systems).

5. Frequently Asked Questions (FAQ)

Q1: Why 4.5 sun hours for India?
A: This is the national average accounting for regional variations and seasonal changes in sunlight availability.

Q2: How accurate is this estimate?
A: It provides a rough average. Actual output depends on location, panel orientation, weather, and system efficiency.

Q3: What's a typical system size for homes?
A: Most Indian homes install 3kW-10kW systems depending on energy needs and roof space.

Q4: Does this include monsoon season reduction?
A: Yes, the 4.5 factor is an annual average that accounts for seasonal variations including monsoon.

Q5: How can I improve accuracy for my location?
A: Use region-specific sun hour data (e.g., 5.2 for Rajasthan, 4.0 for Kerala) if available.
