1. What is a Solar Power Requirement Calculator for India?

Definition: This calculator estimates the solar power system size needed based on your daily energy consumption and local peak sun hours.

Purpose: It helps homeowners and businesses in India determine the appropriate solar panel capacity for their energy needs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Solar power requirement (kW)
• \( L \) — Daily load (kWh)
• \( H \) — Peak sun hours (hours)

Explanation: The daily energy consumption is divided by peak sun hours to determine the solar system size needed to meet that demand.

3. Importance of Solar Power Calculation in India

Details: Proper solar sizing ensures optimal energy production, cost savings, and efficient use of rooftop space in Indian conditions.

4. Using the Calculator

Tips: Enter your daily electricity consumption in kWh and local peak sun hours (default 4.5 hours for most of India). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are peak sun hours in India?
A: Most Indian locations receive 4-6 peak sun hours daily, with northern regions getting more in summer and southern regions more consistent year-round.

Q2: How do I find my daily load?
A: Check your electricity bill for monthly consumption and divide by 30, or use our Load Calculator tool.

Q3: Does this include system losses?
A: No, consider adding 20-30% to the calculated requirement to account for system inefficiencies and degradation.

Q4: What about battery storage?
A: This calculates solar panel requirement only. For battery sizing, use our Solar Battery Calculator.

Q5: How accurate is this for different Indian cities?
A: Very accurate when using location-specific sun hours. Delhi averages 5.5, Mumbai 5.2, Chennai 5.0, Bangalore 5.1 peak sun hours.
