1. What is a Solar Calculator for India?

Definition: This calculator estimates annual solar energy generation based on system size, using average sunlight hours for India.

Purpose: Helps homeowners and businesses estimate potential solar energy production for planning and ROI calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Generation — Annual energy production (kWh)
• Size — Solar system capacity (kW)
• 4 — Average daily sunlight hours in India
• 365 — Days in a year

Explanation: The formula calculates total annual production by multiplying system capacity by daily sunlight hours and number of days.

3. Importance of Solar Generation Estimation

Details: Accurate generation estimates help determine system sizing, financial returns, and payback periods for solar investments.

4. Using the Calculator

Tips: Enter your planned solar system size in kW. The calculator assumes 4 average sunlight hours per day (typical for most of India).

5. Frequently Asked Questions (FAQ)

Q1: Why use 4 hours for India?
A: This is the national average, though actual hours range from 3.5-5.5 depending on location and season.

Q2: How accurate is this estimate?
A: It provides a rough estimate. Actual generation depends on panel orientation, shading, and local weather.

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

Q4: Does this account for system losses?
A: No, actual generation will be about 10-15% lower due to temperature, dust, and inverter losses.

Q5: How does this translate to savings?
A: Multiply generation by your electricity rate (₹6-8/kWh typically) to estimate annual savings.
