1. What is the Solar Energy Formula?

The solar energy formula calculates the energy output from solar panels based on panel area, solar irradiance, efficiency, and time. It provides an estimate of the electricity generated by solar panels in kilowatt-hours (kWh).

2. How Does the Calculator Work?

The calculator uses the solar energy formula:

Where:

• \( E \) — Energy output (kWh)
• \( A \) — Panel area (m²)
• \( I \) — Solar irradiance (kW/m²)
• \( \eta \) — Efficiency (%)
• \( t \) — Time (hours)

Explanation: The formula calculates the total energy produced by multiplying panel area by solar irradiance, efficiency percentage, and time duration.

3. Importance of Solar Energy Calculation

Details: Accurate energy calculation is crucial for sizing solar power systems, estimating electricity generation, and evaluating the economic viability of solar installations in India.

4. Using the Calculator

Tips: Enter panel area in square meters, solar irradiance in kW/m², efficiency as a percentage, and time in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is typical solar irradiance in India?
A: India receives average solar irradiance of 4-7 kWh/m²/day, varying by region and season.

Q2: What is typical efficiency for solar panels?
A: Most commercial solar panels have efficiencies between 15-22%, with premium panels reaching up to 24%.

Q3: How does panel orientation affect energy output?
A: South-facing panels at optimal tilt angles maximize energy production in the northern hemisphere.

Q4: Are there losses not accounted for in this formula?
A: Yes, this formula doesn't account for temperature losses, shading, soiling, or inverter efficiency losses.

Q5: How accurate is this calculation for real-world applications?
A: This provides a theoretical maximum. Actual output is typically 10-20% lower due to various system losses and environmental factors.
