1. What is the Integral Energy Solar Calculator?

The Integral Energy Solar Calculator estimates the potential energy production from a solar photovoltaic system based on area, yield, solar irradiation, and performance ratio.

2. How Does the Calculator Work?

The calculator uses the solar energy equation:

Where:

• \( A \) — Area of solar panels (m²)
• \( r \) — Yield or efficiency of solar panels (%)
• \( H \) — Solar irradiation (kWh/m²)
• \( PR \) — Performance ratio (decimal between 0 and 1)

Explanation: The equation calculates the theoretical energy production by multiplying the physical area by the panel efficiency, available sunlight, and system performance factor.

3. Importance of Solar Energy Calculation

Details: Accurate energy production estimation is crucial for sizing solar systems, calculating return on investment, and planning energy needs.

4. Using the Calculator

Tips: Enter area in square meters, yield as percentage, irradiation in kWh/m², and performance ratio as decimal between 0-1. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical performance ratio?
A: Most systems have PR between 0.75-0.85, accounting for losses from temperature, wiring, inverters, etc.

Q2: How do I find solar irradiation for my location?
A: Use solar maps or databases like NASA's POWER or PVGIS which provide location-specific irradiation data.

Q3: What affects solar panel yield?
A: Panel technology (mono/polycrystalline, thin-film), temperature, shading, and orientation all affect yield.

Q4: Is this calculation for daily or annual energy?
A: The units depend on your input. For annual energy, use annual irradiation data; for daily, use daily values.

Q5: How accurate is this calculation?
A: It provides a theoretical maximum. Actual production depends on installation quality, maintenance, and local conditions.
