1. What is Solar Panel Capacity Calculation?

Solar panel capacity calculation helps estimate the daily energy production of a solar photovoltaic system based on panel capacity, sunlight hours, and system efficiency. This is particularly important in India where sunlight conditions vary across regions.

2. How Does the Calculator Work?

The calculator uses the solar energy formula:

Where:

• \( Panel\ kWp \) — Solar panel capacity in kilowatt-peak
• \( Average\ Sun\ Hours \) — Average peak sun hours per day
• \( Efficiency \) — System efficiency factor (typically 0.75-0.85)

Explanation: The equation calculates expected daily energy production based on system capacity and local solar conditions.

3. Importance of Solar Energy Calculation

Details: Accurate solar energy calculation is crucial for sizing solar systems, estimating energy production, calculating return on investment, and planning energy consumption.

4. Using the Calculator

Tips: Enter panel capacity in kWp, average sun hours (India typically 4-5 hours), and system efficiency (default 0.75). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is kWp in solar panels?
A: kWp (kilowatt-peak) is the peak power output of a solar panel system under standard test conditions.

Q2: What are typical sun hours in India?
A: India typically receives 4-5 peak sun hours daily, varying by region and season.

Q3: What affects solar system efficiency?
A: Efficiency is affected by temperature, dust, shading, inverter efficiency, wiring losses, and panel degradation.

Q4: How accurate is this calculation?
A: This provides an estimate. Actual production may vary due to weather conditions, panel orientation, and maintenance factors.

Q5: Can I use this for off-grid systems?
A: Yes, but you'll need to account for battery storage efficiency and depth of discharge for complete off-grid planning.
