1. What is Solar Panel Calculation?

Solar panel calculation helps determine the number of solar panels needed to meet your home's energy requirements based on your location's sunlight availability and panel specifications.

2. How Does the Calculator Work?

The calculator uses the solar panel formula:

Where:

• Daily Energy Use — Your household's daily electricity consumption (kWh/day)
• Daily Sun Hours — Average sunlight hours per day at your location
• Panel Wattage — Power rating of individual solar panels (W)

Explanation: The calculation first determines the required system size in kW, then divides by panel wattage to get the number of panels needed.

3. Importance of Solar Panel Calculation

Details: Accurate solar panel calculation is crucial for designing an efficient solar power system that meets your energy needs while optimizing costs and space requirements.

4. Using the Calculator

Tips: Enter your average daily energy consumption in kWh, the average daily sun hours for your location in India, and the wattage of the solar panels you're considering. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the average daily sun hours in India?
A: Most regions in India receive 4-6 hours of peak sunlight daily, though this varies by season and location.

Q2: How do I calculate my daily energy use?
A: Check your electricity bill for monthly consumption, then divide by 30 to get daily average in kWh.

Q3: What are typical panel wattages available?
A: Common residential solar panels range from 300W to 500W, with 400W being a popular choice.

Q4: Should I consider system losses?
A: Yes, it's recommended to add 10-20% extra capacity to account for system inefficiencies and future needs.

Q5: Are there government incentives for solar in India?
A: Yes, various central and state government schemes offer subsidies and incentives for residential solar installations.
