1. What is a Solar Power Size Calculator?

Definition: This calculator estimates the required solar power system size based on your daily energy consumption and average solar hours.

Purpose: It helps homeowners and businesses determine the appropriate solar panel system size for their energy needs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Size} \) — Required solar power system size (kW)
• \( \text{Daily Consumption} \) — Your daily energy usage (kWh)
• \( \text{Solar Hours} \) — Average peak sunlight hours per day (h)

Explanation: The daily energy consumption is divided by the average solar hours to determine the system size needed to meet your energy requirements.

3. Importance of Solar Power Sizing

Details: Proper sizing ensures your solar system meets your energy needs, maximizes return on investment, and avoids over- or under-sizing.

4. Using the Calculator

Tips: Enter your daily energy consumption in kWh and average solar hours (default 4.5 hours). Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical solar hours?
A: Most locations average 4-6 peak sun hours per day. This varies by location and season.

Q2: How do I find my daily consumption?
A: Check your electricity bill for monthly kWh usage and divide by 30 for daily average.

Q3: Does this include battery storage?
A: No, this calculates the solar array size needed to offset your consumption during daylight hours.

Q4: Should I add a buffer to the calculated size?
A: Consider adding 10-20% to account for system losses and future energy needs.

Q5: What about panel efficiency?
A: This calculation assumes standard conditions. Higher efficiency panels would require slightly less physical space.
