1. What is a Solar Power Calculator by Address?

Definition: This calculator estimates the daily energy production of a solar panel system based on panel power, sunlight hours, and performance ratio.

Purpose: It helps homeowners and solar installers estimate potential solar energy generation for a specific location.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ E = P \times H \times PR \]

Where:

Explanation: The panel power is multiplied by sunlight hours and performance ratio to estimate daily energy output.

3. Importance of Solar Power Calculation

Details: Accurate solar power estimation helps determine system sizing, return on investment, and energy savings potential.

4. Using the Calculator

Tips: Enter panel power in kW, average daily sunlight hours (default 4.5), and performance ratio (default 0.75). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find average sunlight hours for my address?
A: Use solar maps or local meteorological data. Many solar calculators provide location-based estimates.

Q2: What's a typical performance ratio?
A: Most systems have PR between 0.70-0.80, accounting for losses from temperature, wiring, dirt, etc.

Q3: Should I use peak or nominal panel power?
A: Use the panel's rated power under standard test conditions (STC), typically listed in kW.

Q4: Does this calculate daily or annual production?
A: This calculates daily production. Multiply by 365 for annual estimate.

Q5: How accurate is this calculator?
A: It provides estimates. For precise calculations, consult a solar professional with detailed site data.
