1. What is a Yearly kWh Calculator for Solar Panels?

Definition: This calculator estimates the annual energy production (in kilowatt-hours) of solar panels based on their daily output.

Purpose: It helps solar energy system owners and planners understand their potential yearly energy generation from solar panels.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Yearly kWh — Total energy production in one year (kilowatt-hours)
• Daily kWh — Average daily energy production (kilowatt-hours)
• 365 — Number of days in a year

Explanation: The calculator multiplies your system's average daily output by 365 days to estimate annual production.

3. Importance of Yearly kWh Calculation

Details: Knowing your system's yearly output helps with energy planning, financial calculations, and understanding your return on investment for solar panels.

4. Using the Calculator

Tips: Enter your system's average daily kWh production. This can be obtained from your solar monitoring system or estimated based on your system size and location.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate yearly kWh for solar panels?
A: It helps estimate annual energy production for financial planning and to understand your system's performance.

Q2: Is the calculation accurate for all locations?
A: This assumes consistent daily production. Actual production varies by season, weather, and location.

Q3: Should I use peak or average daily production?
A: Use your system's average daily production over time for the most accurate yearly estimate.

Q4: How do I find my daily kWh production?
A: Check your solar monitoring system, or estimate by multiplying system size (kW) by average daily sun hours in your area.

Q5: Does this account for system degradation?
A: No, solar panels typically degrade about 0.5-1% per year. Consider this for long-term projections.
