Solar Energy Conversion Formula:
From: | To: |
The Solar kW to kWh conversion calculates the expected energy production of a solar system by accounting for system size, available sunlight, and system efficiency. It helps estimate daily energy generation from photovoltaic systems.
The calculator uses the solar energy conversion formula:
Where:
Explanation: The equation accounts for the system's capacity, available sunlight, and losses due to temperature, wiring, inverters, and other factors.
Details: Accurate energy production estimation is crucial for sizing solar systems, calculating return on investment, and understanding energy offset potential.
Tips: Enter system size in kW, peak sun hours for your location (typically 3-6 hours depending on region), and system efficiency (default is 0.75). All values must be valid (positive numbers).
Q1: What are peak sun hours?
A: Peak sun hours represent the equivalent number of hours per day when solar irradiance averages 1,000 watts per square meter.
Q2: What is typical solar system efficiency?
A: Most grid-tied systems have 75-85% efficiency due to various losses (inverters, wiring, temperature, etc.).
Q3: How do I find peak sun hours for my location?
A: Check solar maps or databases like NREL's PVWatts Calculator for location-specific data.
Q4: Does this account for seasonal variations?
A: No, this provides a daily estimate. For annual production, multiply by 365 using average sun hours.
Q5: Should I use DC or AC rating for kW?
A: Use the DC rating (panel nameplate capacity) for most accurate results.
