Solar Power Formula:
From: | To: |
Definition: This calculator estimates the power output of a solar generator based on panel area, efficiency, solar irradiation, and system performance ratio.
Purpose: It helps solar energy professionals and homeowners determine the potential wattage output of solar panel systems.
The calculator uses the formula:
Where:
Explanation: The formula calculates the theoretical power output by considering panel characteristics and environmental factors.
Details: Accurate wattage estimation ensures proper system sizing, energy production forecasting, and return on investment calculations.
Tips: Enter panel area in m², efficiency (default 0.15 for 15%), irradiation (default 1000 W/m² for full sun), and performance ratio (default 0.75). All values must be > 0.
Q1: What is solar panel efficiency?
A: Efficiency measures how much sunlight is converted to electricity. Typical values range from 15-22% for commercial panels.
Q2: What's standard solar irradiation?
A: 1000 W/m² represents peak sunlight conditions (1 sun). Actual values vary by location and weather.
Q3: What affects performance ratio?
A: System losses from wiring, inverters, temperature, dust, and shading reduce the performance ratio below 1.
Q4: How do I find my panel area?
A: Measure length × width of panels or check manufacturer specifications.
Q5: Does this include battery storage?
A: No, this calculates raw power generation. Storage capacity requires separate calculations.
