What Voltage Does a 255W 15A Solar Panel Generate Key Insights Applications

Discover how to calculate voltage output for 255W 15A photovoltaic panels and their real-world applications in renewable energy systems.

Understanding the 255W 15A Solar Panel Specifications

When evaluating a 255W 15A photovoltaic panel, voltage is a critical parameter for system design. Let's break down the math:

• Power (W) = Voltage (V) × Current (A)
• Voltage (V) = Power (W) ÷ Current (A)

Using this formula, a 255W panel with a 15A current generates approximately 17 volts under standard test conditions (STC). However, real-world factors like temperature and sunlight intensity can shift this value by ±10%.

Key Variables Affecting Voltage Output

Factor	Impact on Voltage
Ambient Temperature	High temps reduce voltage
Sunlight Intensity	Low light lowers output
Panel Age	0.5-1% annual efficiency loss

Industry Applications of 255W Solar Modules

These mid-range panels shine in three key sectors:

• Residential Rooftops: 4-6 panels can power a refrigerator for 8 hours
• Telecom Towers: 12-panel arrays provide reliable off-grid power
• Agricultural Systems: Powers irrigation pumps in remote farms
