• Junction Box: Weatherproof (IP65/IP67-rated)

• 📌 What These Specs Mean

• 250 W rating is the maximum power the panel can produce under ideal sunlight and temperature conditions (Standard Test Conditions). Actual performance varies with sun intensity, temperature, and shading.

• Voltage (~30 V) and current (~8 A) figures help you choose the right charge controller or inverter (for a 24 V battery system, for example).

• Efficiency reflects how much of the sunlight hitting the panel is converted to electricity — higher efficiency means more watts per square metre of panel.

• 📌 Typical Uses

• Rooftop solar installations for homes or small businesses

• Off-grid systems (battery charging)

• RVs, caravans, boats

• Solar generators and portable setups
