• Module Efficiency ~20 % – 23 %

• Power Tolerance Typically 0 ~ +3 %

• Maximum System Voltage ~1500 V DC

• Operating Temp Range ~-40 °C to +85 °C

• 📦 Mechanical & Construction

• Solar Cell Type: PERC or high-efficiency monocrystalline

• Cell Count: Usually ~120 cells (some 144 cells)

• Dimensions: ~1900 × 1130 × 30–40 mm (some variants ~2100 × 1046 × 35 mm)

• Weight: ~23 – 25 kg

• Front Glass: Tempered solar glass (often IP-rated)

• Frame: Anodized aluminum alloy

• Connector Type: MC4 or compatible

• 📊 What These Specs Mean

• 450 W rating is the peak output under ideal lab conditions with standard sunlight. Actual output varies with temperature, sun angle, and shading.

• Higher voltage (~30-40 V) panels are common for grid-tie and battery charging systems.

• Current (~10-14 A) affects how you size your inverter or charge controller.

• 📷 Example Images of 450 W Solar Panels

• These images show typical 450 W monocrystalline solar panels with tempered glass and aluminum frames (images are representative examples).

• 📌 Typical Uses

• Residential solar arrays (roof-mounted)

• Off-grid battery systems (with appropriate controllers)

• Commercial installations (larger wattage per panel reduces system size)

• RVs, cabins, outdoor power setups
