Product Overview

What This Product Is

A 420W to 460W half-cell monocrystalline solar panel with PERC technology, designed for residential and commercial solar installations. The panel uses two separate cell arrays, each with 6 shorter strings, reducing mismatch loss and improving performance under partial shading. It features a positive power tolerance of 0 to +5W, high conversion efficiency up to 20.9%, and low LID with first-year degradation under 2% and 0.55% annually from year 2 to 25. The module is built for stable long-term output with solid PID resistance and lower operating temperature.

Comparison

How It Compares With the Alternatives

Standard monocrystalline panelHalf-cell design reduces mismatch loss and improves shading response, but may have higher initial cost
Full-cell PERC panelBetter partial shading performance and lower operating temperature, but same efficiency range
Polycrystalline panelHigher efficiency and lower degradation, but lower performance under shading conditions
Standard half-cell panel without PID resistanceSuperior long-term output due to optimised cell process, but requires more advanced manufacturing
Use Guide

Getting It Working on Site

1

Install panels to avoid shading from nearby structures or trees

2

Ensure mounting system allows for proper airflow behind the panel to reduce operating temperature

3

Connect panels in series with matching string lengths to maintain voltage balance

4

Monitor system performance regularly to detect early signs of degradation

5

Keep the panel surface clean to maintain maximum light transmission
