400W Polycrystalline Solar Panel (Generic / Standard Series)

Product Overview

The 400W Polycrystalline Solar Panel is a workhorse of the solar industry, designed to provide high power output at a competitive price point. Available through Powernest Limited, this monofacial (single-sided) panel is composed of multiple silicon crystals, giving it the signature blue-speckled appearance. With an 18% module efficiency, it offers a balanced footprint-to-power ratio, making it ideal for large residential rooftops, off-grid farms, and industrial solar arrays where space is available and budget optimization is key.

Key Features

• Cost-Effective Power: Offers one of the best price-per-watt ratios on the market, allowing for larger total system sizes without proportional increases in budget.

• 18% Conversion Efficiency: Utilizes high-grade polycrystalline cells that convert 18% of available sunlight into usable electricity—perfect for high-irradiance regions.

• Rugged Monofacial Design: The traditional monofacial glass-and-backsheet construction is highly reliable and simplified for standard mounting on rooftops or ground racks.

• Heavy-Duty Frame: Built with a 35mm anodized aluminum alloy frame, providing structural rigidity against high winds (up to 2400Pa) and heavy snow loads (up to 5400Pa).

• High-Transparency Tempered Glass: Features 3.2mm anti-reflective, low-iron tempered glass that maximizes light absorption while protecting the cells from hail and debris.

• All-Weather IP67 Junction Box: Equipped with an IP67-rated waterproof junction box and bypass diodes to minimize power loss caused by partial shading or debris.

• Standard Compatibility: Designed with standard MC4-compatible connectors, ensuring easy integration with any 24V or 48V solar system and a wide range of MPPT controllers.
