Rixing Electronics QJM390-390W Monocrystalline Solar Panel
QJM390-144H | Monocrystalline | 144 Cells | Mono | 1500V System Voltage
Product Overview
The Rixing Electronics QJM390-144H is a high-performance monocrystalline solar panel designed for residential and commercial energy systems. This 390-watt panel delivers reliable power output with an impressive 19.32% efficiency rating. It features 144 premium monocrystalline cells arranged in a durable 2015x1002x40 mm frame. The panel operates effectively across a wide temperature range from -45°C to 85°C. Its robust construction includes anti-reflection tempered glass and an anodized aluminum frame for long-term durability. The IP67-rated junction box ensures protection against dust and water ingress. This solar panel is ideal for grid-tie, off-grid, and hybrid solar applications. It supports a maximum system voltage of 1500V for flexible system design. The MC4 connectors provide secure and weather-resistant cable connections. With a 10-year product warranty and 1-year power warranty, this panel offers strong value. The panel also maintains 97% power output after one year and 80.2% after 25 years. Its low degradation rate of 0.79% annually ensures consistent energy generation over decades.

Extreme Weather Durability: Operates safely from -45°C to 85°C with anti-reflection tempered glass and reinforced framing.
Flexible System Design: Supports up to 1500V maximum system voltage for versatile residential and commercial installations.
Secure Electrical Connections: Features IP67-rated junction box and MC4 connectors for weather-resistant, safe power transmission.
How It Works
The Rixing Electronics QJM390-144H solar panel converts sunlight into usable electricity through the photovoltaic effect. Its 144 monocrystalline cells absorb photons from solar radiation and generate electron flow. This direct current is then collected and transmitted via MC4 connectors to an inverter or battery system. The panel's anti-reflection coating maximizes light absorption while minimizing energy loss. The tempered glass front protects internal components from environmental damage. The anodized aluminum frame provides structural integrity and heat dissipation. Temperature coefficients ensure stable performance even under varying thermal conditions. The junction box houses bypass diodes to prevent hot spots during partial shading. Overall, this system delivers consistent, efficient energy for diverse power needs.
Photon Absorption: Monocrystalline cells absorb solar photons to excite electrons and generate direct current electricity.
Current Collection: Electron flow is collected through internal busbars and transmitted via MC4 connectors to external systems.
Heat Management: The anodized aluminum frame dissipates heat while temperature coefficients maintain stable output across conditions.
