Alps Technology Inc. ATI 220 220W Polycrystalline 60-Cell Solar Panel
Model ATI 220 | Polycrystalline | 60 Full-Cell 156×156 mm | Monofacial | 600V System Voltage
Product Overview
The ATI 220 polycrystalline solar panel from Alps Technology Inc. delivers a reliable 220W output in a compact, durable format designed for residential, commercial, and light industrial projects. With its 60 full-size 156×156 mm polycrystalline cells and module efficiency of 13.5%, this 220W solar panel converts sunlight into dependable power while keeping system design simple and cost effective. The module operates efficiently at a maximum power voltage of 29.2V and a current of 7.54A, making it suitable for 24V battery systems and a wide range of grid-tied inverters. A maximum system voltage rating of 600V supports flexible string configurations for small rooftop arrays and distributed installations. Robust mechanical engineering is evident in the tempered glass front, anodized aluminum frame, and EVA encapsulant, which work together to protect the cells from weather and mechanical stress over many years of outdoor use. With dimensions of 1632×995×50 mm and a weight of 24.3 kg, the ATI 220 panel balances power density and handling, making transport and installation straightforward for professional installers and informed DIY users alike. This panel is well suited for applications requiring a proven polycrystalline technology platform that offers stable performance across a broad operating temperature range from -40°C to 90°C.
Key Benefits
Balanced 220W power range: The ATI 220 module sits within a 210 to 230 Wp power band, giving designers flexibility while maintaining consistent performance across an array. This range supports optimized string sizing and helps ensure predictable output for small and medium systems.
Proven polycrystalline technology: Polycrystalline cell construction offers a dependable, field-tested platform with stable energy yield over time and attractive upfront pricing, making this module ideal where long-term reliability and value are equally important.
Durable mechanical design: Tempered glass, EVA encapsulation, and an anodized aluminum frame provide strong environmental protection, helping the panel withstand wind, snow, and handling stresses commonly encountered during rooftop and ground-mount installations.
Wide operating temperature range: An operating range from -40°C to 90°C enables deployment in cold climates, hot regions, and high-irradiance sites, while the 46±1°C nominal operating cell temperature supports steady output under typical field conditions.
Installer-friendly form factor: Standard 60-cell layout, manageable 24.3 kg weight, and integrated junction box with 900 mm cables simplify lifting, handling, and electrical connections, helping installers reduce time on the roof and improve project efficiency.
How It Works
The ATI 220 solar panel converts sunlight into usable DC electricity through an array of interconnected polycrystalline silicon cells. Each of the 60 cells absorbs photons from incoming light and releases electrons, creating an electrical current that flows through the panel’s busbars and output cables. Under standard test conditions, the module delivers 220 Wp of power at a voltage of 29.2V and a current of 7.54A at its maximum power point. This DC power is then routed to a charge controller for battery charging or to an inverter that converts it into AC electricity suitable for home and business loads. The panel’s open circuit voltage of 36.9V and short circuit current of 7.85A define the electrical limits used when designing safe and efficient strings. A 600V maximum system voltage rating allows multiple ATI 220 modules to be wired in series to reach the required voltage window for common inverter platforms. The encapsulated cell matrix, glass front, and rigid frame protect the cells from moisture, thermal cycling, and mechanical impacts, enabling long-term operation and consistent output across many years of service.
Photovoltaic energy conversion: Polycrystalline silicon cells absorb sunlight and free electrons inside the semiconductor material. Metal contacts collect these electrons and drive them into the external circuit, producing direct current that can be used immediately or stored in batteries.
Maximum power point operation: The ATI 220 panel operates most efficiently at 29.2V and 7.54A, where it reaches 220W output. Modern charge controllers and inverters track this maximum power point dynamically, adjusting operating voltage to extract the highest possible energy throughout the day.
System integration and safety: Multiple modules can be wired in series and parallel within the 600V system limit to match inverter or controller requirements. A 15A series fuse rating supports coordinated overcurrent protection, while robust insulation and junction box design help maintain electrical safety in varied installation environments.
