RS-M220 220W Solar Panel — Reliable, Lightweight Power
Overview
The RS-M220 is a compact, 220W solar panel designed for mobile and off-grid use as well as on-grid installations. It combines a 16-busbar cell layout, lightweight anodized aluminum frame and high-transmission AR tempered glass to deliver steady performance in low light and harsh environments while remaining easy to install and handle.
Benefits
- Consistent energy when you need it — better low-light output for cloudy mornings and evenings.
- Less hassle during installation — lightweight panel with pre-drilled holes speeds mounting and handling.
- Flexible system design — quick-connect cables allow series or parallel connections for different setups.
- Peace of mind — long 25-year output warranty and robust quality control reduce maintenance and replacement concerns.
- Reliable in tough conditions — certified to withstand strong wind, heavy snow and hail so your system stays online.
Features
- 16-busbar solar cell configuration for improved current collection.
- Lightweight anodized aluminum frame for corrosion resistance and easier handling.
- High-transmission, anti-reflective (AR) coated tempered glass for better light capture and durability.
- IP67-rated waterproof junction box with built-in bypass diodes.
- IP67-rated waterproof solar connectors and 3 ft panel leads (pair) included.
- Plug-and-play junction box and industry-standard quick-connect cables that work in series or parallel.
- Proven low-light performance for use on cloudy days, mornings and evenings.
- Stringent in-house quality testing (30+ tests including UV, thermal cycling, humidity freeze, etc.), PID resistance and 100% EL double inspection.
- Certified mechanical durability: 2400 Pa wind load, 5400 Pa snow load, and hail resistance (35 mm at 97 km/h).
- Pre-drilled mounting holes compatible with ground mounts, Z brackets, pole mounts and tilt mounts.
- Compatible with both on-grid and off-grid inverter systems.
