Frequently Bought Together
Rich Solar MEGA 220 — 220 Watt 12V Solar Panel
The MEGA 220 is a 220-watt, 12-volt monocrystalline solar panel built for dependable off-grid power in compact installations. With a 16-busbar half-cut cell design, AR-coated tempered glass, and a robust anodized aluminum frame, it delivers reliable output for RV rooftops, boats, cabins, sheds, and DIY 12V battery charging systems — all backed by a 25-year output warranty and over 30 in-house quality tests.
220W Output in a Space-Efficient 12V Panel
At 55.1 × 30.0 × 1.2 inches and just 23.7 lbs, the MEGA 220 packs 220 watts into a manageable rooftop footprint — purpose-built for 12V battery systems in RVs, vans, trailers, and off-grid cabins.
Certified for All-Weather Performance
Engineered to handle 2400 Pa wind loads, 5400 Pa snow loads, and 35mm hail at 97 km/h. The IP67-rated junction box and waterproof MC4 connectors seal out moisture and dust for long-term outdoor reliability.
25-Year Output Warranty
Backed by a 25-year power output warranty and a 10-year workmanship warranty. Every panel passes 30+ in-house tests including UV exposure, thermal cycling, PID resistance, and 100% double EL imaging inspection.
Product Overview
The Rich Solar MEGA 220 is a 220-watt monocrystalline solar panel optimized for 12-volt off-grid systems. Operating at 18.3V maximum power voltage (Vmp) and 22.1V open circuit voltage (Voc), it fits naturally into 12V battery bank setups and pairs cleanly with standard PWM and MPPT charge controllers commonly used in RV, marine, and cabin applications.
The panel's 16-busbar half-cut cell layout reduces internal resistive losses and limits hot spot formation — two of the most common causes of long-term panel degradation. Bypass diodes built into the junction box help maintain stable output across the array when partial shading occurs from vents, antennas, or obstructions common on rooftop installs. Combined with AR-coated high-transmission tempered glass, the MEGA 220 delivers stronger low-light performance on overcast days, during morning and evening hours, and in partially shaded conditions.
At 23.7 lbs with pre-drilled mounting holes and 3-foot plug-and-play MC4 cables, the MEGA 220 is designed for straightforward solo installation across a range of common mounting systems including Z brackets, pole mounts, ground mounts, and tilt mounts.
Built to Last Outdoors
- IP67 Weatherproof Junction Box: Fully sealed against moisture and dust ingress — reliable in rain, condensation, and high-humidity environments.
- IP67 Waterproof MC4 Connectors: Industry-standard quick-connect solar connectors rated for direct water exposure.
- Wind & Snow Load Certified: Tested to withstand 2400 Pa wind and 5400 Pa snow loads for year-round rooftop installations.
- Hail Resistant: Validated against 35mm hail at 97 km/h — the same impact resistance standard used across the MEGA panel lineup.
- Anodized Aluminum Frame: Lightweight, corrosion-resistant frame provides structural rigidity and long-term protection against weathering and oxidation.
Smart Cell Design for Real-World Output
- 16-Busbar Half-Cut Cells: Splits each cell in two, reducing current per cell and lowering resistive losses — more of your available sunlight becomes usable power.
- AR-Coated High-Transmission Glass: Anti-reflective coating reduces surface reflection and improves light absorption across the full arc of the sun throughout the day.
- Excellent Low-Light Performance: Continues generating meaningful output on overcast days, during early morning hours, and in partially shaded conditions — reducing daily dead time in your charging cycle.
- Bypass Diodes: Built into the junction box to maintain stable array output under partial shading, preventing one shaded panel from pulling down the entire string.
- PID Resistant: Engineered to resist potential-induced degradation, protecting long-term output in higher-voltage string configurations.
30+ Quality Checkpoints Before Shipment
- 100% Double EL Inspection: Every panel is imaged using electroluminescence diagnostics to detect micro-cracks and cell defects invisible to the naked eye before leaving the factory.
- UV, Thermal Cycling & Humidity Testing: Panels are validated through real-world stress simulations including UV exposure, high-humidity freeze-thaw cycles, and thermal shock.
- PID Resistance Testing: Protects against gradual efficiency losses in high-voltage off-grid and grid-tie applications over the panel's service life.
- 25-Year Output Warranty: Linear output warranty backed by Rich Solar's U.S.-based customer support team, reachable by phone and email.
- 10-Year Workmanship Warranty: Covers manufacturing defects in materials and construction separate from power output degradation.
Easy Installation Across Any Mount Type
- Pre-Drilled Mounting Holes: Compatible with Z brackets, pole mounts, ground mounts, and tilt mounts — no additional drilling required for most standard mounting hardware.
- Plug-and-Play MC4 Cables: 3-foot pre-attached leads with industry-standard MC4 connectors allow fast, tool-free connection to your charge controller or other panels.
- Series or Parallel Compatible: Wire multiple MEGA 220 panels in series to raise voltage for an MPPT controller, or in parallel to increase current for a PWM setup — flexible for a range of 12V and 24V system configurations.
- On-Grid & Off-Grid Inverter Compatible: Supports both standard off-grid inverter setups and grid-tie configurations with a 1500V maximum system voltage rating.
- Lightweight at 23.7 lbs: Manageable solo for most rooftop and ground-mount installations without specialized lifting equipment.
