Key Features

A rugged, safety-certified power solution for hazardous locations, the SolarTech Power SPM020P-F delivers 20W of reliable energy with a Class 1 Division 2 (C1D2) Group C and D rating. Designed for use in environments where flammable gases, vapors, or liquids may be present, this panel is ideal for industrial monitoring, remote instrumentation, valve actuation, and safety equipment in refineries, chemical plants, and processing facilities.

Key Features & Benefits

Hazardous Location Certified: Class 1 Division 2 (C1D2) Groups C and D rating allows safe installation in areas where flammable gases or vapors (such as ethylene, propane, and similar hydrocarbons) may be present under abnormal conditions.

20W Power Output for Larger Loads: Provides double the power of the 10W model, perfect for 12V applications such as remote telemetry units (RTUs), valve actuators, tank level monitors, gas detectors, and backup power for safety systems.

Tool-Accessible Terminal Block: Features a junction box with terminals accepting 8-14 AWG wire, allowing for field wiring without special connectors and simplifying installation in industrial settings.

36-Cell Polycrystalline Design: Utilizes 36 narrow cells (156mm x 26mm) arranged in a 2x18 series matrix, delivering reliable 12V nominal power in a 21.7" x 13.8" footprint.

Durable Construction: Built with high-transmission 3.2mm tempered glass, double-layer EVA encapsulation, white polyester back cover with Tedlar, and an anodized aluminum frame for long-lasting outdoor industrial performance.

Schottky Bypass Diodes: Integrated bypass diodes minimize power loss from partial shading, ensuring consistent performance in real-world industrial environments.

600V System Compatibility: Maximum system voltage of 600V DC allows for flexible array configurations in smaller industrial systems.

Weather-Resistant Junction Box: IP65-rated junction box constructed with UL94-5VA flame-retardant material for enhanced safety and durability in outdoor industrial conditions.

Great replacement kit
Called around for quotes to get them replaced and everyone was quoting over $2k just for bellows. Figured I’d give it a try. The rubber is good quality and feels soft. Time will tell but this is an easy job if you’re mechanically inclined. Make sure you replace the plastic water pickup fitting while you’re at it. Found mine to be cracked on disassembly and had to wait for a new one. Should be a easy 3-4 hour job if your not doing the bearing and only doing bellows
