HOBO by Onset SOLAR-3W - Solar Panel Kit 3 Watts

The SOLAR‑3W kit by HOBO is a 3.0 Watt, 6 Volt solar panel designed to support outdoor data logging systems in challenging environments—think moderately cloudy regions, higher latitudes, or medium data-transfer needs. Ideal for rugged setup with HOBO data loggers, it ensures sustained monitoring without frequent battery replacements.

What’s Included

• 3 Watt solar panel with full assembly hardware (brackets, screws, bolts, lock washers)

• U-bolts, saddles, and flanged nuts to attach panel to a mast up to 1.63 in (4.1 cm) diameter 

• Step‑by‑step installation instructions/manual included

Specifications

Benefits & Use Cases

• Compact and lightweight—easily field-installed or repositioned for optimal sun exposure

• Compatible with HOBO USB weather stations, environmental loggers, and remote monitoring kits

• Durable hardware ensures stable mounting and long-term performance

Application Tips

• Mount in full sun for best output—shading significantly reduces performance 

• Commonly paired with U30‑series HOBO weather stations and environmental monitoring kits

• Use mast hardware provided to angle the panel optimally (bracket supports angles of 15°, 30°, 45°, 60°, 75°) 

Ideal For

• Environmental researchers, climatologists, and field scientists

• Agritech data monitoring (soil moisture, microclimate logging, crop observations)

• Remote weather station deployment and off‑grid sensor networks

• Anyone needing dependable, passive solar power for rugged instrumentation
