SLD Tech ST-150Q-12Y 150W 12V Monocrystalline Solar Panel

Product Overview

The SLD Tech ST-150Q-12Y is a 150 W monocrystalline solar panel with a nominal 12 V DC output. Use it to charge 12 V battery banks through a suitably rated PWM or MPPT charge controller — typical for RV, marine, cabin, and other off-grid 12 V systems.

At 150 W with Vmpp ≈18.5 V, it delivers more current than smaller 50–100 W 12 V panels, so it suits medium off-grid loads when roof or rack space allows a ~45 × 28 in module.

Best For

• 12 V RV, marine, cabin, and portable off-grid battery charging
• Remote monitoring, lighting, and telecom sites on 12 V banks
• DIY and installer projects that need a documented 150 W / 12 V mono module

Compatibility / Important Considerations

• Size the charge controller for Impp/Isc and cold-weather Voc. Parallel panels for more current only within controller limits.
• Not Class I Division 2 rated — use SLD Tech CID2 models for hazardous locations.
• Professional or experienced DIY installation recommended; secure mounting and correct polarity are required for mobile (RV/marine) use.
