Description
Solartech M Series 20W 12V Solar Panel - SPM020P-DA compact, ultra slim power solution for small scale off grid applications, the SolarTech Power SPM020P D delivers 20W of reliable energy with a pre wired junction box. Featuring an ultra thin 0. 7" (18mm) frame and 9ft (2743mm) of 18AWG wire, this panel is ideal for battery maintenance, signage, remote sensors, and portable power needs where both space and profile height are limited. Key Features & Benefits Ultra Slim Profile (0. 7" 18mm): Features
A compact, ultra-slim power solution for small-scale off-grid applications, the SolarTech Power SPM020P-D delivers 20W of reliable energy with a pre-wired junction box. Featuring an ultra-thin 0.7" (18mm) frame and 9ft (2743mm) of 18AWG wire, this panel is ideal for battery maintenance, signage, remote sensors, and portable power needs where both space and profile height are limited.
Key Features & Benefits
Ultra-Slim Profile (0.7" / 18mm): Features an ultra-thin frame at just 0.7 inches, making it perfect for installations where low clearance, aesthetics, or minimal visual impact are critical.
Compact Footprint: Measures just 22.0" x 14.2", weighing only 5.5 lbs, ideal for space-constrained applications where larger panels won't fit.
Pre-Wired for Easy Installation: Includes 9 feet (2743mm) of UL-approved 18AWG cable factory-installed into a fully sealed junction box, eliminating the need for additional connectors or field wiring.
Weather & UV Resistant Junction Box: Fully sealed junction box constructed with UL1703-compliant materials, ensuring long-lasting outdoor durability against moisture, UV exposure, and environmental stress.
20W Power Output for Small Applications: Provides reliable power for 12V applications including battery maintenance, small pumps, signage lighting, remote sensors, gate openers, and portable electronics.
36-Cell Polycrystalline Design: Utilizes 36 narrow cells (156mm x 26mm) arranged in a 4x9 series matrix, delivering reliable 12V nominal power in a slim footprint.
UL Approved Cable: Features UL-approved 18 AWG cabling for compliance with safety standards and peace of mind.
No Bypass Diodes: Note that this panel does not include bypass diodes, making it best suited for unshaded, direct-sun installations (see note below).
Durable Construction: Built with high-transmission 3.2mm tempered glass, double-layer EVA encapsulation, and white polyester back cover with Tedlar for long-lasting outdoor performance.
600V System Compatibility: Maximum system voltage of 600V DC allows for flexible array configurations.
⚠️ Important Note: No Bypass Diodes
This panel (SPM020P-D) does not include Schottky bypass diodes. It is best suited for unshaded installations or single-panel applications. For shaded installations or series connections where shading may occur, consider the SPM020P-F or SPM020P-BP models which include bypass diodes.
