Key Features & Benefits
Complete, Ready-to-Install Kit: All components are included to build a functional solar charging system — no need to source parts separately or guess about compatibility.
High-Efficiency 20W 24V Solar Panel: Delivers reliable 24V DC power with 21.2% module efficiency using 60 monocrystalline cells (6x10 matrix). The compact 15.94" × 14.17" footprint weighing only 4.13 lbs makes it ideal for space-constrained 24V installations.
3A 24V PWM Charge Controller: The Eco Energy S3 24V features 3-stage PWM charging (bulk, absorption, float), very low 0.6 mA battery consumption, automatic night-time shutdown, temperature compensation, and is fully encapsulated in epoxy potting for maximum weather protection. Designed and built in North America. Backed by a 5-year warranty.
Heavy-Duty L-Style Mounting Bracket: The SLB-0120 aluminum bracket securely mounts the solar panel to a wall, fence, flat surface, or pole (U-bolts sold separately), with a fixed angle for simplified installation.
Pre-Cut 18-2 Tray Cable (10 ft): 18AWG copper wire is rated for approximately 7-10 amps — more than sufficient for the 20W panel's 0.59A current. Red and black color-coded conductors eliminate polarity confusion, and the sunlight-resistant UV-rated jacket prevents cracking and degradation.
Outstanding Low-Light Performance: The monocrystalline solar panel generates power even during dawn, dusk, and overcast conditions, maximizing daily energy harvest.
Durable & Weather-Resistant Construction: The solar panel features a sturdy 30mm anodized aluminum frame and thick back plate. The charge controller is fully epoxy-potted. The cable is UV-resistant. All components are built to withstand harsh environmental conditions including extreme temperatures (-40°C to +50°C / -40°F to 120°F).
Eco-Friendly Manufacturing: The Eco Energy S3 charge controller is built using solar power for a truly sustainable solution, with North American design and craftsmanship.
Strong Warranty Coverage: Solar panel backed by 5-year product, 10-year 90% power, and 25-year 80% power warranty. Charge controller includes 5-year warranty. Mounting bracket includes 2-year warranty.
