Installation

Unpack and inspect contents. Ensure all parts are present and undamaged.

  1. Choose Location: Select a site with maximum sunlight exposure, free from shading (trees, buildings).
  2. Mounting: Use included mounting brackets or compatible hardware. Secure panel to roof, ground mount, or pole using corrosion-resistant bolts.
  3. Orientation: Tilt panel toward the sun (angle varies by latitude and season).
  4. Wiring: Route cables from junction box to charge controller, keeping them protected and away from sharp edges.

WARNING! Do not install during inclement weather. Ensure mounting surface can support panel weight. Use proper personal protective equipment (PPE).

First-Time Setup

After mounting, connect to a solar charge controller and battery system.

  1. Connect Panel to Charge Controller: Use MC4 connectors to link panel's positive (+) and negative (-) leads to corresponding inputs on charge controller.
  2. Connect Charge Controller to Battery: Follow controller manual to connect to 12V battery (ensure correct polarity).
  3. Verify Operation: Check charge controller display for incoming voltage (should be ~18V open circuit in full sun).
  4. System Check: Ensure all connections are tight and weatherproof.

CAUTION! Never connect panel directly to battery without a charge controller. Risk of overcharging and damage.

Specifications

Controls and Connections

Panel has no active controls. Power management is handled by external charge controller.

Junction Box: Located on back of panel. Contains terminal block for positive (+) and negative (-) leads, sealed with MC4 connectors.

MC4 Connectors: Standard solar connectors. Male connector is positive (+), female is negative (-). Ensure proper mating and weatherproof seals.

Grounding: Use grounding lug (if provided) to connect frame to earth ground per local electrical codes.

Connecting to System

For 12V battery charging system with charge controller.

  1. Turn off all system components before connecting.
  2. Connect panel wires to charge controller "PV" or "Solar" inputs.
  3. Connect charge controller to battery (observe polarity).
  4. Connect load (inverter, lights) to charge controller load terminals or battery.
  5. Power on charge controller; verify input voltage from panel.

Tip: Use proper gauge wiring to minimize voltage drop. Protect wires with conduit where necessary.

Operation & Performance

Panel generates DC electricity when exposed to sunlight.

  1. Daily Operation: Panel works automatically. Output varies with sunlight intensity, angle, and temperature.
  2. Monitoring: Check charge controller for charging status, voltage, and current.
  3. Seasonal Adjustment: Adjust tilt angle seasonally for optimal performance.
  4. Snow/Ice: Clear snow accumulation gently to restore output.
  5. Shading: Avoid partial shading; it significantly reduces output.

WARNING! Do not attempt to disconnect under load. Do not touch terminals during operation.

Maintenance

Regular maintenance ensures long-term performance.

CAUTION! Do not use abrasive cleaners or high-pressure water. Disconnect panel before maintenance.
