Solar panel QL15-5V 15.5W 5V/3A with wall mount

Product detailed description

The QL15-5V Monocrystalline Solar Panel with 15.5 W output serves as a permanent power source for outdoor devices without access to the mains – trail cameras, IP cameras, weather stations, IoT sensors, or Meshtastic nodes and ESP32 boards with battery charging. The panel is equipped with M12 monocrystalline silicon cells with 23.7% efficiency and full busbar interconnection, delivering 60–90 Wh on a sunny day and 12–20 Wh even under overcast skies. The 1.6 m cable is terminated with a USB-C connector, allowing you to connect powered devices without soldering or additional adapters. Included is an adjustable bracket for wall or pole mounting, allowing you to easily orient the panel south at the optimal angle.

Package contents:

• 1× QL15-5V Solar Panel - 15.5W, with articulated mount and USB-C cable

Note:

• The panel does not include a voltage regulator, charging circuit, or battery. The open-circuit voltage reaches 7 V, which is more than the rated 5 V – connect it only to a device with its own input regulation or via a solar charging module.
• The USB-C connector is used only to provide voltage to the VBUS and GND pins – the panel does not communicate via USB Power Delivery, so it may not work with devices requiring PD.
• Direct the panel south; otherwise, the charging capacity will decrease significantly.
• The panel must not be shaded during the day – even partial shade significantly reduces power output.
• Mount the panel so that the back side with the outlet cover faces downwards, never upwards towards the sky.
• The stated daily energy yields apply to the summer period with optimal orientation; expect significantly lower values in winter.
• When extending the cable, do not exceed a length of 10 m and observe the polarity (red = +, black = −).
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
