HUIYEETEX Solar Charging Panel for Roller Blind Motors — 5V 5W USB 2.0, SunPower Cells, Slim 40×8cm

HUIYEETEX 5V 5W solar charging panel is a slim trickle-charger built to top up the batteries of USB-charged motorized roller blinds using indoor window sunlight.

This compact solar panel is made with high-efficiency SunPower monocrystalline cells and a USB 2.0 output to provide low-current maintenance charging for battery-powered shades. It’s designed to sit on or near a window frame, using natural light to reduce how often you must plug your blind motor into a wall charger. Because it’s intended as a supplemental, slow-charge source, actual performance depends on direct sunlight, window orientation and shade power consumption.

How will this panel affect my blind motor’s runtime?

When placed where it receives steady direct sunlight, the 5W panel can trickle-charge the blind motor’s battery and slow the rate at which the stored energy is depleted. It won’t quickly restore a fully depleted battery but can meaningfully extend intervals between manual charges for low-power motors.

• Rated 5V, 5W output suitable for low-power USB-charged motors
• SunPower monocrystalline cells with >22% conversion for efficient daytime trickle charging
• Best performance with consistent direct sunlight; reduced output in shaded or low-light conditions
• Intended to supplement, not replace, standard USB charging

Will this panel fit my window and how is it mounted?

The panel measures 40 x 8 cm (15.7 x 3.1 in), a slim profile that suits most sills and narrow frames without intruding on space. It ships with pre-applied adhesive tape for quick, damage-free installation, though you should confirm surface compatibility and measurements before mounting.

• Compact 40 x 8 cm size for small sills and narrow frames
• Pre-applied adhesive tape for tool-free mounting
• Clean, flat surfaces recommended to ensure adhesion and contact with sunlight
• Remove and reposition carefully to avoid adhesive residue or surface damage

What cables and connections are required to use it?

The HUIYEETEX panel provides a USB 2.0 output at 5V, so you’ll need a compatible USB charging cable for your motor. The package includes the panel and adhesive tape only, so verify your motor’s charging port and have the matching cable ready—Type-C is commonly used in modern blind motors.

• USB 2.0 5V output compatible with USB-chargeable blind motors
• No charging cable included—use the motor’s supplied cable or HUIYEETEX 5V Type-C cable
• Ensure motor supports trickle/maintenance charging via USB input
• Charging speed varies with sunlight and motor draw—expect slow, steady top-ups

How reliable and supported is this product?

Each panel undergoes a basic functionality test before shipping to ensure it meets performance expectations out of the box. If you experience issues, HUIYEETEX customer support will help troubleshoot or advise next steps when you provide your order details.

• Pre-shipment quality checks for basic electrical function
• Manufacturer support available for installation and performance questions
• Clear usage notes included: check compatibility and prepare a charging cable
• Designed as a low-power maintenance charger, not a fast-charge solution

Who is this for? The HUIYEETEX 5V 5W solar charging panel is aimed at homeowners and installers who want a low-profile, eco-friendly way to reduce manual charging of motorized roller blinds. It’s ideal for battery-powered shade systems with USB charging ports that receive reliable direct sunlight—particularly north- or south-facing windows in bright rooms. If you need fast recharging for high-drain motors or have very dim window exposures, consider a higher-wattage or direct-wired charging alternative.
