How to Use

  • Install 1–6 compatible 18650 batteries in the internal battery bay, following the correct polarity and using cells with similar capacity.
  • Mount the 8W solar panel with the fixed bracket and angle it toward the sun to improve solar generation.
  • Connect your 5V–12V device to the 5.5 × 2.1 mm DC output and select a suitable voltage (5V/6V/9V/12V) on your system if needed.
  • Allow the panel to charge the battery pack in strong sunlight; a typical pack reaches full charge in about 8–12 hours.
  • When sunlight is limited, charge the battery pack with a suitable 5V adapter through the Micro USB input within the specified voltage range.

Who It’s For

This 8W solar panel is ideal for DIY makers, hobbyists and anyone building small off-grid projects that need a reliable 5–12V power source. It works well for garden sensors, mini IoT prototypes, experimental electronics and other low-power applications where running mains power is inconvenient.

Care & Maintenance

  • Keep the solar surface clean and free from dust, leaves or shading to maintain efficiency.
  • Use only quality 18650 cells and avoid mixing old and new batteries in the same pack.
  • Try to match batteries with similar capacity and internal resistance for balanced charging and discharging.
  • Check that seals and covers are properly closed for outdoor installations.
  • If you will not use the system for an extended period, disconnect loads and store it in a dry place.

Buyer questions

Do 18650 batteries come included?

No — batteries are not included. The internal bay takes one to six 18650 lithium cells in parallel, supports cells up to about 3300 mAh each (up to about 19800 mAh for a full six-cell pack), and starts from as few as one cell. Use cells with similar capacity and internal resistance for balanced charging and discharging.

What can the output run?

A 5.5 × 2.1 mm DC output with selectable 5V / 6V / 9V / 12V, rated 5V 2A, 6V 1.5A, 9V 1.2A and 12V 1A. That covers small electronics, DIY power setups, sensors and other low-voltage outdoor applications — garden sensors, mini IoT prototypes and experimental electronics.

Can I charge it without sun?

Yes — charge the battery pack with a suitable 5V adapter through the Micro USB input, within the specified 4.5V–5.5V charging range. Under strong sunlight, a typical pack reaches full charge in about 8–12 hours.

Can it stay outdoors year-round?

The unit is IP66 with working humidity up to 90% RH. Keep the solar surface clean and free from dust, leaves or shading, check that seals and covers are closed, and for extended storage disconnect loads and store it dry.
