Please note that there may be a 1-3cm (0.4-1.18”) discrepancy due to manual measurement and slight color differences based on display settings. Additionally, the item's color might vary slightly from the images due to lighting and screen differences. We appreciate your understanding. Important: The solar panel supplies 5-18V DC power suitable for DC devices. The 5V USB port can be utilized for mobile phones, MP3 players, security cameras, solar street lights, fans, and other devices with a 5V USB connection.

The 18V DC port is suitable for devices operating between 12-18V DC, primarily for charging 12V lead-acid batteries, but it needs to be linked to the solar controller.

2. Solar panels are unable to supply electricity for home devices like rice cookers, TVs, and washing machines, as these require 110V/220V AC power. 3. By connecting several solar panels in parallel, more energy can be generated. However, a single solar panel can fulfill most requirements, including ventilation for doghouses, lighting for storage areas, oxygenation for fish tank water pumps, garden fountains, mobile phone charging, and charging 12V lead-acid batteries, among others.

Various factors such as lighting, angle, temperature, wire thickness, and length, as well as their proper usage, can affect power output. It is advisable to choose the solar panel based on its dimensions, design, and type of interface.
