Specification

How to Use

• Open the storage bag and take out the solar charge cable.

• Stand up and then unfold the solar panel.

• Unfold and then fix the support stands.

• Ensure that the solar panel is placed securely.

• Charge solar generators by using the solar charger cable.

• Charge other devices by using the charging expansion box.

Wiring Methods of Solar Panel

• When you need to use two or more solar panels simultaneously, there are two wiring methods you can choose from: Series and Parallel.

Series Connection

Parallel Connection

Placement of the Solar Panel

• For maximum solar energy efficiency, place the solar panel correctly so that it can receive sunlight at a 90° angle and keep it unshaded. Avoid shading from trees or objects, and ensure that the solar panel is fully deployed.

Angle Adjustment of Solar Panel

• The adjustable stands should be used before 10:00 am or after 2:00 pm. To use the solar panel during midday, simply place the solar panel flat on the ground.

• Place the A stand on the ground to achieve angles of 35° and 40°.

• Place the B stand on the ground to achieve a 45° angle.

Safety Instructions

Precautions for Use

1. During use, ensure that all components are in proper condition.
2. Do not immerse the solar panel or its connectors in water or liquids.
3. Prevent external shocks, drops, or pressure to avoid damage to the solar cells.
4. Ensure that the charging cable is plugged into the input port correctly, and the joint is dry and clean. Otherwise, sparks or poor circuit contact may occur.
5. Operate the equipment in dry weather conditions, and avoid using it in rainy or damp environments to prevent damage.
6. During use, avoid shading the solar panel with tree shadows, buildings, and any obstructions, because they can impact power generation efficiency.
7. Ensure there are no stones or objects underneath the solar panel when it is lying flat on the ground to avoid damage.
8. Only use the equipment for charging with a compatible solar generator to avoid performance or safety issues.
9. The direct current generated by the solar panel cannot be directly used for other devices. It is necessary to utilize the provided charging expansion box to charge other devices.
10. When charging the device, prevent short circuits between positive and negative terminals to avoid device damage or electrical shock hazards.
11. When connecting multiple solar panels in series, the voltage will increase, ensuring the total voltage does not exceed the safe voltage range. Please understand circuit principles before operating.
12. During use, it’s a normal situation that the solar panel would bend slightly for a while with an increase in temperature.

Maintenance and Care

1. Fold back to its original shape before storage.
2. Do not attempt to disassemble or scratch the panel.
3. Do not step on the solar panel or place heavy objects on it.
4. Prevent corrosive substances from damaging the solar panel cells.
5. Clean gently with a damp cloth, don’t rinse with water, avoiding abrasive materials.
6. Periodically inspect for damage such as cracks or scratches, and address any issues promptly.
7. Store it in a dry and secure place, away from direct sunlight, open flames, flammable materials and extreme conditions.

Disposal
In the United States, solar panel disposal falls under e-waste regulations. Please follow federal and state guidelines for proper disposal, locate local e-waste recycling centers for responsible disposal, and consider professional e-waste disposal services for compliance with regulations. Always prioritize recycling options over landfill disposal for electronic waste.

FAQ

Can a 100W solar panel generate its full nominal power of 100W?

• In most cases, it’s normal for a solar panel not to deliver its full nominal power. Some reasons contribute to this, and here are some suggestions for getting the full nominal power below:

Light Intensity

• The sunlight intensity on the solar panel will affect the power output fluctuation. Using the product under bright midday sunlight is more likely to yield full nominal power output similar to test conditions compared to morning or afternoon usage.

Weather Conditions

• Weather conditions impact sunlight exposure, such as foggy, cloudy, or rainy days. Full nominal power figures are less likely to be achieved during such conditions.

Surface Temperature

• The panel’s surface temperature affects electricity generation.
• Cooler panel surfaces generate more electricity. It’s normal for solar panels to generate more power during winter than in summer. Solar panels typically reach around 60°C (140°F) during operation, leading to a reduction in conversion efficiency as every industry standard.
• For instance, at 60°C (140°F) during summer, despite the higher light intensity, full nominal power can be reduced by 12%-15%, and the full nominal power can be attained only briefly.

Sun Angle

• For optimal performance, sunlight should ideally hit panels perpendicularly. A ±10 degree deviation from the 90° angle has minimal impact on panel power.

Panel Shading

• During use, the panel’s surface should remain unblocked. Shadows, foreign objects, and even glass can considerably diminish power output.

Under normal conditions, how much power can a 100W solar panel generate?

• This primarily hinges on weather conditions. In general, on a clear day with an unclouded sky, the prevailing sunlight intensity typically ranges from 800W to 900W/m (74.3W to 83.6W/ft). With a panel temperature of 50°C (122°F), when sunlight strikes the panel at a 90° angle, it typically generates between 70W and 90W of power.
• Nominal power ratings are established based on AM1.5 test conditions of 1000W/m (92.9W/ft) incident sunlight intensity, midday winter sun, and a panel temperature of 25°C (77°F). Power output figures that closely approach the nominal rating are typically observed.

Can it be connected in series with other brands of 100W panels?

• Yes, it’s possible to connect panels from different brands in series.
• However, it’s not recommended if there’s a significant difference in output current. Connecting panels with varying current output in series can limit the overall current output, preventing the full utilization of the 100W panel’s power, the combined effect might result in a situation where 1+1<2.
• If you intend to connect multiple panels in series, it’s advisable to use panels of the same specifications and sizes. Additionally, ensure that the voltage after the series connection remains within the limits supported by your equipment.

Can it be connected in parallel with other brands of 100W panels

• Yes, it can be connected in parallel with other brands of 100W panels, but cautious usage is advised. The parallel connection will double the total current of the input power. While you can parallel 100W solar panels, there is a risk that the combined current may exceed the equipment’s maximum allowable current.
• Please remember that only two 100W panels can be safely connected in parallel. If you intend to parallel more than two 100W panels, ensure that your equipment’s maximum allowable current supports the input current after parallel connection and that the parallel connection cables are capable of handling the maximum combined current after paralleling.
