Thank you for choosing this product.
This 50W solar panel is highly ecient, lightweight and versatile.
The operation guidance aims to give you a look at how this product could be used. More
research is always recommended so that you can create your own solar power system that
exactly meets your needs.
Operation Guidance:
Step 1: Select a site to mount the solar panel. It is advised to install solar panel in a shade-
free location that has sunlight most of the day.
Step 2: Mount and secure the panel. There are many ways to do this but what is most
important is to ensure that sunlight to the solar cells is not blocked. The simplest way is to
fix panel with hooks or rope via the pre-drilled mounting holes.
Step 3: Set up your solar panel system and connect everything. The picture below provides
one example.

Tips:
1. It is NOT recommended to connect more than 6 solar panels in series or in parallel.
2. We have tested that the panel can be safely curved up to 30 degrees’ maximum. Please
handle the solar panel with care and avoid over-bending it on a bumpy surface, as this
may result in damage to the product.
3. Loss of eciency (over time) is not considered a defect. It is considered normal for the
eciency of solar panel to degrade a small amount every year. External factors such
as local solar intensity, shading, soiling, snow and ambient temperature all could also
influence the performance of the panel.
Warning:
1. This module produces electricity when exposed to light. Please follow all applicable
electrical safety precautions.
2. Only qualified personnel should install or perform maintenance work on these modules.
3. Be aware that dangerously high DC voltages can occur when connecting multiple
modules in series.
4. Do not damage or scratch the rear surface of the module.
