DOES THE 200W SOLAR PANEL GENERATE A FULL 200W OF POWER?
In most cases, it is normal for a solar panel not to deliver its full nominal power.
Some of the reasons why this happens, as well as some suggestions for getting
closer to the nominal power figure, are given below:
a: Light Intensity
b: Surface Temperature
c: Sunlight Angle
d: Panel Shading
e: The length of the cable
f: The input limitation of Power Stations
HOW MUCH POWER CAN THE 200W SOLAR PANEL GENERATE UNDER
NORMAL CONDITIONS?
This depends first and foremost on weather conditions. Generally speaking, on
a clear day with no clouds in the sky, sunlight hitting the panel at a 90° angle
usually generates 90W–150W of power in the 200W panel.
WHAT IS THE METHOD OF CLEANING THE SURFACE OF SOLAR PANELS?
Remove dirt and dust from the surface firstwith a soft brush, then with a damp
cloth. To prevent performance degradation, keep the surface of the solar panel
clean.
IS IT WATERPROOF?
Yes, the solar panel meets IP65 waterproof. In order to maximize the lifespan of
the solar panel, please try not to get it wet or soak the solar panel into water.
