Set of 2 EcoFlow 400W Solar Panels (Rigid) + Mounting

What is the difference between serial and parallel connection? Why is it important to know?

Parallel connections move from positive to positive and from negative to negative poles. Series connections from positive to negative.

Parallel connections maintain the same voltage when summing current between panels. Serial connections do the opposite; they store voltage and maintain current.

Parallel connections still keep your array working even if one panel or connection doesn’t work properly. One damaged or defective part affects the entire array when connected in series.

Parallel connections are not recommended for high power panels as they can overload the power plant.

How to care for solar panels in winter?

How does snow affect the efficiency of solar panels?

When snow completely covers a solar panel, its cells cannot receive enough sunlight to store energy. The longer the surface of the panel is covered with snow, the less electricity will be generated. When installing the panels, choose an angle so that the snow can roll off the smooth surface on its own, and clean the panels regularly by hand.

Can solar panels continue to generate electricity while covered in snow?

If the panels are partially covered with snow, they continue to work. Even if the surface of the panel is completely covered with light snow, there is still a chance that the sun’s rays will reach the cells. However, it should be understood: the cleaner the surface of the panel, the more electricity it will produce.

Is it necessary to remove snow from solar panels?

If you set the panels at an angle, you may not need to remove the snow by hand at all. But if the panel will be under snow for a long time, you will need to clean its surface with a soft brush. A snow-cleared panel will better capture sunlight and generate electricity.

How can snow be prevented from sticking to the surface of a solar panel?

You must install the solar panel at a vertical angle so that the snow can slide down the smooth surface without lingering on it. Also regularly inspect the surface of the panel for various cracks and chips. Do not wait until the snow cover on the panel is too deep and heavy: its weight can damage the panel.

How does the amount of snow affect the operation of the solar panel?

The more area of the panel will be covered with snow, the less efficient the panel will work. Its functioning is also affected by the weight of the snow. Regularly inspect and clean your solar panels of snow and dirt to keep them working at their best.
