Yes. When used outdoors for a long time, solar panels are prone to accumulate dust and foreign objects on the surface, causing a certain degree of light occlusion and reducing the output of power generation. Frequent cleaning keeps the surface of the solar panel clean and free of obstructions, allowing for better solar panel power output.
Yes. Parallel connection can double the current and increase the power. You can refer to the requirements for solar controllers and energy storage devices to ensure that they support larger values of input current to better determine the number of parallel connected solar panels. Additionally, it is necessary to pay attention to select a wire with a suitable wire diameter for safe connection according to the change of the output current.
Yes, but it is not recommended. Different energy storage controllers have requirements and restrictions on the output of solar panels. When solar panels with different current values are used in series, they will be limited, resulting in the inability to release the output power and even the short-board effect of 1+1<2.
The solar panel is made of monocrystalline silicon wafer. During installation and use, please do not drop it on the ground with force, or use tools to hit the surface. Do not step on or sit on the solar panel, so as not to cause the monocrystalline silicon wafer to break and affect its use. Artificial damages will void the warranty.
Please refer to the content in How to Choose the Installation Environment in this manual.
