The price of a 200 watt solar panel is about 6,000 yuan/piece.
The model does not matter, the owner can use solar battery units to combine them according to his own needs.
In fact, there is no way to determine a model based on the power requirements indicated by the poster.
Just as the poster needs to use a battery to power an electrical device with a power consumption of 10 watts, the range of options is wide and almost any commercially available battery can be used.
