Although a solar system has several advantages and application scenarios, it also has some limitations. Here are some situations where a solar system cannot or is not suitable:

Cloudy days or nights: Because solar systems rely on sunlight to generate electricity, solar power production drops significantly on cloudy days or at night, which can lead to blackouts if there is no storage or other alternative sources of energy.

High-latitude areas: The sunshine time in high-latitude areas is relatively short, and the effect of solar power generation is not as good as that in low-latitude areas, and the sunshine time in winter is shorter, so the actual effect of applying solar energy systems in high-latitude areas will be limited.

Shading by trees or buildings: If the solar panel is shaded by objects such as trees or buildings, it will reduce the efficiency of solar energy collection.

Available area limitation: solar systems require a certain installation area. If the area is limited, it will be more difficult to collect enough solar power. At the same time, it is not easy to install solar systems in densely populated areas such as cities where space is tighter.

To sum up, solar energy systems cannot be applied to all environments and conditions, and it is necessary to select suitable areas and equipment, as well as auxiliary equipment with storage capacity, in order to better utilize the advantages of solar energy.
