Solar panels have a long lifespan, often reaching up to 30 years or more. Reputable companies typically adhere to high standards and provide warranties for solar panels that can extend up to 25 years.

The maintenance of solar panels and solar equipment often emphasizes keeping the control panel system in normal conditions and ensuring the cleanliness of the solar panels. Roofs with a significant slope, especially, aid in washing away dirt during rainfall, with less dust accumulation compared to roofs with a lower slope. However, there are still other factors such as oil stains in areas near factories that can affect electricity production. Maintaining the cleanliness of solar panels is crucial for optimal efficiency.

Neglecting solar equipment maintenance may lead to a slight reduction in electricity production, but often it does not have a significant impact. Prompt problem resolution and post-sales service speed are other factors that homeowners should consider to ensure optimal efficiency and the best user experience.
