Observe whether the surface of the battery is clean, remove dust and dirt in time, and rinse with clean water or. Use clean. Do not wipe, but do not use chemical cleaning products to check if the array is wireless. If it falls, etc., pay attention to the appearance of all equipment against corrosion. In case of damage, etc., touch the device case with the back of your hand to check if there is temperature. Abnormally check leaking wires for insulation aging, mechanical damage, and water entering the box.
If photovoltaic power generation panels are not cleaned for a long time because dirt blocks the sun, it will only affect the efficiency of power generation and will not have virtually no impact on lifespan. The impact on service life is that long-term ultraviolet rays age components, ce which results in a photovoltaic conversion. The efficiency decreases from year to year and the attenuation index of the component is a very important parameter.
