Soft brooms and snow rakes provide a safe way to clear snow from solar panels. Brooms with non-bristled, foam edges remove layers of snow without scratching the glass. . Inspect the Area: Ensure no hazards like power lines or sharp objects are near the panels. Use the Right Tools: Utilize a soft brush or a foam-headed roof rake designed for solar panels to gently remove snow. . And when snow does become a problem, the easiest way to automatically remove snow on solar panels isn't a rake or a gadget; it's smart system design. Polycrystalline Panels: These are generally more durable but may have slightly lower efficiency. Regular removal prevents significant energy loss, as accumulated snow can block sunlight. Utilizing safe tools avoids damage to both the panels and surrounding structures.

Wind and solar energy potential show similar characteristics in most parts of China, especially in the northern and southern parts of China. A few regions exhibit complementary characteristics, including the southeastern coastal areas and northeastern regions.
By calculating the Kendall rank correlation coefficient between wind and solar energy in China, the study mapped the spatial distribution of wind-solar energy complementarity. Han et al. proposed a complementary evaluation framework for wind-solar-hydro multi-energy systems based on multi-criteria assessment and K-means clustering algorithms.
Given that wind and solar energy are distinct forms of energy within the same physical field and are typically developed simultaneously in clean energy bases, it is essential to comprehensively assess the variation patterns of complementarity metrics under different climate change scenarios.
The seasonal and monthly wind-solar complementarity of China can be quantified through the calculation of WPD and PV pot, as depicted in Fig. 9, Fig. 10. It should be noted that Fig. 9, Fig. 10 are based on Spearman's rank correlation coefficients of WPD and PV pot, which are determined by the classification standards in Table 3. Fig. 9.
