The beginning of summer, the seventh of the 24 solar terms, usually arrives on May 5 or 6 every year, marking the official start of summer. At this time, the sun reaches the ecliptic longitude of 45°, the sunshine time in the northern hemisphere increases significantly, the temperature rises significantly, and everything enters the vigorous growth period.  1. Photovoltaic advantages in the beginning of summer Enhanced sunshine: After the beginning of summer, the solar radiation intensity in the northern hemisphere increased significantly, and the average daily power generation of photovoltaic modules increased by 15%-20% compared with spring.Suitable temperature: The temperature in early summer is moderate (20-30°C), close to the optimal working temperature of photovoltaic modules (25°C), and the efficiency is higher.Less rain and more sunshine: The rainy season has not yet arrived, reducing the blocking of modules by dust and rain, and reducing O&M costs.2. The energy-saving wisdom of photovoltaic agricultureThe beginning of summer is also the busy season for farming, and the "agriculture and photovoltaic complementation" model ushers in new opportunities:Photovoltaic summer planting: planting shade-loving crops (such as mushrooms and Chinese medicinal materials) under photovoltaic panels to achieve "power generation on the board and a bumper harvest under the board".Fishery and PV integration: When the water temperature rises in summer, the water surface photovoltaic can reduce water evaporation and provide a shading environment for fish and shrimp.3. O&M advice: Prepare for the middle of summerCleaning components: Take advantage of fine weather to clean dust and improve light transmittance.Check heat dissipation: Ensure that the inverter is ventilated to avoid high temperature and efficiency degradation.Lightning protection preparation: Thunderstorms increase in summer, and it is necessary to check whether the grounding system meets the standard.Conclusion: From the ancient times of "watching summer at the beginning of summer" to today's "photovoltaic summer", new energy is inheriting the wisdom of solar terms with science and technology. Grasp the light dividend and let every ray of sunlight be converted into green energy!
