Electricity generation, salt drying, and aquaculture are the three musts! The world's largest single unit capacity "salt solar complementary" power station is connected to the grid for power generation in Tianjin | Photovoltaic power station | Single unit
On July 8th, the world's largest single unit "salt light complementary" project - Huadian Tianjin Haijing 1 million kilowatt "salt light complementary" power station was connected to the grid for power generation. While enhancing the power supply guarantee capacity in North China, explore a composite industrial model of photovoltaic power generation, surface brine production, and underwater aquaculture.
CCTV reporter Gu Junling: This is the world's largest single unit capacity "salt light complementary" project - Huadian Haijing Photovoltaic Power Station, which has just been put into operation. It sets up photovoltaic modules on salt fields, ensuring three aspects: power generation, salt drying, and aquaculture.
The biggest difference from other photovoltaic power stations is that the spacing between the photovoltaic arrays here is much larger, reaching 14 meters, which is almost more than twice that of other photovoltaic power stations. The purpose of doing so is to minimize the obstruction of photovoltaic panels on the water surface and their impact on salt industry production.
The slope of this photovoltaic panel is precisely designed at 17 degrees, while most other photovoltaic power stations are around 30-40 degrees. This is because, based on the trajectory of the sun's movement throughout the year, 17 degrees provides the least obstruction to the water surface.
Moreover, the photovoltaic panels here can generate electricity on both sides. In addition to directly absorbing sunlight for energy conversion on the top, the back can also absorb sunlight reflected from the water surface. With this alone, its power generation efficiency can be improved by 5-7%.
Yang Fan, the person in charge of the Huadian Haijing Salt Light Complementary Project: After our project is put into operation, 1.5 billion kWh of green electricity will be produced annually from these 20000 acres of salt fields, which will further promote the transformation of the green energy structure in North China and drive the internal circulation of the regional industrial chain. At the same time, a new composite industrial model of "salt light complementarity" is achieved, which includes water-based photovoltaic power generation, surface evaporation for brine production, and underwater aquaculture.
