Sunshine simulation: replicating natural light to drive innovation in photovoltaic and material research and development
Date: 2025-12-09Read: 1
Simulating a stable natural sunlight environment is a core requirement for experiments and production in fields such as photovoltaic module testing, material weather resistance research, and agricultural photobiology.sunlight simulationAs an "artificial sun", the device has become a key equipment for promoting the development of related industries due to its precise replication ability of solar spectrum and irradiation intensity. Numei (Tianjin) Technology Co., Ltd. has been deeply involved in the field of optoelectronic instruments for many years. The independently developed Sunshine Simulator, with its three core advantages of "high matching, high stability, and high intelligence," provides global users with a full field lighting solution from laboratory research and development to industrial quality inspection, becoming an important product trusted by the industry.
Spectral and irradiance matching is the core competitiveness of solar simulators and also the technological breakthrough point of Numei Technology. Traditional equipment often suffers from spectral shift and uneven irradiation, resulting in significant deviations between test data and actual outdoor environments. The Numei Sunshine Simulator is equipped with an imported multi band LED light source group and a self-developed spectral correction system, which can accurately reproduce the AM1.5G standard solar spectrum, with a coincidence rate of over 98% with natural sunlight in the wavelength range of 300nm-1200nm. Its irradiation intensity can be continuously adjusted within the range of 50-1200W/㎡, with uniformity controlled within ± 2%, meeting the strict requirements of international standards such as IEC61215 for photovoltaic module testing.
Long term stable operation is the fundamental guarantee for industrial quality inspection and scientific research experiments. Numei Technology has built a stable system throughout the entire chain from hardware architecture to software control: the light source module adopts a constant temperature heat dissipation design, combined with an intelligent temperature control system, to ensure that the temperature fluctuation of the light source does not exceed ± 0.5 ℃, effectively avoiding radiation drift caused by light decay; The core driving circuit adopts high-precision constant current technology, with a current stability of 0.01%, ensuring that the long-term fluctuation of irradiation intensity is less than ± 1%.
The wide adaptability allows devices to cope with diverse scene demands with ease. The Numei Sunshine Simulator can be customized with irradiation surface sizes ranging from 100mm × 100mm to 1000mm × 1000mm according to requirements, suitable for testing needs from small photovoltaic cells to large components; After being equipped with humidity control accessories (20% -90% RH) and temperature regulation modules (-40 ℃ -85 ℃), comprehensive testing can be achieved in a temperature humidity coupled environment, meeting the research needs of material weather resistance. For the rapid detection scenario of production lines, its automated transmission system can achieve continuous sample testing, increasing the efficiency of single sample testing by 50%. Currently, it has been widely used in photovoltaic module power testing, automotive interior light aging resistance experiments, plant photosynthesis research and other fields.
From improving the efficiency of the photovoltaic industry to breakthroughs in the performance of new materials, the Numei Technology Sunshine Simulator has become a core support for researchers and enterprises with its precise, stable, and efficient performance. Numei Technology has always adhered to the concept of "replicating nature and empowering innovation", continuously promoting the iteration of solar simulation technology, and helping the fields of photovoltaics, materials, agriculture, etc. achieve higher quality development.
