PVTIME – LONGi has supplied 50 MW of its
high-efficiency mono-crystalline solar modules to the 150MW “Wind-Solar
complementary” project, a combination of 100 MW wind and 50MW solar
plant in Xiaohaotu Town, Yulin City (Shaanxi Province). With investment by the
Shaanxi Energy Group, the project is jointly constructed by the China
Energy Engineering Group’s Northwest Electric Power Test Research Institute and
Hunan Power Construction.
The project is Shaanxi Energy Group’s first self-built power station to
integrate wind power and ground centralized photovoltaic power. According to
company estimates, the average annual power generation of the project can reach
68.27 million kWh, which can save about 22,000 tons of standard coal each year.
The project also incorporated the construction of a 2 MW experimental
power station, to test various brands and types of solar modules. When
comparing power generation data from the station, the performance of LONGi’s
mono-crystalline modules was found to be superior to that of other modules
Since the 50MW solar project was connected to the grid, the power
generation performance of LONGi modules has been stable for more than a year.
Data shows that LONGi mono-crystalline solar modules can generate 2% more power
than conventional modules, even with low winter temperatures and frequent snow.
In practical applications, low-light, low attenuation and stability of
solar modules will affect their ultimate power generation capacity. LONGi’s
mono-crystalline modules have passed various outdoor empirical tests and been
applied in many large-scale projects, displaying superior outdoor
anti-attenuation performance. Test results for outdoor natural ageing from the
China Building Material Test & Certification Group (hereinafter referred to
as "CTC") have demonstrated that LONGi mono-crystalline solar modules
have an average attenuation rate of 0.38% in the first year, 0.32% in the
second, and 0.36% in the third year, ranking first for all mono-crystalline
modules on each occasion.
The 150MW project in Yulin City has not only brought significant
eco-environmental benefits for the local area, but also greatly promoted the
development of the tourism industry. The successful application of LONGi's
high-efficiency mono-crystalline modules in this project has also played a
positive role in diversifying local energy construction and has effectively
promoted the construction and application of renewable energy in the Northwestern
part of Shaanxi Province.
