The above is the annual attenuation of solar panels, which will remain between 80% and 85% after 25 years.
This is the attenuation rate promised by LONGI battery cells, and there is a corresponding warranty document.
We will provide the linear attenuation guarantee of the product to ensure that the photoelectric conversion efficiency is not less than 80% within 25 years.
We can also provide high-quality performance guarantee and attenuation data to ensure LONGI brand first-class solar panel raw materials, ensure small attenuation and extend the service life of solar panels.
The King of the Democratic Republic of the Congo has provided a solar energy storage power station system for the village of Bunkeya to meet the electricity needs of 2500 small households in the village. As the village currently lacks access to the grid, the King requested the design of a 1MW solar panel system paired with a 1.8MWh lithium battery storage system to power the entire village.
