| Use advice for data set | Users of this data should adhere to methodological guidelines that ensure the inclusion of all relevant processes in the lifecycle assessment of multi-Si PV cell production. Special attention should be paid to system boundaries, assumptions regarding the functional unit of 1 kWp of multi-Si PV cell production, the integration of direct emissions, and waste management practices. Users must also be mindful that this data is region-specific to Zhejiang Province and reflects the year 2010, which may require adjustment for other regions or temporal scenarios. |
| Technical purpose of product or process | The technical usage of the multi-Si PV cell production data set is to understand and apply the environmental implications of manufacturing multicrystalline silicon photovoltaic cells, which are often used in solar panels for converting sunlight into electricity. These cells, with an efficiency rated at 12.7%, are pertinent to solar power installations where economy and moderate efficiency are important considerations. |
