The energy efficiency rating of household solar water heaters in Jiangsu Province accurately reflects the current power-saving performance of solar water heaters in the province.
1. For consumers and engineering contractors, this data enables them to obtain a detailed understanding of the power-saving performance of a specific solar water heater model, facilitating consumers' analysis and selection of solar water heaters;
2. Standardization institutions such as industry associations and the Solar Energy Standardization Technical Committee can use this data to provide measured data and grading basis for formulating grading standards for the power-saving performance of solar water heaters;
3. It provides calculation basis for architectural design units and building energy assessment institutions to calculate the renewable energy savings of buildings during the architectural design process.

Algorithm Rules:
1. Data Source: The data is derived from the nominal water capacity, collector area, experimentally measured unit-area solar heat gain Qs(e) and heat loss coefficient Usl(e) labeled on solar water heater products.
2. Energy Efficiency Coefficient (CET) for Household Solar Water Heaters: CET = (Heat Gain - Heat Loss) / 3.6 / Collector Area.
Through analysis of the experimentally collected data, the value range of the household solar water heater energy efficiency coefficient CET is determined to be between 1.0 and 1.6, mainly concentrated between 1.3 and 1.5, with few data points exceeding 1.5. The grading standards are formulated as: Grade 1: CET ≥ 1.50; Grade 2: 1.50 > CET ≥ 1.3; Grade 3: 1.30 > CET ≥ 1.2; Grade 4: CET < 1.2
