The reflected spectral energy distribution data of solar water heaters (vacuum collector tubes) by wavelength serves as benchmark computational data for calculating the reflected spectral transmittance of the surfaces of solar water heater vacuum tubes. It can be used to calculate the reflected light transmittance of materials for solar water heaters across any wavelength range (280–2500 nm).

1. For architectural design institutes: This data can be used to calculate the light intensity of different wavelength ranges of solar water heater reflected light entering buildings via adjacent structures, enabling the design of architectural optical environments.
2. For solar water heater manufacturers: They can use this data to calculate the light reflection performance of produced vacuum tubes across different wavelength ranges, obtain reflection and transmittance data, and guide product process optimization.
3. For environmental law enforcement agencies: They can use this data to calculate the transmittance level of reflected light entering the indoor spaces of entities affected by light pollution, which is caused by the reflective glass tube materials of solar water heaters installed on surrounding buildings, and evaluate the severity of light pollution impacts.

Algorithm Rules:
1. Data Source: The data is derived from the tested and calibrated wavelength-resolved energy distribution of the reflected spectra of ordinary tempered solar water heaters, measured using a spectrophotometer with a 1 nm wavelength step for the 280–1700 nm range and a 5 nm wavelength step for the 1700–2500 nm range.
2. The reflected light transmittance $
ho(b)$ of the solar water heater material is calculated as:
$$
ho(b) = frac{sum left[ W(i) cdot
ho(i)
ight]}{sum W(i)}$$
Where:
- $W(i)$: The radiant energy of sunlight reflected by the solar water heater at a single wavelength, and $W(i) = G(i) cdot F(i)$
- $G(i)$: The radiant energy of the solar spectrum at a single wavelength
- $F(i)$: The wavelength-specific reflectance of the solar water heater
- $
ho(i)$: The transmittance of a given material at a specific wavelength
- $sum left[ W(i) cdot
ho(i)
ight]$: The total reflected spectral transmittance energy of the solar water heater within the target calculation or measurement band
- $sum W(i)$: The total reflected solar energy of the solar water heater within the target calculation or measurement band
3. By testing the transmittance of arbitrary energy of the material at each wavelength and then performing calculations using this data, the reflected light transmittance of the material corresponding to the target band can be obtained.
