The system (100) can take a first irradiance measurement of the sun (S), the first irradiance measurement representing a direct solar irradiance. The system (100) can take a second irradiance measurement that represents an irradiance from a reflection of the sun (S) from the mirror target plus background irradiance from a reflection of the sky from the mirror target. The system (100) can take a third irradiance measurement that represents the background irradiance from the reflection of the sky from the mirror target. The system (100) can determine a reflectance of the mirror target from the first, second, and third irradiance measurements. The system (100) can compare the reflectance to a specified reflectance threshold, and, upon determining that the reflectance of the mirror target is less than the specified reflectance threshold, can generate an alert signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Monitoring mirror reflectance using solar illumination","description":"A system (100) and method can monitor a reflectance of a mirror target that includes at least one curved mirror (M).
