Method and apparatus for detecting impairment of a solar array
View Patent ↗An apparatus for detecting an impairment of a solar array. The apparatus comprises an impairment detection module for performing a comparison of a power production profile and at least one reference profile, wherein the power production profile and the at least one reference profile are for at least one of the solar array, at least one solar subarray of the solar array, or at least one solar panel of the solar array. The apparatus determines, based on the comparison, whether the impairment exists.
1. An apparatus for detecting an impairment of a solar array, comprising:
an impairment detection module for performing a comparison of a power production profile and at least one reference profile and determining, based on the comparison, whether the impairment exists, wherein the power production profile and the at least one reference profile each correspond to a same at least one of the solar array, at least one solar subarray of the solar array, or at least one solar panel of the solar array, and wherein the power production profile and the at least one reference profile are graphical profiles that depict power production over time, and
wherein the impairment detection module automatically corrects the impairment upon determining that the impairment exists.
2. The apparatus of claim 1 , wherein an automatic correction comprises adjusting a Maximum Power Point (MPP) of the at least one solar panel to optimize power production of the at least one solar panel.
3. A method for detecting an impairment of a solar array, at least a portion of the method being performed by a computing system comprising at least one processor, the method comprising:
comparing, by the computing system, a power production profile to at least one reference profile, wherein the power production profile and the at least one reference profile each correspond to a same at least one of the solar array, at least one solar subarray of the solar array, or at least one solar panel of the solar array, and wherein the power production profile and the at least one reference profile are graphical profiles that depict power production over time; and
determining, by the computing system and from a result of the comparing, whether the impairment exists, wherein a reference profile of the at least one reference profile is generated by:
obtaining operating data over a predetermined period of time for the at least one of the solar array, at least one solar subarray, or at least one solar panel; and
processing the operating data to obtain the reference profile, wherein the operating data comprises at least one of an average power production or a usual power production over a specified period of time.
4. A method for detecting an impairment of a solar array, at least a portion of the method being performed by a computing system comprising at least one processor, the method comprising:
comparing, by the computing system, a power production profile to at least one reference profile, wherein the power production profile and the at least one reference profile each correspond to a same at least one of the solar array, at least one solar subarray of the solar array, or at least one solar panel of the solar array, and wherein the power production profile and the at least one reference profile are graphical profiles that depict power production over time;
determining, by the computing system and from a result of the comparing, whether the impairment exists; and analyzing, upon determining that the impairment exists, the power production profile to identify a cause of the impairment.
5. A method for detecting an impairment of a solar array, at least a portion of the method being performed by a computing system comprising at least one processor, the method comprising:
comparing, by the computing system, a power production profile to at least one reference profile, wherein the power production profile and the at least one reference profile each correspond to a same at least one of the solar array, at least one solar subarray of the solar array, or at least one solar panel of the solar array, and wherein the power production profile and the at least one reference profile are graphical profiles that depict power production over time;
determining, by the computing system and from a result of the comparing, whether the impairment exists; and automatically correcting the impairment upon determining that the impairment exists.
6. The method of claim 5 , wherein the automatically correcting comprises adjusting a Maximum Power Point (MPP) of the at least one solar panel to optimize power production of the at least one solar panel.
