Abstract: A process for maximum power point tracking of a photovoltaic module, which includes monitoring the module's degradation by: for a periodicity n1δt0 with n1>1 constant or variable, steps of measuring parameters I and V of the module for points offset in voltage voltage VMPP+α and VMPP−β over the curve I(V) relative to the maximum power point MPP, calculating the slope dI/dV+ at the point VMPP+α and the slope dI/dV− at the point and VMPP−β and recording of the data with the MPP; for a periodicity n2δt0 with n2≥n1 of > of steps of measuring values I and V by sweeping the curve I(V) and calculating and storing the module's parameters and values; one or several steps of calculating, tracing and displaying of (p/2)
curves of data pairs based on p measured and calculated parameters; and one or more steps of detecting degradation from the measured and calculated parameters.

Abstract: It is hereby proposed a computer-implemented method of machine-learning a plurality of predictive basin-wise models. Each predictive basin-wise model is configured for predicting a concentration of an element at a given location in a saline aquifer of a respective basin. The machine-learning method comprises, for each basin and with respect to a predetermined set of one or more geochemical variables, providing a dataset, and learning the predictive basin-wise model based on the dataset. The dataset comprises, for respective saline aquifer locations of the basin, training samples. Each training sample includes a measurement of one or more geochemical variables of the predetermined set. Each training sample further includes a respective ground truth value. The ground truth value represents a concentration of the element at the respective saline aquifer location. Such a method forms an improved solution for analysis of a saline aquifer with respect to a given element of interest.
