Abstract

The present invention discloses a method (300) for determining shading loss over cloud-covered solar modules (102). The method (300) comprises a pyranometer (104) to determine PoA irradiance values, and an SMB (108) to measure/record electrical data of the solar modules (102) i.e., current, voltage. The values such as SMB current (108) and PoA irradiance are transferred to be tracked by an output meter (110) through wired connections. Further, the values are transferred to a computing unit (112) for processing to determine the cloud cover (106). The determined cloud cover (106) values are transmitted to a monitoring device (114) through a communication unit (218) to display instances at which the solar arrays (102) were under the cloud cover (106). The determined cloud cover instance discloses low performing SMBs (108) with which the solar modules (102) were connected and helps to optimize those low performing SMBs (108).

Abstract

The invention provides a system and method for reducing power loss in a photovoltaic power station. Photovoltaic modules (102) with same or nearby length electric cables (104) are grouped (106) together. Clusters (110) of similar length electric cables (104) are formed using clustering modules (108). The clustered (110) electric cables (104) are connected to compartments (114) of an inverter (112). Similarly, the compartments (114) of each inverter (112) present in the photovoltaic power station receives clustered (110) similar length electric cables (104) from groups (106) of photovoltaic modules (102) comprising same or nearby length electric cables (104). Power loss in the electric cables (104) of the photovoltaic modules (102) is reduced by this way, thereby reducing overall power loss in the photovoltaic power station.

Abstract

The present invention provides a system and method to reduce the power losses in PV installations. The power loss in the DC cables over a long distance from the PV arrays to the inverter occurs due to various factors which can be reduced by optimizing the cable length between the string monitoring box and the inverter and thus, gradually increasing the number of PV modules in an individual array as the distance between the string monitoring box and the inverter increases. This results in optimum electric power transmission through the cables and reduces the power loss. The disclosed invention is applicable for PV installations established over a large area. Application of the disclosed invention ultimately results in power reaching the inverter from the PV arrays with reduced loss.

An intelligent inline sensor for a PV string monitoring is incorporated inside an inline connector. The inline sensor is configured with a current/voltage measuring PCB to measure current/ data along length of a wire or cable connected to PV strings and various modules in a solar power generation system very close to the string. Further, the inline sensor may transmit the measured data to the remote monitoring devices, where each monitoring device includes Graphical User Interface (GUI) to indicate alert indications of functioning or non-functioning modules in the solar power generation systems. The GUI displays the data in graphical representation.
