A mounting system for mounting a solar panel assembly to a base assembly includes a panel support bracket, a base bracket and a clamp configured to exert a compressive force to hold the panel support bracket and the base bracket together. The clamp comprises a V-shaped clamp body that includes a pair of legs that are spring-loaded to oppose an approximation of the legs by an external compressive force. The clamp includes a pair of receiver slots, with each of the pair of receiver slots located on a corresponding one of the pair of legs. The pair of receiver slots collectively provides a clearance to admit the panel support bracket and the base bracket when the legs are compressed together.

An arc detection circuit includes a current detector and arc determination unit. The current detector detects a current flowing through a transmission line which connects an electric power supply device and an electric power conversion circuit. The arc determination unit calculates, from a result of measurement of the current, an area of interest and an area for comparison. The area of interest is an area of a region of interest defined by a predetermined frequency range and predetermined time for determination. The area for comparison is an area of a portion in which detected strength exceeds a predetermined strength threshold in the region of interest. The arc determination unit determines an electric arc has occurred when a ratio between the area of interest and the area for comparison exceeds a predetermined area-ratio threshold.
