A second panel and a third panel are disposed on both sides of a first panel in the width direction, a fourth panel is disposed at a position symmetrical with the first panel with respect to the second panel and third panel, the respective panels have the same length and are disposed parallel to each other, and a step is provided with a gap between the first panel and the second panel or the third panel, and between the fourth panel and the second panel or the third panel.

A power conversion circuit is used in a solar array suitable for, e.g., roadside adjacent installation. The power conversion circuit includes an inverter with a first stage electrically coupled to one or more solar panels. A third stage of the circuit has a DC to AC converter that provides less than a 50 VAC load voltage to a load, and a second stage that is coupled between the first and third stages and provides an isolated electrical power coupling therebetween. A sync interface communicatively couples a controller to other controllers dedicated to one or more other respective inverters of the solar array via a sync signal. The controllers synchronize the third stages of the inverters via the sync signal. The third stages of the inverters are coupled in series to provide a load output voltage.

A roadway subsurface sensor system includes roadway housings arranged to define a surface to carry vehicles. Each roadway housing has a sensor assembly having a housing, and sensor layers received by the housing. Each roadway housing also has a drainage layer under the sensor assembly. An uppermost sensor layer from the sensor layers is to provide the surface to carry vehicles. The roadway subsurface sensor system further includes a management controller coupled to the sensor layers. The management controller is configured to process sensed data from the sensor layers.
