An earth mount enabled utility scale solar photovoltaic array having a plurality of solar panels is supported on the ground at edge portions of the solar panels. The panels are interconnected in at least one series-connected string, in which said at least one series-connected string extends along adjacent or closely adjacent solar panels along at least two rows so that the string has a distance between terminal ends of the series connection less than a lengthwise dimension of the solar panels constituting the string.

A multiple function microstructure with lotus and light trapping effects includes plural triangular walls with same and different heights and having a triangular cross section and arranged apart or staggered with one another, and a surface layer, a middle layer having zero to plural layers, and a bottom layer. The bottom layer and one of the other layers constitute a closed space to form an air spring, so that droplets can be bounced and separated from the surface of the microstructure. Each triangular wall has a cross section substantially in a smooth upwardly convex curve to prevent droplets from cracking while dropping. The microstructure selectively made of a hydrophobic material provides lotus and light trapping effects, and the microstructure selectively made of an oleophobic material provides a superoleophobic effect, and the surface of the microstructure may be coated with various type of chemical materials for different applications.

A solar panel cleaning system includes a brush connected by a hose to a fluid supply. The brush has scrubbing material, such as bristles, attached to a brush body for mechanically cleaning the surface of the solar panel. The width of the contact surface of the scrubbing material may be equal to the width of the solar panel, so that the solar panel may be cleaned with only upward and downward strokes. The brush body may further support a fluid manifold that receives the fluid from the fluid supply. The fluid manifold may include nozzles that emit the fluid under pressure onto the solar panel. The nozzles may project both frontward and rearward of the brush body so that the fluid sprays off the solar panel in front of and behind the brush. Spray patterns of the nozzles may overlap and impinge the entire width of the solar panel.
