Abstract: Leading-edge units for a PV array comprising fastener or component holes for anchoring the array bonding the array and protecting array cabling. The leading-edge units provide a favorable aerodynamic shape to help deflect incoming wind, the channel rainwater and to protect the edge of the array. Methods having steps of placing modules contacting native topography or a smoothed or substantially flat portion of the ground in an array and holding the array together and down are also disclosed.

Abstract: Biodegradable pellet compositions comprising: a starch at about 30% to about 80% by weight of the composition, a plasticizer at about 2% to about 30% by weight of the composition; a flexibility agent at about 10% to about 40% by weight; a binder at about 3% to about 13% by weight of the composition; a hydrophobic agent at about 0.1% to about 5% by weight of the composition; and an emulsifier at about 0.1% to about 5% by weight of the composition. The compositions further comprise a defoaming agent where a biodegradable foam pellet is the end product. The compositions may optionally include a plant fiber.

Abstract: An earth mount enabled utility scale solar photovoltaic array has plural rows of solar panels supported on the ground so as to establish an earth orientation of the solar panels. Edge portions of the panels rest on a ground support area and provide mechanical support, and an end curb member abuts at least one edge of the arrangement. The panels are interconnected in at least one series-connected string extending in 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, routed to reduce “home run” connections at the end of the string.
