A transportable, self-contained, solar power system comprised of a plurality of individual solar power arrays, each array being contained within a transportable frame. Each array is folded into a frame during transportation. Upon reaching a desired location, the frame is positioned at a desired location. The frame then acts as a base while its solar power array is activated and deployed. The array has the capability of tracking the position of the sun during deployment. Each frame has a global positioning system (GPS) and a controller containing a chart of sun locations for a given location. The controller positions a frame's solar array to maximize the array's exposure to the sun. Each frame has a battery system, enabling a frame's solar array to self-start after a period of darkness.

A degradable plastic film for use as an agricultural mulch film comprises two longitudinal bands each adjacent to a respective longitudinal edge of the film, and a middle section between the bands. The bands and middle section contain degradants. In use, the bands along the edges of the mulch film are buried in the soil and the middle section is exposed to sunlight. By reason of different degradants in the bands and middle section respectively, or different levels of the same degradants, the entire film degrades by the time of the next cycle of cultivation. The film is produced by means of extrusion from two extruders through one circular die which has a die opening with one segment which receives resin with one degradant and another segment which receives resin with a second degradant. The extruded cylindrical film is blown and then slit longitudinally.
