NOVELTY - A series of spaced apart rotary tubes mounting solar tracking panels (64), form the rows (62) of the panels. A shade structure (66) is positioned at a preset location between some of the tubes, by posts (88) and bars (90), to provide a shaded region (92). An assembly mounts each tube above a support surface. A tilting assembly selectively rotates each tube about its axis. The panels are photovoltaic (PV) panels.    USE - Modular shade system with solar tracking panels, such as photovoltaic panels, for use as shade for cars, shade for outdoor activities, agriculture, aquaculture, and to promote various events, while generating electricity used for charging batteries, producing hydrogen from water, or being transformed into alternating current which is fed to commercial electrical grid, and for installation in parking lots, carports, pavilions, gathering places for education, roadways, parks, campuses, watersheds, reservoirs, canals, open areas adjacent to buildings, greenhouse or nursery for plant cultivation, traffic lanes, and open areas, and for use as modules for providing illuminated walkway, passive/active night time illumination, planter modules for growing plants, skylight modules, mounting modules for supporting structures such as flags, antennas and cellular repeaters, and modules with modular panels for use as acoustical control panels, seating elements, playground elements, restroom elements, sign elements, antennae modules, payment machines, stage elements, rail transportation elements, fuel-cell charging systems, hydrogen storage devices, inverters for converting DC to AC electricity, electrical wireways, and elements facilitating roller skating, ice skating, car shoes, horse riding, housing for homeless persons, farmers markets, soccer matches, tennis matches, concerts, light shows, fitness.    ADVANTAGE - Renewable electricity is produced by mounting the PV panels at an optimal angle with respect to electrical and wind performance, by tilting the tubes. The shading region serves as parking lot, or place for growing shrubs or trees. The shade system with the PV panels, has several uses, and ensures economic use of outdoor space.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for photovoltaic assembly.
