Abstract
A solar panel mount system includes a ballasted block support resting on a ground surface, a post pivoted to the block support at a lower pivot, and a solar panel frame pivoted to the post at an upper pivot with a center of gravity over the ballasted block support and facing a desired sunlight-receiving direction. The upper pivot is selected to be at a desired adjusted height. The frame includes a yoke supported at the upper pivot and support beams supporting a solar panel. A method of installation includes placing the ballasted block support on the ground, and attaching the remaining components at desired angles to locate a center of gravity of the solar panel frame over the ballasted block support, and fixing an angle of the solar panel frame at a desired sun-facing position. A related method includes interconnecting solar panel frames on posts in a generally straight row.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
(15) The phrase solar panel as used herein is intended to refer to elements of photovoltaic systems and solar thermal systems and/or combination hybrid systems using one or both, which systems are used to harvest solar energy from incident solar radiation, and in particular is intended to refer to solar electric arrays forming part of an electrical energy system and to refer to solar thermal (heat transferring) arrays forming part of a heat-based energy system and to refer to integrated PV plus solar thermal panels which capture both electric and heat energy from the sun's radiation.
(16) A solar panel mount system 30 (
(17) A related method of installation includes placing the ballasted block support 31 freestanding on the ground 29, and attaching the remaining components 32, 34, 37 at desired angles to locate the center of gravity of the system (including the solar panel frame 34 and solar panel 36) over a footprint of the ballasted block support 31, and fixing an angle of the solar panel frame 34 and solar panel 36 at the desired sun-facing position. It is noted that the ballasted block supports 31 can include a feature facilitating transport, such as fork tine grooves (see support 31 on left side of
(18) The ballasted block support 31 (
(19) It is contemplated that the present ballasted block support 31 can be used on stable or semi-unstable soil and ground surfaces. For example, the present ballasted block support 31 can be used on soft or moist soil and/or sand. Also, the present ballasted block support 31 could be submerged or partially submerged in shallow water, thus allowing the present system to be installed in a flood zone, an architectural pond, and/or a municipal or agricultural water/waste irrigation or treatment pond, such as where the solar panel system can be supported above the water's surface without adversely affecting (nor depending on a stability of) the underlying ground surface, but where it is not satisfactory to provide an in-the-ground support system.

(25) Beams 42 (
(26) It is contemplated that the beams 42 can be bolted using a single attachment bolt 69 directly to the beam 42 (
(27) Various methods of installation are possible. One method of installation includes, (1) constructing a ballasted block support 31 with brackets 44 and 45 (on site or off site) and placing the ballasted block support 31 in a desired location (or casting the support 31 in the desired location) freestanding on the ground surface 29, (2) attaching the post 32 to anchor brackets on support 31 using the lower pivot 33, (3) fixing the lower pivot 33 for best center of gravity position by selecting a best arcuately-spaced hole 50 for anchoring fixing bolt 51, (4) attaching yoke 41 at desired height on upper pivot 35 by selecting the best upper pivot hole from the longitudinally spaced holes 53, (5) fixing an angle of the yoke and thus the horizontal tilt of the solar panel 37 by selecting a best arcuately-spaced hole 62 for best sunlight-receiving orientation of the solar panel using fixing bolt 56 through chosen holes 62 and 55, and (6) operably connecting the solar panels to form an optimized solar energy system.
(28) The illustrated ballasted block supports are precast concrete. However, it is contemplated that the innovative ballasted block supports can be made from (or made to be filled by) any local material suitable as a heavy ballast. For example, it is contemplated that a hollow support shell (fully hollow or partially prefilled) can be constructed of any suitable material (e.g. concrete, metal, wood, plastic, composite, stone, clay, or other) and filled by suitable solid low cost fill/ballast material that is locally available (e.g. concrete, clay, stone, metal, energy storage batteries). It is contemplated that the present hollow support shell (fully hollow or partially prefilled), if made sufficiently rigid, can be made to retain non-solid heavy ballast materials (e.g. sand, debris, dirt, slurries, soil/sand mix, water, combinations of same, and/or other).
(29) Advantageously, the present innovative system described above is able to provide self-ballasted mounting systems for solar panels with mounting footprints allowing it to replace the need for penetrative solar mounting systems (e.g. driven vertical-support posts, lag screws for roofs, augers for ground soil). Further, it provides hardware that allows for angular adjustment of generally vertical mounting posts that support a solar collector array, but does so without earth-penetrating mounting posts or poured concrete foundations. Still further, its hardware can be adapted for many different installations, such as even on rooftop situations, where it is desirable to not penetrate the roof, yet stably support the solar system at an optimal sunlight-receiving angle. Another advantage of the present system is that it has an ability to meet local codes and generally accepted engineering standards for wind-loading and/or seismic requirements for a completed installed system. Notably, the present innovative system is useful in installations on EPA-remediation sites where penetration below a capped landfill is not allowed, or on a membrane covered landfill site, or submerged in shallow water ponds or in flood zones, where penetration is not an option or is not desirable.
(30) The present innovative system also provides a system that takes advantage of financial and tax incentives due to the nonpermanent nature of the present ballasted solar mount system. Specifically, it is noted that ballasted and nonpermanent installations can be considered accessory equipment and thus are not taxed as an installation/capital asset tax basis. Thus, permits from local governments can be obtained by legally describing the installation as temporary (as opposed to permanent). Thus, a permit to cover the landscape with a ballasted solar system can be permitted as a temporary structure, providing significant tax incentives and tax advantages.
(31) The present innovative mounting system can be used in substantially any earthly location (latitude and longitude) and most soil conditions (e.g. rock, lava, sand, sub-polar tundra, polar ice). Also, the present innovative system is portable (or at least semi-portable) so it can be readily moved (or moved after subassembly). This enables powering of seasonal or temporary expeditions, geological exploration for mining, oil, and/or gas, or military requirement. For example, it is contemplated that the present innovative mount system can be used to bring electric power to storm ravaged recovery zones, refugee camps, and other disaster or war-torn geographies.
(32) Notably, the present innovative mount system itself is capable of supporting a solar panel array(s) in a most stable gravitational position (with center of gravity over a best location), yet adjustably supports the solar panel array(s) in an optimal angular position for receiving sunlight, and also adjustably supports the solar panel array(s) of the system in a relatively coplanar condition despite undulations and disruptions in the underlying ground surface.
(33) An advantage of the present innovative mount system is that it can be used to support solar panels which create electric power (photovoltaic panels) and/or thermal power (e.g. hot water or hot air), or hybrid combinations of both.
(34) It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
