Description

FRAME HANGER APPARATUS FOR PHOTO VOLTAIC PANEL AND BATTERY

BACKGROUND OF THE INVENTION

1) Field of the Invention

This invention relates to a frame hanger apparatus and assembly method for easily installing and hanging a photovoltaic (PV) panel and optional battery module from an external window. The present invention in a preferred embodiment comprises a pair of mounting brackets, PV frame sub-assembly and support strut, PV panel and battery hanger and module, which can be assembled rapidly and fixed from within the building via the window, without needing external ladders or scaffolding.

2) Description of the Prior Art

There is substantial and diverse prior art on photovoltaic assembly apparatus, frames, tracking systems, multi-PV array systems (e.g. US5228924 by Barker et a!, US5 125608 by McCaster et at), roof mounted systems, mobile mounting systems for signage and road-construction as well assembly structures for individual panels or panel strips (e.g. US6870087 by Gallagher) or for adding or incorporating PV layers or material onto or as part of window frame or glazing (e.g. Application US 20090139562, or window fabric US5128181 by Kunert, US6646146 by Fronek et al). However, such prior art and few systems relate to simple and compact methods and assembly frames for securing panels on walls or windows. Some prior art exists for hanging apparatus from telegraph poles or signage with a variety of mechanisms (e.g. US4265422 by Van Leeuwen), and simple methods exist for rail or roof/wall based brackets (e.g. US application 20090230265) or as part of curtain walls (e.g. US20100071310) however, no such examined prior art discloses a simple frame apparatus that can be easily adapted for different size panels and window widths, and easily installed from the interior of the property through the window to hang compactly below the window.

To the best of the applicant's knowledge, the prior art, whilst suggesting some features and numerous variations relevant to photovoltaic assembly apparatus and frames, the prior art has not disclosed some of the highly advantageous features of the present invention discussed herein.

SUMMARY OF THE INVENTION

The frame and hanger apparatus and assembly method of the present invention, in its preferred embodiment comprises a pair of generally inverted L shaped mounting brackets, a support strut, a Photovoltaic frame sub-assembly, battery hanger sub-assembly, battery module, Photovoltaic panel, electrical contacts, wires and tightening screws. Said L shaped mounting brackets formed from a right angle cross section with a lateral U shaped rectangular groove off the corner with a fastening screw for affixing the support strut. Where said L shaped mounting brackets are designed to be screwed into the opposing side walls of the window frame by means of a screw or bolt through a hole in the right angle cross section. Said support strut is preferably formed as a square tube cross section, and is designed to hang longitudinally and perpendicular to the L shaped mounting brackets and rest and be fastened into the corresponding U shaped groove on the opposed L shaped mounting brackets, and contains some optional screw holes for extra fastening or hanging of the battery hanger sub-assembly, where said battery hanger sub-assembly is shaped to receive and enclose a battery module with electrical contacts and wires for connecting and storing energy from the Photovoltaic panel or from an alternate supply via a wire connected through the wall or window frame into the room. Said Photovoltaic (PV) frame sub-assembly preferably comprising two opposing L shaped frame supports connected by a lower frame strut, which is sized to the length of the PV panel, where each frame has a small right angle cross-section and overall forms a support frame for holding the PV panel, and where said lower frame strut has locking pins corresponding to holes in the edge of the PV panel for fixing and positioning the PV panel on the lower edge. Where * said L shaped frame supports each have a fastening screw and a short orthogonal bar at the corner, where the orthogonal bar has a right angle cross section and is shaped to be hung onto the support strut and preferably fastened via a short groove for a bolt fixed to the support strut. Said Photovoltaic panel being formed in a usual manner with a surrounding edge frame or casing, where said edge frame has holes drilled in one side to correspond with the locking pins on the PV panel assembly lower frame strut, and holes on the upper side edges to correspond with the fasteners on the PV frame sub-assembly, and may optionally support handles to facilitate carrying or lowering the panel into position. Said PV panel also supporting electrical contact means or wires to connect to the battery module or through the wall or window to electrical apparatus or devices inside the building. In a further embodiment said battery module could form a part of the PV panel casing or be attachable to the PV sub-frame assembly directly.

Said support lower frame strut on the PV frame sub-assembly, and corresponding support locking pins, and holes for fastening screws being varied to accommodate the appropriate size of PV panel for the unit, and said support strut being sized to be longer than the PV panel length and to be longer than the typical window width for the PV frame unit, and assembled at the factory or distribution side. Said support strut could be left at original length or optionally cut-down on site to be closer but still wider than the overall window width. In a further embodiment said support strut could be formed as an extendable tubular strut, capable of being sized to fit or connect directly to the mounting brackets.

Said L shaped mounting brackets and corresponding L shaped frames support are suitably shaped to provide a cantilever benefit by placement to connect with the wall at the lower edge under the window, and are also suitably shaped by means of the L to over hang and avoid contact with the window sill, though a larger L could be provided for exceptionally wide window sills.

A significant feature of the overall apparatus is that it is capable of being assembled, fixed and placed into position through the window without needing an external ladder or scaffolding. Said method of assembly preferably involving a) positioning a drilling template guide (such as a piece of paper or plastic with hole position marked) and drilling a hole and placing a raw plug in opposed walls of the window frame wall (or window frame), b) attaching the L shaped mounting brackets to the wall by means of a screw or lock bolt, c) placing the support strut into the U shaped grooves on the L shaped mounting brackets and tightening the fastening screws, d) placing the battery hanger assembly (if being used) onto the support strut and fastening into place, and then placing a battery module unit into the hanger assembly, e) assembling the PV frame sub-assembly inside the property, by attaching the lower frame strut to the two opposed L shaped frame supports by means of two counter-sunk screws and nuts at the corners, 0 placing said PV frame sub-assembly out of the window onto the support strut, where said orthogonal bar groove on the L shaped frame supports is positioned over a corresponding fixed bolt on the support strut, g) lower and slide the PV panel into the frame to engage with the locking pins on the lower frame strut, and then tightening the side panel tightening screws, h) connecting the electrical contact wire from the battery module or PV connection through the wall.

Said overall assembly being removable in a similar reverse method, such that it could be relocated or moved to a subsequent property. Said overall assembly also being adjustable to fit the window size by means of different holes on a longer support strut corresponding to different sizes of PV frame sub-assembly. Said electrical contact wire may be optionally placed by drilling a hole through the window frame or cutting a small recessed groove in the side of the window frame or window panel, and may preferably be a semi-stiff wire or stiff tube containing the wire, with contact pins/socket at the end to facilitate pushing the wire through the wall and connecting to a corresponding socket on the battery module.

Said overall assembly is well suited for placement from Sash windows, where a window panel slides upwards or with side-ways sliding panels. Similarly by positioning the L mounting bracket at a lower point, or by using a longer L unit or shorter PV panel, the overall assembly could be positioned below a window sill line on windows that require a full opening externally from a side hinge or side hinges. For windows which fully open to the side, making it difficult to mount the L bracket in the optimal placement, a 7' shaped angular mounting bracket could be provided to be fixed flush or into the window sill.

Said battery hanger assembly also has the benefit of providing a good and convenient location for a battery unit module, without needing to rig up additional wires or fit out cupboards in the property to store batteries, and have the benefit of being located outside or external to the room, to avoid the need or perceived risk of having a battery unit inside or close to household users. In a further embodiment said battery unit could house additional insulation or have a warmer circuit in the event of a chemistry being used that had poor performance at low temperatures, however, typically such temperatures correspond to times of the year when solar generation is weakest. Similarly if this became an issue the hanger unit could be removed and placed inside the property where the battery would be largely powered by the AC mains back-up. The placement also provides a mechanism of replacing or maintenance on the battery, given that many solar systems often fail due to battery management issues or poor cycle performance over time. Similarly the panel is readily accessible for simple cleaning or being slid out to be cleaned -as PV panels often degrade when dirty or when exposed to bird droppings, which provides a further significant advantage over roof based solar PV systems.

Said overall system may be combined with an overall battery management or energy management hub unit that can optionally receive a back-up AC mains supply, which manages charging of the battery module or topping up the battery when solar resources are low, or from an off-peak or low energy tariff at other times of the day, so that the overall PV and battery module assembly can provide a source of DC electric power from the hub, or via an inverter as an AC supply or via a grid tied inverter provide power to the household AC circuit. Where said DC electric power may be arranged in the hub to provide power to a plurality of DC power sockets for power to DC appliances such as computers or mobile devices, or to a DC sub-circuit connected to other devices, such as light switches and DC LED or CFL lighting or to further DC sockets. Where said DC energy management hub and DC sockets may convert DC to the appropriate voltages and requirements of end devices, or manage a DC power network accordingly for a range of DC sub-circuits, devices, as for example by the Moixa Energy system, apparatus and methods of application US 20100076615 by Daniel et al. Said wire from said battery module and PV panel, may alternatively be connected into a DC power inlet, such as in a DC light switch to provide power toa DC power network, or may be connected with other similar hanger and frame apparatus and battery / PV sources to form a higher voltage or higher current power supply for an energy management hub or electrical devices in the property.

n a further preferred embodiment said support strut could support a second or further battery hanger assemblies, or similarly over a wider window length support additional solar PV sub-assemblies in a row.

Said overall apparatus being capable of being packaged when unassembled in a flat-pack assembly where a co-planer arrangement of solar panel and supporting mounting brackets, support strut, PV sub-assembly frame, and battery module and pack, to form a compact easily shippable or movable unit. Where in a preferred embodiment said flat-pack casing also contains a small wheel in one corner to facilitate rolling or moving easily.

A benefit of the overall approach is to allow a householder or building occupier to rapidly install solar panel resources from windows in the property, which may provide useful DC power to nearby devices or contribute power to the household electricity network. This would allow flats or buildings with multiple units without easy access to roof, or without permission or ownership of the roof, to install a solar system, and such solar systems may also be favourable with certain planning rules in many territories. Such systems also have the benefit of portability in that they could be installed in windows of a property but removed and taken with the occupier when they move to a new property, or for leisure or remote or rural homes to easily allow the valuable PV panel and/or battery pack to be removed and stored when the property is not occupied for a period of time for security reasons.

A benefit is that such systems could be self-installed by a DIY (do it yourself) enthusiast with similar skill as installing a shelf, and without needing the upper body to lean out of or through a window to fasten awkard components at difficult angles from a window, since the overall apparatus could be assembled inside the property in the aforementioned stages, potentially even by a person kneeling down by a window, and with pins or fasteners designed to position automatically or tightened with one hand through the window frame. Such systems could also be rapidly installed in a short home visit, in a similar manner to fixing up a satellite TV receiver or home cable system.

A further benefit of such systems with PV and battery module is in combination with a series of low power DC electronic appliances, such as a home office environment, typically comprising a computer and LCD or LED display screen, router modem or broadband connection, wireless router, printer, powered speakers or hubs, mobile electronic gadgets and phones, desk and room lighting.

Said systems may preferably be packaged with a energy management hub and peripherals suitable to power such a home office environment, devices and lighting, and would have the benefit of enabling said loads to be powered off-grid via the PV panel apparatus, or off-peak via a low energy tariff charging of the battery module, thereby reducing household costs as well as carbon emissions. Said systems may also be of benefit to be distributed to workers or with grant and corporate support, given the overall benefits on reducing costs and carbon, as home working can lead to an increase, of about a tonne of carbon, in additional electricity and heating costs, though does have the benefit of displacing or removing commuter travel cost and carbon impact.

Said systems in combination with such aforementioned computing, communication and lighting devices, could also provide power in a power cut, or be of benefit for households that are off-grid and use an occasional local generator to power high load devices in the home, and top-up batteries on such systems. Said systems could also be combined with household infrastructure such as security systems or DC electric motors and pumps for ventilation or household heat recovery or with Passive house systems.
