This invention relates to portable solar energy units and those that may be easily installed to a fixed location on a larger scale. More particularly, systems and methods discussed herein are related to deploying solar energy panels.
Permanent installation of solar energy generation units involves considerably high labor costs due to their inherent, inefficient design from an installation perspective. For instance, a support assembly, such as a rack, may be installed to a desired location and the individual solar panels may be secured to the support assembly one by one. Installation of the support assembly and panels is extremely time consuming, and may require more than one person to install the panels. This issue is addressed herein with the versatile unfolding solar deployment system.
The following description relates to the design, architecture, and fabrication of a series of portable solar energy generation units which utilize new methods of panel deployment that can be configured for permanent installation or temporary applications. More specifically, these units are built from a common base system which then has application related parameters and design elements added to construct the required system specifications. The present invention enables a quicker, safer, and cheaper installation and operation cost of solar units relative to permanent units designed for roofs.
The units may be preassembled and may require little time or skill for permanent and/or temporary installation to either a standing structure or an appropriate ground foundation, which may include, but is not limited to, roofs, walls, awnings, sky-tunnels, signs, billboards, fences, outcrops, rock faces, and the like. Further, the units may be modular to satisfy various power generation and dimensional requirements.
The portable units are advantageous because of their simple and quick deployment and retraction and their ease of use. The units can be used for human portable needs, such as small scale power generation, and large needs, such as trailer based portable devices or generators capable of operating on a moving/stationary vehicle for civil, humanitarian, or military applications. The design described herein enables a larger power generating capacity for the size of the retracted device by allowing a larger number of panels to be deployed and retracted. Costs and system quality are critical factors for solar energy generating systems. The design described herein is based upon an innovative unfolding deployment concept which enables higher power outputs compared to similar sized devices currently available.
In one implementation, a solar deployment unit may include a chassis, a panel support provided by the chassis, and one or more solar panels coupled to the panel support, wherein the solar panels are folded together in a undeployed position, and the solar panels are unfolded in a deployed position.
In another implementation, a solar deployment system may include one or more solar units. Each solar unit may include a chassis and one or more solar panels. The solar panels are retained within the chassis in an undeployed position, and the solar panels extend from the chassis in a deployed position. Each solar unit may also include an electronic control unit provided within the chassis, wherein the electronic control unit manages the power generated by the solar panels.
In yet another implementation, a solar deployment unit may include a rolling mechanism providing a rotating shaft and a flexible panel. One end of the flexible panel is secured to the rotating shaft, the flexible panel is rolled around the rotating shaft to retract the flexible panel into an undeployed position, and the flexible panel is unrolled to deploy the flexible panel into a deployed position.
The foregoing has outlined rather broadly various features of the present disclosure in order that the detailed description that follows may be better understood. Additional features and advantages of the disclosure will be described hereinafter, which form the subject of the claims.

The following discussion provides a description of versatile unfolding solar deployment systems and methods. Versatile unfolding solar deployment systems may include one or more modular portable solar deployment units, which allow the systems to be scaled to meet desired needs. Portable solar deployment units providing improved panel deployment may be configured for permanent installation or temporary applications. These units utilize a common base system, which has application related parameters and design elements that may be added to meet the particular requirements and specifications for a desired system. The units enable a quicker, safer, and cheaper installation and lower operation cost for the solar units.
Preassembled units may be integrated with a number of ‘modules’ with varying functionality and complexity as per the power generation and dimensional requirements of the application. For example, permanent install designs may be expandable to allow the user to easily install additional arrays as required in a ‘plug and play’ fashion. These units provide fully customizable panel arrays, and the dimensions of the units customizable depending upon the restrictions of the application. Each individual array may contain 2 to 1,000 panels. However, as solar panel development progresses and more efficient organic or thin film photovoltaics become available, this number may increase accordingly. The power generation capacity for a versatile unfolding solar deployment system may scale in a range from 50 W to 100 MW. A versatile unfolding solar deployment system may have many uses including, but not limited to, portable, residential, small commercial, military, charity, non-government organizations (NGOs), large commercial to industrial power generation applications (such as solar farms), and many other applications.
The advantage of these portable units is their ease of use and speed of deployment and retraction. They can be used for individual portable needs, such as small scale power generation, to large scale needs, such as trailer based portable devices or as a generator capable of operating on a moving/stationary vehicle for civil, humanitarian, or military applications. While the retracted size of the device is relatively small, the versatile unfolding solar deployment system enables a larger power generating capacity. Costs and system quality are critical factors for solar energy generating systems. The versatile unfolding solar deployment systems and methods described herein are based upon an innovative unfolding deployment concept which enables higher power outputs when compared to similarly sized devices.
This can add to the development of an electrical supply to regional areas without the necessity to build a major grid infrastructure. By using the generation and storage components of the portable units, this can enable the implementation of a DC supply where necessary or by including a DC to AC converter, supply AC power required by many electrical components. This can be done by direct connection to the portable unit, or providing leads from the unit to home/work places.
Base Unit
The base unit design is the fundamental foundation upon which all structural permutations and possible conceivable applications for this invention are realized. The base unit provides a modular design that allows additional components to be added to provide additional functionality. Further, the base unit design provides a scalable versatile unfolding solar deployment system that can be expanded and/or upgraded to meet desired needs.
The solar panels in a versatile unfolding solar deployment system can be deployed in a number of ways. For example, the panels may unfold from a base unit into a vertical position. The panels may also be adjusted by pivoting, swinging, or rotating the panels into a horizontal orientation using a winch, crank, gear, pulley, or related mechanical apparatus. In other implementations, the panels may unfold from packed configuration into a standard horizontal orientation that is adjustable to a vertical position using a winch, crank, gear, pulley, or related mechanical apparatus. Base unit deployment can be achieved either manually (human powered) or can be automated using a motor or other appropriate actuation device (such as crank, winch, pulley, geared motor, hydraulic/pneumatic actuator, a combination thereof, and the like). The panels may be deployed in the horizontal configuration by use of hinges, slide arms, joints, rails, or interlocking connections.
In some implementations, flexible panels or smaller interconnected rigid panels (with small radius of curvature=>1 mm) may be stored in a roll. These panels can be rolled out and deployed along an appropriate structural support. In yet another implementation, panels may be deployed in a similar manner as an umbrella. These deployment processes may be assisted by employing a friction reducing mechanism(s) (e.g. guides, wheels, bearings or the like) to aid ease of deployment—in particular for larger sized systems.
Locking mechanisms 35 attached to panels 25 secures to first opening 55 in panel support 20 to lock the panels in a retracted position as shown, thereby preventing accidental deployment and/or damage to the panels. Locking mechanism 35 may be disengaged to allow panels 25 to be unfolded from chassis 15 for deployment of the panels. Locking mechanism 35 may be secured to a second opening 60 in panel support 20 when panels 25 are deployed to secure the panels in a deployed position (
a and 4b are illustrative implementations of solar deployment unit 10 in a retracted position.
Panel Protection/Cleaning—Post Deployment
An integrated semi transparent/transparent shutter mechanism can be incorporated to protect the solar panels. The shutter can either be manually operated by means of a crank, or slide arm or equivalent, or with the aid of a control module connected to a motor or similar driving device. This in turn can become an automated safety feature protecting the modules from storm or severe weather damage. Solar panels may be treated to have a hydrophobic coating which will aid in keeping the panels cleaner for a longer period of use between cleaning cycles—if necessary at all.
Base Unit Modularity and Support
a-6e are illustrative implementations of top, side, and front views of solar deployment unit 10 with and without a cover 65. Without cover 65, panels 25 of solar deployment unit 10 can be seen in a retracted position. As in the portable unit, electronics housing 45 may provide a variety of electronic components. Electronics housing 45 may also provide connectors, plugs, and the like to allow multiple solar deployment units 10 to be coupled together. The connectors, plugs, and the like may also allow solar deployment units 10 to be coupled to electronic grids, a home or build, batteries, and the like.
Installation/Setup
Once the versatile unfolding solar deployment system is on-site ready to be installed it may simply be positioned to the desired point of deployment and either mechanically attached or locked into position on a preinstalled installation base. For larger solar deployment units, this reduces the amount time a lifting device needs to be on-site thus reducing installation costs further. Portable solar deployment units (e.g.
Additional Modules Concept
The versatility of the solar deployment units is what makes it such an innovative solar power generation solution. For purposes where there is a requirement to tie the solar power generation system into the electrical grid, a separate module can contain all necessary electrical components/circuitry/connection equipment to enable an electrician to quickly and efficiently carry out the task. For more complex or larger capacity systems, the user may require a greater level of control of the system output and other critical power generation parameters. In order to power sensitive equipment or to accommodate any other specific requirements, additional modules providing the necessary functionality may easily be added.
Expandability
Base units may be connected in series/parallel with more than one unit at a time to expand the power generation capacity. The maximum number of units that may be utilized depends upon space and connection cable power ratings utilized in the system. It is conceivable that the number of arrays x of y panels may range from x=1 to x>1 million as demand for energy grows.
Scalability
The concept of adapting from small to large scale portable or fixed installations is detailed in the various specifications below. Minor modifications to the base unit in terms of materials choice and structural enhancements may be made for more applications and environmental specific requirements as detailed below.
Fixed Installation Specification
For ground installation, the system is installed on either a predefined foundation network on rough terrain. For example, a foundation may provide support for solar deployment unit and the solar panels or one or more supporting structures that are adaptable to different terrains may be utilized. For example, structural supports shown in
Rooftop/Standing Structure Installation
Versatile unfolding solar deployment systems may be installed on a roof with almost any angle/pitch made of any standard material. This can be achieved by means of customizable support legs/struts which are attached/locked into place along the structural shapes (or other shaped cross-sectional support framework) as shown in
Portable Units
Trailer/Vehicle portable systems may provide a systems ranging from 1 array to larger systems based on tractor trailer form factors. These systems can generate power ranging from 1 kW to 100 kW. The portable systems can contain a water treatment facility powered by the solar panels as described in detail below. The purification system is designed to remove filth and dirt particles through a series of filters, but also a desalination system powered by the panels can be attached to the purification system after the water leaves the filters. The housing of a filter system within the chassis of the portable system means that water can be pumped out electronically, filtered, and desalinated (as necessary) as part of the filter network.
Personal mobile solar deployment systems may encompass a small system weighing less than 60 lbs which has integrated wheels and a handle for ease of transport by a single individual. It may also contain integrated straps so that it can be carried on an individual's back similar to a standard backpack.
Flexible Solar Panels
The various solar deployment units may be deployed and installed in variety of different manners. For example,
Water Purification Systems
Valve 345 are utilized to control the flow of water to and from module attachment ports 325. If modules are attached, the valves can be arranged to cause water to flow through module attachment ports 325. Attachment modules may include, but are not limited to, UV treatment, nanofiltration, deionization, disinfection, PH treatment, additive treatment, bio-filtration, and the like. If there are no modules attached, the valves can be arranged to bypass module attachment ports 325.
Water then flows through filter 335 to water out 315. Filter 335 may be any suitable type of filter. For example, filter 335 may provided cone-shaped stainless steel mesh filters. Reversing water flow in the opposite direction allows backwashing and cleaning of filter 335. Further, filter flush ports 330 may be opened to flush biohazardous materials, particulates, debris, bacteria, and the like from the system.
During a filter cleaning operation, the flow through filter 350 is reversed to flush out particulates, debris, bacteria, and the like. When utilizing a pump that allows the flow to be reversed, the pump may simply be switched to provide reverse flow to clean filter 350. In other implementations, a filter cleaning pump may be attached module attachment port 325 to cause the reverse flow needed to clean filter 350.
Electronic Control System Module Options
Versatile solar deployment system may include a variety of features provided by an electronics control system module. Electronic control system modules may be provided in the electronics housing or chassis of a unit. Electronic control system module may provide solar tracking, electrically powered deployment, plug and play connections to an electrical grid or the like, monitoring, data logging, data communication, remote operation, connection to external power generation, external appliance control, and/or a combination thereof. The system may be GPS controlled and automated to provide solar tracking along a single or multiple axis. In other implementations, the system may utilize sensors (e.g. photo diodes) to provide solar tracking. Solar deployment units may provide DC electrical outputs. The system may provide electrical grid tie module to allow the system to be coupled to an electrical grid that the generated power is to be provided to. The system may also provide power production and monitoring systems with key parameter data logging. The system may include inputs for generators, wind power, hydroelectric power, geothermal, or any other means of AC or DC power production. Further, external power generator controls may be included as well.
When the system provides automatic deployment and retraction, the system will provide controls for deploying and retracting the solar panels. These controls may also control additional modular components installed in system. The system may utilize sensors to detect conditions and control the system in accordance with the detected conditions. Failsafe measures may be incorporated into the system (e.g. fuses, trips, breakers, malfunction alarm, notification by GSM telecommunication, notification by internet, or other forms of communication). The system may wired or wireless connected for network communication. For example, the system may transmit data to a desired location and/or receive control data from a remote location, thereby allowing the system to be operated remotely.
In some implementations, the system provides external connectivity to allow the system to receive software updates, to be serviced, to be programmed, and the like. An internal weather monitoring module may be incorporated to detect weather conditions. The system may include power interfaces that allow the number of units to be scaled to meet desired needs. The number of solar deployment units that may be utilized in a versatile solar deployment system is customizable. A display, such as a LCD, LED, color display, touch screen, or the like, may be utilized as a control module.
The system may also provide automated external appliance control. For example, if excess power is being created by the solar panels without the presence of adequate storage/electrical grid connection, the control module may be capable of adjust an air-conditioning system, hot water boiler, or any suitable appliance to use up the surplus energy.

Solar Farm Specification
Large scale permanent installation may be based upon a trailer mounted with preassembled solar power generation stations utilizing one or more solar deployment units. Each station is designed to deploy its solar panels while anchored from the trailer. The power stations are then connected to a predetermined foundation at the solar farm site. Once the station is locked to the predefined foundations the trailer is detached from the station. This reduces the need for consumable containers, protective packaging, and provides fast installation and ease of panel deployment.
