CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the priority benefit of U.S. Provisional Patent Application No. 62/138,311, filed March 25, 2015, the disclosure of which is incorporated herein by reference in its entirety.

FIELD

[0002] This disclosure relates generally to a solar panel system that uses renewable energy obtained from sunlight to power an electrical system, and more specifically, to a configuration of a solar panel system that reduces the horizontal surface area needed for operation, alleviates the need for careful positioning of the solar panel system and uses solar energy to power a direct current (DC) or alternating current (AC) to charge a battery to provide electrical power to a DC or AC electrical load.

BACKGROUND

[0003] Solar panels can be used for collecting energy from the sun for direct use or storage and often include multiple solar cells mounted securely on a surface. Solar cells are typically made up of photovoltaic material that absorbs photons from the solar energy. The photons strike the photovoltaic surface and transforms the solar energy into electricity, e.g., for commercial or residential applications. Such solar cells are typically arranged to cover a large horizontal surface area. For example, a conventional solar panel system may include solar panels mounted securely on a frame with the photovoltaic surface oriented facing the sun or energy source. In some examples, solar panels may be mounted on a roof or in an array of grids in a field

[0004] There can be certain drawbacks, however, to having the absorbing photovoltaic surface oriented facing the sun or energy source, especially for solar panels having a large horizontal surface area. For example, such a solar panel system can be expensive, heavy, difficult to transport and store, difficult to maintain, difficult to optimally position, and aesthetically unpleasing. Additionally, in conditions where the solar panel system may be shared by several end using devices or need to be in close proximity with other end using devices, it may be beneficial for the solar panel system to be portable. As a result, there remains a need for new and alternative solar panel systems. BRIEF SUMMARY

DETAILED DESCRIPTION

[0033] The following description is presented to enable a person of ordinary skill in die art to make and use the various examples. Descriptions of specific devices, techniques, and applications are provided only as examples. Various modifications to the examples described herein will be readily apparent to those of ordinary skill in the art, and the general principles defined herein may be applied to some examples and applications without departing from the spirit and scope of the present technology. Thus, the disclosed technology is not intended to be limited to the examples described herein and shown, but is to be accorded the scope consistent with the claims.

[0034] Provided herein are solar panel systems suitable for use in a variety of applications, including, for example, remote area power, emergency power, disaster relief, back-up power, military, residential, medical equipment, water purification, water pumping, stationary refrigeration, mobile refrigeration, computer systems, communication systems, remote satellite up-link systems, battery charging, engine generators, uninterruptible power supply (UPS) system charging and power tools. In some examples, the solar panel systems provided herein may be used to charge a UPS system. UPS systems, e.g., battery back-up, flywheel back-up, supercapacitors, or compressed air generators, are designed to provide emergency power to a load when the grid power input fails. The solar panel system can be used to power the aforementioned applications either fully or in-part.

[0035] In some examples, having to transport energy to remote or secluded locations may not be cost effective, for example, in the case of small-scale applications. Thus, by being able to locate die solar panel system in proximity to the end device that the solar panel system is powering (e.g., appliances), the costs of electricity distribution infrastructure can be reduced. Moreover, energy losses due to transmission and transportation over long distances can be reduced. The solar panel systems detailed herein can be scaled up and multiple systems may be connected together in order to operate on a large industrial scale, such as for utility scale power plants.

[0036] The solar panel systems detailed herein can be used continuously or intermittently, and can be connected or not to the main utility power grid.

The solar panel system may also comprise one or more solar inverters. Moreover, in order to obtain maximum efficiency, the solar panel can be connected to a sun-tracking device. A person of ordinary skill in the art will easily recognize that battery banks, solar inverters and sun-tracking devices are well-known technologies that can be used in conjunction with the solar panel system detailed herein. The solar panel system described herein is used to produce a direct current (DC) or alternating current (AC) in order to charge a battery to provide electrical power to a DC or AC electrical load.

The curved solar panel units 804 may be parabolic-shaped or circular-shaped troughs that are mounted to or over the solar cells 822. In some examples, solar panel system 800 can include parabolic-shaped solar cells and a trough coated with a reflective metal to focus light as a diagonally positioned light-splitting structure. When sunlight hits die trough 823, light can scatter and be directed to filters (not shown). The filters can allow only particular wavelengths or bands of wavelengths of light to pass through to the solar cells 822 and reflect the remaining wavelengths either away from or toward other filters. In some examples, a metallic sheet with slits (e.g., metallic sheet 714 illustrated in FIG. 7A) can be employed as a filter. In this configuration, the solar cells can be optimized to only absorb specific wavelengths of light This can allow the solar cells to be more efficient in producing electricity.

[0094] In some examples, plurality of solar cells 822 can be oriented such that the absorbing surfaces of plurality of solar cells 822 are substantially parallel to the sun.

In some examples, additionally or alternatively, one or more support panels 832 can be used to route electrical connections or wires from the plurality of solar cells 822.

[0097] Solar panel system 800 can be mounted or configured such that at least one outer casing 810 is oriented directly facing the sun. As a result, the horizontal space occupied by solar panel system 800 can be reduced when the total absorbing surface area of solar panel units is greater than the footprint. In this manner, the footprint of the solar panel system can be reduced without compromising efficiency and/or amount of collected light rays. In some examples, positioning device 840 can be configured to rotate solar panel system 800.

Positioning device 840 can include or can be coupled to a processor or controller. The processor or controller can rotate solar panel system 100 to exchange solar panel units. [0098] The solar panel units of the solar panel system detailed herein may be electrically connected to a battery, generator or other device, which can receive an electrical charge from the solar cells. The solar panel system may thus be configured with electrical wiring or other components known to those of skill in the art to provide electrical power. The battery, generator or other device may be connected, either directly or indirectly to a load for which electricity is desired. Thus, in some examples, a solar panel system can comprise solar panel units, as provided herein, and a battery, generator, or other device electrically connected to the solar panel system thereby receiving an electrical charge from the solar cells, and configured to provide electrical power to a load electrically connected to the battery, generator or other device.

Storage 982 can be connected to storage 984. Storage 984 can be connected to generator 986, which can be configured as provide power to structure 988. In some examples, storage 982 can be a high pressure storage unit, and storage 984 can be a low pressure storage unit. Solar panel assembly 990 can be configured to fill up storage 982 with electrical energy from solar panel system 900, while storage 984 releases energy into generator 986. Due to the pressure difference between storage 982 and storage 984, electrons from storage 982 can flow kinetically from a state of high potential energy to storage 984, which can have a state of low potential energy. In this manner, uniform power can be supplied to structure 988 both when solar power system 900 is exposed to low levels of solar energy (e.g., at night) and high levels of solar energy (e.g., during the day).

[0100] Thus, in some examples, the solar panel system includes a battery bank. In some examples, the solar panel system is connected to a solar tracking device.
