    Description

    This application claims the benefit of Provisional Patent Application No. 61/521,392, filed on Sep. 8, 2011, in the United States Patent Trademark Office, the disclosure of which is incorporated herein by reference.

    Cell phones are very convenient, as they allow people to stay connected to friends and loved ones on the go, as well as enable people to conduct business when not in the same room. Certain activities, however, such as conference calls, long business calls, and playing games and videos, can drain the cell phone’s battery. In order to recharge the battery, individuals must be near an electrical outlet and must plug the phone into the outlet via a cord for extended lengths of time. If not around an outlet, the phone can die and the person can be stranded. An effective solution is necessary.

    The present invention is a solar cell phone with a plurality of small solar panels that can be used to charge the rechargeable battery of the cell phone, rather than using an electrical power source. The present invention can be especially useful for businesspeople who are constantly checking their email or talking to clients, as well as people who use their cell phones to watch TV, watch movies, play games, play music, and surf the Web. Individuals looking to reduce their electric use will appreciate the convenience and practicality afforded by the solar cell phone.

    Numerous innovations for solar powered cell phones have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.

    A FIRST EXAMPLE, U.S. Patent Office Publication No. 2002/0088486, Published on Jul. 11, 2002, to Chenx teaches a solar-powered device that is adapted to be disposed on a battery unit of a mobile telephone handset so as to charge the battery unit. The solar-powered device includes a light sensor, a photoelectric converting circuit coupled operably to the light sensor so as to convert light that is sensed by the light sensor into a corresponding current signal, and a current processing circuit, coupled electrically to the photoelectric converting circuit, for receiving and processing the current signal so as to result in a charging current that is adapted to charge the battery unit of the mobile telephone handset.

    A SECOND EXAMPLE, U.S. Patent Office Publication No.2005/0282591, Published on Dec. 22, 2005, to Shaff teaches a mobile telephone apparatus in which a solar power source is used to supplement battery power. A solar cell array is positioned on the surface of the telephone and supplies electric current to the telephone. A preferred embodiment of the present invention is equipped with speech recognition software that allows the user to issue commands (such as dialing the telephone) verbally to the telephone. In addition, this speech recognition may be used to operate an integrated AM/FM broadcast radio to allow the telephone to double as a radio. In an alternative embodiment, the solar mobile telephone is integrated into a headset to allow for convenient hands-free operation.

    A THIRD EXAMPLE, U.S. Patent Office Publication No.2006/0238163, Published on Oct. 26, 2006, to Chen teaches a mobile phone which includes a main body. The main body further includes a solar power module, a display module, and an input module (i.e., a keypad). The solar power module is adapted for providing electrical power to the mobile phone. The solar power module includes a solar cell panel configured for converting light energy to electrical power. The input module includes a control switch for setting the solar power module in one of the following states: “on”, “off”, or “storage”. Advantageously, the mobile phone can also be supplied with at least one heating pad disposed on the surface thereof, selectively controlled (e.g., on/off and/or a temperature chosen), to provide heat to a hand and/or other body part of a user.

    A FOURTH EXAMPLE, U.S. Patent Office Publication No. 2008/0143291, Published on Jun. 19, 2008, to Lin et al. teaches a communication apparatus with a solar energy charging function that includes a host and a display panel movably and pivotally coupled to the host to define a foldable mobile phone, and a solar panel is coaxially and pivotally coupled to a shaft of the host, such that the solar panel can be folded and covered onto an upper surface of the display panel. If the battery power of the mobile phone is low, users can individually lift the solar panel open from the display panel to charge the battery that is electrically coupled to the mobile phone, so as to enhance the power capacity, using time limit and battery charging requirements of the communication apparatus.

    A FIFTH EXAMPLE, U.S. Patent Office Publication No.2010/0167797, Published on Jul. 1, 2010, to Morichi teaches a cellular phone according to the present invention comprises a plurality of solar cell modules arranged on different surfaces of a casing, a plurality of electric power control parts connected to each of the plurality of solar cell modules, a mechanical form detection sensor as a state detection part for detecting a state of said cellular phone, and an electric power selection part.

    It is apparent now that numerous innovations for solar powered cell phones have been provided in the prior art that are adequate for various purposes. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, accordingly, they would not be suitable for the purposes of the present invention as heretofore described.

    AN OBJECT of the present invention is to provide a solar cell phone that avoids the disadvantages of the prior art.

    ANOTHER OBJECT of the present invention is to provide a solar cell phone that is simple and inexpensive to manufacture.

    STILL ANOTHER OBJECT of the present invention is to provide a solar cell phone that is simple to use.

    BRIEFLY STATED, STILL YET ANOTHER OBJECT of the present invention is to provide a solar cell phone which comprises a housing having a keypad, a display screen, other electronic components and a rechargeable battery. A diode switch within the housing is electrically connected to the rechargeable battery. A plurality of solar panels are mounted to the housing and electrically connected to the diode switch. The diode switch will allow the solar panels to supply electrical power to the rechargeable battery. An auxiliary battery within the housing receives electrical power from the solar panels. The auxiliary battery will store the electrical power to recharge the rechargeable battery when the diode switch is in a non-operative position, so that the rechargeable battery will continue to operate the keypad, the display screen and the other electronic

    The novel features which are considered characteristic of the present invention are set forth in the appended claims.

    What features to look for in a solar phone charger

    When you’re shopping for a solar phone charger, there are a few things to keep in mind to make sure you get the right one for your needs, including:

    How do solar cell phone chargers work?

    Having just spent a month (yes, a whole month!) with my family over Christmas (there was at least 11 of us at any given time sleeping and eating there), I have come to appreciate the need for an alternative method to charge my cell phone.

    Trying to find a plug that was not already occupied by other cell phones, tablets, computers, and ipods charging was next to impossible.

    This predicament led me to the pressing need to investigate an alternate means of charging my cell phone.

    I knew solar charges were a great option, as I was pretty sure I could find a free windowsill somewhere in the house.

    However, I did not know much about them or which one was right for my particular situation. So, I researched it, and this article is the result of my findings.

    I found this information extremely useful when ultimately picking out my solar charger and I am confident you will too.

    How solar chargers function

    A solar charger consists of three parts:

    Solar Panel

    The solar panel is made up of photovoltaic (PV) cells. These cells contain light-sensitive materials that convert sunlight into small amounts of electrical current.

    When sunlight shines onto the solar panel, the resulting electricity is sent to the battery, which is regulated by the charge controller. The sunlight can be direct, or indirect.

    Rechargeable Battery

    A solar charger can recharge the following types of batteries:

    The battery stores the electricity generated by the solar panel for later use by any electrical devices that are connected to it.

    This stored energy is available to use at any time, including at night.

    Charge Controller

    A charge controller regulates the amount of voltage delivered from the battery to the device it is connected to.

    How to charge the charger

    It’s simple, just like Ron Popeil says, ‘Set it and forget it!’

    • point the solar panel towards the sun at a 90-degree angle
    • while the charger is capable of charging in partially-cloudy conditions, full sunlight is ideal for a quicker charge

    Literally, this is all you have to do to charge your solar charger.

    How well do they charge?

    How well a solar charger recharges your device depends on the weather.

    When recharging your solar battery on a sunny day, with no Cloud interruptions, it will recharge much quicker and efficiently than on a cloudy overcast day.

    It takes around 3 hours to fully recharge a solar battery (this is dependent on the size of the battery).

    This means that on a sunny day, you will be able to recharge your device quicker than on a cloudy day because your battery would have charged quicker. Makes sense, right?

    When a solar battery is completely recharged, it will take around 10 hours to fully recharge your cell phone.

    how long do solar chargers last?

    Solar chargers generally last around 300-400 charges. So the life expectancy of your charger will depend on how often it is used.

    Limitations

    How to choose the right one for you

    There are many different types of solar cell phone charges available to you. Picking the right one for your particular use will ensure you have the best experience as possible.

    Home use

    Picking a solar charger for home use is not as easy as it sounds. While solar technology keeps getting better and better, the solar panel collects sun rays more efficiently from direct sunlight, not indirectly through a pane of glass.

    That being said, there are some solar chargers that are designed to stick in Windows, just be aware that they will not charge as fast or be as powerful as most directly charged batteries.

    This solar window charger sticks right to the window using suction cups. It’s small and perfect for leaving in the window while your phone charges on the windowsill.

    compare, reviews, solar, providers, online, cell

    One major drawback of this charger is that at only 1800mAH, it may not be able to charge your phone completely with a fully charged battery.

    Another window option is GreenLighting Solar Phone Charger, at 6000 mAH it boasts being able to charge your cell phone up to 1% per minute until it is fully charged.

    It uses a lithium-ion battery, and is pretty small, so it won’t obstruct a window view too much.

    With one large suction cup, you can leave it in a window at home and use it whenever your phone requires a charge.

    In the Car

    The same issue arises with in-the-car solar charging as at-home solar charging. Solar panels are less efficient when charging a battery from indirect sunlight.

    So again, please keep in mind that when charging your battery through a pane of glass, it will not be as fast as charging it with sunlight directly.

    Both solar charges mentioned above will work in the car as well, as they use suction cups to stick to the glass so they are not permanently fixed.

    Outdoors

    This is where solar chargers shine!

    Beautiful, direct sunlight is the solar panels jam.

    For outdoor activities such as hiking, backpacking, walking, jogging, rock climbing, or anything else you might get up to in the great outdoors, there are a few characteristics and features to look for in a solar charger.

    • battery type
    • size
    • weight
    • durability
    • water resistance
    • ability to charge with an overcast sky

    Troubleshooting

    If your solar charger is not charging your phone to a full charge, here are a couple basic reasons why.

    • Weather: a cloudy day could result in the rechargeable battery unable to receive a full charge, thereby rendering it unable to fully charge your device
    • Indirect sunlight: charging through a window pane may result in inefficient charging of the solar battery, similar to a cloudy day
    • Weak rechargeable battery: the solar battery may not be strong enough to charge your phone fully even when the solar battery itself is fully charged

    In order to avoid these common issues:

    • charge your solar battery with direct sunlight as much as possible
    • make sure you buy a solar charger that is strong enough to fully charge your device

    How much Solar Power do I need to Charge a Phone? Quick Guide

    With all the distractions around us, sometimes we need a break from our daily lives and head out into nature. It doesn’t matter if you’re hiking or camping under the stars; getting away will do wonders for your mental state.

    What happens when you’re miles from civilization and your cell phone goes dead? You can’t call for help if you don’t have a way to charge your device! That’s where solar power comes in handy.

    But how much solar power do I need to charge a phone?

    In this blog post we’ll go over everything you need to know about harnessing energy from the sun so your phone never runs out of juice.

    How much Solar Power do I need to Charge a Phone?

    A smartphone uses 2 to 3 watts from its battery when in use. The battery holds a charge of 1,440 mAh, or about 5.45 watt hours. A solar panel will need to provide a minimum of 5 watts when charging. Ideally 10 to 15 watts of charging power is recommended.

    A lower wattage means that you will need more time to charge your phone.

    In order to fully charge the phone battery, the solar panel charger voltage must at least match the voltage of a fully charged phone battery. A fully charged phone battery is 4.15 V (540 watts).

    As an example, let’s compare the voltage in a phone battery to the air pressure in a bike tire. If you want to fill the tire to 20 psi then you must have an air source that is at least 20 psi to move the air into the tire. It’s the same concept as applying voltage to charge a phone battery.

    Types of Solar Chargers

    There are two types of solar phone chargers; direct and battery bank.

    Direct solar chargers send power directly from the sun’s rays to your device.

    A battery bank solar charger collects energy in an external battery pack that can be charged by either sunlight or plugging into a wall outlet when needed.

    How does a Solar Charger Work?

    The solar panel converts sunlight into usable charging power for your phone. The speed at which this happens depends on the efficiency of how much light is received by nature. By using sunlight to make the electrons in solar cells flow in a circuit, this creates current and thus charges your phone battery.

    The amount of solar exposure however is affected by many factors such as weather patterns. Portable solar photovoltaic systems require direct sunlight on every single cell before they can produce electricity.

    So it’s important to keep this in mind when out in nature and needing to charge your phone.

    How long does a Solar Charger take to Charge a Phone?

    The time it takes for a solar device to charge your phone will depend on many factors.

    Portable solar panels are designed to be small. The batteries that they are charging generally have a very large capacity. So charging them completely takes a significant amount of power.

    As an estimate, a fully charged portable solar panel will recharge a phone with 5% battery life to full battery life in about two to three hours.

    It’s nearly impossible to calculate exactly how long it will take for a solar-powered device to charge a phone. That is because of the environmental factors.

    Keep in mind a portable solar charger is not designed with the idea of charging from zero. Instead they are designed to be a maintenance of charge. Maintenance charges always take much less time and energy.

    Is Charging Phone with Solar Bad?

    No, charging your phone with a solar charger will not damage your device. The two most important factors to be aware of are the voltage of the solar panel output and of the phone battery you’re connecting to.

    When you use a solar charger to recharge your phone, it’s important that the device be used minimally. Try not to use any apps or checking social media for awhile when charging with one of these devices in order maximize its efficiency.

    Conclusion

    So, if you’ve been looking for a way to ensure that your phone never runs out of juice again when you find yourself in the middle of nowhere, a solar charger might just be the answer for you.

    Hopefully this blog post has helped answer how much solar power do I need to charge a phone.

    Why our phones still aren’t powered by the sun

    Aside from screens that are prone to smashing, and disappearing headphone jacks (ahem, Apple), one of the most annoying things about smartphones is just how quickly their lithium-ion batteries drain.

    Even the latest handsets on the market, touting more advanced features than ever, rarely managed to last much longer than a day without needing to be plugged into a wall – if you’re lucky.

    It feels like there’s an obvious solution, right above our heads: the sun offers bountiful energy, and the idea of actually utilising solar power to power our phones is far from a fantasy.

    We’re used to seeing photovoltaic (solar) panels dotted about on houses and office buildings, and they’re being increasingly built into smaller accessories, like speakers and backpacks.

    And the good news is that many manufacturers – including the big guns of Apple and Samsung – are looking to see if the sun can be the answer to our battery woes.

    So if the tech is available, if research is being done into more convenient, sustainable ways of charging our phones, and if we’re all increasingly on board with the idea of using solar power, then why aren’t all our phones currently running off sunshine instead of the mains?

    The history of solar-powered smartphones

    Charting the history of solar-powered smartphones makes for an interesting, yet disappointingly bare, timeline.

    Samsung was officially the first manufacturer to bring a solar-powered phone to market, back in 2009.

    The ‘Solar Guru’, or Guru E1107, was launched in India to address the problem of regular power outages. The handset was able to provide between five and 10 minutes of talk time off one hour of solar charging.

    Months later, Samsung brought out another solar-powered device called the Blue Earth, touted as an eco-friendly product and launched in a much wider range of markets, including the UK, but it was withdrawn shortly after – sales figures are nowhere to be found, but it’s hard to imagine the technology was anything other than a failed trial.

    A year later, in 2010, Puma teamed up with Sagem to bring out the Puma Phone, a handset with a solar panel that was supposed to enhance the fitness capabilities of this ‘active’ phone, which featured step tracking and a GPS chip.

    However, the solar panel was merely there to keep the battery topped up, rather than provide the primary means of charging – the efficiency simply wasn’t high enough, despite the lower power needs of this feature phone.

    Since then a number of manufacturers have looked into the feasibility of solar-powered tech. But all seem to have come up against the same problems faced by Nokia, as documented in this blog post from 2012 about the company’s ongoing tests with solar-powered phones:

    When carefully positioned, the prototype phones were able, at best, to harvest enough energy to keep the phone on standby mode but with a very restricted amount of talk time. This means there’s still some way to go before a workable and care-free solution is achieved.

    Intriguingly, one of the issues presented by Nokia was this: The most substantial challenge is the limited size of a phone’s back cover, which restricts the extent to which the battery can be charged.

    Consider how much bigger phones have become in the nearly half-decade since, and you’d be forgiven for thinking that we should be able to power a whole house from the back of a Note 7 (if it didn’t set itself on fire first).

    Fast-forward to the present day, and the most interesting developments in solar-powered smartphones are coming courtesy of a partnership between Kyocera and Sunpartner Technologies.

    For the past two years, the companies have showed off a solar-powered phone prototype at annual mobile industry bash Mobile World Congress. The latest version of their device needs three minutes of sun in order to deliver one minute of talk time, and comes with an app to alert users about current charging conditions.

    It’s worth mentioning that Sunpartner Technologies have also partnered up with Alcatel, but we haven’t seen anything new from that pairing since last year.

    Perhaps one minute of talk time after three minutes in the sun doesn’t seem like an amazing trade-off – but that’s still a big improvement on the company’s prototype from the year before, which promised only 15 minutes of chat for a whole two hours of charging.

    What’s actually rather incredible about this technology is that the solar panel is in the screen, lodged just below the touch layer, so it doesn’t interfere with the design of the phone. Sunpartner claims the visibility of the display isn’t compromised, and can provide ‘perpetual energy’.

    This might sound fairly insignificant, but it’s a big deal. It means the phone can soak up the sun while you’re actually using it – older devices had to be turned upside down to capture the sunshine – and because the panel is under the surface of the screen, it’s way less prone to damage.

    There’s been no official release date for this Kyocera and Sunpartner lovechild, but sources are suggesting that we can expect to see the phone that was shown off at MWC 2016 out in the wild at some point during 2017.

    Of course, just because they don’t have anything to show us yet, that doesn’t mean a number of bigger and better-known names aren’t also experimenting with solar tech for their phones.

    For instance, the Patently Apple website has an entire section dedicated to the subject, which suggests it’s only a matter of time before one of the world’s biggest brands adds solar power support to its iPhones.

    What does the future hold for solar-powered tech?

    The Kyocera phone could set a huge precedent for the future of solar-powered tech. If Sunpartner’s transparent photovoltaic material delivers, it’s likely to be snapped up by many more smartphone manufacturers than just Alcatel and Kyocera.

    And there are plenty of similar materials being pioneered in the photovoltaic space. A company called Ubiquitous Energy, part of MIT, has created a kind of tech that acts as an invisible coating, designed to transform any surface into a solar panel.

    Up until now, solar panels have been dark, based on the science that darker and denser materials tend to absorb more light.

    Ubiquitous Energy’s material, however, is comprised of organic molecules, which can absorb both ultraviolet and infrared rays. As this light isn’t visible to humans, the coating looks clear.

    It also doubles up as a semiconductor, which means that when photons hit its surface, they excite electrons, causing them to flow as an electrical current to power your device.

    Sadly, the scale of the material currently can’t generate enough energy to be practical for use in phones – which leads on to another interesting consideration, about how much energy is actually needed to create the solar-powered technology in the first place.

    And that brings us to the most important question: are we there yet in terms of the technology to create a PV panel that can really charge up our phones?

    We asked Kevin Schofield, Director of Project Rome, to gaze into the future a little and guess how much energy would be needed to charge up a standard iPhone, as well as the time it would take to get it, and what that solar panel would look like.

    Based on data from The Eco Experts he told us: An iPhone needs around two hours of charge at 12w. If the PV panel is 17% efficient (according to the Eco Experts) then you would need a 70w panel (12w/17×100) in direct sunlight for two hours. A 70w panel would be 770mm x 676mm x 25mm.

    So basically you would need a 0.8m by 0.7m panel to charge an iPhone currently based on the available PV efficiency!

    In addition, we may all think we’re saving the planet by not plugging into the wall – but what about the time, money, effort and, erm, electricity needed to make your shiny new solar-powered phone in the first place?

    Schofield believes we’ve got some distance to go before the energy-saving benefits of using such a phone outweigh the environmental cost of making it in the first place.

    To truly consider environmental impact we must consider the energy, water and chemical and manufacturing processes associated with creating the PV technology, he says.

    This ’embedded’ environmental impact may just tip us over the environmental benefit edge.

    The other issue is how sheltered – literally – an existence we live these days. Human behavioural traits are as important as the tech when it comes to solar-powered smartphones.

    For the solar-powered tech built into your phone to work, you’d need to spend a considerable amount of time outside; not necessarily in direct sunlight, but in ambient light, which would still be tricky to guarantee in certain markets.

    That means people may have to change the way they behave in order to reap the solar rewards – most of us keep our phones stuffed into a or a bag for much of the day, after all.

    A new future

    There’s clearly potential for solar-powered smartphones in the future, especially if the materials currently being developed deliver.

    But right now, for a mixture of environmental and practical reasons, we shouldn’t be expecting our next smartphone to be solar-powered – or even the one after that.

    It’s pretty clear where solar-powered phones will be launched first: places without ubiquitous power supplies (and brighter days) will be the proving ground for such technology, as long as the manufacturing costs continue to fall.

    Cell towers have already been converted to solar power in places like India, replacing polluting diesel that require constant refuelling – if the same could be added to phones, it would revolutionise services for areas with limited power supplies, so the motivation to create solar-powered phones (or at least photovoltaic charging stations) is high.

    In the meantime, if you’re keen to be more environmentally-friendly when it comes to tech, it might be a Smart move to use electricity generated from your rooftop PV panels until the smartphone market has caught up.
