Did my ability to search for things intelligently on the internet die when Google search did or are there legitimately no personal umbrellas with solar panels and a battery pack? Like I feel like that would be an obvious thing, and there’s a bajillion beach umbrellas and patio umbrellas that have solar panels. How are there no personal versions for wandering around on a sunny day with portable shade that gets you a charged battery pack? Is this a thing and I just can’t find it or does it not exist yet and all of science has failed me in every way possible?
Sorry for the terrible AI picture, I didn’t create it I just found it on the internet and it was the only one I could find because these apparently don’t actually exist.
A device, which is only used when it is really cloudy for photovoltaics has to be one of the dumbest ideas ever.
Never used an umbrella to shield yourself from the sun?
Yup this is the smart use I’m sunny regions.
Here is one…sort of: https://moolsunpower.com/products/40w-foldable-solar-umbrella?variant=40967191167173&country=US¤cy=USD&srsltid=AfmBOorDEQt36eFhOqOvwk6eMQWBxoBowGNXAR2_1P-6eZXD8X82HWZIhy4&gQT=1

Ah OK!
I am British, so no
I actually did not, and here around, I don’t see anyone do that. I believe climate and culture are the factors influencing the popularity of using an umbrella as mobile shade.
Im beginning to see more people actually parasoling in the southern US and if im being honest… I’ve been tempted given how our heat and UV measurements are going.
Interesting. It appears that it is one side effect of climate change.
Side note: PV panels try to absorb a lot of light. Parasols try to reflect it, which is why they usually have a bright color. Imagine now holding an umbrella, absorbing more energy than your skin/hair would, causing you to sweat even more?
Japan (and I think a number of other asian countires) has a lot of people using them as sun shades. Particularly when we walk a lot and even moreso in the concrete jungles like tokyo
Heck, I live in Canada and with our Summers as they are now it’s becoming a common sight here.
And you don’t think that carrying a 10kg umbrella is unsuitable for this type of climate, when you are already sweating with 500g?
I think it is also a cultural thing, as in asian communities brighter skin is preferred
I won’t comment on the cosmetic side of things, but it is several degrees cooler under a parasol/umbrella and that’s the usual selling point. I didn’t comment on the weight or practicality, either (I don’t actually think it’s practical with the technology we have today). I was pointing out that these would potentially be used in times other than when it’s cloudy as zr0 mentioned.
Umbrellas are used in sunshine and are often called parasols. It’s not a bad form factor, it just seems to have practical limitations, like being foldable and still useful. Love the idea, though.
Japan is ready. Other places can be made ready. It isn’t hard to prepare people for bikes or whatever. Solar panels on everything are potentially a good idea. I only worry that my umbrellas do not last.
Wait til a big gust of wind comes through and shatters your solar panels by inverting the umbrella/parasol.
Some areas still use the for just sun protection. Agree that it would not be a global product for now.
What about parasols
Different device, similar features. They tend to be much larger, making the weight an even bigger issue.
Beach umbrellas are mostly used on sunny days so I can see that.
Have you heard about solar roadways?
:-)
I think there are some test roads in the Netherlands on the bike lane. Roads are used in all weather conditions, 24/7. Umbrellas not. Roads have approximately the same energy yield as any solar panel on the roof, minus the suboptimal angle and minus the road users causing shadows.
If you don’t see the absurd part in trying to put solar panels as a road then I’m sorry I can’t do anything for you 😁. There are exactly 0 practical reasons to do so.
There is nothing absurd about it. Every surface, which is constantly exposed to the sun, should be covered in PV panels.
Yeah, starting with a fucking road and having cars drive on it all the time instead of like, you know, putting the fragile panel on the side, so smart. I hope you’re joking 😂😅 what’s next, at the bottom of a pool?
You know there are transparent materials that can withstand forces of those, that are applied on a bicycle path. No one was even remotely talking about driving over unprotected panels. That’s just a weird imagination in your head. Instead of doing that, you could just invest a couple of minutes into reading what is getting tested already.
Netherland’s Solar Roadway Performing Even Better Than Expected!
You’re just digging the hole deeper.
I bet those transparent material are as strong and cheap as asphalt, and becomes magically clean from tire traces…
Why not put the panel on a stick on the side of the road? Is that not complicated and expensive enough?
Edit: that Netherlands project seems cheap. BTW I have a bridge to sell, interested?
Get a wind powered hat instead
“Rollable” solar panels are still pretty stiff. You would need a beefier mechanism to handle the extra forces required. They also have a pretty significant “minimum turn radius” so they would need an entirely new design for their mechanism to work without damaging the panels.
They do make personal solar array with a surface area comparable to your umbrella idea, but those would take days to charge a cellphone, so the charge you get walking around for a few hours is negligible.
It’s a cool idea, and would be a fun project to build and show off, but it’s not going to be marketable or practical without a whole lot of development in solar, battery and umbrella tech.
- portability
- cost
- efficiency
- return on investment
- market size
I think the umbrella did not satisfy all these parameters enough for it to take off
Probably because it would weigh 40 pounds and cost $1700. It would probably also suck, and break very easily.
And having any of that shit anywhere close to saltwater? Hell no. The electronics should be corroded within a week.
Edit: while we definitely have the technology to do this, we just don’t have the capability to mass produce them at a reasonable price or of any reasonable quality. Current technology and materials also come with a lot of really crappy limitations. Maybe something like this might get developed if a lot of people suddenly show interest in it, but aside from that happening, it could be a while.
Developing a product like this could take hundreds of millions of dollars and 10 years to get something like in the picture above.
There’s plenty of solar panels that don’t weigh a lot these days
Nah. You could DIY something like that for 30€ or something, let alone mass produce. The only problem is that the folding would be more clumsy and probably take a bit more space folded
Edit: picture of a real product from which you could DIY one:
I have 2, around 25cm x 30cm and, when perfectly aligned to a strong summer sun, they do 1 watt and 2 watts respektively. Amazing.
Also, sitting outside in the harsh sun with a laptop? No thank you 😁.
This is really niche stuff for when you can’t even reload your power bank once every couple of days IMO.
Yeah, that’s my experience as well, you leave them out all day and get half a power bank if you’re lucky. Basically only worthwhile if you’re camping somewhere remote for an extended period of time.
I got one to charge my phone to 1%. Pretty happy
Now look at the standard umbrella and figure out if it is 25x30cm…
I’ve got a very similar panel myself, in fact it’s probably a bit bigger.
If you leave it out all day, under ideal conditions, it will put around 10AH worth of charge into a power bank, maybe a bit more, so 40-50 watt-hours if you’re lucky, over twelve hours.
Not a worthwhile amount of power.
Yeah this has always put me off solar panels like this, for their cost they make fuck all and if you just need power for a day or two it’s better to get a battery. Only if you need weeks does solar+battery start to make sense instead.
That charges a phone just fine?
I use a smaller panel to charge a battery at a summer cottage. That keeps my and a few other people’s phones charged pretty alright.
Not worthwhile if you’re carrying it around all day.
Why? You can carry your phone and charge it at the same time.
Why do you need to charge your phone during the day anyway? Does it not last a full day?
Modern smartphones are terrible for energy consumption tbh, if you just want calls/SMS an old Nokia is so much more energy efficient.
I suppose turning the phone off can help save, but how many people could even comprehend that these days?
Slapping one together out of spare parts is not at all the same as mass producing one in a factory.
And whatever you could slap together for 30 bucks would, as I said, in previous comment, suck and break very easily, not to mention that you wouldn’t be able to bring it anywhere close to the ocean for fear of everything corroding extremely quickly.
Yeah. Mass producing can be orders of magnitude cheaper.
It’s a ridiculous argument. Of course something like that could be manufactured, it’s just too niche of a market so nobody has made it a reality (yet).
Lol that tiny ass solar setup ain’t charging both a laptop and a phone, least of all with them running.
That can just barely charge a phone (source - I’ve done a lot of math around this, solar panels have very low output per square meter).
I would think of using the solar panel to charge a battery pack instead, then you can power devices from that. Although you may be charging the battery for 8 hours to power a laptop for 2.
Who said it would?
The picture clearly implies that.
A computer?
There is a cable running from the solar panel to the laptop, implying the panel is charging the laptop.
Which, based on my experience with them, ain’t happening.
Oh in that picture. Yeah I didn’t even think about that, I’d imagine for the original use case you would charge a phone. Laptops need a lot of power, I didn’t even dream of charging one off of a portable solar panel lol :D
The weight of a battery pack sounds unpleasant for something you would be carrying for a long time.
Meh, l stick with analog umbrellas. They don’t need electricity to open or close.
You could use a Sekiro shield: https://youtu.be/OCq8adZdKP4 It’d be rigid but… probably quite heavy.
Is your plan to walk around with your umbrella up when it’s bright and sunny, or to wait until it’s overcast, dark, and rainy—hoping I charge something?"
Maybe a parasol would be a better idea?
Funnily enough, the word umbrella derives from the Latin word umbra, meaning shadow. An Umbrella was originally for protection against the sun. I know it now usually is used for the thing protecting you from rain (at least in English), I just thought it was funny that people did walk around with what they called an umbrella when it’s bright and sunny for a few hundred years.
Get/create a solar backpack with a powerbank instead. That way weight is less of a concern and you can charge it when the sun is actually out without looking like a weirdo 😅
I have had the same idea. Photovoltaic cells are sadly all quite stiff and/or fragile …
The cells don’t have to flex to have a flexible sheet of them. Just attach them strategically to a material more suited for flexing.
For real though, I mean, you could also just use a different layout. You don’t have to use triangles and make a circle. You could have a square umbrella that folds out with a little bit of prodding.
So far. A lot of progress is being made on that front.
Do you usually use an umbrella when it’s sunny or would you do it just to charge the battery? I know it’s a thing but only very rarely see people do that, probably not enough to have demand for something like this. Backpacks with solar panels exist but I think these are pretty hard to find too.
It probably depends on where you’re from, but it’s a thing. In Japan you’ll see people walking with an umbrella to avoid the summer heat.
That’s called a parasol.
I get people think it’s the same thing, but this is a case where words matter.
If someone said “solar parasol” no one would assume they meant the device intended for rainy weather.
Well, umbrella literally means “little shadow” and is aptly used as a synonym for parasol in severeal languages. Just because the English misused them to shield against rain does not change the meaning. Or perhaps it does?
I’m pretty sure Japan doesn’t make that distinction.
This idea is right up there with Glow in the dark sunglasses.
Looks like this guy couldn’t get financed to make something similar: https://www.homecrux.com/solarbrella-turns-beach-umbrella-charging-dock-phone/74666/
– but my search did turn up alibaba results for similar stuff, so they probably just stole the idea from him.
Nitpick: You want a parasol or sunshade, not an umbrella. Umbrellas are for rain (latin origins aside). It is cloudy when it rains.
It would get stolen real quick too, unfortunately. Also probably very fragile or very heavy, and would only be useful for a very specific time of the year only (during very hot summer). No clue how much output that would make though, but I’m gonna guess it’s not going to be anywhere near useful.
why would you have a solar powered umbrella instead of a parasol? isn’t the only difference one is used when no sun lol
also sound like a bad idea either way
