For those who are seriously looking into doing something like this it's not a total waste and results can vary a lot. One of the big things is Amy here lives in a house, a rather nice one by the looks of it. The quality of your windows hurts your ability to get solar power threw them. The more energy efficient they are, with a better glazing to prevent UV rays and all that from coming in the less power you would get. So if your renting out of a crappy apartment with old 1960's era windows you might get better results. All that said this is not a great way to get power even if your renting. You might have better luck putting it on your patio to be honest if you have one. In the very least small panels like these are not too expensive and you'll still have them if you move into a house or even just go camping.
I have a 50W panel sitting in a window right now and it's producing 25W. That's 25W more than I would have as I have nowhere to put it outdoors. I think it depends on what impurities or additive are in the glass of your window, mind are actually double glazed.
50w flex panel in a south-facing Window with cheap double-glazing. ~18 watt charging shows on a BLUETTI cheap power station with the panel flat to the glass, ~28 watt with it tilted back about 30 degrees.
Thanks for the video, it would be great to see your responses to the questions below. Also: what type of window were you testing? Wouldn’t a low E window designed to keep heat in and sunlight out lower your results? What about an old house with single pane glass and a single pane storm window? Same results?
I had an idea to stick a solar panel on inside of some of my windows whilst it's not ideal compared to out doors it would still be sufficent to charge a mobile phone or even a battery bank for emergency power source or lighting
I have a small solar panel taped to my window. I can power a battery operated radio even on a cloudy day. BUT: Only old radios will work on a cloudy day or in the shade. A modern radio will only work in direct sunlight.
Something to Note: Some of the small solar panels to maintain a car battery, are placed inside the windshield, either suction cupped to the window or sitting on the dash. Even though they are behind the windshield they seem to work but at reduced amps-slower. Our windshields are 2 panes of tempered glass sandwiching a plastic safety film. Our modern home windows are 2 panes of tempered glass separated by a pocket filled with an insulating gas.
I only use the panels right against my windows. Got some BIG windows. Lots of theft (of panels) here by us. My 200 A solar panels have the right voltage, but only output 7.1 A (it is winter now) with direct sunlight on the windows. I THINK I should be getting 20 Amps?? But st least my panels does not get stolen.
Had three panels in window (10w x 3 in parallel), was getting 17v @ 0.6A, then I brought them outside, 20.75v @ 1.55A.... So yeah, a third. or 33% inside at 10+ watts, and 33+ watts outside. Indoors in a window is not recommended. Great video. Thanks.
I light my whole house at night with low light, low voltage, LED from photo-voltaic cells in the Low E windows. I only use 1 AA rechargeable cell for each homemade device and Three 1 X 1 inch photo-voltaic cells inside Low E windows. I have a voltage drop of only 0.07 in 8 hrs, lighting eight 3 V. LED. ~~~~~~~~~~~~~~~ I don't have to turn on any lights to walk around at night, or if I have to get up in the night for a bathroom call.

I’m surprised this isn’t more popular. Placing panels inside is right at the threshold of what I’d expect most property managers to ignore. I’ll take 1/3 amperage with large south-facing bay windows in the California sun. By her logic, solar isn’t viable he most regions because of clouds.
That was a really helpful video. I'm writing from India. We have a West facing balcony where we receive sunlight from 12pm -4pm in winters and 12pm-6pm in summers , would it be any good if we install a solar panel outside the balcony facing the sun directly?
Hi Amy. Firstly thanks a lot for your interesting videos. I have a question for you! What if I have one of the solar panels placed outside that is affected by the shadow of a neighboring wall. Can I place and use a common mirror to redirect the solar light to the panel? Can you show us how (in)effective this would be? thanks a lot. :)
It was also interesting to watch the current as different parts of the solar panel were shaded as the author reached across the panel. With the shadow going horizontally the current dropped to about 2/3 of the max, not great but liveable with, but with the shadow going vertically the current dropped to about a hundredth of the max.
Very good video. I left a like. One can install solar panels in a window, but if the light is not directed right at the panel, then the current (A) will be low most of the time.
I am running a 100w panel in my window. It is leaning back on to a pull-down shade. It pulls 50w and I just bought another one to go next to it. I checked the temperature of the panel and it is 120f. my question is I don’t want to start a fire. How hot is to hot.
If you put solar panels in the window. Go parallel with the panels wattage will drop too much in series as the current drops already in series and it's against the window
That is commonly done with cars that are shipping overseas, just to keep the battery topped off a little. So it depends on what your goal is. Keeping an unused car battery topped off with a little power, or trying to make enough energy to use for other things. It also may depend on the glass of the windshield, if it have UV blocking capabilities. As you saw, I did get some power from the panel, so it isn't completely blocking it. Maybe I'll do the test again with meters that track how much energy I make throughout the day for a better comparison. As other commentors have noted, they are doing it and making it work, but with greatly reduced energy.

I have solar in my window with fabulous results, I use them to charge my 4v 17,5Ah ebike battery, I charge my 12v walmart deep cycle battery and run an inverter off that to charge my Greenworks 60v battery, with the 60v battery I have lawnmower and trimmer(weed wacker), leaf blower and snow thrower. with my AIMS 48v 1500w pure sine wave inverter I use 3 60v batteries in parallel to run the laundry machine and dishwasher. I have one 40w and one 50w panel in the window at all times except on nice days I take them out on my deck and get full sun on them and add a 100w panel to the system. I could leave them outside but I think they will last longer the way I'm using them.
+Chris DIYer I've seen several different solar windows. I think they are a fabulous idea, being translucent they don't block the view or the light from getting inside. As a result, they are very inefficient, requiring a lot of windows to generate much power. Hopefully they can get the price down to a point where it makes financial sense. Exciting times we live in.
In a seasonal cabin when snow covers the outside main panels, would a indoor small panel directed in the sun be enough to keep the batteries from draining and freezing? The main panels are snow covered most of the winter and I have four batteries that need to be maintained.
I live in an apartment. And the sun raise up in east in my living room and moves on around to the side bedrooms by 12 am but once ite sun comes around to the back , the shines the longest on that back bedroom. I call it my sunroom. I can set up the solar panel on the side of the apartment where the sun moves around by 12 o'clock, but sunroom ( the 3rd bedroom) seems to hold the most. My are 100 watt solar panels but would only be able to set 3, though I have 5. I don't know how this will work. The panel you had looked small. Is someone I could call to ask questions? Thanks
Under exterior sunlight, the 960W reading is 96% of the 1000W. The short circuit reading felt far shorter than that 96%. Is the manufacturer misleading?
The ratings of the solar panels are under standard test conditions (STC). That is with perfect light and angle and temperature, etc. That allows all manufacturers to compare and rate their panels apples to apples. The rated power is the Vmp x Imp. Real world installations will likely have different reading for less than ideal conditions.
I see what you are saying, there's sort of a reflection of me on the panel. So even though I wasn't directly in front of the panel, I was causing some reduction in power generation by being beside it.
I do think this demonstrates the fact that you're trying to relate to everyone. there are a lot of different ways to reduce the overall output and dramatically reduce the efficacy of your system. good video series :-)
The title is misleading. You never installed the panel against the glass. You highlighted what you wanted to talk about instead of sticking to the title subject and showing actual results IN THE WINDOW.
Thanks. very helpful video . I bought 2 panels 50 watts and 60watts and before a small 10 watts for test [ without making until now any test] 3bulbs and put it inside my window. now you prove me that inside the apartment[ [ because on the roof is possible to steal it somebody ] is wrong.please tell me can the outside on my balkoniy moisture and the drops of the rain damage the cells and the others instruments behind the panel. I am waiting your advise. thank you .
Everything that I checked into states it's not really worth it. Double pane windows over the surface of the solar panel decreases it ability enough that I chose to do it. I'll place the panel on the outside, and run the line into the rooms I plan to use solar.
Here in great Britain we have these godawful pvcu panels below main window area the council could replace these with suitable sized solar panels that are also insulated maintenance free weather proofed and wire them into each flats electrical circuit there you go would help a tenant save heaps
First of all these panels are NEAR the windows, not in them. And, a panel can be installed in a window frame without the glass, which takes care of the glass problem.
The only important comparison was 0.55A inside, and not very close to the window, vs .78A outside. When she was inside, she compared against the theoretical maximum, bu she couldn't get anywhere close to it outside. The voltage also dropped by 10% so wattage would be 20x.55 or 11 vs .78x22 or 17. 64% as much power inside vs outside. Additionally, the sunlight probably will not last as long, though the morning and afternoon probably don't provide that much more power. So call it 50% efficient or 30% of the rated power. In a high price area, where power runs .20 cents per kilowatt hour, if you can get a 330 watt panel for $290 and add $610 for shipping, charge controllers, inverter, batteries (one per 6 years), you'd be looking at $900 and get .4 KwH per day with 4 hours of direct sun at 100 watts per hour, saving 8 cents per day x 365 = $28 per year. That's breakeven in about 30 years assuming power prices never rise. That's about the life of the solar panels, so doesn't save you any money unless power prices rise, but it doesn't cost you anything either, other than time. However, if you have need for a backup power supply, for example due to hurricanes or the like, two panels will keep your laptop, tablet and phone recharged, and your network equipment running indefinitely (assuming you can reach your network provider), and this setup doesn't appear to actually cost you anything more than you'd pay for the power itself. You can skimp on the solar system battery because you can just recharge the devices when the sun is shining if you can get about a day's use out of their internal batteries. All in all, it's worth having a system that will work for a few days after a storm and keep you connected for business at no real cost to you provided you use the power you generate in some way when not in an emergency situation.
It's always a good idea to get different opinions. Here is someone who installed solar panels 9 months ago. He feels the benefits far outweigh the cons. ruclips.net/video/2rCKYm1BJYY/видео.html
that's just 1 solar panel window tho... but if their were more of them( like all the windows u may have converting energy ... 100's more (for big buildings) connected to the same conductor then maybe🤔🤔🤔
You can probably still make a little power during the peak sun exposure each day. Only about 1/3 MAX of what you could get outside but potentially enough to recharge a solar generator, especially over a few days!
this doesnt answer the question, measuring form inside the room is obvious your not gonna get the power you need and why would you have a big ole solar panel sitting around in your room? I want a solar panel installed directly in front of a sunny window. It might not be as good as OUTSIDE but OUTSIDE is NOT an option for me. I need to know if My idea is doable. Not only that, I plan on using it with batteries. So the battery is going to store WHATEVER is going in. Then I can use my deep cycle battery as needed. Is this doable? Thats all I want to know.

50w flex panel in a south-facing Window with cheap double-glazing. ~18 watt charging shows on a BLUETTI cheap power station with the panel flat to the glass, ~28 watt with it tilted back about 30 degrees.
The amps sure drop when the shadow from your hand crosses the panel. A good way of showing how even the tiniest bit of shading drops the output.

Great video, was hoping you actually stuck a panel right up against the inactive portion of a window. For us renters
A foot back she got about 1/3 so right up against it probably .5 or more.
I had an idea to stick a solar panel on inside of some of my windows whilst it's not ideal compared to out doors it would still be sufficent to charge a mobile phone or even a battery bank for emergency power source or lighting

Sun Shine I agree. The Isc reading is really low. Actually, in the video one gets the impression that the panel is affected by shadows...

Solar panels have no problem outside in the rain. But the charge controller, batteries, and inverter should be either inside, or in a rain proof box.

Wouldnt a mono panel be more efficient
Everything that I checked into states it's not really worth it. Double pane windows over the surface of the solar panel decreases it ability enough that I chose to do it. I'll place the panel on the outside, and run the line into the rooms I plan to use solar.

So that solar panel collects 11 watts per hour or 16 watts per hour? doesnt seem very effective.
amorphous cells work in awindow...
I would set it up inside with a desk lamp shining on it.
Wouldn't generate. U would be cheaper using lower wattage led lights & saving the power
What if, you had an outdoor solar panel powering a sunlamp which is directed directed at another solar panel... Indoors
It's only putting out amps because you're sunny Amy.
try bifacial monocrystal panel
3:30 freeze don't move
i saw that 😂😂😂
Yes
Whatta Bummer🙄. I am trying to figure out if I can solar in my city apartment to work hand In hand with a solar generator 😳
You can probably still make a little power during the peak sun exposure each day. Only about 1/3 MAX of what you could get outside but potentially enough to recharge a solar generator, especially over a few days!
This guy told me he hangs his panels outside of his window to charge up his battery pack...
this doesnt answer the question, measuring form inside the room is obvious your not gonna get the power you need and why would you have a big ole solar panel sitting around in your room? I want a solar panel installed directly in front of a sunny window. It might not be as good as OUTSIDE but OUTSIDE is NOT an option for me. I need to know if My idea is doable. Not only that, I plan on using it with batteries. So the battery is going to store WHATEVER is going in. Then I can use my deep cycle battery as needed. Is this doable? Thats all I want to know.
I love your bangs
Your title does not match your demonstration.
what size solar panel did you use in that test?
I think it was a 30W panel.
And there is the disappointing answer to my question.
oh sorry I see the Reverend and already hit on that
🤔
