    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 informative video. I'm able to get 137 watts in the winter from two bifacial 24 volts 200 watt each panels placed inside the house. The windows are double insulated glass and there's a net on half of the window. I've noticed that when the panels are placed right besides the glass of the window, they produce maximum power. Also, since they are bifacial, placing a mirror behind it helps bump up power to 150 watts. Removing the net increases the power further.

    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’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.

    So yeah, a third. or 33% inside at 10+ watts, and 33+ watts outside. Indoors in a window is not recommended. Great video. Thanks.

    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.

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.

    • @AltEStore
      @AltEStore  7 років тому +1

      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.

    • @AltEStore
      @AltEStore  7 років тому +5

      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.

    @charlesgotlieb773 2 роки тому +2

    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.
