Ken Fujimoto's solar report A solar generator that can be rolled and carried I tried using "Emergency Disaster Set of Power generation anywhere"

　I want to have a solar power generation system as an emergency power supply for an emergency.However, very small ones are useless, and those with reasonable outputs are expensive and cannot be reached.Also, if it is large, there is no place to keep it.

　Meanwhile, I found a product I was interested in.It is a product called "anywhere Power Mobile Solar Unit" developed by OS and sold at Yodobashi Camera.This is to generate electricity in a film -shaped solar cell, and when not in use, it can be wrapped and stored in a compact state.

　This time, I had the opportunity to use the "Emergency Disaster Set GSR-111B-S1", one of the power generation series, so I tried it immediately.

■ I usually store it, pull out solar cell seats only when used

　The GSR-111b, the main unit of the emergency disaster set, has a red aluminum, elongated box-like shape.510 x 85 x 110mm (width x depth x height), weighs about 2.8 kg, so it is compact so it does not get in the way.Since it can be placed vertically, it can be placed in the room corner.

　The solar cell is film -shaped, and when you pull the handle, it comes out from inside.It looks like a slightly thicker leisure sheet rather than a film.

　I couldn't help spreading it in my house, so I took it to a sunny park and stretched it.The length of the pulled seat is about 1m.Like the vacuum cleaner wrapped code, pull it down once and release it, and it will be rolled up.In addition, the center is curved in a form that makes the center slightly a valley so that the seat does not roll up with the seat extended.You can bend it quickly (don't bend too strongly).

　The color is dark blue on the front and whitish side, and can generate electricity by pointing the dark blue one to the sun.

　But again, a sheet -shaped solar cell is a unique idea that breaks the concept of "solar cells are a hard panel -shaped thing".This solar cell is so soft because it is a thin film solar cell.It is not a single crystal silicon or multiple crystal silicon panel on the roof of the house, but is an amorphous (non -crystal) silicon solar cell used in calculators.Amorphus Silicon solar cells have the advantage that power generation efficiency does not decrease even under high temperature conditions and can be manufactured relatively low.On the other hand, there is a drawback that power generation efficiency is lower than that of crystal silicon solar cells.

■ In addition to solar cells, a rechargeable battery is also installed

　In addition to this solar cell sheet, this product has a built -in nickel hydrogen battery.The major feature is that by charging the battery with a solar cell and using the power, it can be used even if you take it home at night.

　The battery capacity is DC12V 2.0Ah (about 20WH).In theory, 20WH can be used for 1 hour if a 20W device is connected, and a 5W device can be used for 4 hours.It doesn't mean that you can move a very large device, but it seems to be usable enough to charge your phone, put on a lamp, or ring a radio in case of emergency.

　This product also comes with an AC adapter.You may wonder why the solar cell is an AC adapter? However, it is used to ensure that the built -in battery is charged as preparation for emergency.

　When the battery is charged, the LED lamp is lit in three colors, green, orange, and red when the button is pressed.When it arrived, it was green and full charging.

■ There is no problem with charging the attached LED lantern or USB.

　Now, how do you take out electricity from this body?The only outlet is the cigarette socket on the main body.There is a feeling that it is difficult to handle, but it may be convenient for versatility.

　This product includes rechargeable LED lanterns, USB hubs, and mobile phone charging cables as accessories, and the rechargeable LED lantern and USB hub have a cigarette socket.

　Immediately, when I connected the LED lantern, it turned on without any problems.The lantern side also contains four nickel hydrogen batteries, so the LED shines while charging it.The lantern side can be used for about 50 hours with full charge, so it is likely to be reliable in case of emergency.

　The mobile phone charging cable is a set of four types of adapters, such as NTT docomo and au, and is used by connecting to a USB hub USB connector.Here, when I connected to the au feature phone, I could use it without any problems.

　USB should be able to connect to the iPad, so I tried it.Previously, when a small solar cell was connected to the iPad, it was not possible to charge due to lack of power, but as expected, there was only a 20WH battery, and the iPad was able to be charged firmly.It seems that it can be used without any problems as a USB connection power supply.

■ I also wanted to use the optional AC100V

　If you know that USB can be used properly, you will have a desire to use the AC100V instead of a home outlet.From now on, I decided to try using the DC-AC inverter "G-A04", which is an optional product, up to 100W, to use AC100V.

　I thought it would be convenient to use a notebook PC, and when I connected my favorite laptop "VAIO", a problem occurred.From the main unit of the GSR-111b, an error sound was heard "Pee Pee".Looking at the output voltage of the inverter, you can go around 90V around 60V.Apparently, the voltage drop was occurring due to the output.

　When I checked the manual again, the maximum output was 20W.I thought that it would not eat so much because it was ATOM's low power VAIO, but it seems that the power consumption was about 35W if the power was turned on, so it was over capacity.

　So again, I turned off the VAIO power and just charged it, and I was able to charge well without the error sound.

　This time, I connected an LED stand with a smaller power consumption.There should be no problem because the output is 9w, but this also happened.It certainly turned on when the power was turned on, but when it was turned on for about 5 minutes, it still had an error sound.A voltage drop has occurred.If you use the light, it may be safer to use the included rechargeable lantern.

■ Power up the output and capacity when connected

　Another feature of this GSR-111B is that the output and battery capacity can be improved by connecting.

　The body can be connected up to six.If two connections are connected, the battery capacity is 40Wh and the output is up to 40W.If it is three, it will be 60W with 60Wh.The connection method is easy.Just connect the output from the cigarette socket to another AC adapter connection terminal.

　In addition, there is no solar cell, and there is also a battery-only unit "GSB-01" (17,120 yen for Yodobashi Camera).The capacity is 2.0Ah (20wh), and by connecting this, more electricity can be used.

　This time, I connected the VAIO above with two GSR-111B and one GSB-01 connected.However, after all, it could not be used with the power turned on.Here again, if you use it while charging and generating electricity in the sun, it will be successful this time.The output voltage of the inverter is also stable at 98.5V.There are some questions about whether the inverter should be used so far, but the power of the sun was felt again.

　As mentioned above, I reported on a sheet -shaped solar cell called "Power generation anywhere", but how was it?After all, compared to crystal -based silicon solar cells, I am worried that the output is small, but it is a great advantage when I think that it is an emergency power supply to be able to wrap it around.Removing the AC100V seems to be an option, but there was no problem as a USB connection power supply that charged lamps and mobile phones, which are basic performance.I felt that there was enough use to surpass the emergency.
