This panel can put out close to 100 watts kzitem.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
It would be interesting if you measure the total capacity of the bank using your static DC load after it is fully charged and see how close the total capacity meet their specs. Thanks.

Check the weight of the capacitor. tap it with a pencil or pen or small metal object. If its hollow you will hear it. My 100F samwha brand cap is for sure 100 farads. Lasts as long as two 200mAh NICD's in series when i'd test both of them in my battery powered drink mixing cup. Has even more power too! MAYBE even longer. Impressive and for sure it's 100 farads AT LEAST. And when its charged up to 3.5v like i've done a few times. It lasts for ageeeees I had a 2 farad 16v capacitor and it could barely power a motor for longer than a few seconds. It you could hear and see the motor slowing down quite noticably.. Now this 100 farad capacitor running the same motor. Just kept chugging along and the voltage barely dropped at all. If they feel excessively light or feel/sound hollow. they might be fake. if not. they could be the real thing. You could test by trying to crank a car engine with these. It should give at least 1 good second of full cranking power and start the car successfully..

You should play around using less in series and using buck converters. That's what I used to do on my solar panels. Instead of wasting 36 cells in series I did 10 in series. Paralleled 2x 10 cells with it so I effectively had 10s 30p and boosted up the output to charge my 12v appliances. Re arranging around a 100w solar panel instead of the 5.29A I usually get on a 100w panel with the new arrangement and a buck converter I was getting the same voltage but instead I had about 15A. So same cell amount. Different arrangement. Better output. I don't know why all major companies don't do this

Hi Julian Nice Video Your style encourages me I think, heeding the safety warnings in comments here, you do need to push the volts. Stored Coulombs go up with the SQUARE of voltage, so overcharging the capacitor pays dividends provided it can be demonstrated to take the charge "safely". Everyone is quick to jump to a conclusion that this cap is faulty, but in fact it might just be that this is perhaps a cap that is from a superior rather than inferior batch. Where is this going? You are not explicit in this video about what your thinking is regarding storing solar PV energy, but I am thinking (a) that the conversion of low voltage at the panel array location, to a higher voltage for transmission to the grid or battery storage location makes a lot of sense when cable costs are considered and (b) RGHxFTW is on the right track...

I looked up the date sheet on these green cap Supercapacitors and it said there is a 20% tolerance so 400 Farad is within that. They all held there charge for a good amount of time except for One. I told the seller about it and they agreed to refund me $8.00 for the one bad capacitor that self discharged rather quickly. There was another one that was not as good as the other four but decided to leave it. I ordered another brand capacitor to replace this bad one. I feel it is a crap shoot when ordering these. I know those small black 120 Farad caps you can buy in a module are all junk the one I bought self discharged to 1/2 voltage in less than an hour. Mr. Julian uses one in some other videos.

Clive just likes to invent problems in his head to call something BS, this is why he has never invented any circuit or isn't the designer of any products, because he doesn't actually know what he is talking about 90% of the time. You could give him the most advanced circuit from Japan and tell him it was from China and he would start thinking that it's shit and make up strange reasons for his belief. He is a joke, sorry.

Of course one would need to efficiently convert voltage for example to 48V(/5A) for a typical motor (just a guess) and be able to do so even when voltage drops from that 6*2.7 (16.2) towards zero as i think it does with capacitors.

hi julian , can you tell me what dc dc regulator you are using here. it seems to have a battery protection circuit. perfect for my project. greetz

I read in my instructions on the ones I purchased you are suppose to charge and discharge these several times before using...

you are probably going to melt that DC connector if you decide to discharge to something large.

Could just be the tolerance of the resistors in that particular protection circuit. Check them!

I wonder if these are the same caps that are used in the sealey super-cap car battery booster pack?

You need to do something creative with those caps mate.

The protection board I bought had a Led already. The balancing of the Supercaps is usually quite off until they are all up to 2,7V. Interesting is that this only happens when I charge them with my powersupply set to 13,5V for a 5s configuration. When I charge them with a 5W Solar panel (18V) The individual capacitors are charging much more evenly right from the start. Surely the Caps are charged much slower but I have no idea how the can allign their voltage other then "burning" energy when the protection kicks in (which happens rarely with the 5W Panel)

What would you need to use one of these with 2Kw solar?
