Cheap VS Expensive Solar Panels | 12v Touring | Project Cyan

Looking after your deep cycles batteries that you spent so much money on is important to ensure a good life span, solar panels allow you to keep them constantly at full charge while your touring.
Are expensive solar panels worth it? is there anything wrong with using cheap solar panels?
In this video I test a cheap solar panel from Sunyee and a expensive panel from a local store called Itechworld. Also in this test we see if having an MPPT solar regulator is really does give your more amps over a PWM regulator.

This panel can put out close to 100 watts kzbin.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.

The problem is not that the "cheap panels" are always nasty - you proved some are not - but the expensive panels can be just really cheap panels with a brand name attached and huge mark up. It's not that I don't trust the cheapies - you get what you get, but I don't trust the pricey ones - maybe it is a good one, maybe its not, yet you pay through the nose - *you can't judge by the price.* What a great review Michael!

[@hughleyton693]

The best, and simple way to check the best Solar Panels is to measure the Open Circuit Voltage and the Short Circuit Current. Now take 80% of the Open Circuit Voltage multiplied by 90% of the Short Circuit Current, to give you the POWER The Open circuit Voltage should be fairly consistent regardless of how much sun or cloud there is. It is the Short Circuit Current that is the all important one that varies with how bright the Sun is. Good panels will give you more Short Circuit Current under identical conditions. Divide your power by the surface area of your solar panel in square meters, to get the Power per sq.meter. These should be around 16% to 18% efficiency from the actual Sun's energy on your panel. Full Sun on a cloud free dark blue sky around midday should deliver about 1,000W. So at 17% efficient, you could get 170W. Quality may then simply come down to how long they will last. Solar Panels can last 50 years or more, if looked after and protected from damage.

[@Smickster01]

i had a mate who likes his solar panels too, and he was always doing tests on his camp gear to get the best out of cheap stuff. he also had expensive panels that were outperformed by some cheaper ones. one of his under performing panels was also a gloss coating resin and very shiny. we brainstormed all we knew about solar panel function (this took all of 5 minutes) and decided we were going to modify the expensive dud panel as it was worthless due to cheaper better lighter panels. SO, we made a wood block as wide as a sheet of wet and dry 1200 grit. we dragged the block and wet and dry in straight lines up and down, very evenly over the entire panel (just enough to see light scratch marks in the gloss, then same again cross ways and more difficulty, both diagonals also. it looked dull and matt finish and the resin coating was quite white in appearance as the scratches would look. we then re polished the panel with car polish to smooth it back a bit and noticed the car polish also made their own scratching and visible swirls. then it looked just old and worn and scratched....BUT, when we tested it a few weeks later against another identical panel that was still high gloss finish, the scratched resin panel was more efficient than the same one without the scratching. turns out that the scratches allowed light to be amplified by the mirco scratches (possibly somewhat like very small magnifying glass) and we think this has increased the actual surface area of the glass coating while not disrupting the actual size of the cell and thus more light reflected and refracted thru the glass resin gloss coat at surface level. we werent sure if this was an anomaly so he spent a night scratching up his other identical panel and again when we tested them together, they result was the newly scratched panel also increased its amp rate to almost the same as the first scratched panel. he has told all his camping mates and he was shouted down. til one of them did it and improved his old heavy gloss panel. id love to know if anyone else has had similar results

[@rastanot]

I'm not an electrical engineer, but this makes sense to me. A glossy surface would reflect the light away from the panel. Where as a matte finish wood absorb ions more efficiently.

[@Smickster01]

@@rastanot yep, i think if the panels are too scratched then you lose performance, but there definitely is some gains with the correct grit scratching. im sure if somebody tested different grit such as 600 grit or as fine as 1800 grit, there will be an optimum grit that actually goes closest to optimum without going over and degregating the performance. but for sure, light scrapes evenly with 1200 improved the performance. i spoke to him last night, he has solar panels on his home and although he wont scratch them due to warranty, he said he does use cut and polish to clean them. he said there are visual swirlmarks on his rooftop panels but you cant see them unless your looking for them. i think there is definitely something to this for extra efficiency.

[@itisriley]

As soon as I saw the reflectiveness of the $300 panel compared to the $100 panel I immediately thought, as long as there is nothing wrong with the cheap one, it will work much better.

[@ericyoungren582]

Great video! I love your enthusiasm and your solar powered lifestyle. PWM controllers still provide three-stage battery charging for lead acid batteries (bulk, absorb, float). They just operate at the battery voltage rather than the MPPT voltage of the panel. In a hot climate with short wires like you have there will not be a huge difference in the charging performance between the two different controllers. The added benefits of MPPT style controller are most evident where the temperature drops below freezing and/or where you need to make a long distance wire run and connect multiple panels in series for higher voltage and lower current in the overall circuit.

[@fratermus5502]

A couple more edge cases where MPPT has an advantage due to the Vbatt = Vpanel issue you correctly mention: * when the batteries are deeply discharged * when using relatively low voltage charging setpoints * when running loads larger than the panels can support at battery voltage For curious/geeky onlookers, I'll note that even MPPT do not always run the panels at Vmp: they run the panels at the voltage required to [try to] meet demand at the time. Sometimes that's the MPP, sometimes it's not. :-) Even where MPPT has advantages, the much higher cost of MPPT may not be worth the return for a given scenario. It is commonly said that many folks would be better off with PWM + an extra panel instead of spending that money on MPPT. Horses for courses and all that.

[@notyoung]

Someone asked about solar panel output in reduced light. On a rainy day, a 250 watt Jinko panel puts out about 20 watts. These are panels that produce a measured 235 watts in full sun. Low light performance doesn't track between different panel sizes or manufacturers. On the same rainy day, a 30 watt Aleko panel produced just over 1 watt. The Jinko panels keep my "Wait until daylight" solar generator charged so we'll have limited power when commercial AC is out (several times each year). Depending on the season, we have 10 to 24 hours of limited power with no trip out in a thunderstorm to set up a small gasoline generator. The most recent use of the solar gen was having 7 inches of "1/2 to 1 inch of snow on grassy areas" and the power out for 12 hours. We had furnace, fridge and some lights after a quick trip to the basement to operate a few breakers.

[@notyoung]

Followup - on a series of very dark and dreary days, the output of two 250 watt panels was 5 watts or about 1% of their rated power. Solar power does require solar input ;-) For my application - keeping a battery bank charged for use as a solar generator when commercial power is out several times a year, but usually for just a few hours - days like this are not a problem unless they're accompanied by ice or winds that can bring down power lines. The solar generator provides 10 to 24 hours of limited power, depending on the season - obviously there will be fewer hours of power if the central heat is running ;-) However, the solar gen does provide "Wait until daylight" power so I'm not out in the dark or a thunderstorm getting a gasoline generator going. I've done that - in the dark, in 7" of snow at 30F - so I prefer even limited power (fridge, furnace, a few LED lights, charging cell phones) that doesn't require a trip outside. No, I'm not rich. Just an old guy living on a fixed income and trying to make things easier on myself. The solar generator was financed by proceeds from my first novel, available on Kindle for just $2.99: www.amazon.com/dp/B01LVU5ILA

We should all learn a lesson here. I think it's clear there's a lot of people who still regard products made in China as inferior, but the reality for most of living in Western countries is that practically everything is manufactured somewhere else, with a major portion of stuff being manufactured in China. For instance, in my part of the USA, it was known world wide for it's fine furniture, but all of that was literally shipped over to China, including training by the wood working shop masters. I saw a video recently of a guy in the USA and he was really racist about Chinese products.. wanted to buy American made so he paid a lot more for solar power equipment from an outfit in the US state of Colorado only later to realize it was the same Chinese product that he had decided against because it was so cheap compared to what he thought was the original product, that he thought it was a knock off. Whether or not you agree with the Chinese political system, it must be admitted that they now produce high quality products at very competitive prices. Sure there are scams but we just saw in this video that buying from your friendly local supplier is no guarantee that you're not getting ripped off.

200% mark up is a lot to pay for what you just described. It doesn't have to be this way but I found at least here in Australia that our retailers have no issue at all fleecing the general public to make a buck, especially with relatively niche things like solar for camping. Jump on the Jaycar or BCF websites and compare their prices to eBay for same spec equipment. They deserve to fail charging up to 3 times the price of eBay for the same "made in China" stuff. Also keep it in mind that they get this stuff way cheaper than you or me can get it on eBay as they import it by the container load. I'm happy paying up to 30% more than eBay to have it my hand right now and support local retail but their incessant greed means that more often than not that simply isn't an option .

@@protonpillpopper1 Try running a retail operation before you throw your own prejedices onto a comment board. My guess is you're a wage earner that has no experience at all of paying either staff or commercial rent.

You need to come back!!!! We really miss and appreciate your hard work.

Great comparison, suppressed me.!!

[@mountainconstructions]

Mate, you have the best Solar and 12vdc vids in AU! You're a sparky or auto elec or similar, its nice hearing from like minded knowledgable people The only thing i would add, is some of these cheap panels preform cheap when new, but do this test in 12 months and tell me hows it going Ive seen cheap panels drop by 50% in 12months or less

Glossy finish is reflecting precious photons

[@nuarius]

that was my first thought. as soon as he compared them i was like "why on earth would you make a reflective panel. that's the absolute opposite of what you want"

[@MiguelMartinez-hm9wk]

Robbie Callaghan actually, you can get a better output if you put an anti reflective coating above the solar cell. It may look reflective in the visible range but wherever the cell is most effective, it can increase the amount of photons transmitted through the material. Not sure that that’s what’s happening here but definitely not possible to say that it definitely makes it less effective.

[@uggima1]

There's also the issue of different number of cells and therefore voltage between the panels, but the different voltage shouldn't make up for all the difference in current. Although hard to tell without more information

[@jamescooke3763]

@@uggima1 who cares about the different voltages and current at that end, it's what goes into the battery for your money that matters.

The trick is to do a flex test first and almost break the thing. That's called "breaking it in". That's why it works better.

[@SiriusSolar]

I noticed that attempts to break them first. LOL. His intelligence is amazing. He cuts off the waterproof connectors then mounts connectors in a splash prone area. Does test without mentioning watts & on a battery that's already over 90% state of charge and probably in absorb mode.

Thank you for testing. Now we know which one is better. Please test more solar panels.
