Putting iTechworld's 300W Solar Blanket to the test ⚡ 

Yea but concerned that old mate making the video has no idea what he is on about and spreading false information at 12v this thing should be pumping 25 amps ramping down to 21 amps when charged at 14.4 volts

Yea don’t think he has any idea what he is looking at

Any suggestions on what panel to buy Cheers

The 16 amp is a reference to the current from the panel to the charger. The voltage the panel should deliver this to the charger at is about 19v. 16amps x 19v is your 300w rating. The solar charger should convert the 16 amp 19v to anything from 12v 25amp to 14.4v 21amp. The product is not performing as advertised

Like everything itech sells mate. Love the videos Dan and Bianca put out and would never criticise them but itech gear is crap…

They get it for free we pay $799 they have to say it's great good if iteck can comment about the product on he and show how it's 300watt not just by sticker on the back invite them on 🤔

He is taking the reading off of the 12v side of the system after a loss of efficiency going through the DC to DC charger, also solar panels work their best in cooler temperatures. So if he tested the voltage and amps at the solar panels I'm sure he would have 18V and 16A or possibly less because the panels are hot.

@@KurtisPape The panels should be putting out 300w OR MORE as other brands do. This is regardless of the solar side or the battery side. It maxes out at 215w when through the MPPT. If i was getting 215w from a "300w" panel well mate, ide be wanting a refund. Rubbish!

@TV Photography good luck putting solar panels on your house and actually getting the rated power, even in optimal temperatures. A 5kw solar system will never put out 5kw, your lucky to get 3.5kw in optimal conditions.

I have a Hardkorr 2 panel portable Crocskin unit I bought a few years ago, it works very well and if you accidentally walk on it it won't break. Can't remember the wattage but it provides 6 or 7 amps in direct sun. It beats a mate's cheap Kings one that's twice the size :)

150 watt cost Usd 349 ,kind of expensive,there are more good choice than this,l am professional producer in this line，Knows their price and power better than anyone

Don’t read the wattage when buying panels, it’s the maximum amp specs you should use when calculating

If you went to the petrol station and paid for 300L of fuel and they gave you 215L would you consider that a good result?

@@biancaspice6409 beat me to it. good reply

@@biancaspice6409 You are so confidently incorrect about this as someone else has pointed out in the other thread. You should probably consider editing or removing your comment which is misleading.

@@andrewford80 edited. But just FYI, there’s nicer ways to say what you’re saying. Keep that in mind in future please 😊

@@biancaspice6409 it's a challenging topic right up until it makes sense and the importers and others keep it that way, the other explanations were really good and there will be lots of learning in this topic for plenty of people reading it, well done to all involved in the production of the content for not shying away from it.

Thanks Simon! I'm yet to do some proper testing in partial shade and cloud cover but will report back when I do. 🙂

But they don't put out rated output. Supposed to be 300w, but it's only 2/3 of that. That 16A is at a lower voltage, resulting in way less than rated power. Are you on their payroll?

Ye but $799 you think you better

Don't no if it hate or just want manufacturers to be honest about their products

A 160 amp battery would take 10 hours - it's very simple maths. Your turn - your 100AH Lithium good quality battery is at 68% charge - how long will it take to charge?

@@einfelder8262 oh oh I got this hahaha

Hey mate, all readings after the MPPT solar regulator are right there on the screen so no guesswork neccesary (see 2:06). 13.37V, 16.05A, 215W. Keep in mind compact solar blankets aren't as efficient as solid panels (the price of convenience), and these have outperformed quite a few others I've tested.

The 13.5 is the battery voltage not the panel. The panel is supplying 16.1 amps 215 watts so the voltage must be the same. If it was higher say 15volt 15vx16.1amps you'd be getting 241 watts. Anyway good luck with it!

It seems that the misinformation is not a fault with the 300W output from the panels themselves. The stuff up is with the description that it is a 300W "kit". There is no way known for a "PWM" solar charge controller to convert the panel output into a 300W charging current, as the PWM unit just clip the panel voltage off at the required charging voltage and waste the rest of the panel's power.

I disagree to an extent. Some manufacturers out there bench mark their solar panels to 1000W/m2, iTech by the looks aren't one of them (I think hardkorr for instance do). The most the sun can produce in perfect World conditions is around 1365W/m2. Typically, these mono cells in thin layer form such as I'm blankets are around 10-11% efficient as opposed to their other forms such as glass panels at around 20-23% (a lot of companies state "up to 23%" which is a generic value for quality roof top stuff). Since these panels are around 2m2, you can expect an output of around 220 to 300W depending on ambient conditions I.e. temp, time of year, lattitude/angle, etc.. with the 300W unlikely (2*1365*11%= about 300W) or more like 220W bench marked against a more reasonable 1000W/m2. They look nice, but I think there is better value elsewhere given the $799 price tag. That's my opinion anyway, quick calcs based on area are telling me 220W is what to expect.

Absolutely not, the only comments that have ever been deleted on this channel are either those left by scammers trying to get people to contact them, or comments left by myself. I’m disappointed to read your recent comments on various threads implying I “have to say it’s great” about products I review which is blatantly incorrect. I make it quite clear in each video that I only agree to providing honest reviews, turning down any companies that don’t agree to these terms.
