Thanks, Hobotech! Just ordered the panel via your link from BougeRV. Been eying the panel, but couldn’t justify it being so far over the $200 mark. Your promo code made it a great deal. Keep doing what you are doing!

[@jasonbroom7147]

The prices on solar panels are plummeting throughout the industry, due to much higher financing costs for folks who might otherwise have installed residential panels on their home. This increased cost has created a huge glut of PV on the market, driving down prices as companies struggle to sell what they were producing. With that said, these panels are a much better technology and not subject to all of those same pressures on price, but they're still quite competitive. For anyone with limited square footage to work with, they're a great choice. For those building a larger, permanent array, brand new, name-brand residential panels can be had for $.40/watt or less. Apples and oranges, but important to understand as you look at each type of panel.

[@HOBOTECH]

That 40c per watt doesn't include shipping. Pallet of 30 residential panels shipping is almost $800 for me. No one ever factors that in. Agreed, if you're doing a large build to get 450w or bigger panels.

[@gavjlewis]

It seems here in the UK solar panels are one of the things that are actually cheaper than in the USA!😮 Here a 400w (54 cell) residential panel costs from £60 ($75) or about half the price. Also for most cities you can just drive and collect panels locally for free. If you need 30 panels (not many people here have that many as we have small houses and yards) you might need to do three trips in the car.

[@ngk330]

@@HOBOTECH might want to check back into residential panels, 12X 370 watt (480 bifacial potential) comes out to $1,511.91 after shipping and tax. just under 41 Cents a watt. BUT i understand not everyone is looking for that many panels to deal with.

[@roncruise4]

This looks like the perfect power dense panel to mount to the roof rack on Lexus 100 Series LX470. There's not a lot of space up there. I've only allocated the front 1/4 of the roof rack for a solar panel. This may fit. Thanks Hobo!

[@mickeybrumfield764]

Solar panels are getting good. The shade tolerance is an impressive feature of this TopCon panel. Everyone should have these on their roof.

[@Fl4ppers]

The dual panel design is about 20 years old tbh. Other companies are splitting each cell up into its own thing, running them parallel with bigger busbars and different types of junction box on the back to really maximise it. Makes it really heavy but really efficient.

[@mattheword]

@@Fl4pperswhat are some panels with that tech?

[@Fl4ppers]

@@mattheword I honestly dont know the name, I saw a couple mentioned on youtube about a year ago. Might just be one smaller company. Instead of the usual junction box it had one about 6x12 inches on the back. You can also get water cooled panels now too. Linus did a video on that.

[@robinrapport8728]

I’ve been using bi-facial panels for a couple years now. Last December I purchased eight,115 watt bifacial panels from Renogy The power output on these are wonderful. I experimented and put mirrors and reflectics behind the panels, which makes a big difference.

[@junkerzn7312]

About 8-12% smaller than a typical 200W panel. Not bad. The low-light performance is supposed to be quite decent due to the relatively low cell losses (that goes hand-in-hand with the temperature coefficient). Its a bit unclear what their degradation rate is going to be in the real world. Shading losses for single-panel configurations are strictly a function of the number of bypass diodes, which is why "half-cut" panels (which have double the number of bypass diodes) are considered. The cell type doesn't matter unless it has per-cell built-in bypass diodes (which none have these days). Partial shade doesn't stop my 100W Renogy's as long as I orient the panel so the shade only covers one sub-string at a time as it progresses, just reduces the output by 1/3, then 2/3, then 90% once fully shaded. Solar panels have dropped in price radically across the board. $1/watt isn't that special right now with 100W panels going for $65-$75 (amazon price, hard panels, fully delivered). 200W panels are fairly cheap too, definitely less than $1/W. In fact I even see a number of Bifacial 200W panels on Amazon sitting at $160. The lowest price I see is $140-ish for 200W "Alrska" panels. Hmm.. that's actually quite interesting. 43" x 35" which is just about exactly the same area as the TOPCon BougeRV panel. I dunno about the brand (never heard of them), but the cells kinda look like Maxeons with hidden busbars. In anycase, the price decrease seems to be universal. 300W panels running $250. Etc. -Matt

Thank you for the early look Prof Hobo.

[@dbdbgriggs]

I recently saw an article on bifacial panels, and the bottom line was that they perform well vertical, and oriented east-west, perpendicular to the normal panel placement. It sacrifices high noon production, but does dramatically better morning and evening.

[@HOBOTECH]

Morning and evening sun is the worst for output due to the sun going through more atmosphere. Pointing them south at the correct angle for your latitude will provide the most output over a solar day. Anyone saying otherwise is just pondering for clicks by trying to be controversial.

[@unknownquantity4440]

@@HOBOTECH Well, yes, and no. There's a good bit of research of vertically oriented bifacial panels vs. standard south-facing panels angled perpendicular to solar noon sun. The results are closer than you'd think in the summer. However, there's a larger difference in the winter months when the sun is lower in the sky.

With the size so small, I could see getting multiple 100w panels and placing them in series for car camping. My folding solar panels have flexible legs unable to hold the panels during the wind. I just save the cardboard box and hold the panels there when taking in and out of my car.

[@junkerzn7312]

Finding panels that are a best-fit for whatever form-factor you need has gotten a lot easier. I use a ton of 100W panels off a back railing simply because the form-factor is an almost perfect fit for a 3S configuration in between each post (charging a 48V battery system, so it needs roughly 65V VMP to work well). I've considered upping the dimensions numerous times to increase the power density but so far nothing has been able to fit that form factor better than the 100W panels I have sitting there now. I do have much larger panels on the roof, and two large residential panels on top of a Pergola. Fitting the form is the way to go!

[@marsrover001]

This could bump my theoretical roof wattage from 2200 to 2400w. But requires much more bracketing compared to 550w bifacials. I have an extension cord for now. But glad panels are getting better when I do finally switch to full off-grid.

[@TheCornucopiaProject-bd5jk]

These could be perfect on the solar arch of a sailboat. The waters reflection can give it a nice boost. I was thinking of installing solar on the south wall of a cabin in New England. This panel with its two zones installed in a high/low configuration would allow the top part to catch the light very early and late, the bottom when the sun is at its apex and the full panel the rest of the day. I’m thinking winter sun. As a bonus, the bi-facial properties still allow some light to make it thru the window which would be covered by these panels. The wall could host 4kw of solar panels. So we should be getting 5-20kw daily. How much sun would a cigs panel catch if you install it on the backside of a standard panel?

I'm pretty sure that Standard Test Conditions concerning temperature coefficients are measured from the panel surface itself, not ambient air temperatures. My panels, not bifacial but monochrome, regularly run about 130 degrees Fahrenheit in 85F ambient air temps. on clear, sunny days ground mounted over grass. Even so the temp. coefficient you cite in you review is lower (better) than most panels. Love your work.

It is ambient temp but in a lab under artificial light. So you're right, the panel is tested not heat soaked. Mine was soaked in direct sun in all tests.

[@SalmonKing52]

@HOBOTECH “Professor Hobo” almost all RV’ers flat mount their panels only an inch or so above the roof surface. What kind of gains are possible from a bifacial panel under those conditions…even in bright sunlight? These panels would otherwise be perfect for my application to get maximum wattage on the rather small available space on my RV.

[@HOBOTECH]

You'll still get some benefit (~5%) with only an inch gap on a white roof. The bigger the gap the better and the effect is higher in winter when the sun is lower. The main selling point is the 200w has diodes that split the panel in half, so shade tolerance is 50% better than other panels.

There can be a benefit. Let’s imagine that the 100 watt panel is exactly half the size of the 200 watt panel. That means two 100 watt panels give you 4 zones instead of 2. In Hobos example when he covers the middle, affecting both zones, you would still have a working zone from each panel giving you 50% performance.

[@junkerzn7312]

Another thing to consider... really the main thing to consider, is the form factor. You get panels that are best-fit for the form factor you want to mount them on. Be it a golf-cart roof, or a fence, or a railing, or the top of an RV, or house, or ground mount, or whatever. It is always possible to make just about any configuration work, really, so optimize for the form factor and the wiring first and worry about panel wattages later.

It's not quite true to say that the panel has cells on the back, they didn't buy/manufacture an entire second set of cells to cover the other side of the panel. They've just engineered a cell that can absorb light from both sides and a panel and wiring arrangement that allows both sides to be exposed to light. It's the same number of cells, there's just a second chance for light to hit the panel bouncing back from the substrate. I saw an experiment on another channel where he used bifacial panels and set them up vertically like a fence, the idea being that it would give better performance in the beginning and end of the day and in winter because a vertical panel can't have any snow sitting on it.

the 100v is max input voltage ( max input amps is 35) from the solar panels the 30 represents the max output amperage based on the battery voltage the victron spec sheet says with a 12v battery max is 440 watts and with a 24v battery it is 880 watts. 2 or 4 panels at 200 watts each is all the controller will handle.

[@HOBOTECH]

I own 6 Victron controllers. I know how they work. What I said was THE CABLE is rated 30A. Put as many as you like in parallel until the cable melts is all good with me.

[@Mikesroadtrip-ec5kp]

Could I use 3 panels in series with my 100/30 victron mppt? ​@@HOBOTECH

Hey @hobotech I have 6khwr of Delta 2 Max, I broke my portable Ecoflow solar panel. and am looking for something more portable and maximize my wattage, what can I use? I'm placing it on a 6x12 trailer, these solars look great. but since ther'es two inputs' and voltage limitations how do I go about this

[@HOBOTECH]

You could use these or the Yuma CIGS I reviewed a few months ago.

[@timmyleong4183]

⁠​⁠​⁠@@HOBOTECHHow many of these 200W bifacial panels can I connect to the two solar inputs of my Delta 2 max?

[@legaleagleandpaws8198]

How can 12 200W of these panels wired in series (6 per string) and parallel (2 strings) be 149V at 19amps if the open circuit is 36.4V for each panel with six of them being 218.4V ??? Am I missing something. Thinking of getting the new Pecron E3600 - two actually for 240V at 7200W - solar generator. That can in put 2400w max of solar (1200w each plug in) but the input voltage is maxed at 150V for each 1200w plug. So how are 12 panels having only 148v input and just under the 20amp max which is OK. Long time subscriber and congrads on your booming channel. God Bless:)

[@legaleagleandpaws8198]

Would I be better off getting their 300w bi-racial instead to get to the 2400w?

[@HOBOTECH]

You're looking at the 24v version of the panel, not the 12v that I reviewed.

[@legaleagleandpaws8198]

@@HOBOTECH Uhh, so what do you suggest for the PecronE3600 as far as getting the full 2400w charging capacity? Btw used to be "RVlegaleagle&paws" but decided to get a cabin in the White mountain region of New Hampshire so this will be a ground tilting situation. Thanks for the fast reply would really like to get your input from a trusted source. God Bless:)

Really buddy tell me about that other solar panels that get 400 or 450 watts. 200 watts is diddly.

[@Zelza-007]

According to my research, you are supposed to be facing it true north if you are in the southern hemisphere, and the opposite for northern hemisphere.

[@HOBOTECH]

Obviously, my reviews are based in America, so I said to face panels south.

[@Zelza-007]

@@HOBOTECH but if you live south of the equator,which I believe you do, you should face them towards the equator/north, towards the equator. Am I wrong?

Set up the panel and then lay a sheet of aluminum behind the panel to see if it can grab enough sunlight from both sides

[@EcoholicsAnonymous]

Telling people that you can put 4 of these in series for a DP with 150v limit is bad advice. Just a little cold will create black magic smoke. The right config is 3s3p for a DP, not 4s3p.

[@stevenjr8641]

Any body know how I can use solar to power a spider farmer 200w grow light 24hr????,😶🤔plz it would be big help

[@BasedOcra-extended]

2400Wh(12h charge) or 4800Wh(24h charge) battery + 400-800W solar (800W or more for low sun areas). You will potentially need a huge battery/grid/generator if you don't get sun for a few days.

[@brucey5585]

You are better off building a greenhouse and using the spider farmer at night while the natural light in the daytime. You will need close to 10kwh of battery and 3000 watt of solar for that setup.

[@tinkering123]

Thanks Pro Hobo. Still tinkering with my dinky system. All your info helps. Gett'n smarter n big'r.

[@HOBOTECH]

Like the other person said, only run the lights at night to save power. Take 200w X hrs needed, and that's the watt hour of the battery required. You'll need those watt hours divided by 5 (hours) watts of solar to recharge during the day.

[@junkerzn7312]

And deal with winter, and have enough battery buffer and solar to deal with poor weather. It really depends on how reliably you want the solar system to operate. One thing to note here is that if you have access to the grid and you just want to use the solar/battery system to reduce your electricity costs, that's a much smaller system than if you were off-grid and needed to run the greenhouse / grow-light reliably 365 days a year. The smallest cheapest system you can get is basically just a beefy power station. If you are a rank beginner with solar power and batteries, a power station is really the safest and easiest and cheapest way to get started. Just start really small and run with it for a few months to get your feet wet and begin to understand all the issues. I would recommend something really simple and straight-forward: * Mid-range power station in the 500-600Wh storage range. Just to start. It won't be big enough but you don't want to spend a lot of money getting your feet wet. * Enough solar panels to max-out the power station's input. Typically 3 or 4 100W panels and typically in a 2-series configuration and two or three sets of those paralleled. * You still want a combiner box and probably a MC4 crimp kit. Its just safer all-around verses what most beginners do and buy those really horrible MC4 paralleling connectors (that are fire hazards). * And then the AC input to the power station from the grid can just be on a timer that charges the power station up to full from like midnight to 2am or so. * And another timer for the grow light as appropriate (though most grow-light operations run the lamp 24x7). Cheap, simple, easy to understand, and gets your feet wet. -- LEVEL 2 -- The next level up is to start working with discrete components. But there is an easy intermediate step and that is to us an all-in-one MPPT/Inverter/AC-interfacing/the-works box. These can be simple and small, but not necessarily well-rounded or efficient, or they can be large, expensive, and complex. Going really cheap and not worrying about quality so much, we're looking at, oh, a Renogy 48V all-in-one ($600), or a PowMr 24V all-in-one ($520). Or an Eco-Worthy 3000W 24V all-in-one ($490). Minimum system voltage 24V. 24V or 48V. Avoid 12V (it won't scale well). Then you basically wire everything into it, taking into account the voltage range supported by the solar input and so on and so forth. Requires a bit of electricial DIY vibes. Typical tools: * Wire stripper * Ferrule kit w/crimper * MC4 crimp kit w/crimper * 10 AWG and 2 AWG cable. 2 AWG for the battery cabling, 10 AWG for the solar panel cabling. * Insulated tools Klein is fairly good. * Batteries. Can be simple. 24V or 48V depending on the system voltage you chose. LiFePO4. 48V batteries are 51.2V nominal 16S LiFePO4 (don't get 48.0V nominal 15S LiFepO4 batteries). For example, you can buy discrete LiFePO4 battery about the size of a regular car battery 100Ah @ 25.6V or 50Ah @ 51.2V depending on the voltage you selected. You can buy larger rack-mount batteries that are typically 200Ah @ 25.6V or 100Ah @ 51.2V nominal. All LiFePO4. Etc. And you can parallel as many as you want (though the more you parallel, the more you have to deal with safety fusing and breakers). * Solar panels. Start with 3 x 100W panels and scale up from there. * Solar combiner box. Even if you are only starting with one string, buy a combiner box and use it. This gives you expandibility right off the bat for later on. Its worth the money and time to do this from the start. * Main battery fuse. MRBF (Marine Rated Battery Fuse) & appropriate mounting gear. * M8 bolt, washer, and lock-washer kit (M8 is the most common terminal type. Other common types are M6 and M10. But M8 is the most common). * Battery bus bars if needed. Typically 100A+ on Amazon, basically these are simple busses with additional terminals and plastic shields. One for positive (red), one for negative (black). * A backboard to mount everything on. * A DIN rail can be useful for mounting DIN-mounted fuse holders and MCBs (miniature circuit breakers) and other stuff you might want or need. If you do wind up thinking you need MCBs, get only 2-pole unpolarized DC MCBs. A good brand on the cheap would be CHTAIXI. Type B, (faster trip) not Type C.... Type B is safer for beginners and tends to be a bit higher quality. Note that you can always throw in additional charge controllers connected to the battery bus. You aren't dependent on just the one MPPT that all-in-one units have. -- LEVEL 3 -- Level 3 is going full-on discrete components for everything. This is already a long posting so I'm not going to cover it here. For more advanced DIYers who really need to scale-up.

This company has one of the worst websites I've been on with all the pop-ups and having to close them and trying to look at stuff is almost impossible and then gives measurements in millimeters. I think both is a huge turn off for any customer especially American customers.

This video is sponsored and should be marked as such. You missed to state out that it did not outperform any ordinary Solar Solution. A buck per watt isn't a steal... love your content though....

[@HOBOTECH]

Video is absolutely marked as sponsored and plays "paid promotion" at the beginning. It's enabled by default. I don't have to state anything, you make your own conclusions. I was not testing in perfect conditions and don't make claims without testing.

[@Alleinerbe]

@@HOBOTECH I apologize! Well it isn't marked as "Ad" on my Fire Tab with cfw. My point was that, even if you are/were sponsored you would keep it real and are not influenced. In other videos you usually refer to a wattage per buck ratio. And compare it to other brands. You also stated that black panels absorb more heat and therefor perform less good than white and colder panels earlier. You skipped this part in this video despite knowing better and instead say you could get the nice looking black for the same price. Any Module is bifacial, if you do not sunproof the back. No word about this marketing trick. As an engineer i love your channel because of your objective and scientific approach. so i do not have to test things myself. Your honest and profounded opinion is what makes this channel trustworthy and sympathetic. After all you're Professor HoBo. Great Knowledge meeting not so great income. I tried to keep my critics based on facts and i still like to drink a beer with you any time! After all it's just my opinion. Cheers
