2023 Best Solar Panel Comparison. REC vs Panasonic vs QCELLS vs SunPower vs Tesla vs Silfab

Julian, how can I reach out to you? I’ve got a quote from 2 companies, one is Tesla and ADT is coming out.

Do you know much of axitec 400w panels fair to ?

Juliana run there a huge spider 🕷 on the wall by picture frame. Not by wine rack, the otherside. I have to start video over bcz it took my attention

Hi Julian. Great information. I live in Henderson, Nevada. Which panel(s) would you suggest for the extreme heat and dry conditions?

Hey Julian ... Great videos ... Qcells look to be what Im after, performance and durability what your thought on the Q.PEAK 485 DUO XL-G10.3/BFG the cost hovers about $480 thru a few venders
I new to this and want to set up about 15kv system with the eg4 18 kpv your thoughts ?

"Efficiency, efficiency, efficiency..." Efficiency is relative to the Eye of the Beholder.
For me, the single biggest factors that I consider "Efficient" are:
Cost per Watt, and
Lifespan.

Hey Julian, Im new to solar setups and wanting to DYI an 18k system here in South Mississippi, I'm looking to build an easy no bull system and leaning towards the EG4 18KPV from solarsignature whats your opinion

Hey Julian, enjoying your video;s what your thoughts on half cell panels newbie here and I am planning on building a solar setup here in South Mississippi just in the learning phase now

The one you can afford and can/are using

none of them they all pollute, they pollute in their making and in their recycling.

Hey Julian - (The Solar King). Just taking time to personally thank a fellow Independent Powur Energy, Consultant for another awesome presentation. I have your contact info saved. *If you ever sell in Dallas, Texas area, I'm your ODSS. Have a good one. Tom Griffith - The Solar Man

What about United Renewable Energy Panels?

Hi , very nice video. I cant understand the efficiency and the Power. a 300 panel with 20% efficiency produce less energy than an 20% panel with 22% efficiency? What PV panels you suggest for the maximum energy outpout (no matter the cost).

Everything you could possibly want to know except prices...

Thank you for that great podcast. I have a travel trailer that just is parked. Does it go anywhere and I need the best solar panel to feed my Eco flow, pro solar generator which of these panels would you suggest to give me the most bang for the buck of this list that would be able to handle, the temperatures in the Midwest Missouri gets very cold and gets very hot. Thank you for your time.

You live in Australia or what? Those bugs are supersized. 😮

Julian: Is there a solar option that won't require me to have my system "report telemetry" back to the company? I like Tesla but I don't like that you have to have their telemetry enabled for them to work. I don't really feel like I own a system if it only works hooked up to a telemetry monitoring service.

Hi Julian…

Thank you for all the great information. What do you think about the GAF Solar roof system?

What do you think of the canadian solar 540w?

Thanks! This really helps

A difference of around 2% eff. can only be measured in a Lab with calibrated instruments, it has no practical value in a practical environment.

Not sure if you still see the comments but if you do please tell what you know about sharp solar panels. I bought 8 that are 235 watts each. They have some kinda frosted look to the glass that's supposed to be some kinda light diffuser stuff. I'm not sure if they are decent or not but so far they seem to work great. I'm going to buy another 10 or 12 newer panels hopefully atleast 4 or 500 watt panels for my second off grid system I'm building. Yes any information on the sharp 235s would be appreciated

STC (Standard Test Conditions) panel watt output ratings are based on ideal lab conditions. STC panel rating is calculated at 25°C cell temperature (and not 44°C as you said in your video).
For each additional °C degree above 25°C, the temp coeff will indicate the wattage loss percentage. In real world conditions, here in the Texas, for example, with cell temp easily reaching 50°C in the Summer, a 400W rated panel with .26% temp coeff will lose 6.5% output capacity [ 50°C - 25°C = 25° difference. 25 degree diff x .26% temp coeff = 6.5% wattage output loss ].
To this panel loss percentage, add another 4 to 5% microinverter current conversion loss, 2% cable loss, panel tilt & azimuth loss, etc... In other words, you must figure out a 12-14% generation loss from the panel STC rated output whenever you are designing your system total production. This often translate in the purchase of more panels/microinverters.

I seen that image CRAWLING I WAS LIKE DANG!!!👀😮👀😮 I will watch the video now after reading that it has great information and I’ll be looking for that thing at the end of the video 👀😮😂👀😮😂

Great info! Im learnin..

Ty

First I want you to know that I liked your explanation of all of the differences between solar panels. Great job. I have a question: I have an infrared temperature sensor. A number of years ago I took measurements of the cement, roof tiles, Solar panels. Here is what I found. The outside temperature was around 100 F (I live in Southern California), the cement was app 130 F, The roof tiles in the sun was app 170 F, the Panels were also app 170 F, the roof tile under the panels were app 112 F. Here is my question, I can't control the Sun/ outside temperature but I might be able to do something about cooling the panels. 1) I can put a water jacket underneath the panels( Kinda of a pain) or 2) I can run active fanswhich would blow are under the panels (Since I'm generating lots of power, don't really care about the energy the fans use). Has anyone done a study of the Temperature effect (Panel efficient) by doing something like I described above?

Country of origin is missing... Otherwise this is fantastic!

Thank you for your video! Very informative. Where do the Meyer Burger Blacks fit into this mix? Do you still think the Panasonics are better?

Thank you excellent video.

What would be the ideal 16 panel off-grid setup? No grid-tie.

Good video. Saving your number

Thanks for the reviews. I'm inclined toward the Panasonics, but I've got a severe size constraint. I have space for one panel only, on top of my suv, and it can be 58" tops, by maybe 32" (31.5"). Anything like that in the catalog? Eff: 22 or so? Wattage negotiable...

Oh yeah: Alaska, Ketchikan, cloudy weather half the year... will have a 100 ah LifePo4...

What about the REC 410??

I don't see the point in paying double $ for a slightly more efficient panel.

I love your videos, they've helped me so much to understand the solar industry

Anyone use URE panels? I haven’t seen much about them, but they are what one of the largest installers in my area uses.

Hey Julian. Loved the info here. Now .. which panel is the best considering wattage and cost per square foot. I have a hip roof house and so I'm limited on how many I can install.
Thanks

I just started in Solar and your videos are helpful to understand things. They don’t cover enough in training. I hope you make more videos explaining things!

Hey Julian - do you work for Massachusetts /Boston Area, looking for 17 Panel ~400W Solar system, options available are Sun Power M Series425W or REC AA Black 405W or Panasonic EVPV HK Black 400w. Panasonic would give All Guard Bumper to Bumper Warranty for 25 yrs not sure how reliable they are compared to Sun Power who also give same warranty for full system. REC Warranty only Panel, any recommendations?

I got a 405 watt solar panel that is 44 inches wide and I actually got four of them.

Looks like a tarantula ?

Thanks for this info I live in Tampa FL. What would you recommend for my climate out of these panels ? I have quotes coming next two weeks

Easy choice, REC. They are the most reliable, we also do service for Sunpower and its a nightmare.

Absolutely awesome information, thank you👍🏻 we are trying to find a good sewer company. You’re in Florida.
I do not want to. I’m going for a standalone some companies don’t want to bother with that. ??

Thank you for this information. We were about to go with a PPA, yikes! Would you possibly know a reliable company in Las Vegas, NV. I appreciate any help you are able to give to help direct me in the right direction. Thank you, Gale
