Your videos are always spot on! I discovered the ‘truth’ about polycrystalline panels about a year ago. Your videos are spot on and devoid of so much BS seen everywhere else. Bought your book and reference it all the time. It’s hard to believe but your writing is actually better than your videos. Your ‘shameless’ endorsement of your own book (I love it!) is not bragging if it’s the truth! (I left a review six months ago). Keep up the good work.

peter nissen says:

Size: 819/1046= 78%, the Pol panel is 22% bigger.

Output: 70/57watt =81%, the pol panel put out 19% more power.

So, the difference in output, is explained through the size difference!

FANG STALKER NINJA MASTER says:

Am I the only one that can't see any readings on the device in his hand?

Babatunde Aremu says:

This video is really helpful.

Brain Wang says:

Hi Boss
Could I work for you? I have more than one year experience in installation of solar system on roof.

day dazed says:

Omg I love your vids you are awesome at what you do but your voice after a few hours gives me a headache lol god I hope your balls drop some day

Derek Rusinek says:

interesting renogy only seems to be offering polycrystalline panels now

Aleric Johansen says:

Maybe it comes from the fact that more materials (variety) are used? Thus over time the poly panels break down, while mono panels maintain their power output.

Ray Wilcox says:

Thank you so much for your video's. I was able to hook up my (inherited) 2 x 200w poly solar panels and all the fixing with your videos and book onto my Class A. It was easy to set up and make sure I had all the right items and equipment. Great Job and keep it up!!

Emmanuel Manahan says:

I vote Polycrystalline

William Cowell says:

I feel like a party pooper, but I have to say you seem to have overlooked one simple fact: in finding that the polycrystalline panels produce more power, you ignore the fact that the poly panels are 33% larger. As the available energy is a function of panel area and conversion efficiency, for the same efficiency the larger panel will always win. I like that the poly panels are cheaper, that's a win for me, but your apparent conclusion that the poly panels are inherently better doesn't stand up to examination. A fair test would be to have identical sized panels and compare them.

Strange thing Rich Solar panel not available in India 🙁

Paul Ladendorf says:

Thx for the vid. Just bought 4 Rich solar panels from Amz. They didn't put out even close to spec (<4.8 amps/20 v) so I returned them.

MrSteel says:

No one can seem to say how much more efficient a MSW inverter is then pure wave at running different electronics. Some seem to argue that it’s more efficient too create a MSW but electronics work better with a pure wave. There is a hypothetical figure of 10-20% repeated all over the Internet, but I can’t find where people came up with this figure.

Steve Amzoun says:

Not to forget the size of each 🙂

Sir Budz Page says:

I bought mono, have a low short circuit current, Unlike my old poly. Polycrystalline wins. Google says mono win🤦‍♂️

R C says:

Hi Will, I just found a youtube video showing Victron doing a similar experiment using 4 different types of panels. It's a live on going test. If you goto the Victron website click the top left part of the page for real time updates. But they are not showing the same results as you as for Mono vs Poly. Curious what think might be the difference. Their setup looks pretty much as identical as possible for the test.

Good evening, DIY Solar Power with Will Prowse. it's a exceptionally okay video. thanks. 🙂

Darlene Royce says:

Shopping for solar, your videos are EXCELLENT. Perfect info to help me decide. Thank you for all the help.

Petr Hejtmánek says:

shading can be reduced by tech

p b321a says:

How about an update to this video for 2020?

Jottka says:

6:37 That's Curry.

Sonny C says:

i googled online and it says a oven uses about 2400 watts an hr to run so im guessing all these people with offgrid cabins are not using ovens indoors and such? or they have a heck of alot of solar panels and a huge inverter of at least 3 thousand watts….so in short im guessing that these solar panel systems are mainly for the usse of smaller electronics and such and things not as big as a oven or stove …and maybe only a bar fridge ?

Algomarble racer says:

Yo. Don't forget the lifespan of each panel. Monos last 10% more longer than Poly. If you wanna buy a Monopoly crystalline panel, though… Buy houses and properties.

ᴍᴇɴᴏɴᴛᴏɴ ᴠɪᴅɪᴏ says:

wah tak kiro koyo koco cah jebule kok malah koyo karet ban ngono haha

Toshi Hoo says:

Will, really love your videos and this one was super helpful. I'm very curious about Renogy's Eclipse panels. They make similar claims of increased power efficiency as monocrystalline panels do. Have you evaluated them?

Elliott Schiller says:

Anyone notice any difference in durability or weight for mobile applications?

Rondo Cat says:

Why do no one test in totally overcast rainy days with absolutely no sun at all… Myth has it that amorphous and polycrystaline give more watt pr m2 then monocrostaline in low light conditions with absolutely no sun. But I can not find any real world test of performance of panels with thick cloud cover (the usual weather here that can last for weeks with absolutely no sun at all).

I live in North Norway north of polar circle and now my one 100w monocrystaline panel on my van give less then 0,5w on a cludy day (this late in the year sun us low in sky), if the myths about amourhous thin film panels is true then it would be better for me to use those kind of panels then mono… Only found one video of a guy that had 4 panels with 100w of amourpous showing he ha 0,9A of charge (no mention of watt or volt) on a cloudy day 30 min before sun came up. Also lot of claims from people that have amourphous panels that they give lot more power then mono and poly crystaline panels when it is thick clouds.

I want the panels that is most effective pr m2 when it is real THICK cloud cover (like a dark rainy day) as I have limited room on the roof of my van. But it is impossible to find any data for performance when there is no sun for any panels…

Kannan Nithiyanandam says:

How do they compare when there is good sunshine?
