Increase in insurance premiums 40% year over year should be added

Perfect explained!

8:20 are you getting some of the other side lit up in your single side tests through the lit up side? (i.e a fully lit up back side would not get the full 149%)

How much battey do you have for 25kw I had 57.6kw of lead acid batteries was going well until Igot 2 bad 6V batteries putting out each 4v I am off grid and upgraded t0 a BYD LVS 4 with 12 Kw I have 3.4kw of panels is it big enough for 3 days overcast ? \

From 6% of battery life, how long did it take for the batteries to be fully charged to 100% And how much power was used to charge them? Thank you!

New sub to help you out. Great info

a ladder lift is the better way you can even make your own, great job guys

I'd be very interested in temperature readings on each of these through the seasons too

What rate of electricity are you using? It’s gone up slot in 3 years

Now, integrate mirrors into this idea! You could get rid of much of that mid day dip if the mirrors moved to follow the sun- at least that's what I think would happen. Wouldn't double sided panels cost about twice as much though? Since it has twice as many solar cells I figure you should be comparing 2 regular panels to 1 of these vertical panels. I can see how these are beneficial if you don't have the space but I kinda feel like the graphs are a bit deceiving- compare the amount of cells and their output for a real 1:1 performance test

This is the only comprehensive, downloadable spreadsheet I have found that works! Thank you for sharing it.

good video 👍🏻

So has there been any testing for motorised panels that track the sun to maintain maximum output throughout the day? In the game space engineers it is a common method people build. It would basically be panels set up like your south facing but on a mount that rotate the array from east to west as the day goes by.

What about a 15° tilt bifacial instead of true vertical? Steeper incline, less snow stickage, but a bit more of the noon sun like the normal 30° panels, and a thinner horizontal profile than 30°, allowing more space at a slight sacrifice over true vertical?

Hi Dave, i have 20kwt solar system for sell electricity, and now building 6*580W jinko panels for my home with hydrid Usful 5.5 kwt inverter- thanks for your video. I want to share with you Ukranian dude’s video where he explain phisical process, why it is necessary to use East and West sites. Use google translate-it is on russian, so you do your own detail video about this effect

As someone mention Mylar for a reflective surface would be interesting, but with the added maintenance of keeping it clean it adds a lot of work and a greater leap in cost than something like white landscaping rock. I would be interested in the performance of something more feasible like white gravel. If you have time to test it I’d love to see the results.

You should trim that small tree in front of the panels though to make a better comparison.

This panel design would be incredible in the northern latitudes in winter where the sun is always fairly close to the horizon. You’d definitely want to flip these up in a more traditional orientation during the summer though since the sun tends to track very high.

Thanks very informative 👍

South facing vertical pannels would he interesting.... We have a south facing fence with pannels almost vertical (15 degrees) and they wirk great... Especially in the winter... Autperfoming the 3x sizesd east west installation on our rooftop

12v batteries can be bought in 5kwh. & their price is on par with 48v 5kwh..

If you’re running mostly 12v appliances then why choose 48v and loss efficiency on your buck converter? The real killer for 12v is the solar chargers on the market for 12v (say victrons’ smart solar chargers) are around $600 per 1kw of solar input, whereas 48v is 4kw per $600.. If you’re never going to expand your solar array then it would be fine.

Yall really tore the heck out of that roof. Walking over it way too much and all the metal yall scratched up. Dang.....

That positive cable to power the shunt is sadly missing a inline fuse, which is bad news. Hopefully you correct that. Had to mention it, now back to finish the video.

Very nicely presented and interesting results. One question that intrigues me is whether installation of bifacial panels on a pitched roof (say 30 or 40 degrees) with a north-south ridge could work well. Such a roof is really inefficient for single faced panels with normal mounting, but maybe wind loads get too stupid for vertical panels.

oooof, guess you have to be a kid to go on gravel roads and grass without suspension. Nearly threw out my back just watching him drive that thing!

This is Straight legit 👌

I'm interested to see a comparison between bifacial, south-facing vertical and 30d installations.

I dont see the point of these things unless they had charging backup like solar. If it can only run a few things in a house for a hour what is the use of it. I have a 3kW sine wave petrol generator for £250, runs until it wears out.

I have 2 years experience solar Pv System Installation Technician in Saudi Arabia job available sir

Awesome video! Very helpful. Thanks!

1:07 could be solved just by mounting the panel on a swivel and have a RPI control the movement. Put a mirror under it.

Actually lead-acid batteries are from the 19th century. I will grant you the packaging of that battery is 20th century.

The whole point of installing vertical panels is to reduce heat and therefore maintain performance. Panels installed in snowy, cold areas are therefore not going to be as hot. You've clearly missed the point.

Merci pour cette vidéo je suis en train de monter un multiplus 5kva, quelle section et quelle marque de câble utilisez vous pour la puissance du mppt450/100 ?

Have you only got one charge controller going ?

I appreciate your video, it gave me some of the information I want. The hybrid structure is likely what most people want. What most people don't want is a high pressure salesman pumping up a profit margin and a commission.

Im 356. 9,644 to go!

A word to Judah, you are a very fortunate young man. Learn everything you can from Dave! What a great opportunity you have - don't pass it up.

Sarcasm alert. Come on, Dave! Those faceplate screws should be vertical. Unsubscribed!

Superb work as always, Dave. I've had a Chevy Volt (2 different model years) since 2014. My current is a 2017. It is a plug-in-hybrid, so a bit different on all these calculations. I like the whole idea of a plug-in-hybrid simply because I can use gas any time I actually need to. However, with my typical commute, I fill up my gas tank roughly once every 9-10 months (just over 8 gallons at Seattle's ridiculous $4.95/gal). According to my Volt, about 92-93% of my miles have been electric alone. I have about 82,000 miles on my current Volt. I've had to replace my tires due to wear only once so far. Two oil changes so far. That's it. Things I like very much about my Volt are how smooth the power/acceleration is and how quiet it is. I absolutely love it and will probably drive it into the ground (I'm hoping for, oh, 150k miles). Keep up the great work.

Hello Dave we recently came across a company that is working on on-grid / off-grid solar power booster where their system generates power even before sunrise and after sunset. Its is combined with solar and generates a steady peak power output irrespective of weather conditions.

You guys should throw one of those suspension seats that they use on lawn mowers in that thing. Save the kid a ton of future chiropractic bills. 😂 I might have to put one of these together for my nephew. Build him a little shed to be a solar charging garage for it.

+1 like from me

Nice, looks like fun! It was neat to have a little tour of all your solar setups, and smart to link the related vids too.

Doesn't faster charge destroy the battery's cells?

Results are convincing, cost isn't. Bifacials cost over double around here.

Sweet. The outro was fantastic!

Great video! I appreciated how you took the time to explain everything in very simple terms for Judah. That was so helpful to me - someone who is new on the solar journey. And, now I want to buy one of those go carts for my kids. :)
