This is very similar to what i hope to do on our trailer! Since it spends most of the time parked next to the house it can provide nice for the car! I would like to add the ability to hinge for better solar gain, and a large battery bank for extra range while camping if we get our Rivian next year.

There is significant variability when it comes to a solar production. Even perfectly sunny days in a row will have slightly different amounts of solar production. In over 7 years of monitoring solar I have only seen two days that were literally identical to the hundredth of a kW from one day to the next. The purpose behind this video was all about how I attached the solar panels on the roof of the RV. I have a ton of other videos that cover the production in varied circumstances from the winter to the summer. Here is a playlist of a trip that we went on and I cover the solar production throughout the trip and there are many other videos on my channel when we take the RV out and I always cover the solar production in our camping videos. In brief summary on the shortest day of the year on a perfectly sunny day the trailer can produce about 5 kWh and on the longest day of the year on a perfectly sunny day it can produce 20 kWh. Then of course the panels can produce as little as zero when they are covered with snow or on a completely cloudy day it could be just a little bit more than zero. Then because this is a mobile device there are times that we park in forested areas and then there is all kinds of variability there with how the shade from trees moves across the panels throughout the day. I have several more camping trips that I'm still working on editing that will be published eventually covering varied circumstances.

Excellent video. Thank you so much for posting it! One question about the air flow in relation to a flat rooftop array design. Now that you’ve put some miles on it, do you think there would be any benefit to installing a front “spoiler” to deflect the air up and over the array while you travel to improve gas mileage? Or do you think the best MPG is achieved when the airflow is both under and over the array?

@ElectricTechAdventures

2 жыл бұрын

I'm not an aerodynamics engineer but if I had to guess, there is probably some benefit having a spoiler to push the air up over the smooth flat top surface of the panels. Between the roof and panels there's lots of surfaces to cause drag, but to be clear the amount of drag they cause is far less than the large object of the RV itself hurtling down the road. I doubt the gain would be more than something like 5% but that's just all me guessing based on what I've seen about aerodynamic drag in my life. If I had the time, resources and skills I'd make a spoiler for it and do a before and after test to find out for sure, but I have no intention to do so at this point in time.

@maudessen573

@@ElectricTechAdventures Based on the fact that semis use spoilers to direct air flow up and over their trailer, I can see that there might be a small MPG benefit to having a spoiler in this application. In this case, it would also have the benefit of reducing lift on the array, which could have value as the 3M tape ages.

I can report as well that I have had the trailer in varied situations with significant winds in the order of 35 mph gusts from the back and sides and have had zero movement of the panels.

Excellent job - overengineered a might. I am planning on racking 8, 455 watt panels 13" off the roof of my MH to power a 48v DC Hotspot mini-split (with a 302ah 48v battery bank). Have you noticed any handling issues with an extra 550lbs or so mounted high on your roof? I would imagine that you must be close to your ccc on a trailer that small.

@ElectricTechAdventures

Жыл бұрын

Thanks. I'm not sure which part you're referring to as overengineered (unless all of it perhaps) but if I had to guess I think you're referring to the quantity of rated Watts. It is very much overkill in the summer just for the trailer, but it's actually inadequate in the winter. If I figured out how to tilt the panels then that would help during the winter, but not fix the problem. Heating takes a lot of energy and the days are too short in the winter to fully power heating the trailer even with a 33.1 SEER heat pump mini split. My goal when designing this system was to fit as many panels up there as physically possible because I intend to tow this trailer with a Tesla Cybertruck some day and I want to be able to have excess electricity to charge the truck with. I understand electricity enough to understand that compared to the Cybertruck's energy demands this array is very small, but even just a little bit of extra electricity from the trailer while camping is fun to be able to get. I actually charge my Model S from my RV electrical system on a daily basis and so far the trailer has produced 3,028 kWh in the last 11 months and the vast majority of that has gone towards my Tesla. I intend to make a KZread video about this in the near future. I'm giving it a year of doing it before making a video of my findings. My panels are 9" off the roof and they could have been as little as maybe 7 inches off the roof, but I wanted to have enough room for the vents to move some air still. Removing the rooftop AC is of course what enabled that height. Regarding the weight on the roof I have noticed no effects from the panels being up there and actually there's only roughly 200 lb extra weight up there. I asked Lance what my rooftop storage rails are rated to hold and they responded up to 500 lb. My panels are 63 lb each and there's 5 of them so 315 lb of panels. The unistrut weighs 75 lb. That means I added 390 lb up there and it's equally spread across the entire length of the roof. Then there's the subtraction of the weight of the AC unit that was up there at around 100 lb and the rooftop luggage rails were surprisingly heavy at around 75 lb that I removed. The majority of the added weight is coming from the batteries and inverters under the couch which is much lower weight. As part of this project I replaced the axles on the trailer and had them welded to heavy duty 6 foot long angle iron that is then welded to the trailer frame. In the entire project I removed some things and replaced others and the net difference ended up being 700 lb additional weight added to the trailer. When we go on trips I only put very light things in the passthrough storage, and I put the heaviest things in the bed of the truck which has thousands of pounds of additional payload capacity. I use a Weigh Safe hitch to keep on eye on my tongue weight. If you're interested I have additional videos on my channel outlining the components under the couch, the net weight difference after modifications as well as the Weight Safe hitch unboxing and tour of the factory.

@@ElectricTechAdventures Good deal. It's a well thought out project. By overengineered I meant that your racking appears stronger than needed with the cables in front and using the ladder for support in the rear. Overengineering is not a bad thing, as living Ft on the road for the last 4 years has taught me. Sometimes the weather changes still surprise me. It's good to hear that you don't have any handling issues. I think your beefed-up running gear is very smart and will surely save you problems down the road. I expect the weight and size array I'm planning will require a little more caution on my part, as I will be adding about 475 lbs. on the roof of my 36ft Class A. I might remove my rear AC unit as I never use it, now that I put a new Furrion AC on the front. That thing blows super cold air and is easy to start, as it uses an efficient scroll type compressor, not the old, hard starting piston compressors most rooftop ACs use. I plan on adding a mini split to the rear bedroom, blowing forward down the hall into the living/kitchen area of my MH. I might even use the ductwork currently used by my rear AC to redistribute cool air to the front where it's needed. I once used the 620w array mounted to the side of my MH to charge a pair of electric bikes, but I recently sold them to free up that weight in preparation for my bigger, rooftop system and rear mounted mini split. I will retain my side mounted array to charge my 12v 560ah LiFePo-4 bank. A side mounted array has several advantages. I lift it to the exact angle needed based on latitude and season to optimize production. This is especially important in winter when that 620-watt array pointed directly at the sun performs more like a 900-1,000 watt flat mounted one would when the sun is low in on the horizon sky. The other big advantage is that I can clean it easily without climbing on the roof, which means I clean it more often. Keeping it spotless improves production too. At 66 yrs. or age I don't like climbing on the roof unless I absolutely have to. Good luck using a cyber truck as a tow vehicle. As a general rule, the range of electric trucks is extremely limited when towing - at least for the ones currently on the market. It's smart to tie in your trailer's array to help extend your range a tad. It also prevents you from getting stuck somewhere deep in the boonies where there's no solar charger available, and you've got a day or two of sunshine to bring your batteries back up. It surely makes more sense than running a generator to get you unstuck - as I've seen people do.

@@SuperSushidog regarding electric trucks I agree, but we currently have extremely limited data to go off of. Currently available truck manufacturers (Ford Lighting and Rivian R1T) have very little experience with electric vehicles and the Munroe teardowns have shown those manufacturers struggle with efficiency and other factors that effect range. I'm hopeful with Tesla's experience the Cybertruck will prove better, but obviously Tesla can't change the drag and this inefficiency my travel trailer will add. I'm planning to get their longest range truck at around 500 miles of range not towing. I anticipate getting half that range while towing which will get me the same range I have with my Model S I have now which works for us. Then if we're not in a hurry and we are camping during the summer when there is plentiful solar then we will be able to slowly charge the cybertruck a little bit everyday and gain that much more range. And worst case scenario just not be losing any range on the truck while in the boondocks.

Would be cool to have a solar panel that can tilt and slide to become an awning. Not only would that improve power output, but it would also give you an awning.

@ElectricTechAdventures

9 ай бұрын

Yes I agree, and I've seen in forums others do that and they post pictures and videos of their various solutions. The biggest limitation for me is weight considerations. I kept things as simple as possible for cost and weight savings. I've seen projects where they make sliding trays of solar panels down the length of large greyhound bus conversions or class A RVs and I'm jealous of their cargo carrying capacity on those rigs! To be honest my solar array is plenty for the trailer's needs though. Also I do have a traditional awning already so that's not really a need, but having one made out of solar panels would be way cooler. If money was not a limitation I'd look into purchasing a heavy duty goosneck trailer then remove my trailer's axles and mount it on the flatbed. I'd get a flatbed trailer that's longer so there's room on the back for toys. I saw someone else do that very thing and I think the trailer's weight capacity was something like 20k lbs.

@@GeorgeOu It's probably possible. I didn't look into it much. Perhaps I'll add tilting someday, but so far that hasn't been a priority as I have more than enough energy when camping except for the dead of the winter which isn't when we're camping. I would be concerned about wind though if they were tilted up high enough to match the angle of the sun in the winter. The panels are about 7.5 feet long, so when they're tilted up there would be a nearly 7.5 feet by 18 feet cross section to catch wind.

I got my panels from the same company (Santan Solar) and shortly after I purchased my panels they were unlisted from their website. Now, yearly 2 years later I found the pallet of 540 Watt panels listed on their site so I put that link in my spreadsheet instead to just point people as close a product to what I used as possible from the same company instead of a broken link. I recognize it's not realistic to buy all 30 for an RV project, so hopefully you can find the panels you need from a different company which is why I added in that cell right before the link "No longer listed but this is the closest they now have". Pointing people to an exact product to buy is likely going to be a moving target for the foreseeable future unfortunately. I also asked Matt at Continuous Resources if they could be a source for these large high Wattage commercial type solar panels and they weren't able to get them at the time I asked back in 2021.
