DIY Solar Tracking System Inspired by NASA (Parker Solar Probe)
Рет қаралды 2,238,358
5 жыл бұрынIn this video I demonstrate a simple autonomous solar tracking system that can be used with solar panels or parabolic mirrors to improve their performance in producing renewable energy. For this system I use two 10rpm, 6v geared electric motors, and four 5v, 0.6w solar panels connected in a configuration that allows the motors to constantly move the panels into shade (purchasing links for these items below). The cost of the electronics was about $10, and could easily be scaled up or down as necessary for a variety of solar applications.

We also built a system that was time-based with a wind-up alarm clock. It worked surprisingly well for having zero feedback.

Update: for the problem of the sunrise vs the sunset position: place vertical shades on the east sides of the solar panels to block any morning sun on the west and top/bottom solar panels, with a mirror inboard on the east panel that can reflect the morning sun onto that panel, which would kick start it moving back to the east, until the acute rays became more direct.

Great video! I had seen a one axis version of this in other videos, but they all had the problem of the solar cells being in the light all the time, and therefore always fighting each other to drive the motor in opposite directions. This ended up causing very jerky motion, because there was not enough current to drive the motor until the sun had moved substantially, and then the stall torque finally let loose and let it move, resulting in a jerk motion. Yours is smooth as butter because all the cells are shielded from the sun until the sun has moved, and then only one in that axis gets the light. Absolutely one should baffle it the way you showed, because that will further block light from undesirable direction. Bravo, on a wonderful design!

For a solar system, I think its accurate enough. I dont think there is enough to fuss about such a small angle difference to a perfect angle than a simple experiment like this gives. Also added bonus, if you attach those vertical shields then you maximize the power output even between trees and other shadowy areas or mirror like lakes and such.
@bpark10001 4 жыл бұрын
It doesn't need to be precise at all. As the drop off in solar efficiency is cosine function (which "stays near one" over broad angle) and sensor signal is sine function (which changes rapidly with angle), even the crudest system with 10 degree tracking error will result in little degradation (98.4%). One motor/sensor can be eliminated by setting its axis parallel to earth polar axis (like equatorial telescope mount).

Yeappers, a very nice increase. My system cost me about $40.000. A 33% increase would definitely be worth the small cost of your basic sensor. Bravo to you. !👍

I saw a guy at the Bay Area Maker Faire this year that had an electric assist bike that he made a solar panel trailer for. The panel could only tilt left to right, but the tracking method he used was really clever. It was two photoresistors mounted on the side of the panel, each pointing about, say 20-30 degrees off perpendicular in the axis of movement. These ran to a mini arduino which controlled a tiny linear actuator. It didn't use the shade. Instead, it took the analog input from the to photoresistors and tried to move the panel so that they would equal out. Similar in concept to how yours works, but I'm extremely impressed with the simplicity of your design. I spent the first half of the video looking for where the arduino!

MrRasZe true, but they aren't very good diodes and can easily break down in reverse polarity (multicrystaline cells can break down at reverse voltages as low as ~12-13V). That's why many panels come with builtin bypass diodes to prevent damage (because even in a normal setup, where you have multiple cells in series, single panels or cells might be in the shade while others continue to push current through them). If you happen to have solar panels with builtin bypass diodes, the proposed design will not even work (as the bypass diode of the shaded panel will short-circuit the motor). Adding a simple blocking diode for each panel doesn't hurt...

Superb concept. One possible adaptation that would overcome the problem of opposite horizon sunrise would be to slightly angle each of the smaller panels outward. They could still be completely in the shadow of the large panel when it the sun is up, but when it rises or comes out from behind a cloud, having them at an angle will allow them to still catch a little sun. The angle would make them slightly less effective, but those motors wouldn't need to turn quickly anyway.

@shannondwhite Жыл бұрын
I would not recommend a diode. In this setup, the energy is only for and going to the motors, and if they do their job, leave it. The voltage drop on typical diodes is around half a volt. At the size of the panels and motors used here, that half volt may cause it to not work or be slow to respond (behind the sun). If the panel is 5 volts at peak sun, and its a little cloudy, that drop may prevent detection. The energy wasted in the other motor does not hurt anything (won't overheat), and the system works. Even in a larger setup, a diode could be added, but wouldn't be needed (an extra expense and effort). --- Typically you would use a diode with a solar panel, some have them installed already, but in this case I do not believe it is needed.

...until you have an overcast day and the tracker is wandering all over the place constantly, trying to find the sun through varying cloud densities (which could cause it to use more energy than what the array above it can harness during these conditions), or a wind storm happens on a sunny winter day when the panels are at an extreme angle - then it becomes a sail. Not a big deal for a tiny model like this, but if you've got a couple thousand watts of panels to worry about, you'll wish you spent the $200 on a proper controller that can program an automatic homing position to maximize harvest during overcast conditions, and senses the wind speed with an anemometer and automatically angles the array out of potentially damaging winds, which are becoming increasingly extreme as time passes...at least here in Atlantic Canada anyway. A very small price to pay to protect a serious investment.

...and just an FYI, this isn't a new concept. A friend of mine built something very similar a few years ago. It's here on KZfaq. My commercial controller uses a similar sensing system too. Very simple. But it does employ a controller for the sole purpose of providing the aforementioned efficiency and safety features.

You could try angling the panels away from each other. That would reduce the potential for the sun to hit all of them while increasing the potential for them to catch the sun when it is facing the absolute wrong direction (such as at dawn or after a storm).

So it is simpler and more elegant than the one I designed using a raspberry pi. And the sun shade at the end was the answer I was looking for with regard to the sunset/sunrise transition. Well done! I still prefer my aoftware automation as the cost if very low, and I can aim through the clouds. This was not my first tracker, back in 1978 I wrote software for star tracking for telescope use, and that implementation was very much a clock-like function based on sidereal time. It was a go-to system with a database of celestial objects, so it was very similar to a modern goto telescope. One sensor I made for the sun tracker was solar cells arranged on the inside wall and bottom of a short shadow tube. It was effective and compact, but it's role was as a alarm for a failure of the raspberri pi... In practice the aim alarm never fired, but it was tested to work. In the end I decided that aiming a large array wasn't practical, instead I opted for manual seasonal configuration of the panel elevation with a fixed azimuth. After all the aiming work, I decided not to do the aiming... But it was fun to revisit my old ideas from the 1970's.

Great idea. It triggered the following thoughts ... Scaling it up will take some thought. The weight of a substantial solar panel will require a much heaver structure. To use such small motors means that the moving structure will have to be well balanced. This balance will require consideration of wind load as well or the torque of the small motors will not be sufficient to contract the wind (not a problem in space :). Gearing the motors down more would give them more torque. The question is, how slow is okay for the tracker to acquire the sun? I think the sun moves about a quarter of a degree per minute. [360 degrees per 24 hour day / (24 hours * 60 minutes/hour) = 0.25] So maybe the tracker could move one degree per minute. Another possible simplification would be to eliminate the elevation axis. Just have a polar aligned mount that presents the panel at the average elevation based on the latitude of the installation. I think the loss of power generation would be negotiable at most populated latitudes.

Instead of solar panels driving motors directly, I've seen it done with light dependent resistors as inputs to a microcontroller that in turn controls motors through appropriately sized motor drivers. Saw one with a roughly 4" diameter setup with about 6" tall shade cross (as he suggested to use the cardboard), all mounted on the front of the structure next to the solar panel

there are a few ways you could scale this up, one is to put this on a 2 axis solar panel, and have this power relays to move larger motors. Or another option is to put this tracker off the solar panel assembly and to make it so 1 degree of motion of this tracker is 1 degree of motion of any solar panel motors to move large solar panels, and so you basically have the other solar panels just mimicking the tracker.

Mounting the panels at a 20-45 degree angle to the front board would help find the new day’s sun first thing in the morning, the solar cell would seater its own shadow on one side, the opposite side would be better angled for the new sun.

people say spending money on any form of blue skies research is a waste, but they don't know what they are talking about. such research acts as a driving problem, and even if the eventual outcome is impractical, the commercialisation of the resultant technology to get to that point usually returns 7 times more than was put in to get there, so even if you had not got satelites and launchers, the return from things like teflon and the improvements in computer reliability would have been worth it by themselves. this is backed up by hard data from tracking the return on the money spent for the apollo program and many other examles.

That is awesome! Another improvement might be to angle the solar cells outwards (45 degrees maybe?), so incoming sun from the side does hit one panel more perpendicular (and the other possibly not at all). Edit: possibly the eastward-facing solar cell should be 90 degrees off, while the westward-driving one could be facing the same direction as the main surface. Since the device just needs to "return to start" in the morning, then just follow the sun over the day)

I had considered something like that myself as a thought experiment. I also realized the sunset/sunrise problem that you noted. It was VERY satisfying to see you actually construct a working prototype. I wonder if (like an impact head lawn sprinkler) when the array gets to the sunset position, it might automatically reset to the sunrise position using some kind of limit switch. I have wanted to build a tracking solar array for my grandsons' fort, but didn't want to spend much. I think this could make a nice project to build with them, not just for them. Thank you!

Just angle the east panel more eastward. I did it to mine with east and west angled and it worked fine. Then I made one for my friend but the nut and bolt fell out of the west bracket on the way somehow, so it laid parallel with the main panel. I found the nut and bolt in the back of the truck when I got home. So I went back the next morning as the sun was coming up and watched it turn back east with no problem ... It worked just fine. You don't have to angle the west one ... it was a rectangular panel laying horizontal and the west panel didn't see the sun from the east. I put it back with the angle to make it look even. They are sundials ... they don't do good in heavy wind though lol.
