▶️Introduction
Solar trackers can be manually, passively or actively controlled (actuated).
Solar trackers are split into three main types, these are the horizontal, vertical and dual axis types.
How Dual Axis Solar Panels Work
Hydraulic cylinders are used to adjust the position of the solar tracker in order to follow the sun on a north to south axis and east to west axis. An anemometer is used to measure the wind speed and a solar sensor detects the level of solar radiation (sunlight). The tracker directs itself actively towards the sun in order to harness the maximum amount of energy possible.

A most excellent video and graphic CAD display. I am interested in going solar for a small cabin that I built, and because I am in a higher latitude location, it only makes perfect sense to go with a dual tracker system due to the changes in sun location in the various seasons (4 of them). Yes, it may cost more, but if you can eliminate most of the costs by being able to do the fabrication yourself, then it only makes sense to go with that design that will give you the most efficiency during the various seasons. You really have to weigh your options and do your homework before considering such a system. Thanks for sharing! Cheers!

When you look at dual axis solar panels and whether or not they are worth the extra cost, don't just consider "40% more yield vs 100% more cost". The power from solar panels are generally needed the most in the morning and evening. So that extra 40% is mainly obtained where you would get very little production with a fixed panel. The real worth of each kWh is much more, when the supply-demand balance is such that there isn't enough supply. That would be directly financially realised in grid tie solutions where the price paid varies with supply-demand. But also for island systems, where batteries back up at night, you are interested in keeping the batteries charged up until as late as possible, while also be able to recharge them in the morning, as early as possible. The savings in battery capacity will in many cases make up for the added cost of a dual axis system.

Dear b74a, your calculation is wrong. The cost of a MAX® (Multiple-AXis) tracker of e.g. 100 USD more to a FiX® (FiXed sub-construction) is probably 10 % - 15% more costs on the total system. The total system includes beside the construction, also all panels, inverters, cables, collector boxes, technical planning as also EPC (Engineering - Procurement - Controlling) costs. But on the annual revenue, a MAX® brings 145% , while the FiX® has only 100% of yearly electric production. On a long-term of 20 or more years, it is better to use MAX® , also called dual-axis, then not. With this system of MAX®, our company SOWiWA® GROUP is installing in Eastern Europe more than 1 GW of Photovoltaic in the next 5 years.

@qwiklok

Smart. learned a lot. thanks. My comment would be to have the East West orientation on a rotating column so the entire array rotates. Where i am located, central BC, the E W change is about 270 degrees, a whopping difference in summer. In winter, the change might be 120. So to rotate makes more sense. The up and down is at least 70 degrees in summer, maybe 30 in winter. With my 2 panels of 315 watts each, this makes a lot of senses because i need power immediately in the morning and to stock up late in the evening. the wind speed sensor is damn smart, so the panels flatten out in windy days . never thought of that. I'm thinking of a scrapped old big satellite dish mechanism as the main hardware and mechanics. if it can support a dish 10' in diameter, then that would be excellent for say 3 large 300w panels. yes? Well done.

I like this vid, so am subscribing for more basics, and looking around for other good, practical references.

I'm so confused by this. You say that a "horizontal" tracker, which follows the sun's path from east to west through the day, rotates about a "north-south axis", which seems correct. But later you repeatedly use the term "north-south axis" to refer to motion that alters the slope of the module up and down to match solar altitude. What exactly do you mean by "north-south axis" a line that runs through the center of the module from south to north? If so, wouldn't that make the module rotate from east to west?

The intent is a small solar farm tied directly to the grid to sell the power to the electric company with minimum start up of around $5 to $7k v $50k plus. I am also considering a single axis to start with. I'll see what they have.

Hi Kevin Newell; "East West Axis Horizontal Tracking Mounts" are generally the least desirable type for small scale systems. The "North South axis" types are better. However the "Polar Axis" types are much more desirable for small scale systems. See some nice examples here: www.redrok.com/electron.htm#tripod The tripod types are easy to build and more robust than the ones mounted on a vertical post. Duane C. Johnson redrok@redrok.com

The need for electricity around the clock during the day to operate loads that require a long number of hours is what forces us to implement a base of moving panels with one or two axes, or you must design a double photovoltaic array in order to obtain, for example, at nine in the morning the electricity necessary to operate those loads and waste excess electricity at peak times.

Very intersting, seems like too much overhead for not that much gain, but what if you had 1 axis instead, the panel is donig the same moevement eveery day so is dual axis really necessary? one axis with a predetermined angle could give you almost the same amount of gain, not quite admittidely, but perhaps at 1/10 the cost of a dual axis system with about 95% of the gains with a 1 axis? A simple script for your area could move it at the right time with no need for tracking overhead either further bringing the cost down. Just the hardware for movement of 180 degrees. And now you could afford to put all your panels on 180 degree motors and perhaps would want smaller panels to mulitply the efficiecny gain, as it would seem you should get more the more panels you can move, if they're smaller you can move more into optimal light.

Solar panels are not categorized (or manufactured) as 1 or 2-axis panels and non-moving panels. A panel is a panel. It is the mechanical track and pivot system that adds the cost. Although, maybe you didn't mean to communicate it the way you did?

If the sun isn't producing power, there's not much reason to track it. Like at night or in heavy clouds, the unit is dormant. Unless you mean when solar power output is insufficient, then there would be a small backup battery. This can be a stand alone battery located with the panels/tracker running off its own MPPT (controller).

Why does it cost 100% more for a pair of actuators?

I think you people should get a new dealer abroad, many companies make simple stuff more complicated and charge 10 times more than it should be.
@nickush7512
@nickush7512 5 лет назад
As far as off grid living is concerned, this video is super simplistic, and therefore (sorry mate, I do not want to diss you... ), inaccurate. As, and very often, more important than peak power, is the distribution of power throughout the day. In the darkest winter months, East to west tracking is not so important because (Northern hemisphere) the sun is rising in the South East and setting in the South West, with relatively little passage across the sky, however vertical alignment with the sun will make a significantly beneficial improvement. However, from mid February through mid October, to be able to maximise available power harvesting will make a big difference to the utility the panels provide... if you are not interested in being as kind to your batteries as you can, all this is not so relevant of course !! ... but if you are, and maybe you want or need to run some heavier loads when it is convenient for you to do so, rather than the position of the sun in the sky calling the shots, then it is useful to be able to have your panels orientated as norman (at right angles), give or take twenty degrees or so, to the sun as possible. I often get almost 50% of available power shortly after sunrise (I do have some visual obstructions to the SE, so sunrise is always an hour or so later than it would be at an unobstructed location, however it is still relatively low in the sky) and my setup is very far from ideal. So on a sunny day, continuous or intermittent, by early March through late October, I can use my maximum draw appliances from an hour or so after local sunrise through an hour so so before sunset, within reason, without putting a large load on my batteries, as a good chunk of the power that the inverter is supplying is coming straight off the pannels and therefore the batteries are not having to work so hard, thus, maintaining voltage. I tend not to impose a heavy draw within a couple hours before sunsett though, as I like my batteries to be fully charged well before. Basically, the length of both the useful day and of useful season is significantly extended. Now, if you are significantly dependent on that beautiful big yellow ball, you will know just how much significantly lengthened useful days and seasons are. Gain 40% but it is not worth it, better go go buy another panel instead might sound like a good idea, but if thought through and alowed to reach a logical destination, it does not provide a great deal of utility. Appreciate your batteties, be as kind to them as you can; track you panels both vertically and horizontally if you can; and enjoy the gift the sun is giving you for more hours per day and more months per year.

Dual axis solar panels; 40 % more energy for 100 % price increase. Not economical sustainable........I guess that depends on the demand of power during the day. If one could save or sell energy at times of the day with higher prices it might in fact be a GOOD deal. Where I live energy can often become almost free in the middle of the day. Meaning that I have no real economical use for making my own energy. In other times the price can go op several hundred percent.

Wow what a stupid reasoning that 100% more cost is not worth 40% more power. That's is a fantastic trade off,basically double the cost for almost extra half of power. DUDE that's not a disadvantage
