Modular Solar Tracker

About Solution

The modularity of solar panels allows to reduce the consumption of steel on the frame.

For example, large solar panels on two pillars are rotated only horizontally, as when turning vertically - a strong wind blows it off.

But if a large panel is divided into several parts, then the wind pressure on the axis of each of them will be less.

Thus, the total area of all panels can be increased by 4-5 times. That is, the consumption of material on the poles is reduced.

One motor can rotate the panels in both directions with a special gearbox, which is switched by electromagnetic clutches.

If the consumption of magnetic couplings is too large, the volume of the motors may be two. But such a compact arrangement of engines also saves material.

This concept of a compact arrangement of two motors or one motor with two gearboxes can be used on solar panels with one support.

In addition, the solar panels can be covered with a special glass with a structure having a configuration of the Abbe prism, which ensures a constant deviation of light by 90 degrees.

The bottom pole with a large horizontal gear is fixed to the ground stiffly. Thus, the axis with the motor can rotate around it, acting on the horizontal ring gear by means of a pinion from the reducer.

And the adjustment of the tilt of the panel is carried out by means of another small gear from another gearbox.

Similar gearboxes can move huge steel gates with large dimensions. In this case, the dimensions of the gearboxes themselves are small.

As an example, we have chosen a gearbox with a large decreasing rate. This provides a low power of the motor and therefore very little power consumption.

As a basis for our gear used schemes tested on escalators.

Such a gearbox displaces several tens of tons of iron and several hundred people, although the motor power averages 150 kilowatts - like a small jeep.

Consequently, to move a load of 500 kg, still balanced with axes, no more than 30 watts are required.

The large gear ratio of the gearbox ensures very high accuracy. Even if the motor is normal, then such a high accuracy will still be maintained.

But the stepping motor will provide even greater accuracy. When the stepping motor turns only 5 degrees, the track will be moved 0.5 degrees. An even greater gear ratio is possible.

The price of this gearbox will be much lower than others. One motor is cheaper than two, and the combined gearbox requires much less detail.

The consumption of materials for this gear will also be less than in normal cases.

Installation costs will be less than in other cases, since fewer parts are installed.

The gearbox has two worm gears for each axle - so the wind can not turn the solar panel.

This innovation became the finalist of the RMD competition:
