The use of small solar cells for automatic aeration of systems is currently unavailable due to the tow efficiency of solar cells. With my invention, this would become possible. With this innovative design and setup, a very cost-effective automatic solar air pump can be used in different applications and systems. The solar air pump can work even on cloudy days and would have stored energy to work at night.

Solar Cells and Panels have power absorption limitations and are less efficient if the Solar Panel is not tilted in right way to the Sun to absorb the maximum amount of Solar Energy. They are also limited and inefficient during cloudy and rainy days. Dust and shading also reduces the energy and power absorption of Solar Panels.

In a small-scale application, for example with a Solar Panel with an area of 5.5 inches×4.5 inches, it is normally very difficult for the Solar Panel to power gadgets and appliances.

I decided to first focus on the Air Pump system for aquariums, aquaponic systems, hydroponic systems, bore holes and Irrigation.

A method for the weight-dependent control of the internal pressure of a supporting body loaded by a weight load or payload, wherein the internal pressure is produced by means of an electric-motor-driven compressor, and the weight load or payload which is present and which acts on a supporting body in the form of a mass m.sub.Load under the effect of acceleration due to gravity g is determined in that a reduction and a subsequent increase in the internal pressure take place, wherein the increase in the internal pressure causes the position of an application point of the weight load or payload to change by a position difference Z, wherein:

during the increasing of the internal pressure by means of the compressor, the motor current I.sub.Load of the drive motor of the compressor is measured with a constant motor voltage U and integrated over the time of the increase in pressure, and the electrical work W.sub.Load which is necessary for the change in position is determined therefrom,

wherein the electrical work W.sub.Load the electrical work W.sub.Load is compared with a characteristic value of the electrical work W.sub.0 from a characteristic diagram, wherein the change in position Z, the difference in mass m and the difference in payload F.sub.Z are determined from the difference W between W.sub.Load and W.sub.0 and the mass m.sub.Load and the weight load or payload which is actually present as a result is determined therefrom.
