JUMTRACKER: TWO AXES SOLAR TRACKERS
The tracker is the equipment used to direct the photovoltaic panels to the Sun, so that the largest possible amount of solar radiation is captured and the production of energy is increased by more than 40% as opposed to with fixed systems.
In the JUMTRACKER models there is an innovative system of rolling platforms totally balanced on five supports for greater precision, regulated from points off the axis. Its stability, simplicity and capacity give the system the maximum safety, utility and economy, with which we get the best relation between quality and price (its cost is approximately 15% less than conventional trackers).
SAFETY
Due to its tested reliability, the constructive system adopted is the same as that used by the metallic supports of the electrical lines:
• Utilization of laminated surfaces
• Joints welded in the forms
• Joints screwed between forms
• Galvanized thickness of more than 50 microns (others available)
The stability of the assembly is obtained by means of a large structural support that is corners and one in the central shaft.
The structure has been measured to tolerate efforts in working position equivalent to winds of 125 Km/h at any position (can be calculated for faster winds): maximum pressures of 90 Kg/m² uniform distribution and 120-60 Kg/m² with imbalance.
The base is formed by six pillars and five triangular girders of equal dimensions. The simplicity of this geometry allows a very exact calculation of the structure, ensuring great safety regarding the true stresses that it can resist without suffering permanent deformations.
UTILITY
The trackers contain two boards at the front and another two at the back, positioned in terraces to avoid shades, thus obtaining a great power capacity (area of panels: 200 m2 in model 3B12 and 236 m2 in 3B13).
The position of the supports in “H” facilitates the adjustment of the structure to the irregularities of the track, allowing for admissible vertical displacements of 1 cm.
The symmetry of the structure ensures that all the wheels support the same load, obtaining a well balanced system.
The panels are placed inside trackers which are fitted to the door jambs by means of claspers. The system offers maximum flexibility and rapid installation.
The orientation in azimuth is obtained by means of a motor-system reducer that acts on two of the supporting wheels.
The movement of elevation has an analogous system acting on a spindle.
In both cases the relation between turns and displacements is very small, so great precision is obtained in the orientation of the panels.
The speed obtained in the order of 0,025º per second in azimut and 0,05º per second in elevation.
ECONOMY
Thanks to the simplicity of its components the maintenance is minimal. This, together with the productivity gained by the orientation of the panels, makes this tracker a very profitable piece of equipment.
The impact of the weight on the structure is minimal, in the order of 30 Kg per every m2 of panel.
The track is made with concrete of low plasticity, poured on armor fixed to the soil, with no need for formwork.
The whole structure is laminated, does not need special pieces, and all the principal components are finished from workshop. Its dimensions are adapted to conventional transport, thus simplifying the final assembly.
