DE202005015572U1 - Solar slope for e.g. solar engineering facility, has solar useable surface with slope arrangement, where deviations of slope axes up to specific value and deviations of support points from one of edges of surface are protected - Google Patents

Abstract

The slope has a solar useable surface (4) with a slope arrangement that approaches a principle with small changes by adjusting support points away from a center of gravity (5) or shifting slope axes lying in a space into easy sloping positions and comparable light variation. Deviations of the axes up to 30 degree and deviations of the points up to 30 percent from one of edges of surface, are protected from the gravity.

Description

The Solar tilt is an invention for Solar technology systems for complete or partial alignment a surface of solar modules, to the sun without a rotation about the upright y-axis (1) perform. The goal is to have as large a usable area as possible low energy consumption freely in the room to tend towards the sun.

The Solar tilt can be used in photovoltaic power generation or in the photovoltaic Solar thermal for heat recovery be used.

Previous alignment systems rotate the entire apparatus with the full weight around the upright y-axis ( 1 ) to track the sun.

Other Appliances are placed obliquely aligned with a fixed axis and in addition tend an axis behind the sun.

At the solar tilt ( 1 ), the inclination to the sun is achieved by the fact that the usable area ( 4 ) in the horizontal x-axis ( 2 ) and the horizontal z-axis ( 3 ) about the focus ( 5 ) of usable area ( 4 ) is inclined.

conventional trackers consume more energy, because they in the tracking rotation the frictional resistance overcome the dead weight have to. Or they produce less energy because they are immobile Parts or stationary axes are limited in the tilting movement to the sun.

The Solarneige, however, oscillates in the Sonnennachführung always in balance to all sides in their own focus. That is, the solar tilt tends its useful surface in the tracking over the center of gravity such that there is always an equal counterweight movement. Thus, the, the useful surface aligning power plants with low forces and minimal energy consumption, such as. In 3 also with a simple cable or chain hoist that can be diagonally coupled, and thus with 2 small motors ( 6 ) ( 7 ), which align solar tilt easily.

A further advantage of the solar tilt is that it can effectively reach a large area even to the sun ( 8th ) ( 2 ) can incline when the inclination in both axes is only about 30 degrees to the sun.

In This inclination range can be mostly (depending on the position of the Earth latitude) about 95% of the energy yield of a sunny day can be achieved. This means, that in construction for a flat mode of operation succeeds here a lot of energy yield. Thereby can additionally Motor energy and assembly costs are saved. Due to the lower inclination The solar tilt is particularly suitable for large-scale application on flat Planes or flat roofs.

at usual Module superstructures on flat roofs can through the shadow of the modules set up in rows, they effect each other, only about one third of the roof area are used. The solar tilt can cover the whole area use and even over the roof protrude and the usable area easily over the Enlarge the roof. So The energy yield on the same flat roof can already be done three times without tracking be so high. Consider then additionally the inclination tracking and the possibility a supernatant about that Roof, so the energy output with the solar tilt can be on the same Roof very easy to be 6 times bigger as with conventional Attachments.

One Another advantage is that when lasting flat usage possibilities The wind resistance is lower than in conventional systems and emerging Wind the surface quickly completely flat to the ground can be put to zero degrees so that the wind no attack surface to offer more.

Compared with flat mounted fixed module surfaces, the solar tilt also has the advantage that it can be easily tilted in the rain and thus optimally use the self-cleaning of the modules. In winter can be effected in the same way very energy-saving slipping of the snow. In addition, conventionally raised in rows modules must be kept on flat roofs by weights on the roof, as a tapping of the flat roof skin would make the roof leaking. The solar tilt, however, only needs a single mounting point on the roof, which is structurally easier to control and z. B. easier sealed or supported from below or even by a frame construction with the burden completely on the outer walls ( 3 ) can be moved. As a result, the solar tilt is easier to mount on previously unsuitable for solar use roofs and areas.

Claims (1)

To be protected is the solar tilt, which is characterized by a tilt arrangement of the solar utility area in the center of gravity with the inclination to have the two axes lying in space. This should also be protected at the same time arrangements that come close to the principle with small changes, for example, by slight displacement Movements of the support point away from the center of gravity or displacements of the two tilting axes in the room in slight inclinations and similar slight changes. Deviations of the tilting axes should be protected up to 45 ° and deviation of the support point up to 30% from one of the edge sides of the solar utility area away from the center of gravity.
