The invention relates to solar energy, in particular for highly efficient solar energy modules concentrator to produce electrical energy.

The practical implementation of the photoelectric conversion method highly concentrated solar radiation, the problem of designing and creating highly effective, cheap and simple to manufacture selenocentric of solar concentrators.

This need is particularly relevant when used in large-scale solar energy is scarce and expensive semiconductor materials, such as gallium arsenide and solid solutions based on it.

Known solar photovoltaic module with parabolic trough concentrator containing a receiver located at the focal region with a cooling device, and a tracking system (Zh. Photovoltaic conversion of concentrated solar radiation. Leningrad. The science. 1989. S).

The disadvantages are the complexity of the manufacture of parabolic trough concentrator with double curvature shape forming reflecting surface curves of the second order (the circle and the parabola).

The closest in technical essence of the present invention is a solar PV project m is a module with two-mirror siliconnitride-Cassegrain (DSC), developed by TRW (USA) according to the structural scheme of the DSK and the design scheme DSC (Zh. Photovoltaic conversion of concentrated solar radiation. Leningrad. The science. 1989. S, S, S).

Known siliconnitride two-mirror system Lasergene (DSC) consists of a helical surfaces of rotation of the second order, namely, paraboloid and hyperboloid.

The optical scheme of the mirror concentrating systems in General differs in form forming a reflective surface (straight line, curve of the second order, and others). The shape of the generatrix of the reflective surface of the paraboloid has a double curvature and consists of a circular curve 2-th order and the parabola curve 2-th order. The shape of the generatrix of the reflective surface of the hyperboloid has a double curvature and consists of a circular curve 2-th order and the hyperbola curve 2-th order.

A significant drawback of the known solar module with DSK is the difficulty in making two hubs of various shapes with axial surfaces of rotation of the second order.

The objective of the invention is simple to manufacture, yet highly efficient and cheap siliconnitride system for solar photovoltaic modules.

In use of the present invention is created cheap and so the flock in the manufacture of high-performance siliconnitride system for PV module consisting of two hubs one form and having only one curvature (circle, curve 2-th order), which simplifies their manufacture.

The above technical result is achieved by the fact that in the proposed solar PV modules in the hub that contains the primary and secondary mirror concentrators, sensor tracking, the receiver located at the top of the primary hub perpendicular to its optical axis with a cooling device, in the Central part of the primary conical hub with a through hole coaxially its optical axis is placed sensor tracking, located inside the cooling unit with two rasciausko conical tip at its top and at its base, while the inner part of the cooling device has a cylindrical hole, and a receiver mounted on its outer side between the conical tip having an external surface and performs the functions of the secondary conical hub, and the Foundation of the primary conical hub, sensor tracking and cooling unit with a secondary conical hub fixed on the heat sink with cylindrical holes, and the shape of the generatrix of the conical surface of the hub has a single curvature and consists of OCD is gnosti - curve 2-th order and a straight line.

The invention is illustrated by figure 1 and 2.
