A system for collecting solar energy to be stored and distributed in a multi-unit building to be used for heat and electricity, comprising one or more solar energy collectors, one or more sunlight concentrating mirrors, photovoltaic panels, a heat mass storage area, and thermos siphoning to distribute heat energy throughout the building in conjunction with radiant heating technology.

To position a solar oven radiation collection device, a structural extension assembly extends in a radial direction with respect to a structure. A moveable transport provides linear movement of the solar oven radiation collection device along an axis of the structural extension assembly. A linear deploy electric motor is used to control linear movement of the solar oven radiation collection device along the axis of the structural extension assembly. A solar altitude electric motor is used to adjust orientation of the solar oven radiation collection device to take into account changes in solar altitude with respect to time. A solar azimuth electric motor is used to adjust orientation of the solar oven radiation collection device to take into account changes in azimuth with respect to time.

The invention relates to a passive tracking device for tracking the position of the sun, which comprises a hollow parallelepiped casing through which the solar radiation entering through a first lens located at the upper end of the parallelepiped casing passes towards a discriminating reflector arranged at the lower end of the same casing; the tracking device redirects as much incoming radiation as possible towards side chambers for absorbing radiation, heating a working fluid contained in the side chamber; producing a volumetric expansion in the working fluid that, communicating with shafts for the rotation of the tracking device, allows the orientation with the normal/perpendicular position with respect to the position of the sun, and to guide the alignment direction of other tracking devices for collecting energy in devices for collecting photovoltaic and/or thermal energy that are mechanically connected to the tracking device.

A system and method for tracking the sun with a heliostat mirror is disclosed. The solar tracking system comprises: a camera configured to capture high dynamic range images of the sky, a plurality of cameras configured to capture images of the heliostat mirror, and a tracking controller. The images of the heliostat mirror include reflections of the sky. The tracking controller is configured to generate a circumsolar radiance map characterizing the brightness of at least a portion of the sky with the high dynamic range images. During tracking operations, the tracking controller is configured to estimate an orientation of the heliostat mirror; calculate coordinates of the portions of sky in the reflections in the heliostat mirror; estimate brightness levels of portions of sky in the reflections of the heliostat mirror based on the calculated coordinates and the radiance model; determine brightness levels of portions of sky in the reflections of the heliostat mirror based on the images from the plurality of cameras; generate an error measurement characterizing a difference between the brightness level estimated from the radiance model and the brightness level determined from the images of the heliostat mirror; search for an orientation angle of the at least one mirror that minimizes the error measurement; and re-orient the at least one mirror based on the orientation angle that minimizes the error measurement.
