摘要:
This invention is about a method and apparatus for fabricating large scale stationery parabolic solar collector. The method involves use of a robot like apparatus for determining locations and height of support piles to be staked to the ground such that the tips of the piles define contour and shape of a parabolic collector. The reflective panels installed on the support piles form a parabolic shaped mirror which reflects the sun's rays to a well defined focal point. The method of construction is scalable and can be used for fabricating small size parabolic collectors as well as large scale ones. The construction apparatus and method of operation are also used for periodic cleaning of solar collector in a practical and fast manner.

A solar heat collecting device with high heat collecting efficiency is provided. A single-axial solar tracking type reflection mirror group 20 is disposed with each long axis facing in the same direction. A first dual-axial solar tracking type reflection mirror group 30 and a second dual-axial solar tracking type reflection mirror group 40 are disposed side by side in a direction orthogonal to the long-axis direction of a single-axial solar tracking type reflection mirror 21. The single-axial solar tracking type reflection mirror group 20 is disposed sandwiched between the first dual-axial solar tracking type reflection mirror group 30 and the second dual-axial solar tracking type reflection mirror group 40. Each mirror group sends to a heat collecting unit 10, the solar heat received while tracking the position of the sun single-axially or dual-axially.

A system for collecting solar energy using a plurality of energy collection elements arranged in a planar array within a stationary base structure, each comprising: an energy capture unit with optical means of focusing directional sunlight parallel to its axis onto one or more sunlight-to-electricity converters within itself, and means of sensing divergence of its axis from the sun's direction; and an angular positioning unit that orients said capture unit about two nested axes by slidably mounting two arcuate tracks in opposed and perpendicular arcuate slots, a convex track within said energy capture unit and a concave track within said base structure, each said slot equipped with a drive apparatus that engages its respective track and moves the positioner along it. The invention provides methods for determining the shapes and arrangement of such elements so as to maximize aperture efficiency while preventing collisions of adjacent elements.

The present invention relates to a solar energy collection apparatus and design method. In particular, the invention provides a solar energy collection apparatus incorporating one or more reflectors and a solar collector for receiving incoming solar radiation, including reflected radiation from the one or more reflectors, wherein the one or more reflectors and the collector are oriented according to a pre-calculated offset length and offset angle based at least on the latitude of the apparatus. The invention further provides a computer-implemented method of designing a solar collection apparatus including determining the optimal offset length and offset angle between the one or more reflectors and the collector for a given latitude and other inputs.

摘要:
Disclosed is technology pertaining to a device and method for photovoltaic power generation using a photoelectric effect, and particularly a device and method for producing more electric power from a photovoltaic panel of the same area by coupling relatively inexpensive additional devices (flat mirrors, a rotation mechanism, and a cooling system) to the expensive photovoltaic panel. The device for photovoltaic power generation includes: a frame; a photovoltaic panel arranged on the frame such that a light receiving surface is perpendicular to an incident direction of sunlight with the back thereof against the sun; two or more flat mirrors which are arranged on the frame and reflect the incident sunlight to the light receiving surface of the photovoltaic panel; a rotation mechanism for tracking the sun such that the light receiving surface of the photovoltaic panel is perpendicular to the incident direction of the sunlight by rotating the frame in a biaxial direction; and a supporting structure for supporting the frame and the rotation mechanism.
摘要:
A system and method for providing real time control of a heliostat array or CPV/PV module that reduces actuation cost, the disclosure reduces the fixed cost of calibrating and repositioning an individual surface. This simultaneously removes the core engineering assumption that drives the development of large trackers, and enables a system and method to cost effectively track a small surface. In addition to lower initial capital cost, a small heliostat or solar tracker can be pre-assembled, mass-produced, and shipped more easily. Smaller mechanisms can also be installed with simple hand tools and do not require installers to rent expensive cranes or installation equipment.
摘要:
Mixed heliostat field combining, in the same field, heliostats of different sizes and/or with different types of facets, all of them having at least one facet and being canted or not, and either having spherical, cylindrical, flat or quasi-flat (spherical with a high curvature radius) facets, such that the solar field is optimised in order to minimise shadows and blockages between heliostats, as a result of correct positioning of the heliostats in the field.
