Description

Integrally-wound storage type solar cell panel

Technical Field

The utility model relates to a satellite is with flexible solar cell panel technical field, concretely relates to whole formula solar cell panel of accomodating around axle.

Background

Solar arrays relate to structures attached to certain spacecraft vehicles or satellites to power the spacecraft, solar arrays take up little space to store for easy shipping and launching, and photovoltaic solar panels can be deployed in space to convert solar energy into kinetic energy needed to operate the spacecraft.

Power systems for space applications face a number of design constraints, including criteria to minimize weight, minimize storage volume, maximize life-to-end-of-life performance, and minimize cost.

In the prior art, solar cells can be mounted to a lightweight flexible substrate or blanket rather than a large heavy rigid honeycomb panel. Various flexible solar cell cover substrates have been used, such as those made of fiberglass mesh or thin polymer sheets, to which numerous crystalline solar cells are bonded.

Flexible Photovoltaic (PV) blanket solar cell arrays are typically limited to crystalline solar cells packaged on long continuous rolls or pleated and folded stacks that are connected and unfolded by a separate deployment arm actuator, hub structure or other deployable structure requiring an external motor power supply.

Solar cells are by far the most expensive component of a solar cell array. Since both system cost and quality increase directly with the number of solar cells used, there is considerable economic incentive to reduce the number of solar cells carried by the spacecraft. To reduce the cost of the solar cell array and more effectively protect the solar cell array from radiation exposure, reflective or refractive concentrator elements may be used to reduce the number of cells.

By using relatively inexpensive Fresnel lens optics to collect and focus sunlight onto smaller solar cells, the cost and weight of the cells for an equivalently powered solar cell array is significantly reduced. By using very efficient cells, the required array area is minimized, reducing the overall system weight.

The lens assemblies and lens banks are thin lightweight rollable curvilinear elements, flat or arched, made of flexible DC93500 silicone elastomer material, with a protective front side coating, mounted directly above the solar cell bank and positioned precisely so that it captures incident solar radiation (light) and refracts it onto the solar cell row directly below to increase the illumination of the cells.

For example, US patent No. US9450131 uses a large amount of flexible material to achieve curling of the whole, but it can only achieve one-way winding, and when the solar substrate is too long, the pressure on the solar cell array after winding is too large.
