A sunshade could potentially be one climate engineering method for mitigating global warming through solar radiation management, because internationally negotiated reductions in carbon emissions may be insufficient to stem climate change. [5] [6] Sunshades could also be used to produce space solar power, acting as solar power satellites ...
Solar cell fabric is a fabric with embedded photovoltaic cells which generate electricity when exposed to light. Traditional silicon based solar cells are expensive to manufacture, rigid and fragile. Although less efficient, thin-film cells and organic polymer based cells can be produced quickly and cheaply.
SunSetter's primary product lines are awnings, but the company also manufactures retractable screens, solar shades, flagpoles, and mats. [citation needed] The company currently produces four different types of deck and patio awnings (including motorized and manual awnings); customers choose the color and size. [1]
Shade screens utilize acrylic canvas or a mesh fabric, which allows some view-through while blocking the sun's rays. The roller at the top may be hand-cranked or motorized. [5] The fabric is gravity-fed, with a weighted bottom rail pulling the fabric down between guide rails [broken anchor] or guy wires.
UPF (ultraviolet protection factor) represents the ratio of sunburn-causing UV without and with the protection of the fabric, similar to SPF (sun protection factor) ratings for sunscreen. While standard summer fabrics have UPF ~6, sun protective clothing typically has UPF ~30, which means that only 1 out of ~30 units of UV will pass through (~3%).
An 18×14 mesh has become standard; 16×16 was formerly common and other common sizes are 18×18 and 20×20. For comparison, a typical screen in a clothes dryer has a nylon 23x23 mesh screen. Fiberglass solar screens provide over 75% of UV protection, by using thicker strands and a closer mesh than regular 18x14 fiberglass window screening ...
