Building-Integrated Photovoltaics (BIPV)
Building-integrated photovoltaic materials are manufactured with the double purpose of producing electricity and serving as construction materials. They can replace traditional building components, including curtain walls, skylights, atrium roofs, awnings, roof tiles and shingles, and windows.
Concentrating photovoltaic collectors use devices such as Fresnel lenses, mirrors, and mirrored dishes to concentrate sunlight onto a solar cell. Certain solar cells, such as gallium arsenide cells, can efficiently convert concentrated solar energy into electricity, allowing the use of only a small amount of semiconducting material per square foot of solar collector. Concentrating collectors are usually mounted on a two-axis tracking system to keep the collector pointed toward the sun.
I just launched a new solar energy site to complement this blog.
There’s not much content right now, but I got lots of good stuff planned.
