Photovoltaic mounting systemPhotovoltaic mounting systems (also called solar module racking) are used to fix solar panels on surfaces like roofs, building facades, or the ground. These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called BIPV). As the relative costs of solar photovoltaic (PV) modules has dropped, the costs of the racks have become more important and for small PV systems can be the most expensive material cost. Due to these trends, there has been an explosion of new racking trends.
Metal roofA metal roof is a roofing system featuring metal pieces or tiles exhibiting corrosion resistance, impermeability to water, and long life. It is a component of the building envelope. The metal pieces may be a covering on a structural, non-waterproof roof, or they could be self-supporting sheets. Lead and Copper have played a significant role in architecture for thousands of years (see: copper in architecture). Lead was one of the first and easiest metals to smelt and with a low melting point, could be easily formed watertight.
Cellule solaire à pigment photosensibleUne cellule solaire à pigment photosensible parfois appelée cellules Grätzel (en anglais, Dye-sensitized solar cell ou DSC) est un système photoélectrochimique inspiré de la photosynthèse végétale qui, exposé à la lumière (photons), produit de l’électricité. Elle est souvent désignée par l'acronyme dérivé de son appellation en anglais : dye-sensitized solar cell, DSC, DSSc voire DYSC). Les cellules Grätzel ont été nommées ainsi en référence à son concepteur, Michael Grätzel, de l’École polytechnique fédérale de Lausanne.
Space-based solar powerSpace-based solar power (SBSP, SSP) is the concept of collecting solar power in outer space with solar power satellites (SPS) and distributing it to Earth. Its advantages include a higher collection of energy due to the lack of reflection and absorption by the atmosphere, the possibility of very little night, and a better ability to orient to face the sun. Space-based solar power systems convert sunlight to some other form of energy (such as microwaves) which can be transmitted through the atmosphere to receivers on the Earth's surface.
Centrale solaire thermodynamiqueUne centrale solaire thermodynamique (ou centrale solaire thermique à concentration ou encore héliothermodynamique), en anglais CSP (pour concentrated solar power) est un site industriel qui concentre les rayons du Soleil à l'aide de miroirs afin de chauffer un fluide caloporteur, lequel sert en général à produire de l'électricité. Ce type de centrale permet, en stockant ce fluide dans un réservoir, de prolonger le fonctionnement de la centrale plusieurs heures au-delà du coucher du Soleil.

Un jardin sur toit ou jardin de toiture (ou « roof garden » pour les Anglo-Saxons) est n'importe quel type de jardin (jardin d'agrément, jardin potager, jardin écologique, éventuellement conçu de manière à être un élément ou gué d'un réseau de corridors biologiques) construit sur le toit d'un immeuble (habité ou non).
HipIn vertebrate anatomy, hip (or coxa in medical terminology; : coxae) refers to either an anatomical region or a joint. The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and overlying the greater trochanter of the femur, or "thigh bone". In adults, three of the bones of the pelvis have fused into the hip bone or acetabulum which forms part of the hip region. The hip joint, scientifically referred to as the acetabulofemoral joint (art.
Financial incentives for photovoltaicsFinancial incentives for photovoltaics are incentives offered to electricity consumers to install and operate solar-electric generating systems, also known as photovoltaics (PV). Governments offered incentives in order to encourage the PV industry to achieve the economies of scale needed to compete where the cost of PV-generated electricity is above the cost from the existing grid. Such policies were implemented to promote national or territorial energy independence, high tech job creation and reduction of carbon dioxide emissions which cause climate change.
Tellurure de cadmiumLe tellurure de cadmium (CdTe) est un matériau cristallin à structure cubique (de groupe d'espace F43m) composé de cadmium et de tellure. Il s’agit d’un semi-conducteur de la famille des II-VI. Le tellurure de cadmium est disponible commercialement sous forme de poudre ou sous forme de cristaux.
Solar power by countryMany countries and territories have installed significant solar power capacity into their electrical grids to supplement or provide an alternative to conventional energy sources. Solar power plants use one of two technologies: Photovoltaic (PV) systems use solar panels, either on rooftops or in ground-mounted solar farms, converting sunlight directly into electric power. Concentrated solar power (CSP, also known as "concentrated solar thermal") plants use solar thermal energy to make steam, that is thereafter converted into electricity by a turbine.
