    en.wikipedia.org/wiki/Space_Solar_Power...

    Solar Dynamic (SD) power systems concentrate sunlight into a receiver where the energy is transferred to a heat engine for conversion to electrical power. Brayton heat engines utilize a turbine, compressor, and rotary alternator to produce power using an inert gas working fluid. Such a system was devised for use on an SSP. [citation needed]

  3. Solar inverter - Wikipedia

    en.wikipedia.org/wiki/Solar_inverter

    Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...

    en.wikipedia.org/wiki/Light_tube

    The 3M company developed a system based on optical lighting film [36] and developed the 3M light pipe, [37] which is a light guide designed to distribute light uniformly over its length, with a thin film incorporating microscopic prisms, [26] which has been marketed in connection with artificial light sources, e.g. sulfur lamps.

    en.wikipedia.org/wiki/Space-based_solar_power

    Construct technology development and demonstration roadmaps for critical space solar power (SSP) elements. SERT went about developing a solar power satellite (SPS) concept for a future gigawatt space power system, to provide electrical power by converting the Sun's energy and beaming it to Earth's surface, and provided a conceptual development ...

  6. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    Solar panels are also known as solar cell panels, solar electric panels, or PV modules. Solar panels are usually arranged in groups called arrays or systems . A photovoltaic system consists of one or more solar panels, an inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as ...

  7. Double envelope house - Wikipedia

    en.wikipedia.org/wiki/Double_envelope_house

    A double envelope house is a passive solar house design which collects solar energy in a solarium and passively allows the warm air to circulate around the house between two sets of walls, a double building envelope. This design is from 1975 by Lee Porter Butler in the United States.

  8. Passive solar building design - Wikipedia

    en.wikipedia.org/wiki/Passive_solar_building_design

    A heat pump might use 1 J for every 4 J it delivers giving a COP of 4. A system that only uses a 30 W fan to more-evenly distribute 10 kW of solar heat through an entire house would have a COP of 300. Passive solar building design is often a foundational element of a cost-effective zero energy building.

  9. Solar Umbrella house - Wikipedia

    en.wikipedia.org/wiki/Solar_Umbrella_house

    Passively adapted to the temperate-arid climate of southern California, the major design feature of the Solar Umbrella is a shading solar canopy.Rather than deflecting sunlight, this contemporary solar canopy uses 89 amorphous photovoltaic panels to transform the sunlight into usable energy, providing 95% of the residence's electricity.
