  3. Rooftop solar power - Wikipedia

    en.wikipedia.org/wiki/Rooftop_solar_power

    In the mid-2000s, solar companies used various financing plans for customers such as leases and power purchase agreements. Customers could pay for their solar panels over a span of years, and get help with payments from credits from net metering programs. As of May 2017, installation of a rooftop solar system costs an average of $20,000.

    For example, when the sun is more than about 60° above the horizon (<30°) the solar intensity is about 1000 W/m 2 (from equation I.1 as shown in the above table), whereas when the sun is only 15° above the horizon (=75°) the solar intensity is still about 600 W/m 2 or 60% of its maximum level; and at only 5° above the horizon still 27% of ...

    en.wikipedia.org/wiki/Pyranometer

    The solar energy industry, in a 2017 standard, IEC 61724-1:2017, [3] has defined the type and number of pyranometers that should be used depending on the size and category of solar power plant. That norm advises to install thermopile pyranometers horizontally (GHI, Global Horizontal Irradiation), and to install photovoltaic pyranometers in the ...

  6. Passive solar building design - Wikipedia

    en.wikipedia.org/wiki/Passive_solar_building_design

    In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.

  7. Photovoltaic mounting system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_mounting_system

    Photovoltaic mounting systems (also called solar module racking) are used to fix solar panels on surfaces like roofs, building facades, or the ground. [1] These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called BIPV ). [ 2 ]
