    On June 20, 1979, 32 solar water heating panels were placed on the roof of the West Wing.The panels were made by InterTechnology/Solar Corp. from Warrenton, Virginia and installed by Hector Guevara of Alternate Energy Industries Corp. [2] At the dedication ceremony for the panels, President Carter said, "In the year 2000 this solar water heater behind me, which is being dedicated today, will ...

  3. Soiling (solar energy) - Wikipedia

    en.wikipedia.org/wiki/Soiling_(solar_energy)

    Solar panel design: Solar panels can be designed to minimize the impact of soiling. This includes the use of smaller solar cells (e.g. half-cells), panels without frames (avoiding dirt collection at the edges), or alternative electrical configurations (e.g. more bypass diodes that allow current to pass the soiled parts of the panel). [ 1 ]

  4. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.

    The solar panel issue goes to the core of one of Biden’s arguments for re-election: that his economic policies have begun transforming the U.S. energy economy while combating climate change.

  6. Solar power in the United States - Wikipedia

    en.wikipedia.org/wiki/Solar_power_in_the_United...

    In a feed-in tariff model, the government sets the value for the electricity produced by a solar facility. If the level is higher, more solar power is built and the program is more costly. If the feed-in tariff is set lower, less solar power is built and the program is ineffective. The problem with SRECs is a lack of certainty for investors.

    On January 23, 2018, news outlets announced that Trump had imposed tariffs on solar panels produced outside the United States. The tariffs initially start at 30% and will gradually fall to 15% in four years. [57] [58] The first 2.5 gigawatts of solar cells imported each year will be exempted from the tariff. [59]

  8. Solar controller - Wikipedia

    en.wikipedia.org/wiki/Solar_controller

    The simplest solar controller circuit uses a comparator with two temperature inputs, one at the solar panel and one at the thermal store's heat exchanger, and an output to control the pump. Commercial controllers use a microprocessor usually with a LCD display and simple user interface with a few pushbuttons.

  9. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    Solar air heating is a solar thermal technology in which the energy from the sun, solar insolation, is captured by an absorbing medium and used to heat air. Solar air heating is a renewable energy heating technology used to heat or condition air for buildings or process heat applications.
