2. Solar power in the United States - Wikipedia

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

   In 2006 investors began offering free solar panel installation in return for a 25-year contract, or power purchase agreement, to purchase electricity at a fixed price, normally set at or below existing electric rates. [181][182] By 2009 over 90% of commercial photovoltaics installed in the United States were installed using a power purchase ...

   Prices for thin-film solar cells and for c-Si solar panels were around $.60 per watt. [ 42 ] Module and cell prices declined even further after 2014 (see price quotes in table).

4. Levelized cost of electricity - Wikipedia

   en.wikipedia.org/wiki/Levelized_cost_of_electricity

   Average unsubsidized levelized cost of energy. With increasingly widespread implementation of sustainable energy sources, costs for sustainable have declined, most notably for energy generated by solar panels. Data source is Lazard. [1] The levelized cost of electricity (LCOE) is a measure of the average net present cost of electricity generation for a generator over its lifetime. It is used ...

5. 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 ...

6. Photovoltaic system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_system

   Solar PV system on Zugspitze, Germany's highest mountain-top. A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into ...

7. Solar cell - Wikipedia

   en.wikipedia.org/wiki/Solar_cell

   A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [ 1 ] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.
