Photovoltaic system the outer edge. Electrically connected and mounted on a supporting structure, solar modules build a string of modules, often called solar panel. A solar array consists of one or many such panels. A photovoltaic array, or solar array, is a linked collection of solar modules. The power that one module can produce is seldom enough to meet requirements of a home or a business, so the modules are linked together to form an array. Most PV arrays use an inverter to convert the DC power produced by the modules into alternating current that can power lights, motors, and other loads.
Photovoltaic keyboard Photovoltaic keyboard A photovoltaic keyboard is a wireless computer keyboard that charges its batteries from a light source such as the sun or interior lighting, addressing a major drawback of wireless computer peripherals that otherwise require regular replacement of discharged batteries. The Logitech K750 has a set of photovoltaic cells on the top edge, charges in sunlight or under a standard bulb, can work up to three months in total darkness, and includes software to display battery charging status. It is a fullsized keyboard, including the usual movement keys and NumPad section on the right side, with low-profile keys much
