Solar Panel
A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photovoltaic system or solar array. Solar panels capture sunlight as a source of radiant energy, which is converted into electric energy in the form of direct current (DC) electricity. Arrays of a photovoltaic system can be used to generate solar electricity that supplies electrical equipment directly, or feeds power back into an alternate current (AC) grid via an inverter system. History In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by the French physicist Edmond Becquerel. Though these initial solar panels were too inefficient for even simple electric devices, they were used as an instrument to measure light. The observation by Becquerel was not replicated again ...

Australia
Australia, officially the Commonwealth of Australia, is a sovereign ''Sovereign'' is a title which can be applied to the highest leader in various categories. The word is borrowed from Old French , which is ultimately derived from the Latin , meaning 'above'. The roles of a sovereign vary from monarch, ruler or ... country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. With an area of , Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical Forests of Australia, rainforests in the north-east, and List of mountains in Australia, mountain ranges in the south-east. The ancestors of Aboriginal Australians began arriving from south east Asia approx ...

Ellipse
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. It generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity e, a number ranging from e = 0 (the limiting case of a circle) to e = 1 (the limiting case of infinite elongation, no longer an ellipse but a parabola). An ellipse has a simple algebraic solution for its area, but only approximations for its perimeter (also known as circumference), for which integration is required to obtain an exact solution. Analytically, the equation of a standard ellipse centered at the origin with width 2a and height 2b is: : \frac+\frac = 1 . Assuming a \ge b, the foci are (\pm c, 0) for c = \sqrt. The standard parametric equation is: : (x,y) = (a\cos(t),b\sin(t)) \quad \text \quad 0\leq t\leq 2\pi. Ellip ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signa ...

Broulee
Broulee is a town on the south coast of New South Wales between Batemans Bay and Moruya. At the , the town had a population of 1,717. Just off the beach is Broulee Island, currently joined to the mainland, but in past years the connecting spit has been covered by water, at times a very deep navigable channel with a strong current. The first harbour in the area south of Batemans Bay was established at Broulee behind what is now known as the island. Although settlement had already commenced on the shores of the nearby Moruya River, it was not easily navigable due to a sandbar at its mouth. History The Broulee area was surveyed and gazetted in 1837, a town plan made by James Larmer in 1839, and land sales commenced in 1840. At that time a post office was opened with mail being delivered each week over the mountains from Braidwood. Henry Clarke took up farming in the Broulee area in the 1840s after emigrating from Ireland. The first court in the district was established als ...

Batemans Bay
Batemans Bay is a town on the South Coast region of the state of New South Wales, Australia. Batemans Bay is administered by the Eurobodalla Shire council. The town is situated on the shores of an estuary formed where the Clyde River meets the southern Pacific Ocean. Batemans Bay is located on the Princes Highway (Highway 1) about from Sydney and from Melbourne. Canberra is located about to the west of Batemans Bay, via the Kings Highway. At the 2021 census, Batemans Bay had a population of 17,519. It is the closest seaside town to Canberra, making Batemans Bay a popular holiday destination for residents of Australia's national capital. Geologically, it is situated in the far southern reaches of the Sydney Basin. Batemans Bay is also a popular retiree haven, but has begun to attract young families seeking affordable housing and a relaxed seaside lifestyle. Other local industries include oyster farming, forestry, eco-tourism and retail services. History Indigenou ...

Battert
The Battert is a hill, , on the western edge of the Northern Black Forest north of Baden-Baden in Germany. On its western slopes are the ruins of Hohenbaden Castle (the ''Altes Schloss'' or "Old Castle"), on the southern side is the climbing area and nature reserve called the Battert Rocks (''Battertfelsen''). On the hill ridge are the remains of a circular rampart, probably built by Celtic settlers. On the eastern side lies the village of Ebersteinburg. The Battert is a destination for ramblers and climbers all year round, heading for the 15–60-metre-high ''Battertfelsen''. Above and below the rock face is a footpath around the rocks. The red rock face is visible from far off and may be easily reached on the road to the ruins of Hohenbaden or from a car park near Ebersteinburg. Geology Consisting of sediments of Rotliegend, the Battertfelsen were formed about 251-299 million years ago. By contrast with their immediate environment, the rocks of the Battertfelsen silici ...

Mains Electricity
Mains electricity or utility power, power grid, domestic power, and wall power, or in some parts of Canada as hydro, is a general-purpose Alternating current, alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electric grid in many parts of the world. People use this electricity to power everyday items—such as domestic appliances, televisions and lamps—by plugging them into a wall outlet. The voltage and utility frequency, frequency of electric power differs between regions. In much of the world, a voltage (nominally) of 230 volts and frequency of 50 Hz is used. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other combinations exist, for example, 230 V at 60 Hz. Travellers' portable appliances may be inoperative or damaged by foreign electrical supplies. Non-interchangeable AC power plugs and sockets, plugs and sockets in differen ...

Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lens (optics), lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have Growth of photovoltaics, grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new gene ...
