Comprehensive overview of the Solar System. The Sun, planets, dwarf planets and moons are at scale for their relative sizes, not for distances. A separate distance scale is at the bottom. Moons are listed near their planets by proximity of their orbits; only the largest moons are shown. Only the largest moons are shown. Date: 29 May 2018 ...
The Solar System remains in a relatively stable, slowly evolving state by following isolated, gravitationally bound orbits around the Sun. [28] Although the Solar System has been fairly stable for billions of years, it is technically chaotic, and may eventually be disrupted. There is a small chance that another star will pass through the Solar ...
Photovoltaic array – a power generating unit of modules and panels that convert solar radiation or energy from the sun into electricity. Photovoltaic cell – Photovoltaic module – Photovoltaic plant – Photovoltaic system (PV system) – uses solar panels to convert sunlight into electricity.
The Solar System is a gravitationally bound system consisting of the Sun and the celestial bodies that orbit it. After the Sun, the largest objects in the Solar system are the eight planets, consisting of the four gas and ice giants as well as the four terrestrial planets .
For example, since the Sun formed, some of the helium and heavy elements have settled out of the photosphere by diffusion. As a result, the Solar photosphere now contains about 87% as much helium and heavy elements as the protostellar photosphere had; the protostellar Solar photosphere was 71.1% hydrogen, 27.4% helium, and 1.5% metals.

Solar energy is clean and renewable. Solar architecture is designing buildings to use the sun's heat and light to maximum advantage and minimum disadvantage, and especially refers to harnessing solar power. It is related to the fields of optics, thermics, electronics and materials science. Both active and passive strategies are involved.
New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) account for another 3% and are growing very rapidly. [1] Total investment in renewable energy reached $244 billion in 2012. The top countries for investment in recent years were China, Germany, Spain, the United States, Italy, and Brazil.
