While solar energy is used worldwide and even in space, the country with the most installed solar capacity is Germany. According to the European Photovoltaic Industry Association, Germany had approximately 35 GW of installed solar capacity by the end of 2013, almost double its closest competitor. China, Italy, Japan and the United States round out the top five countries with installed solar capacity.Know More
Solar energy is particularly well-suited for countries near the equator, since the sun's energy is most concentrated when it is directly overhead. Climate also plays a role, with hot, dry areas experiencing fewer bouts of precipitation that can block the sun's energy and reduce solar output. The best areas of the globe for solar energy include the Mojave Desert in the United States, the Sahara Desert in North Africa and much of the continent of Australia. Solar installations are particularly useful for remote areas of a country because power generation can happen on-site without the need for expensive and dangerous high-voltage electricity transmission lines.
Solar power is also a vital part of space-exploration programs. Long-duration space missions require a power source that can provide energy for instruments and systems over an extended period, and the sun provides plenty of free energy to power probes, satellites and other craft. The International Space Station features eight solar-panel wings that provide electricity for the station's systems and experiments.Learn More
The main cause of a short circuit is when two bare wires touch each other. This causes extra current to flow through the circuit, which can be dangerous. Two bare wires typically come into contact with each other when the insulation around the wires deteriorates.Full Answer >
A three-phase electrical wiring diagram is a clear, visual representation of a common method of power generation and distribution. Three-phase electrical wiring is the most common means of distributing alternating-current power on power grids world-wide.Full Answer >
To set the timer on a Malibu Lighting transformer, users should first turn the dial until the arrow lines up with the correct current time, then set the green tripper at the time they want the lights to turn on and the red tripper to the time they want the lights to turn off. They can then rotate the manual override wheel to turn the lights on if the current time is within the "on" interval of the green and red trippers. The timer does not take into account daylight savings time, so the timer may need to be readjusted twice a year.Full Answer >
UM3 batteries are standard AA batteries, which are produced across multiple battery types. The most common types of AA battery are alkaline, NiMH and lithium. UM3 is the JIS name for AA batteries.Full Answer >
