What has been your favourite museum exhibit ever?
Sunderland central museum has had a stuffed lion (Wallace) on display since I was a bairn (at least) and every time we went to the museum, I would run past the lighthouse lamp ... not even glance at the huge (nine feet in diameter) ship's rope and only pause for a minute or two at the ancient canoe with a skeleton in it so that I could say hello to Wallace ..... only then could I study everything else.
I'm rather fond of the Egyptian mummies at the British Museum, I also like the lapis lazuli jewellery. I've been to so many museums over the years, I can't remember all of them: the dinosaurs at the Natural History Museum; several cabinets with dozens of little drawers inside all lacquered and decorated at ...... was it Hever Castle - one of those stately homes in Kent or Surrey anyway.
I'm interested in the skeleton in the canoe. What was that about?
Electricity can be generated by Solar Photo Voltaic Module
Solar Photo Voltaic Modules are best known as a method for generating electric power by using solar cells to convert energy from the sun into electricity. The Solar Photo Voltaic Module effect refers to photons of light knocking electrons into a higher state of energy to create electricity. The term photovoltaic denotes the unbiased operating mode of a photo-diode in which current through the device is entirely due to the transduced light energy. Virtually all photovoltaic devices are some type of photo-diode.
Solar cells produce direct current electricity from light, which can be used to power equipment or to recharge a battery. The first practical application of photovoltaic was to power orbiting satellites and other spacecraft, but today the majority of photovoltaic modules are used for grid connected power generation. In this case an inverter is required to convert the DC to AC. There is a smaller market for off-grid power for remote dwellings, boats, recreational vehicles, electric cars, roadside emergency telephones, remote sensing, and cathodic protection of pipelines.
Average solar irradiance, watts per square meter. Note that this is for a horizontal surface, whereas solar panels are normally mounted at an angle and receive more energy per unit area. The small black dots show the area of solar panels needed to generate all of the world's energy using 8% efficient photovoltaic.
Cells require protection from the environment and are usually packaged tightly behind a glass sheet. When more power is required than a single cell can deliver, cells are electrically connected together to form photovoltaic modules, or solar panels. A single module is enough to power an emergency telephone, but for a house or a power plant the modules must be arranged in multiples as arrays. Although the selling price of modules is still too high to compete with grid electricity in most places, significant financial incentives in Japan and then Germany, Italy and France triggered a huge growth in demand, followed quickly by production. In 2008, Spain installed 45% of all photovoltaic, but a change in law limiting the feed-in tariff is expected to cause a precipitous drop in the rate of new installations there, from an extra 2500 MW in 2008 to an expected additional 375 MW in 2009.
Perhaps not unexpectedly, a significant market has emerged in off-grid locations for solar-power-charged storage-battery based solutions. These often provide the only electricity available. The first commercial installation of this kind was in 1966 on Ogami Island in Japan to transition Ogami Lighthouse from gas torch to fully self-sufficient electrical power.
World solar photovoltaic (PV) installations were 2.826 gigawatts peak in 2007, and 5.95 gigawatts in 2008, a 110% increase. The three leading countries represent nearly 89% of the total worldwide PV installed capacity. According to Navigate Consulting and Electronic Trend Publications, the estimated PV worldwide installations outlooks of 2012 are 18.8GW and 12.3GW respectively. Notably, the manufacture of solar cells and modules had expanded in coming years.
Germany was the fastest growing major PV market in the world from 2006 to 2007. By 2008, 5.337 GWp of PV was installed, or 35% of the world total. The German PV industry generates over 10,000 jobs in production, distribution and installation. By the end of 2006, nearly 88% of all solar PV installations in the EU were in grid-tied applications in Germany. Photovoltaic power capacity is measured as maximum power output under standardized test conditions. The actual power output at a particular point in time may be less than or greater than this standardized, or "rated," value, depending on geographical location, time of day, weather conditions, and other factors. Solar photovoltaic array capacity factors are typically under 25%, which is lower than many other industrial sources of electricity. Therefore the 2008 installed base peak output would have provided an average output of 3.04. This represented 0.15 percent of global demand at the time.
The EPIA/Greenpeace Advanced Scenario shows that by the year 2030, PV systems could be generating approximately 1,864 GW of electricity around the world. This means that, assuming a serious commitment is made to energy efficiency, enough solar power would be produced globally in twenty-five years’ time to satisfy the electricity needs of almost 14% of the world’s population.
