How Do Solar Panels Work? (Science in the Real World) by Richard Hantula

By Richard Hantula

Solar is a unfastened, limitless source that hits the Earth with extra strength in an hour than the folk of the area use in a yr. This name unearths how researchers are engaged on how one can harness the ability of solar via sun panels and delves into the technology in the back of those panels.

Das Thema soll in einen Grenzbereich der Materialwirtschaft führen, der durch die tagespolitischen Ereignisse immer größere Bedeutung für die Unternehmung gewinnt. Naturgemäß ist in einer marktorientierten Gesellschaft das verkaufs­ fähige Produkt da~ Objekt aller Anstrengungen und Leistungen. Produktion und Verkauf stehen im Blickpunkt, andere Bereiche werden als notwendig be­ trachtet, während das Gebiet der Entsorgung innerhalb der Unternehmung zu­ nächst ohne besondere Beachtung bleibt.

Example text

Many people think devices called hydrogen fuel cells might someday be very good sources of power for many purposes. They use hydrogen to make electricity. Hydrogen is very common. It is in water, for instance. Getting the hydrogen out of water, however, takes energy. If solar panels get cheap enough and efficient enough, they might become a practical way of providing this energy. Ways of getting lots of sunlight to solar cells are being studied. One proposed concentrator could be used on windows.

The dyes let some light through the window. They also capture some light energy, which flows to the cells. DID YOU KNOW ? Power from Space In space there are no clouds. Solar panels there can get lots of sunshine. Scientists have proposed using huge solar arrays on satellites to make power. The power would then be beamed down to Earth for use. A big question is whether long-distance beams are practical. An experiment in 2008 managed to send a small amount of energy about 90 miles (150 kilometers).
