How Solar Energy Becomes Electricity

canada goose coats With so much sunlight reaching our planet every day, it seems incredible how mankind has not yet found a truly Canada Goose Outlet efficient way to harness all the free solar energy and use it for every day’s needs. canada goose coats

Canada Goose Parka A lot of progress has been made in the last 60 years, and researchers are finding more efficient and cost effective ways to produce electricity from solar energy, but much still needs to be done before it can be used by canada goose black friday sale every family. Canada Goose Parka

canada goose uk shop It is every ecologist’s dream that one day we will completely abandon carbon fuels and nuclear plants, that produce extremely hazardous and contaminating waste, and switch completely to renewable energy sources. canada goose uk shop

Canada Goose sale Technical details of a solar power systemA single PV cell is a thin semiconductor sandwich, with a layer of highly purified silicon. The cheap Canada Goose silicon sandwich presents surplus of electrons on one side and a deficit of electrons on the other side. Canada Goose sale

cheap canada goose uk When the sandwich is stricken buy canada goose jacket cheap by sunlight, photons from the sunlight knock loose some of the excess electrons that tend to migrate to the deficit side. This creates a voltage difference that in each silicon cell is only 0.5 volt. cheap canada goose uk

canada goose factory sale Metallic contacts are made on both sides of the wafer. When an external circuit is attached, the electrons prefer to take the long way around trough the metal, rather than struggle through the silicon, generating a complete circuit and current flow. The PV cells act as a pump for electrons, with no storage Canada Goose sale capacity. canada goose factory sale

cheap Canada Goose The amount of current is determined by the number of electrons that the solar photons knock off. Solar energy is a «clean» energy resource: it canada goose does not involve the emission of greenhouse gases. cheap Canada Goose

canadian goose jacket Solar energy is a renewable and inexhaustible resource. canadian goose jacket

buy canada goose jacket Because PV systems don’t rely on exposed wires, residential PV systems are more reliable than utilities, especially in severe weather. buy canada goose jacket

uk canada goose PV modules have no moving parts, so there is no deterioration due to movements. uk canada goose

PV systems are a great way to power units canada goose clearance sale in remote locations, from homes in isolated areas, to satellites.

canada goose uk black friday Efficiency of solar panelsPV modules do not convert 100% of the solar energy canada goose coats that strikes them into electricity. The average is about 12 14% of conversion efficiency. Conversion rates of over 20% buy canada goose jacket have been achieved in laboratories by using experimental cells made with esoteric and rare elements, but those are too expensive to be commercialized. canada goose uk black friday

canada goose clearance The first PV systems were very expensive, and had an efficiency of about 6%. The cost of PV has come down enormously, and now they are quite affordable. Today’s single crystal silicon modules have shown an increased efficiency of 17 19%, while multi junction photovoltaic cells hold the current record exceeding 40%, according to National Renewable Energy Laboratory (NREL). canada goose clearance

canada goose store Modules installed under average US conditions reach energy payback in three to four years. Quicker energy paybacks are expected in the future, as more «solar grade» silicon becomes available. canada goose store

buy canada goose jacket cheap Net MeteringNet metering is a special agreement between utilities and their customers that allows small renewable energy systems to connect to the power grid. buy canada goose jacket cheap

canada goose clearance sale When a net metering customer produces more energy than what is needed, the electric meter runs backward generating credits. canada goose clearance sale

uk canada goose outlet Net metering customers are charged only for the «net» power that they consume from the electricity service provider or, if their energy generating systems make more electricity than is consumed canada goose outlet , they may be credited or paid for the excess electricity contributed to the grid. uk canada goose outlet
