Solar Panel Efficiency

Gambar
Technology Articles | August 6, 2010 Over the years solar panels have improved and are now able to generate far more power today than ever before. This is due to better solar cell technology and changes to their overall design that allows them to harvest more sunlight for your home. At the heart of any modern residential solar power system are the PV solar panels. These solar panels are the critical component in the system that does the actual conversion of sunlight to electricity. They do this through the use of solar cells that are designed to take advantage of the photovoltaic (PV) effect. The PV effect occurs in certain materials, that when exposed to direct sunlight will generate a small DC current. In the case of modern solar panels for homes, these solar cells are made from a silicon-based compound that has improved dramatically over the years in efficiency. These modern solar cells are able to provide far more power than older versions and are much more durable as well. In some...

Making Small Turbine Wind Energy At Home

Hobbies Articles | February 26, 2009 Small turbine wind energy is the fastest growing of any renewable energy technology. It is produced in a similar way to how an alternator produces electricity as your car moves. The only difference is the air spins the turbine to produce the power. Small turbine wind energy is the fastest growing of any renewableenergy technology. It is produced in a similar way to how an alternatorproduces electricity as your car moves. The only difference is the airspins the turbine to produce the power. And as the wind speed increasesthe turbine produces more electricity. In windy regions, such as nearcoastlines, small turbine wind energy is an ideal way of producingpower for households and businesses. Even if you do not live in a windy area, small turbine wind energycan still be used to supplement the electricity supply. What's more is,DIY energy guides have lately come about, where motivated people canlearn to make their own small turbine wind energy and re...

Wind Turbine Market 2016 Global Industry Review Research Statistics and Growth to 2021

Marketing Articles | August 4, 2016 Global Market Research Report on Wind Turbine Market 2016 is a professional and in-depth complete study on the current state of the Wind Turbine worldwide. Wind Turbines are devices that help in converting kinetic energy from the wind to electric energy. Many companies are now generating electricity from wind using both offshore and onshore methods. Due to use of fossil fuels, earth’s temperature has risen by 1`C in the last 100 decades. Government is taking initiatives to explore alternative sources of energy due to the lack of natural resources such as fossil fuels. It is a beneficial step for both the planet and the economy to minimize the dependency on limited natural resources such as gas and oil. Wind Turbines could help in achieving balance between supply and demand for electric needs of the century. The capacity to generate electric energy with the help of wind turbines grew tremendously. During 2013, 296’255MW electricity was generated with ...

Lithium ion polymer battery vs NickelCadmium battery A quick comparison

It is certainly much more advantageous over nickel batteries owing to anumber of reasons. One chief difference is that nickel-cadmium battery suffersfrom frequent memory lapses. This problem surfaces when the user recharges hisdevice incessantly over a short duration of time. This problem may also surfacewhen the user overcharges the battery or charges it without fully exhaustingthe initial charge. Since, a modern day user has the habit to put his device onthe power a number of times during the day (owing to increased use of thedevice), this technology certainly proves disadvantageous. Onthe other hand, a china lithium ion battery is free from any sort of memoryproblem. ...

How Does a Wind Turbine Work

Wind generally blows or flows ina forward direction over the surface of the ground. We need to convert thislateral motion into a rotary motion. This is achieved by using angled andtilted blades that work in the same way as the sails o...

Lithium Ion Batteries Supercharging The Tool Industry

Gambar
Technology Articles | April 16, 2020 Lithium Ion (Li-Ion) battery technology is one of the fastest growing trends in the tool community, and certainly for good reason. This article seeks to inform about this revolution in the battery industry and to understand its strengths and weaknesses.� Lithium Ion (Li-Ion) battery technology is one of the fastest growing trends in the tool community, and certainly for good reason. Lithium Ion batteries have the best energy to weight ratio, meaning they pack the most power with the smallest amount of bulk. They also experience no memory effect or, lazy battery effect. This occurs when a battery can no longer accept a maximum charge for having been repeatedly recharged without being fully used (a common symptom of Nickel Cadmium (NiCad) batteries). Li-Ion batteries, conversely, have absolutely no memory and can continually accept a maximum charge. Additionally, they have a very slow rate of charge loss while the battery is disengaged. What is the di...

Build a Wind Turbine to Save the Earth

Home Repair Articles | November 22, 2011 Okay, so building a wind turbine won�t necessarily �save� the earth, butit will help to reduce emissions and pollution from power plants andthis does help the environment, especially if more people do it. Notonly would you save money on your electric bill or totally eliminate itwhen you build a wind turbine, but you will also be helping theenvironment and inspire your neighbors to do the same.� What Does a Wind Turbine Do? A wind turbine is basically a tower with three blades at the top that rotate when wind flow strikes them. The faster the wind, the greater the amount or power wattage produced. This is because these rotating blades are attached to a magnetic generator, which generates electricity. When you build a wind turbine, this electricity is delivered to your home and can be used as an electrical power source instead of using the local power grid. The end result is a reduced utility bill or elimination of the cost of electricity altogeth...

Nanometer silicon powder can increase capacity and anti attenuation of battery

Gambar
Business Articles | June 11, 2012 Because of high absorption rate of nanometer silica fume and lithium battery, nanometer silica fume can significantly improve capacity of lithium battery. Nanometer silica fume and graphite can become alternatives of nano toner as raw materials. �It is a lithium battery anode material. Silicon / graphite composite materials are prepared by mechanical milling method and the corresponding complexes are tested by charge-discharge. It is found that the best ratio of silicon and graphite is 1:9. Si-C composite materials can effectively reduce the expansion of lithium-ion absorption by silicon powder. It can increase the affinity with the electrolyte at the same time. It can improve cycling performance. Nanometer silica fume made of silicon nanowires used in rechargeable lithium ion battery anode material, or coated graphite surface of the nanometer silica fume do rechargeable lithium ion battery anode material can be improved more than three times the elect...
