Solar Power Inverter
The solar inverter is a critical component in a solar energy system. It performs the conversion of the variable DC output of the Photovoltaic (PV) module(s) into a clean sinusoidal 50- or 60 Hz AC current that is then applied directly to the commercial electrical grid or to a local, off-grid electrical network. Typically, communications capability is included so users can monitor the inverter and report on power and operating conditions, provide firmware updates and control the inverter grid connection. Depending on the grid infrastructure wired …
How do residential wind turbines work?
A wind turbine, which is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home’s electrical system.
In a normal residential application, a home is served simultaneously by the wind turbine and a local utility. If the wind speeds are below cut-in speed there will be no output from the turbine and all of the needed power is …
A wind turbine’s ‘rated’ capacity is its maximum power at an optimum wind speed. This is the value commonly quoted for a wind farm’s ‘installed capacity’. How does this compare with the wind farm’s average power output? That is, what is the capacity factor of wind power?
The capacity factor of a power plant is the ratio of the electrical energy produced in a given period of time to the electrical energy that could …
… in 1996, the wind turbine design was commercialised by African Windpower of Harare and badged the pt3600. Detailed design has been by Scoraig Wind Electric throughout. The wooden blades of the original were replaced by fibreglass, and the tail was simplified.On the left is a 1999 production unit from Powertronics. Tens of machines have been produced for local customers in Zimbabwe and the export market. With the new African Windpower factory, production will be stepped up. A 5.5 m diameter machine is actively under development. Smaller machines around 2 m diameter, will be available …

wind power, form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power. Wind power is considered a renewable energy source. Historically, wind power in the form of windmills has been used for centuries for such tasks as …
During the past, wind power structures has been general ly accepted. The eco-favorable systems, along with the fresh and natural alternative power or energy that it produces, are the reas ons why it ha s been recognized. Some scientists have claimed that wind power is far more desirable compared against solar power, as it can still be utilis ed even after the sun would set.
This type of power is a free power source and it disposes of the use of any material for cre ating energy. But it has its bad side : there ‘s a high price …
Solar power is energy which comes from the sun. This energy is very powerful and hits the earth regardless of whether or not we take advantage of it. Even the tiny percentage of sunlight that touches the earth is plenty to meet the energy and power needs of the entire human population more than 8,500 times over.
The only concern is learning how to collect this energy efficiently. Today there are many different technologies which exist to achieve this goal. Due to concerns of the availability of traditional energy sources, many people today are interested in further developing renewable …

… one hand, in many countries the public in general favours renewable energy sources such as wind power. On the other hand, deploying a wind farm in a local community sometimes raises local resistance due to the neighbours’ uncertainty and negative expectations about the wind turbines. The public concern is often about environmental effects of wind power such as visual intrusion, impact on birds and birds’ habitat, acoustic noise emission, safety, moving shadows, etc. This has been called the NIMBY (Not-In-My-Back-Yard) dilemma.
In industrialised countries public acceptance of wind power is often the most important planning restriction and consequently also a political issue …
FAQ Wind Power
What is wind energy?
Wind energy is the use of the wind as an energy source. A wind energy system transforms the kinetic (moving) energy of the wind into mechanical or electrical energy that can be harnessed for practical use.
Mechanical energy: Wind energy can be harnessed by sails for transportation (sailboats) and other purposes such as grinding grain and pumping water. In the United States, some six million mechanical windmills were in operation in the late 1880s until about 1935, helping homesteaders and farmers to settle the West. …
