Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—vertical wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

Wind is a form of solar energy caused by a combination of three concurrent events:

1. The sun unevenly heating the atmosphere

2 .Irregularities of the earth's surface

3. The rotation of the earth. 

Wind flow patterns and speeds vary greatly across the United States and are modified by bodies of water, vegetation, and differences in terrain. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.

The terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

A horizontal wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin. The rotor connects to the generator, either directly (if it’s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to rotation of a generator creates electricity. 

Permanent magnets have been used to provide the magnetic field in small to medium sized generators for many years. The use of these in large renewable energy (RE)generators may offer performance advantages for future utility-scale generators.

  Large (MW sized) permanent magnet generators (PMGs) are mainly found in the wind turbine sector today, but are not confined to this area. PMGs offer a number of advantages to the generator field and are being used in applications from standby plant to hydro generators. The PMG is finding particular application in renewable energy systems, where reduced size and higher efficiency give an advantage. The ability to find application in both low speed and high speed generators is accelerating the use of this type of equipment.

Solar panel connectors are crucial items in the installation of solar generation systems. The connector speeds up the installation and makes it relatively easy by ensuring continuity between cables that connect the modules in the solar array. This allows the current to flow from the solar panel to the solar charge controller, into the solar inverter, and then power every appliance at the home.

The solar cable connector plugged at the end of each wire is the main one responsible for simplifying modular installations for solar systems. By using these connectors, a solar installer can reconfigure the modules when increasing the size of the system, installing modules in parallel or series to achieve the desired array.

Using the right mc4 solar connector is important for the wiring of photovoltaic (PV) modules with other components in the system, especially when using a combiner box for larger systems. In this article, we will dive into the basics of solar connectors, you will learn about the different types of solar connectors, the differences among them, and many other important aspects that you should know.

Photovoltaic wire, also known as PV wire, is a single-conductor wire used to connect the panels of a photovoltaic electric energy system. A solar cable is the interconnection cable used in photovoltaic power generation. Solar cables interconnect solar panels and other electrical components of a photovoltaic system. Solar cables are designed to be ultraviolet resistant and weather resistant.
