Wind Turbine Components - wind turbine parts
Wind turbine usually has six main components: the rotor, the gearbox, the generator, the control and protection system, the tower and the foundation.
Rotor - The rotor is an elegant aerofoil shaped blades which take the wind and aerodynamically converts its kinetic energy into mechanical energy through a connected shaft.
Gearbox - The gearbox alters the rotational velocity of the shaft to suit the generator.
Generator - The generator is a device that produces electricity when mechanical work is given to the system.
Control and Protection System - The protection system is like a safety feature that makes sure that the turbine will not be working under dangerous condition. This includes a brake system triggered by the signal of higher wind speeds to stop the rotor from movement under excessive wind gusts.
Tower - The tower is the main shaft that connects the rotor to the foundation. It also raises the rotor high in the air where we can find stronger winds. With horizontal axis wind turbines, the tower houses the stairs to allow for maintenance and inspection.
Foundation - The foundation or the base supports the entire wind turbine and make sure that it is well fixed onto the ground or the roof for small household wind turbines. This is usually consists of a solid concrete assembly around the tower to maintain its structural integrity.

Farming Principle: Deep Soil Preparation
Looking at GB as a three-legged stool, deep soil preparation is one of the legs. Deep soil preparation builds soil and soil structure by loosening the soil to a depth of 24 inches (60 cm). Ideal soil structure has both pore space for air and water to move freely and soil particles that hold together nicely.
Smart Home Ecosystem - Smart Home Automation - Smart Home Security - Smart Home Technology
The outer-most level corresponds to the individual devices and sensors that consumers interact with. Several candidates are vying for the role of a leader introducing smart home services to the mass market.
Solar Energy Systems - Solar Modules - Solar Electric System Design - Solar Power
The heart of a photovoltaic system is the solar module. Many photovoltaic cells are wired together by the manufacturer to produce a solar module. When installed at a site, solar modules are wired together in series to form strings. Strings of modules are connected in parallel to form an array.
Solar Energy Systems - Array Mounting Racks - Solar Ray - Solar Panel - PV Racks and Mounts
Arrays are most commonly mounted on roofs or on steel poles set in concrete. In certain applications, they may be mounted at ground level or on building walls. Solar modules can also be mounted to serve as part or all of a shade structure such as a patio cover. On roof-mounted systems, the PV array is typically mounted on fixed racks, parallel to t
Solar Energy Systems - Grounding Equipment
Grounding equipment provides a well-defined, low-resistance path from your system to the ground to protect your system from current surges from lightning strikes or equipment malfunctions. Grounding also stabilizes voltages and provides a common reference point. The grounding harness is usually located on the roof.
Solar Energy Systems - Solar Inverter - Solar Panel Inverter
Most grid-connected inverters can be installed outdoors, while most off-grid inverters are not weatherproof. There are essentially two types of grid-interactive inverters: those designed for use with batteries and those designed for a system without batteries.
Solar Energy Systems - Solar Disconnects
Automatic and manual safety disconnects protect the wiring and components from power surges and other equipment malfunctions. They also ensure the system can be safely shut down and system components can be removed for maintenance and repair.
Solar Energy Systems - Solar Battery Bank
Batteries store direct current electrical energy for later use. This energy storage comes at a cost, however, since batteries reduce the efficiency and output of the PV system, typically by about 10 percent for lead-acid batteries. Batteries also increase the complexity and cost of the system.
Solar Energy Systems - Solar Charge Controller
A charge controller, sometimes referred to as a photovoltaic controller or battery charger, is only necessary in systems with battery back-up. The primary function of a charge controller is to prevent overcharging of the batteries. Most also include a lowvoltage disconnect that prevents over-discharging batteries. In addition, charge controllers pr
Solar Energy Systems - The NEC and PV Systems
Solar PV systems must be installed in accordance with Article 690 of the National Electric Code, which specifically deals with PV systems, as well as several other articles of the NEC that pertain to electrical systems in general. When there is a conflict between NEC 690 and any other article, NEC 690 takes precedence due to the unique nature of PV
