Solar Wind hybrid
With Wind Solar hybrid system, you can benefit from both forms of energy sources which happens to give way to each other in different seasons of the year. But, for the hybrid system to work, at least 60% of the power must come from ‘wind’ and the wind speed should be at least 15 kmph on an average. The hybrid system generates as much as 5 units of power every day.
Many hybrid systems are stand-alone systems, which operate "off-grid" -- not connected to an electricity distribution system. For the times when neither the wind nor the solar system is producing, most hybrid systems provide power through batteries and/or an engine generator powered by conventional fuels, such as diesel.
A microgrid is a small-scale power grid that can operate independently or collaboratively with other small power grids. The practice of using microgrids is known as distributed, dispersed, decentralized, district or embedded energy production. Any small-scale, localized power station that has its own generation and storage resources and definable boundaries can be considered a microgrid. If the microgrid can be integrated with the area's main power grid, it is often referred to as a hybrid microgrid.
Microgrids are typically supported by generators or renewable wind and solar energy resources and are often used to provide backup power or supplement the main power grid during periods of heavy demand. A microgrid strategy that integrates local wind or solar resources can provide redundancy for essential services and make the main grid less susceptible to localized disaster.
