hybrid system refer to a home wind or solar power system that can be connected to a national grid system, hybrid system is many advantages over signal power generation because it combine wind, electrical, solar and photovoltaic technologies in a single one.
in many area when the wind pressure is greater in one season and solar is less, or solar is greater and wind is less, etc hybrid system is the best option for these areas, for the time when neither the wind neither the solar system are , most hybrid system provide power through batteries or engine generator using fuels such us diesel etc, if batteries low then generator provide the power.
many system are stand alone system which operate off grade, i.e not connected to any system, to store the power which is produces its advisable to purchase batteries, and a charge controller.power condition equipment , safety equipment , metering and instrumentation.
