Solar_wind hybrid system
1.introduction
Hybrid renewable energy systems are becoming popular as stand-alone power systems for
providing electricity due to advances in renewable energy technologies and
subsequent rise in prices of petroleum products. A hybrid energy system, or hybrid power,
usually consists of two or more renewable energy sources used together to provide
increased
system efficiency as well as greater balance in energy supply.[1]
2.Solar_wind hybrid system
It's The combination of wind and solar.it has the
advantage that the two sources complement each other because the peak operating times
for
each system occur at different times of the day and year. [2]
Solar_wind hybrid system create more output from the wind turbine during the winter,
whereas
during the summer, the solar panels would produce their peak output[3]
The sun is available in the day , whereas wind energy is available throughout the
day and its capacity increases in the nights. Here when sun is not
available wind energy comes to play and vice-versa.

5.How Solar_wind hybrid system work
1-solar panels collects light and convert it to energy.
2-wind turbine collects energy from the wind.
3-collector used to charge batteries.
4-inverter used to convert Dc to Ac power.[4]
6. Advantages and disadvantages
Advantages
1. Continuous power supply .
2. Very high reliability (combines wind power, and solar power).
3. Low maintenance cost.
4. Efficient , easy installation and longer life.
5. No pollution, Clean and pure energy.
Disadvantages
1. Complicated controlling process
2. High installation cost .
3. Less battery life.
4. Efficiency is less than conventional power plants.
7. DESIGN OF HYBRID ENERGY SYSTEM
For design of the hybrid energy system we need to find the data as
follows:
DATA REQUIRED FOR SOLAR SYSTEM
1. Annual mean daily duration of Sunshine hours .
2 .Daily Solar Radiation horizental(KWh/m2/day).
DATA REQUIRED FOR WIND SYSTEM:
Mean Annual Hourly Wind Speed (m/sec) .
