Abstract
This project proposes the design and implementation of a hybrid energy generation system that combines wind turbines and photovoltaic (PV) solar arrays to provide reliable and sustainable electricity. Both wind and solar energy are abundant renewable resources, but each has limitations related to weather and time of day. By integrating both systems, we can create a more consistent and efficient power supply. This hybrid system aims to optimize energy generation by harnessing wind power during windy conditions and solar energy during daylight hours, thus reducing dependence on conventional fossil fuels and enhancing energy sustainability.
Introduction
As the global demand for energy continues to rise, renewable energy sources are becoming increasingly important. Wind and solar power are two of the most widely available and environmentally friendly options for energy generation. However, both sources have inherent variability: solar energy is limited to daylight hours, while wind power depends on weather conditions. By combining these two energy sources into a hybrid system, we can ensure a more consistent energy supply, regardless of time or weather, thereby increasing the reliability and efficiency of renewable energy generation.
This project will focus on designing a system that integrates both a wind turbine and a photovoltaic (PV) solar array. The hybrid system will generate electricity from either source depending on availability and store excess energy in batteries for use when generation is low. This setup will not only enhance energy production but also provide a cost-effective and sustainable solution to meeting energy demands in remote or off-grid locations.
Problem Statement
Renewable energy sources such as wind and solar power are subject to fluctuations due to environmental factors, which makes it challenging to rely on a single source of energy for continuous power supply. Solar energy is only available during daylight hours, while wind energy depends on the weather. This variability can result in unreliable energy output, making it difficult to meet consistent energy demands. There is a need for an integrated hybrid energy generation system that combines both wind and solar power to create a more stable and reliable energy supply.
Aim
The aim of this project is to design and implement a hybrid energy generation system that integrates a wind turbine and a PV array to produce continuous, reliable, and sustainable power. The system will optimize the use of both renewable sources and store excess energy for future use.

Literature Review
Wind Energy
Wind energy is one of the fastest-growing renewable energy sources in the world. Wind turbines generate electricity by converting the kinetic energy of wind into mechanical energy, which is then converted into electrical energy using a generator. While wind energy is a clean and renewable source, it is highly dependent on weather patterns and wind speeds, leading to fluctuating energy output.
Solar Energy
Photovoltaic (PV) solar panels convert sunlight directly into electricity through the photovoltaic effect. Solar power is one of the most widely used renewable energy sources globally, with low operational costs and minimal environmental impact. However, solar energy generation is limited to daylight hours, and its efficiency depends on sunlight intensity, weather, and geographic location.
Hybrid Energy Systems
Hybrid energy systems combine multiple renewable energy sources to provide a more consistent and reliable power supply. By integrating wind and solar power, the variability in each energy source can be mitigated, as the system can switch between sources based on availability. These systems often incorporate energy storage solutions, such as batteries, to store excess energy and supply it when generation is low. Hybrid systems are particularly beneficial in remote or off-grid locations where access to a consistent energy supply is critical.
