This document describes a hybrid energy system that combines solar, wind, and fuel cell technologies. The system aims to provide reliable power for a 1kW load. It uses 6 photovoltaic panels that generate 1.5kW of power during the day. A vertical axis wind turbine produces 1.2kWp of power. A proton exchange membrane fuel cell stacks adds 1kW of power. The hybrid system mitigates the intermittency of solar and wind energy by allowing excess power generated to charge the fuel cell for use when renewable sources are unavailable. The document outlines the component selection and system design, and discusses innovations that could improve the efficiency and viability of such hybrid energy systems in the future.

2. INTRODUCTION:
WHAT IS A HYBRID SYSTEM?
 Integration of two or more renewable energy
source (In this case) to form a more reliable system
is called a hybrid system
WHY SHOULD WE USE A HYBRID SYSTEM?
 One drawback with renewable energy sources is
their variability
 To mitigate this problem we use a hybrid system

3. WHEN WILL IT BE EFFECTIVE?
 Solar energy will contribute the daytime running of
the load and charging of storage device during day.
 Wind will contribute its energy during its flow time to
the load.

4. WHICH IS THE BEST HYBRID AT THIS MOMENT?
 Solar energy is the only source of energy that is
available almost everyday.
 Wind is the second most abundant source.
 Hence a solar-wind hybrid system would be the most
effective system

5. WHERE WILL IT BE
EFFECTIVE?
 The place of installation
must have abundant solar
insolation.
 The place must have high
wind flow rate which must
be fairly predictable.

6. HOW CAN YOU STORE THE ENERGY?
 Traditionally batteries are used for storage.
 Recent innovations in this field led to the highly
efficient fuel cell technology.

8. OVERVIEW
 The objective of this project is to integrate these
efficient systems into a single hybrid system for a
better energy generation and storage for a 1kW
load.
 The power generated from wind is the primary
contributor with 1kW. In case of deficit, power from
PV module is used for compensating the additional
requirement.

9. FUEL CELL TECHNOLOGY
