| Summary: | Renewable energy has been a research area of exponentially increasing interest since the past
decade along with the more attention that people pay to environment and energy problems.
The growing demand for clean sources of energy has expanded dramatically in recent years
as conventional energy like oil becomes scarce and more expensive. Because of this growth,
it has led to demand for searching alternative source energy. Therefore, the aim of this project
is to build a solar energy system in an isolated home.
This project focuses on two parts. It started on design and development of the inverter
system. The inverter system consists a basic DC-DC boost converter topology to boost the
DC voltage from the charge controller to a higher voltage level for the DC-AC inverter and
the single-phase full bridge inverter to converter the DC voltage to an AC voltage of 230Vac
at 50Hz.
The second parts followed by studying the photovoltaic (PV) module to find its
characteristics and maximum power point (MPP) under various solar radiations. Controller
circuitry to track the maximum power point was introduced.
Simulations were carried out using PSIM software for verification before hardware circuits
were developed for actual implementation. |
