The goal of the first edition of this textbook was to present a comprehensive
engineering basis for photovoltaic (PV) system design, so the engineer would
understand the what, the why and the how associated with electrical, mechanical,
economic and aesthetic aspects of PV system design. The first edition was intended
to educate the engineer in the design of PV systems so that when engineering
judgment was needed, the engineer would be able to make intelligent
decisions based upon a clear understanding of the parameters involved.
Life on Earth is dependent on sunlight. In the process known as photosynthesis, plants,
algae and certain bacterias are capable of using this source of energy to drive the synthesis
of organic compounds. The oxygenic photosynthesis results in the release of molecular
oxygen and the removal of carbon dioxide from the atmosphere that is used to synthesize
Ozone (O3) is a secondary pollutant formed in the atmosphere throughout a complex non-linear chemical reaction involving two classes of precursors: the reactive volatile organic compounds (VOCs) and the oxides of nitrogen (NOx) in the presence of sunlight. The rapid urbanization and industrialization in Vietnam have brought about high air pollutant emissions including the O3 precursors. Ground level O3 may already be high in large cities like Hanoi and Ho Chi Minh City. The O3 episode is very important for scene of view of photochemical smog in Hanoi.
