This book provides a broad overview on the different aspects of solar energy, with a focus on photovoltaics, which is the technology that allows light energy to be converted into electric energy.Renewable energy sources have become increasingly popular in recent years, and solar is one of the most adaptable and attractive types – from solar farms to support the National Grid to roof panels/tiles used for solar thermal heating systems, and small solar garden lights....

The book "The Truth About Solar Panels:The Book That Solar Manufacturers, Vendors, Installers And DIY Scammers Don't Want You To Read" comes as an answer to all the misleading and poor quality information about solar panels, currently available on the web, provided by “experts” of questionable skill and experience.This book has been written by authors holding master’s degree in electrical engineering, who have a huge experience in design and operation of electrical...

"Electricity is a form of energy. Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons.Before electricity generation began slightly over 100 years ago, houses were lit with kerosene lamps, food was cooled in iceboxes, and rooms were w...

Benjamin Franklin recognized the attraction between objects given excess charge and objects made deficient in charge. Particle physicists attribute force of attraction to photons having particle and wave properties as do electrons. This force can produce damaging electric breakdown over a scale ranging from the atmosphere to electronic circuits and can produce light for illumination or display.

Energy efficiency is today a crucial topic in the built environment - for both designers and managers of buildings. This increased interest is driven by a combination of new regulations and directives within the EU and worldwide to combat global warming.All buildings now must now acquire and display an EPC (energy performance certificate), a rating similar to the A–G rating given to white goods. But in order to understand how to be more efficient in energy use, you need first to un...

One of the most important subjects for any student of engineering to master is the behaviour of materials and structures under load. The way in which they react to applied forces, the deflections resulting and the stresses and strains set up in the bodies concerned are all vital considerations when designing a mechanical component such that it will not fail under predicted load during its service lifetime.All the essential elements of a treatment of these topics are contained within this c...
