Solar Panels: A Technical Primer

As the Earth turns lower on natural resources and traditional forms of energy, we have little humans must trust our creativity and technical ingenuity to keep our buzz civilization. We hope that the future will see all kinds of wild progress in the way we produce, use and save energy. Meanwhile, today already has a lot of gadgets that put us on track to own high-power world.

Solar panels are one of the most simple and easy to implement alternative energies that have to date technologies. They use simple principles of energy transfer to bring electricity to your home without causing harmful side effects to the environment.

Most of us have seen the futuristic solar panels located above the roofs of houses or industrial sites. How exactly? Furthermore, each installation is a series of modules arranged in the ceiling in a manner that exposes them to sunlight daily. When the sun shines, sends rays of light called “photons” hurtling towards the ground. These photons contain energy. This is the same energy that plants absorb and convert organic matter then used for food.

Solar panels are similar because they convert the inherent energy in photons into something useful. They make use of what is called the photovoltaic effect, or physical phenomenon observed in which the photons hitting a material surface and excite the particles in the material. Each module is covered by a thin film silicon based and cadmium. When the sun hits them, excites electrons of atoms of silicon and cadmium – in other words, it gives them a boost and makes them move. Now, Physics 101 tells us that when a particle is in motion, has energy. Therefore, the PV cycle is complete. Photons have done all the work by transferring energy to the billions of electrons in their modules.

How this energy is available for electric lights, televisions and other electronics? Each module is connected by a series of electrical conductors. The specific provision of child directs the flow of excited particles in your home power system, delivering power when you need.

How cool is that? The energy is never created or lost – it just moved, processed and used for human consumption.

The first solar panels are used in space by the end of 1950 Now the technology behind them gives owners the ability to monitor and control the amount of energy absorbed from the sky. Systems now come with computer programs that accurately measure the amount to be current produced in each module. They allow users to experience weak or problematic modules and see the exact amount of energy produced daily, monthly, and time is running every year.

Solar panels are really amazing and necessary innovation. They represent the best of our ability to manipulate the rules of the natural world to help us without doing any damage.

 


My favourite Books on Web Design

Don't let the 3 star rating keep you from buying this book. I liked it, and if you are in the audience this book is written for, you will likely find it to be quite useful. On a price / value basis, it's a good deal.

The benefit of the book is that it provides introductory material, presented in a consistent manner, in one place. I read it on a train, while commuting and it solidified several concepts that were not previously clear after reading disjointed blog posts for a few evenings. The author writes in a clear, friendly manner, and while I generally like a more concise and to-the-point style, he's not over the top with unnecessary verbiage.

This self-published book comes in at about 60 pages. The author maintains the sample code on GitHub .I would have like to seen an approach where the author took several HTML web pages and created a theme from scratch using the pages as a starting point. I think a lot of readers will be in a situation.where they want to start using WordPress for their CMS as well as for managing blog posts, and working through an example of porting a site from plain HTML to WordPress by creating a custom theme would have been a better teaching technique.

But, all-in-all, a good read. If Joe were to write another 60 page book on this topic but for a more advanced audience, I would consider buying it.

CSS Mastery: Advanced Web Standards Solutions (Black & White)

Building on what made the first edition a bestseller, CSS Mastery: Advanced Web Standards Solutions, Second Edition unites the disparate information on CSS-based design spread throughout the internet into one definitive, modern guide. Revised to cover CSS3, the book can be read from front to back, with each chapter building on the previous one. However, it can also be used as a reference book, dipping into each chapter or technique to help solve specific problems. In short, this is the one book on CSS that you need to have.

 

This second edition contains:

  • New examples and updated browser support information
  • New case studies from Simon Collison and Cameron Moll
  • CSS3 examples, showing new CSS3 features, and CSS3 equivalents to tried and tested CSS2 techniques

Who this book is for

This book is aimed towards intermediate web designers/developers, although the examples are simple enough for novice designers/developers with a basic understanding of CSS to grasp.

The CSS 2/3 content of the book is delivered in a way that enables you to learn CSS2 techniques that you can implement now in professional work, and then gem up on CSS3 techniques to start looking towards the future.

 

 

What you’ll learn

  • The best practice concepts in CSS design.
  • The most important (and tricky) parts of CSS
  • Identify and fix the most common CSS problems
  • How to deal with the most common bugs
  • Completely up to date browser support information
  • Covers CSS3 as well as CSS2 showing you the future of CSS
