Solar photovoltaic technology, which converts sunlight directly into electricity, has fallen in cost so far that it is now the most inexpensive method of getting electricity, period. If you have any money in the bank and own your home or business, consider investing in solar power for yourself now, as you can do some good for the planet and your wallet simultaneously.

But can you still take advantage of solar if you live in an apartment or aren’t flush with cash?

Yes, thanks to open source tech development, you absolutely can. If you are a little handy, you can cut the costs of solar power even further by building your own systems of any size and budget, and To Catch the Sun guides you on exactly how to do it. To Catch the Sun is a brand new book I co-authored with the legendary open source appropriate technology hacker and Appropedia founder Lonny Grafman. Built on open source MediaWiki and Semantic MediaWiki, Appropedia is the largest wiki dedicated to developing and sharing collaborative solutions in sustainability, poverty reduction, and international development through the use of sound principles and appropriate technology. Together we are something like the double-O 7 team of the solar world. A bit like James Bond, Lonny Grafman from sunny California, is an adventurer taking his students from Humboldt State University all over the world to build solar photovoltaic systems in the most challenging conditions. I am perhaps more Q-like, developing open source solar photovoltaic technology quietly from my labs deep in the north at Western University in Canada. Together we provide ways to make solar work for you in just about any context.

Working with electricity is exciting for some of us, but to ensure everyone can come along for the ride, we provide lots of interesting and sometimes funny stories of people from all over the world meeting their energy needs with small solar systems.

Better yet, and in keeping with the spirit of the text, it is a free open access e-book.

While you are reading inspiring stories of communities coming together to harness their own solar energy, you will learn how to design and build a photovoltaic system for:

  • A small home in a financially rich country
  • A few homes in financially developing countries
  • School rooms and community spaces
  • Zombie-apocalypse equipment
  • Laptop and cellphone chargers
  • A tiny home or van life
  • Glamping and backpacking equipment
  • Emergency supply, e.g., powering an oxygen machine during a power outage
  • Isolated loads like electric gates, pumps, greenhouse fans, backup generators, telecommunications equipment, and much more

Beginners can walk through the steps to build state-of-the-art solar energy systems to meet their own needs using open source plans and transparent calculations. This book is for anyone looking to develop solar projects and knowledge:

  • Students and teachers in the science, math, engineering, environmental, social justice, and technical fields, especially at high school and undergraduate university levels
  • Community organizers and builders looking to build solar projects
  • Entrepreneurs and inventors looking to build solar products
  • Families looking to learn together
