Off Grid Solar Book is a pocket guide and quick-reference book on off-grid solar systems. Its core focus is how to build an independent power system using solar technology while completely disconnected from the electrical grid. The website clearly states that the book covers “Photovoltaics with Lead-Acid or Lithium-Ion batteries,” meaning photovoltaic systems involving lead-acid and lithium-ion batteries. It is available in English and Spanish and can be purchased on Amazon.com and through local bookstores.
As an educational product, this is not a live course, recorded course, or 1-on-1 training program, but a practical handbook for people who want to build and understand systems. Its target readers include makers seeking energy independence, builders interested in solar-powered setups, and anyone who wants to learn how off-grid systems are put together. The website also offers a blog, technical resources, Solar Tools, an FAQ, and a consulting contact point for further reading, but it does not show a full table of contents, lesson schedule, hands-on projects, or structured learning path.
The author, Joe O'Connor, is presented as a solar entrepreneur, product designer, consultant, speaker, and author. He has installed solar systems in the United States, Haiti, Guatemala, Portugal, and the Democratic Republic of the Congo. His OCON Energy Consulting has more than 10 years of product design and engineering experience related to solar energy and manufacturing engineering. From a professional background perspective, the book has a strong engineering-practice orientation and is well suited to readers who want to start from the standpoint of building real systems.
The website does not disclose a specific price; it only says the book can be purchased on Amazon.com and at local bookstores. Subscribing to the newsletter provides access to a free excerpt. There is no mention of certification, completion certificates, assignment grading, community Q&A, or structured learning support. As a result, its value mainly comes from the content itself rather than course services or career credentials.
The main strengths are its clear positioning and focus on off-grid photovoltaics rather than a broad, general discussion of renewable energy. The author’s hands-on experience and engineering consulting background also add to its practical value. The limitations are that it is not very course-like, and the available information is incomplete regarding how systematic it is for beginners, whether it includes diagrams and case studies, and how frequently it is updated. It is better suited to self-directed learners who are preparing small off-grid power projects or need a project reference. If your goal is to earn a certificate, receive structured training, or study in Chinese, alternatives such as Coursera, edX, Udemy, or domestic photovoltaic training programs may be more appropriate.
The main text does not explain access from mainland China, Amazon purchasing, payment methods, or ebook availability, so the actual experience may be uncertain. If accessing or buying through Amazon is inconvenient, readers can consider local book channels, ebook platforms, or supplementing with Chinese photovoltaic textbooks and industry training.
