Off Grid Solar is a pocket guide and quick reference for anyone looking to build an electrical energy system with the free sunshine available to us all.

“The limitations to widespread solar are not centered on the cost, the efficiency, or the need for advancements in technology. The limitations are solely due to the lack of widespread knowledge on the subject.”

With that philosophy at heart, solar and battery expert Joseph P. O’Connor draws from his years of experience to craft a how-to guide needed by everyone around the world. Founder of OCON Energy Consulting, O’Connor has conducted and taught the installation/maintenance of Off Grid solar projects to people and communities as far away as the central African rainforest and right in his own backyard of Oakland, California. For anyone interested in harvesting their own solar energy completely detached from the grid, this is the book for you.

Thanks to straightforward explanations for readers of all levels, this book establishes a familiarity with the basic low cost components alongside the most innovative technologies. With this knowledge the reader can make better decisions based on their technology needs, rather than simply trusting the recommendations from others.

Need to keep costs down? How many solar panels are needed to refill the batteries? What is the best way to angle your solar panels? On projects both big and small, Joe’s got you covered.

    Good, but keep it real about batteries, please This is a great primer with a wealth of information, but there is far too much concentration on Lithium-Ion batteries, which might be great for those that can afford them, but for most readers, will be in a fantasy realm in the present moment. The SOC figures for all lead-acid batteries (Flooded, gel, and AGM) are lumped together, which is misleading, and may cause users with AGM batteries to ruin their batteries by letting their SOC dip below 12.7 V. In the real world, folks normally choose…

    A practical guide for understanding and installing Off Grid Solar systems. Off Grid Solar is a great starter book for anyone who wants a better understanding of solar energy in general and the potential of “off grid” solar systems specifically. It can also be used as a guide on how to install both the solar panels needed to capture sunlight and the batteries required to store and disperse the retained energy.Joe O’Connor used good analogies to simplify what might otherwise be complex topics to the handyman while providing the science and instructions…
