Announcing the Second Edition of Off Grid Solar Book


I am delighted to announce that the second edition of my book Off Grid Solar is available now on Ingram Book Group. It is available and distributed to 39,000+ retailers (including Barnes & Noble and your local independent bookstore), libraries, schools, and universities.

The first edition was published at the end of 2016. In the past three years I have been working with more battery systems and building more complex energy storage systems. I have more in-depth knowledge solar and battery projects now and this knowledge was transferred into this next edition.
