Prowse is something of a solar savant. He's a natural teacher and has provided a ton of videos to help you understand the basics of electrical power for small dwellings on his channel. The beginner's video below is one example.
On the website he provides several guides for building solar systems. He calls them solar blueprints. In these guides he goes into the pros and cons of the setup, provides a list of components to purchase, manuals, and detailed schematics and accompanying step-by-step instruction videos for installing the systems.
Beyond his instruction guides, he frequently reviews solar components and solar generators on his channel.
