I have developed a board game, and the purpose of it is to display how to design solar electrical systems on a variety of hypothetical sites, estimating the size of the system, selecting the components, and evaluating the annual production of that system.  You can check your answers to ensure that your calculations are correct.

After establishing that your methods of calculation are accurate (and by familiarizing yourself with all the parts of a system), you should be able to accurately assess your home for its own solar electrical system.  That is the purpose and meaning behind the board game.
