-There are many [[electrical:solar:sizing#calculators|calculators where you can plug in the numbers]].  This page is a 35,000ft view of how choices affect what you will need.
+This article focuses on designing a DIY power system from scratch.   See [[opinion:solar:sizing.walkthrough|this article]] for a sample walkthrough of how it might be applied for a given use case.
