Complete Solar Kits vs DIY: What Is Included (and What Is Not)
AGAIC complete kits include panels, inverter, mounting hardware, cables, and monitoring — everything except installation labor. The advantage: components are pre-tested for compatibility, wiring diagrams are included, and you get a single warranty point of contact.
DIY sourcing might save 10–20% on components but costs time, risks compatibility issues, and leaves you managing multiple warranties. For most homeowners, a complete kit saves 10–20 hours of research and eliminates the "will this inverter work with these panels?" headache.
