Why "Cheaper Panels" Doesn't Always Mean a Cheaper System
The real cost drivers
•Inverter choice and warranties
•Racking quality and roof complexity
•Electrical balance-of-system components
•Permitting and interconnection requirements
Where DIY helps
•DIY reduces the "soft costs" that don't improve performance—so you can upgrade what actually matters.
Focus on system value
•A slightly higher-quality inverter or racking choice can prevent years of headaches.
Next step: Build a system, not a shopping cart.
