The Problem
The Industry Hides the Truth.
These are real homeowner pain points disguised as “financing options” and “estimated savings.” We read the fine print so you don't have to.
The 30% Dealer Fee
+$8,000 hidden
The financed price quietly explodes while the cash quote never appears on page one.
The ‘Estimated’ Production Clause
Zero output guarantee
Installers promise savings with language that protects them if the system underperforms.
The Escalator Rate Trap
+2.9% every year
A low monthly payment turns expensive when the agreement compounds faster than utility inflation.
