Why Your Solar Deal Was Structured Against You

The solar deal that looked so compelling at the kitchen table was likely built using a set of financial assumptions and structures that were designed to make it look better than it actually is. Understanding those mechanics is the first step toward evaluating your situation honestly.

The Monthly Payment Comparison Trick

The most common sales technique in solar is the monthly payment comparison: "Your utility bill is $200/month. Your solar payment will be $150/month. You save $50 every month." This comparison is almost always misleading for several reasons.

First, the utility bill comparison uses your current rate, but the solar payment often has an escalator that will increase it every year. Second, the comparison ignores the fact that you may still have a utility bill after solar. Third, it focuses on the first-year payment without showing the 20-year total cost picture.

A truly honest comparison would show the total cost of the solar agreement over its full term versus the projected utility costs over the same period. That comparison is almost never shown in the sales process.

Hidden Dealer Fees

Many solar loans include a "dealer fee" — a markup that the financing company charges the installer, which is then rolled into the homeowner's loan balance. These fees typically range from 20–40% of the system cost.

What this means in practice: if your system cost $30,000 and the dealer fee is 30%, your actual loan balance may be $39,000 or more. You're paying interest on $9,000 that went to the financing company, not to your solar system. This dramatically increases the true cost of the deal.

Production Estimates as a Sales Tool

Solar production estimates are generated by software that can be adjusted. Shading assumptions, panel efficiency ratings, degradation rates, and weather data can all be manipulated to produce a more favorable projection. When the estimate is used to calculate savings, an inflated estimate produces inflated savings numbers.

The homeowner has no way to verify these estimates at the time of signing. They're trusting that the numbers are honest. When they're not, the homeowner discovers the gap only after the system is installed and the bills start coming in.
