Solar Contracts vs Utility Bills: What They Don't Compare

The most powerful tool in the solar sales presentation is a simple comparison: your current utility bill versus your proposed solar payment. It's clean, it's compelling, and it leaves out almost everything that matters.

What the Comparison Shows

The standard solar sales comparison shows two numbers: your current monthly utility bill (let's say $200) and your proposed solar payment (let's say $150). The implied conclusion is obvious: you save $50 per month, and over 20 years, that's $12,000 in savings.

This comparison is designed to be persuasive, and it works. The problem is that it's a highly selective presentation of a much more complex financial picture.

What the Comparison Leaves Out

The remaining utility bill. Most solar systems don't eliminate the utility bill — they reduce it. If you still pay $50–100/month to the utility after solar, the comparison needs to include that cost.

The escalator. If your solar payment increases 2.9% per year, it will be $267/month in year 20 — higher than the $200 utility bill you were trying to escape. The comparison almost never shows this.

The total cost. A 20-year loan at $150/month with a 2.9% escalator has a total cost of approximately $48,000 — not $36,000 (which is what $150 × 240 months equals). The escalator significantly increases the total.

The risk factors. Utility service has no performance risk — you pay for what you use. A solar loan has performance risk (what if the system underproduces?), company risk (what if the installer goes bankrupt?), and policy risk (what if net metering changes?).

The Honest Comparison

An honest solar comparison would show the total cost of the solar agreement over its full term (including escalators) versus the projected utility costs over the same period (using realistic rate increase assumptions). It would include the remaining utility bill, the impact on home sale, and the performance risk.

Very few solar sales presentations include this analysis. If yours didn't, you made a decision based on incomplete information — and that matters when evaluating your options.
