A Common Misconception

Most people think solar panels are a simple purchase: you buy them, they make electricity, you save money. What nobody tells you is that the solar industry is built on optimistic math — blended paybacks, hidden costs, and assumptions more optimistic than historical data supports.

Here's the thing that makes everything click: a solar panel only saves you money when you use its electricity while it's being made. Every kilowatt-hour you can't use gets exported to the grid — and the grid pays you a fraction of what it costs you to buy electricity. More panels doesn't mean more savings. It means more expensive overflow.

The core idea: The best solar system isn't the biggest one that fits on your roof. It's the right-sized one where almost everything you generate gets used in your home. Everything else is a sign you paid for capacity you didn't need.
