How rooftop solar can cut your power bills

Installing rooftop solar can significantly cut your power bills, with a typical system paying for itself in about 8 years. For around $10,000, a medium system can meet half of a home's energy needs.

With a lifespan of 25-30 years, panels generate power much cheaper than the grid. Grid-tied systems also allow you to sell excess electricity back to your retailer. A qualified professional must handle the installation to meet current standards and ensure safety.
