Going solar is one of the best financial decisions a homeowner can make in 2026. With the 30% federal tax credit, falling panel prices, and rising electricity rates, most systems pay for themselves in 7-12 years and save $25,000-$50,000 over their 25-year lifespan.
How Solar Panels Work
Solar panels convert sunlight into DC electricity using photovoltaic cells. An inverter converts this to AC electricity for your home. Excess power goes to the grid (earning credits via net metering) or charges a battery. A typical 7 kW system has 18-22 panels and covers 85% of the average home electricity needs.
How Much Does Solar Cost?
The average residential solar installation costs $15,000-$30,000 before incentives, or $2.50-$3.50 per watt. After the 30% federal ITC, the net cost is $10,500-$21,000. Costs vary by state, system size, panel brand, and roof complexity. Commercial systems cost $1.80-$2.80 per watt due to economies of scale.
Solar Financing Options
Cash purchase maximizes savings (full ownership, tax credit, no interest). Solar loans spread the cost over 10-25 years with monthly payments often lower than your current electric bill. Leases and PPAs require $0 down but you do not own the system or claim the tax credit.
Choosing the Right Installer
