Solar Energy Guide
How Solar Works
Solar panels convert sunlight into electricity. Excess power can be sent to the grid for credit (net metering). Most systems include a battery backup option for energy independence.
Federal Tax Credit
The federal government offers a 30% tax credit (ITC) for residential solar installations through 2032, then 26% in 2033, and 22% in 2034. This significantly reduces upfront costs.
System Lifespan
Solar panels typically last 25-30 years with minimal maintenance. Most manufacturers offer 25-year warranties. Panel efficiency decreases slowly over time (0.3-0.8% annually).
Getting Started
Get 3-5 quotes from certified installers, check for local incentives, ensure your roof is suitable, and consider financing options like loans or leases. Solar increases home value by an average of $15,000.
