The old 30% homeowner credit is gone, but that does not automatically mean solar stopped making sense. Here is how the new math works.

Solar panel choices generally fall into two very different categories: small DIY kits for sheds, RVs, or supplemental power, and full rooftop systems sized to offset most or all of a home's electricity use. These have different buying processes - DIY kits are purchased like any other product, while rooftop systems usually involve a quote, site assessment, and professional installation. Knowing which category you're in changes what matters most.
For shed, RV, or supplemental DIY kits, look at panel wattage, the included charge controller and mounting hardware, and whether the kit can be expanded later by adding more panels to the same system. Confirm your mounting surface (roof type, ground space, or RV roof) is compatible with the included hardware - mismatched mounting hardware is one of the most common DIY frustrations.
For full rooftop installations, request quotes in terms of system size (kW) and estimated annual production (kWh/year), not just total price. A lower-priced quote for a smaller system may produce less electricity than a higher-priced quote for a larger one - compare cost per kWh produced over the system's life, not just the upfront number.
Panel efficiency (the percentage of sunlight converted to electricity) affects how much power you get from a given roof area - higher efficiency matters more if your roof space is limited. Warranty length (often 25 years for panel output) is a strong signal of how long the manufacturer expects the panels to perform - shorter warranties may indicate lower-tier components, even if the upfront price looks attractive.
The homeowner 30% federal solar credit ended after December 31, 2025, so new 2026 rooftop projects should be evaluated without that assumption. Focus instead on gross installed cost, local utility rules, net metering, and any current state or utility rebates that still apply in your market.
