That’s a great step you’re taking! When comparing solar panels, the key technical aspects to evaluate are efficiency rating (typically 18–23%), temperature coefficient (how much performance drops in heat), degradation rate (annual efficiency loss), and warranty terms (often 20–25 years). Also, don’t overlook inverter compatibility and local installation standards, since these affect long-term reliability.
