Why Now Is the Best Time to Install Solar Panels
Equipment prices have stabilized, and federal and state incentives may help offset the upfront cost (eligibility and amounts vary and can change, consult a qualified tax professional). Utility rates have generally continued to climb, so the sooner you start generating your own power, the more you may save over time.
Solar Panel Lifespan and Maintenance
Quality solar panels are warrantied for 25 years and routinely produce power for 30+ years. Annual degradation is about 0.5 to 0.8%. Maintenance is minimal: an annual visual inspection, occasional cleaning, and monitoring to catch any anomalies early.
