Interpretation
Technology, Performance & Reliability Interpretation
Solar panels mostly turn “sun into usable electricity” with common silicon module efficiencies around 20% to 23%, while the lab keeps one-upping itself (26.1% for monocrystalline silicon and 33.7% for perovskite/silicon tandems), and then reality starts charging you rent through degradation of roughly 0% to 0.5% per year after the usual first year dip, heat that can shave about 0.3% per °C (PVWatts even assumes a bit more at -0.4% per °C), and system losses that can stack up around 14% plus a PVWatts default derate factor of 0.77, meaning the “rated” power is less a promise than a best-case scenario that still has to pass IEC 61215 gauntlets like cycling between -40°C and +85°C, 85°C damp heat at 85% humidity for 1000 hours, and hail testing with a 25 mm steel ball at 23 m/s, all while warranties quietly point you toward “90% at year 10, 85% at year 25,” and keep performance expectations anchored to U.S. utility-scale capacity factors of about the mid 20s percent.
