LCOE

Acronym for: Levelized Cost of Electricity

Summary

Total lifetime cost of building and operating a solar plant divided by total lifetime energy generated.

Detailed Explanation

LCOE (Levelized Cost of Electricity) is the standard metric for comparing electricity generation economics across technologies. Formula: (total lifetime costs) / (total lifetime energy). In 2026, utility-scale solar LCOE ranges $0.02-0.05/kWh globally, making it the cheapest new electricity source in most markets. Lower LCOE = more competitive. Inputs include: capex, operations costs, financing cost, capacity factor, degradation, lifetime. Choosing TOPCon over PERC lowers LCOE 5-8% due to higher yield and slower degradation.
