Empowering Businesses: Economic and Environmental Benefits of Solar Energy in the USA Manufacturing Company

This research analyzes the economic and environmental performance of a rooftop photovoltaic (PV) system with an installed capacity of ۷۹۳.۱ kW in an industrial facility in New Hampshire - one of the U.S.'s most expensive electricity markets characterized by low solar irradiance. While most previous studies have relied on simulations or residential-scale systems, this research provides a firm-level, real-world benchmark using five years of operational and financial data (۲۰۲۰–۲۰۲۴). The deterministic analysis indicated a levelized cost of energy (LCOE) of ۰.۰۵۱۹/kWh, a payback period of ۷.۲۱ years, and a return on investment (ROI) of ۲۴۷%, along with an annual avoidance of ۳۸۲.۵ tons CO₂ emissions. To address uncertainty, a Monte Carlo simulation using ۱۰,۰۰۰ iterations examined capital cost, irradiance, electricity price escalation, and system degradation. The Monte Carlo results showed a median LCOE value of ۰.۰۵۲۳/kWh, ROI above ۲۰۰% in all ۱۰,۰۰۰ simulations, and payback of less than eight years in ۹۵% of iterations, all in ±۷.۲% variability; whereas ±۱۵% variability was reported elsewhere. This research demonstrates that industrial PV investments can achieve resilient, risk-adjusted returns under adverse conditions while offering a transferable framework for renewables in at-scale energy investment environments with high electricity market costs and low irradiance profiles globally.
