In 2025, national average costs range from $2. 50 per watt before incentives. This price includes everything: solar panels, inverters, racking, electrical work, permits, inspections, and installation labor. . NLR analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. NLR's PV cost benchmarking work uses a bottom-up. . Prices stabilized in 2024-2025, and heading into 2026, we're seeing costs hold steady around $2. As a solar shopper, one thing you need to realize is that the quoted price isn't what you'll actually pay. This guide explains the price per watt, how system size and equipment quality affect your total cost, and the impact of labor and installation factors.
