According to the US Department of Energy's benchmark data, the average cost to install a residential rooftop solar system without an energy storage system is around $2,737 per kilowatt or $2. . Strong Long-term Returns: Despite upfront costs, solar systems typically save $20,000-$60,000 over 25 years while increasing home values by approximately $15,000, making them one of the most reliable home improvement investments available. Solar panel costs have reached historic lows in 2025. . NLR analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. Cost per. . Each year, the U. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U. solar photovoltaic (PV) systems to develop cost benchmarks. Battery storage represents the largest expense in an off-grid system, often accounting for 30-40% of the total system cost.
