Solar panel costs range from $16,600 to $20,500 for the average 6.5 kW system, but prices can vary from as little as $7,700 for smaller solar systems to upward of $34,700 for larger systems.
Average price of solar modules, expressed in US dollars per watt, adjusted for inflation.
NLR analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. This work has grown
Historic Low Pricing: Solar costs have reached unprecedented lows in 2025, with systems ranging from $2.50-$3.50 per watt installed, making the technology more accessible than ever before.
Calculating solar price per watt is pretty simple. Simply divide the cost of the system (in dollars) by the size of the system (in watts). PPW = System cost / System wattage. Now, solar systems are typically
