NREL 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 to include cost models for solar-plus-storage systems. Since 2010, NREL has benchmarked the full cost of PV systems—including installation—for residential and uti.

Solar energy cost analysis examines hardware and non-hardware (soft) manufacturing and installation costs, including the effect of policy and market impacts. Solar energy data analysis examines a wide range of issues such as solar adoption trends and the performance and reliability of solar energy generation facilities.
The average cost of BOS and installation for PV systems is in the range of USD 1.6 to USD 1.85/W, depending on whether the PV system is ground-mounted or rooftop, and whether it has a tracking system (Bony, 2010 and Photon, 2011). The LCOE of PV systems is therefore highly dependent on BOS and installation costs, which include:
How much does solar energy cost in 2022?
Again, the average annual energy bill in 2022 was approximately $1,600. Since the average solar system costs between $10,200 and $15,200 after the tax credit, it could take you anywhere from 6.4 to 9.5 years to break even on the cost of your solar energy system.
How is the cost of a solar system determined?
The cost of the electricity generated by a PV system is determined by the capital cost (CAPEX), the discount rate, the variable costs (OPEX), the level of solar irradiation and the eficiency of the solar cells.
The cost of solar panels ranges anywhere from $8,500 to $30,500, with the average 6kW solar system falling around $12,700. It's important to note that these prices are before incentives and tax credits are applied. We found that solar panel prices vary based on where you live, the size of the system, the type of solar panels and more.
Depending on which state you live in, your average 6kW solar panel system will cost between $10,200 and $15,200 to install after accounting for the 30% solar tax credit. However, we know that every home has its own energy demands, and prices for solar panels can quickly increase or decrease based on the size of your system.
