A review of various manufacturers and options allows for an estimation of the price range associated with solar photovoltaic grid-connected cabinets. Market analysts routinely monitor and report the average cost of PV systems and components, but more detail is needed to understand the impact of recent and future technology developments on cost. Consequently, benchmark systems in the utility-scale, commercial, and residential PV market sectors. 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 to include cost models for solar-plus-storage systems. Distributed Solar and Storage annual data update).

As of 2025, prices range from $0. 86 per watt-hour (Wh) for utility-scale projects, while residential systems hover around $1,000–$1,500 per kWh.

What is PV system cost model (pvscm)?
The total cost over the service life of the system is amortized to give a levelized cost per year. In the PV System Cost Model (PVSCM), the owner's overnight capital expense (cash cost) for an installed PV system is divided into eight categories, which are the same for the utility-scale, commercial, and residential PV market segments:
Colocating the PV and storage subsystems produces cost savings by reducing costs related to site preparation; land acquisition; permitting and interconnection; installation; labor; hardware (via sharing of hardware such as switchgears, transformers, and controls); overhead; and profit.
13 For a 1-MW PV system with an inverter loading ratio of 1.3 and inverter/storage size ratio of 1.67, maximum deliverable power at point of interconnection is 1.37 MWAC (1-MW/1.3 + 1 MW/1.67) for AC-coupled systems and 770 kWAC (1 MW/1.3) for DC-coupled systems. National average modeled labor rate assumes nonunionized labor.
With AC-coupling, the price of the system is $33,756, which is $3,306 (10.9%) more than the price of the DC-coupled system ($30,450). Figure 16. Modeled total installed cost and price components for residential PV-plus-storage systems, DC-coupled versus AC-coupled case (2020 USD)
