What are the benchmarks for PV & energy storage systems?

The benchmarks in this report are bottom-up cost estimates of all major inputs to PV and energy storage system installations. Bottom-up costs are based on national averages and do not necessarily represent typical costs in all local markets.

How much does a solar system cost?

This translates to a range of $2.06– $12.37/kW/year, and a benchmark value of $3.44/kW/yr. for a 200-kW commercial rooftop system and $1.17–$7.02/kW/year, and a benchmark value of $1.95/kW/yr. for a 100 MW utility-scale single-axis tracking system.

How much does an AC-coupled Solar System cost?

Because AC-coupled systems have independent PV and battery systems with separate inverters, this hybrid configuration enables redundancy. For instance, if the battery-based inverter fails to operate, the PV system could operate independently as long as the grid is up. Total System Cost = $311.28*P + $300.24*P*H with an R squared value of 99.8.

What is the difference between EPC & EPC nonhardware?

Total system upfront capital costs are broken into EPC costs and developer costs. EPC nonhardware, or “soft,” costs are driven by labor rates and labor productivities.

Where can I find a summary of the solar cost analysis?

www.nrel.gov/solar/solar-cost-analysis.html. systems. Section 11 presents the results of our operations and maintenance (O&M) cost analysis. Section 12 uses our capital cost and O&M cost results to calculate the levelized cost of electricity (LCOE) for PV and PV-plus-storage systems. Section 13 offers a summary and conclusions.

Why do solar inverters cost more than AC-coupling?

Using DC-coupling rather than AC-coupling results in a 4.5% higher total cost, which is the net result of cost differences between DC-coupling and AC-coupling in the categories of solar inverter, DC-DC converter, and related structural and electrical balance of system costs.
