Our operations and maintenance (O&M) analysis breaks costs into various categories and provides total annualized O&M costs. The MSP results for PV systems (in units of 2022 real USD/kWdc/yr) are $28.78 (residential), $39.83 (community solar), and $16.12 (utility-scale).
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:
The current MSP benchmarks for PV systems in 2022 real USD are $28.78/kWdc/yr (residential), $39.83/kWdc/yr (community solar), and $16.12/kWdc/yr (utility-scale, single-axis tracking). For MMP, the current benchmarks are $30.36/kWdc/yr (residential), $40.51/kWdc/yr (community solar), and $16.58/kWdc/yr (utility-scale, single-axis tracking).
Market prices can include items such as smaller-market-share PV systems (e.g., those with premium efficiency panels), atypical system configurations due to site irregularities (e.g., additional land grading) or customer preferences (e.g., pest traps), and specific project requirements (e.g., unionized labor).
The IEC 62109 series of standards, one of the most authoritative and widely used worldwide, outlines the safety requirements, test methods, and energy efficiency indicators for inverters. Core Aspects of the IEC 62109 Standard. Note: All potentials indicated relative to negative DC! These DC fault currents MUST NOT be mixed up with DC current injection!
