Solar power generation maintenance costs

estimate operation and maintenance (O&M) costs related to photovoltaic (PV) systems. The cost model estimates annual cost by adding up many services assigned or calculated for each year. The PV O&M cost model assumptions and modeled cost drivers represent dependencies on system size and type, site and environmental conditions, and age.

All technologies demonstrate some degree of variability in cost, based on project size, location, and access to key infrastructure (such as grid interconnections, fuel supply, and transportation). For wind and solar PV, in particular, the cost favorability of the lowest-cost regions compound the underlying variability in regional cost and .

In addition to the typical focus of thinking about up -front costs of a solar plant, determining a plan and budget for operations and maintenance (O & M) is essential in assessing the business case for a PV facility.

For optimizing the balance between reducing operations and maintenance (O&M) cost and improving performance of photovoltaic (PV) systems, NREL collects data, models performance and costs, and provides expertise to industry.

The National Renewable Energy Laboratory and Sandia National Laboratories collaborated on the Model of Operation-and-Maintenance Costs for Photovoltaic Systems report, which presents a more detailed model for calculating the O&M expenses of PV systems using a system description to select from a list of detailed O&M measures, each of which .

6 FAQs about [Solar power generation maintenance costs]

Does operational and maintenance affect onshore wind and solar photovoltaic (PV) lifecycle costs?

In 2017, operations and maintenance (O&M) accounted for 20%–25% of lifecycle costs for wind and solar plants in Europe, but the understanding of O&M dynamics is limited. Presenting new data from Germany, here, we consider cumulative operating experience to estimate O&M experience curves for onshore wind and solar photovoltaic (PV).

Why are operations & maintenance costs important?

Given the decline in investment costs for renewable energy technologies, other cost components have become increasingly important. In 2017, operations and maintenance (O&M) accounted for 20%–25% of lifecycle costs for wind and solar plants in Europe, but the understanding of O&M dynamics is limited.

How much does solar PV cost?

In sum, solar PV O&M cost decreased from an average of 47.60 EUR 2017 /kW p /a in 2005 down to 7.05 EUR 2017 /kW p /a in 2017, a remarkable reduction of 85% (Figure 4 B). Point estimates for experience rates (Figure 4 C) are between 15.7% and 18.2%, and the confidence intervals are much smaller than for onshore wind.

Are solar PV projects reducing the cost of electricity in 2022?

Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.

What is a life cycle cost and optimization of PV systems?

The National Renewable Energy Laboratory’s Life-Cycle Cost and Optimization of PV Systems Based on Power Duration Curve with Variable Performance Ratio and Availability report provides a mathematical functional form for the annual power duration curve for the output of a photovoltaic power system with imperfect performance ratio and availability.

What is a PV O&M cost model?

The PV O&M cost model assumptions and modeled cost drivers represent dependencies on system size and type, site and environmental conditions, and age. Also, a detailed cost model allows investigation of how costs change over a very long performance period.
