Maintenance costs of solar power generation

Solar array maintenance: why are costs falling?Costs halved in a decade Based on a compilation of published reports, Andy Walker from the US-based National Renewable Energy Laboratory (NREL) estimates that, for old solar PV systems, O&M was on average $20 per kW a year, whereas now it is closer to $7.50 per kW a year. New innovations . People management and logistics handling . Remaining challenges .

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.

In 2023, the global weighted average levelised cost of electricity (LCOE) from newly commissioned utility-scale solar photovoltaic (PV), onshore wind, offshore wind and hydropower fell. Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%).

To accelerate the deployment of solar power, SETO has announced a goal to reduce the benchmark levelized cost of electricity (LCOE) generated by utility-scale photovoltaics (UPV) to 2¢/kWh by 2030. 3 In parallel, SETO is targeting a 2030 benchmark LCOE of 4¢/kWh for commercial PV, 4 5¢/kWh for residential PV, 5 and 5¢/kWh for concentrating .

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. NREL's PV cost benchmarking work uses a bottom-up approach. First, analysts create a set of steps .

6 FAQs about [Maintenance costs of solar power generation]

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 is maintenance management important for PV power plants?

Therefore, maintenance management is essential for reliable and effective operation of PV power plants, ensuring uninterrupted system operation and minimizing downtime. Compared to well-established technologies such as hydro, thermal, and wind, the O&M processes for PV systems are not yet fully structured in many operating companies .

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.

Why do solar power plants need maintenance?

However, following this approach often leads to unexpected failures, production losses, higher costs, and compromised power quality . Consistent management and maintenance of large-scale solar power plants are crucial to ensure grid stability, which goes beyond individual solar arrays.

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.
