6 FAQs about [Photovoltaic support construction loss rate]

Why do photovoltaic systems underperform expectations?

Photovoltaic systems may underperform expectations for several reasons, including inaccurate initial estimates, suboptimal operations and maintenance, or component degradation. Accurate assessment of these loss factors aids in addressing root causes of underperformance and in realizing accurate expectations and models.

Why do we need a performance guarantee for a large photovoltaic system?

Documentation of the energy yield of a large photovoltaic (PV) system over a substantial period can be useful to measure a performance guarantee, as an assessment of the health of the system, for verification of a performance model to then be applied to a new system, or for a variety of other purposes.

What are the key performance indicators for photovoltaic systems?

The mass deployment of photovoltaic (PV) systems requires efficient and cost-effective operation and maintenance (O&M) approaches worldwide. This includes the reliable assessment of certain key performance indicators (KPI) such as the energy yield, performance ratio (PR), performance index (PI), availability and performance loss rate (PLR).

How long do PV systems last?

PV systems remain in service for decades, making it important to plan for performance changes. There are a wide variety of factors that affect performance causing it to change over time. Quantifying the impacts of these losses is critical to reducing the financial risks of PV systems.

Why is inverter saturation common in commercial PV systems?

Curtailment is commonly used to stabilize the power output of PV plants and increase the capacity factor, making the systems easier to integrate into existing grids, but proactive curtailment can lead to reduced availability. As such, inverter saturation is most commonly observed in larger scale commercial PV systems.

How much CIS does a PV system have?

95 % Cis on a single system as we do in this report. A PV system fleet owner wanting to determine which systems are exhibiting similar or distinctly different performance loss, should graphically compare the overlap of 83.4 % Cis, and in Figure 22 we show these results for comparing across the PV systems in this study.
