6 FAQs about [The impact of photovoltaic super-matching inverters]

How does inverter loading affect solar energy losses?

Solar energy losses from clipping increase rapidly with increasing inverter loading ratios. Higher inverter loading ratios lead to larger and more frequent solar ramping events. Over time, module degradation mitigates some of the losses due to inverter sizing.

What are the disadvantages of a solar inverter?

The drawback to increasing a project’s ILR occurs when the inverter is power limiting (i.e., when the power from the solar array exceeds the inverter’s rated input power). Termed clipping, the time when inverters are power limited serve to reduce and flatten the system’s output during the times of highest production.

How do inverter loading ratios affect solar output?

Fig. 5. Solar generation duration curves for selected inverter loading ratios (ILRs). In addition to impacting project generation and inverter utilization, higher ILRs also impact the incidences of high ramp rates associated with solar output.

Why are PV inverters becoming more efficient?

The new generation of PV inverters are becoming more efficient, with efficiencies greater than 97% The efficiency is brought about by changing the topology of the power converter or control scheme or by better circuit board layout techniques.

Why do solar inverters have a higher ILR?

Higher ILRs increase the utilization of the inverter, thereby decreasing the inverter costs per kW h of AC output. The drawback to increasing a project’s ILR occurs when the inverter is power limiting (i.e., when the power from the solar array exceeds the inverter’s rated input power).

Should a solar inverter rating be increased?

When designing a solar project, increasing the ILR is one option that developers may consider to decrease the unit cost of electricity and increase the effective capacity factor relative to the inverter rating. A complete analysis for such a developer would also include an assessment on the impacts of higher ILRs on inverter longevity.
