What causes energy production loss in solar PV systems?

In today’s article, the latest installment of Aurora’s PV System Losses Series –in which we explain specific causes of energy production loss in solar PV systems–we explore losses from tilt and orientation, incident angle modifier, environmental conditions, and inverter clipping.

What are solar power losses?

Soiling losses: Soiling losses refer to loss in power resulting from snow, dirt, dust and other particles that cover the surface of the PV module. Dust is a thin layer that covers the surface of the solar array, and the typical dust particles are less than 10 µm in diameter but this depends on the location and its environment.

Why do solar panels lose power?

The quantity of sunlight that is obstructed by dirt and debris that accumulates on solar panels over time, resulting in a loss of power, is referred to as soiling loss (Jamaly et al., 2013). Several factors influence photovoltaic systems. These include location, orientation, and the environment.

Are solar panel losses minimized?

Several studies have provided general reviews on the minimization of losses in PV systems. For instance, Song et al. (2021) reviewed key studies that deal with reduction in solar panel efficiency, the causes of these degradations and the crucial methods for mitigating the unfavorable consequences of these losses.

What causes a PV system to lose power?

Panel degradation causes around 0.8% in power losses every year. As we have seen, most of the causes of PV system losses are related to design factors or component characteristics. Project designers should be mindful and choose the right cabling, as well as limit shading effects.

How to reduce solar panel shading losses?

As an installer, there are a number of solar design strategies you can use to reduce shading losses. These solar panel shading solutions include using different stringing arrangements, bypass diodes, and module-level power electronics (MLPEs). 1.
