6 FAQs about [Photovoltaic panels and obstructions]

What are the disadvantages of a photovoltaic system?

One disadvantage of photovoltaic systems is the occurrence of mismatch losses. These losses can result from differences in electrical characteristics between different PV cells or modules. Shadowing is a common cause of power losses in PV systems.

Why are photovoltaic modules more prone to stress?

The operating conditions of photovoltaic (PV) modules in built environments are more susceptible to additional stressors, such as shading and elevated temperatures, compared to those designed for large-scale installations in moderate climates [ 1 – 3 ].

Why should we invest in PV panels?

Despite the shadow problems, the installation and production of PV panels have seen significant growth worldwide. The bigger investment in PV technology brings more research to address the challenges in this sector. As a result, the benefits of PV panels continue to outweigh the drawbacks.

How does a solar PV system generate electricity?

Solar photovoltaic (PV) systems generate electricity via the photovoltaic effect — whenever sunlight knocks electrons loose in the silicon materials that make up solar PV cells. As such, whenever a solar cell or panel does not receive sunlight — due to shading or nearby obstructions — the entire installation generates less overall solar power.

What happens when a PV panel is shaded?

When a PV panel is shaded, it causes mismatch losses that can significantly reduce the power output of a photovoltaic power plant. To minimize this problem, some technologies are already available, such as bypass diodes and maximum power point tracking (MPPT) devices, like DC-DC optimizers.

Why do photovoltaic (PV) systems lose power?

Shadowing is the primary cause of power losses in PV systems. However, other factors such as differences in PV modules' operation conditions, module damages, and manufacturing differences can also contribute to mismatch losses. In the last ten years, the I-V mismatch occurring in PV arrays has decreased.
