Solar Photovoltaic Panel Bubble Elimination

This work focuses on analyzing the bubbles formation on the front of the PV module, particularly on the fingers of the PV cells. The paper investigated several PV modules operating in Algeria under two different weather conditions (warm and dry climate, moderate and humid climate) for almost 30 years.

Solar panels are therefore cleaned regularly using large quantities of pure water. Consumption of water for cleaning, especially in deserts, poses a substantial sustainability challenge. Here, we present a waterless approach for dust removal from solar panels using electrostatic induction.

According to Munoz et al. (2011), the bubbles impede the heat dissipation of the cells, increase the overheating, reduce the lifespan of the module, decrease the solar irradiance absorption, and increase the reflection of sunlight on the photovoltaic module.

Bubbles in solar panels, often referred to as delamination, can occur due to a variety of reasons, including manufacturing defects, poor installation practices, or environmental factors. Here are some common causes of bubbles in solar panels and preventive measures.

Results showed that the efficiency of the PV panels reduced by 50% when it was cleaned with normal water, whereas the efficiency remained the same when a mixture of anionic and cationic surfactants is used. Sabah and Faraj (2013) is a brief article emphasizing on the importance of cleaning PV panels.

6 FAQs about [Solar Photovoltaic Panel Bubble Elimination]

What causes bubbles in a photovoltaic module?

Bubbles are probably the results of an electrochemical reaction involving oxygen. Understanding photovoltaic modules degradation is one of the keys utilized to develop and design new high-performance materials. This work focuses on analyzing the bubbles formation on the front of the PV module, particularly on the fingers of the PV cells.

Why do PV cells have bubbles in the encapsulant?

During the visual inspection, the formation of bubbles was observed only in the encapsulant above the PV cells within the PV module. However, these bubbles position is consistent with other defects, such as chalking, browning, and bleaching, indicating that these bubbles are distinct from those usually observed. 1. Introduction

Can water based cleaning improve the efficiency of PV panels?

The article in Katakam et al. (2019) proposes a water based cleaning technique for PV panels. The cleaning is achieved by the water being sprayed from the top of the panel through closely placed nozzles only. An increase in efficiency by 1.2%–3% was achieved.

How useful are chemical solutions and electrical performance analysis of solar PV panels?

The usefulness of the chemical solutions and electrical performance analysis results of solar PV panels were validated by measurements and tests. The amount of power generation was increased by 15% from the PV panel cleaned using proposed solution. Fig. 12. Solar panel cleaning using cleaning robots. Table 4.

Could atmospheric water generators be a sustainable solution for solar PV panel cleaning?

Atmospheric water generators could be a valuable addition to the proposed sustainable setup to overcome issues for more efficient and sustainable solar PV panel cleaning systems (Naffa’a and Al Jabri, 0000).

Is solar panel cleaning a sustainable solution?

PV panel cleaning - A possible sustainable solution. (2) Significance of Automated Cleaning: The advantage of automated cleaning is a green solution promoting decarbonization. Moreover, minimal maintenance is required in automated cleaning while enhancing the power efficiency of solar panels.
