- THIN-FILM PANELS
Thin-film solar panels are characterized by their lightweight and flexible construction, which involves depositing layers of photovoltaic materials onto substrates like glass, metal, or plastic. These panels allow for diverse applications and configurations, especially in unconventional installations where traditional panels may not be suitable. For instance, thin-film technology is beneficial for integrating into building designs for aesthetic purposes, offering versatility not found with rigid panels.
Despite their flexible nature, thin-film panels generally exhibit lower efficiency, averaging around 10-12%. This lower efficiency necessitates larger installations to achieve comparable energy production, which could be a limitation for some projects. However, thin-film technology has developed over the years, leading to enhanced performance and attractiveness for specific use cases. Conditions such as high temperatures or shading lessen the impact on thin-film panels, making them suitable for environments where other types may falter. This resilience, combined with their lightweight characteristics, presents a unique advantage in specific applications.
- BIFACIAL PANELS
Bifacial solar panels are an innovative design advancement that allows for energy collection from both the front and rear sides of the panel.
