By minimizing light absorption, low-iron glass increases energy yield and overall solar panel effectiveness.
According to the National Renewable Energy Laboratory (NREL), low-iron glass significantly improves the transmittance of solar radiation, which is crucial for maximizing the absorption of sunlight in photovoltaic cells.
The underlying reasons for the importance of low-iron glass in solar applications include its high light transmittance and low iron content. Iron in standard glass can create a greenish tint that restricts sunlight transmission. This decrease in transmitted light can reduce the energy conversion efficiency of solar panels. Low-iron glass, with its clearer composition, ensures more light reaches the panel’s solar cells.
Low-iron glass is defined as glass that has a lower content of iron oxide compared to regular glass. This results in high visible light transmittance, typically above 90%, which is crucial for solar applications. The technical term “visible light transmittance” refers to the percentage of visible light that can pass through a material.
The mechanisms involved in the efficiency of low-iron glass include its ability to minimize reflection and maximize transmission. When sunlight strikes the glass surface, some light reflects back while the remainder passes through. Low-iron glass reduces reflective loss due to its composition, thus allowing more light to enter the solar cell, which converts it into electricity.
Several conditions can enhance the effectiveness of low-iron glass. For example, using this glass in sunlight-rich environments, such as areas with high solar insolation, maximizes energy output. Scenarios where low-iron glass is beneficial include residential rooftop solar installations and large-scale solar farms. In these cases, the clear, low-iron glass helps achieve higher energy returns compared to standard glass, leading to improved system performance.
