In the field of solar panel testing, sun simulators play a crucial role in evaluating the performance and efficiency of photovoltaic devices under controlled conditions. To ensure accurate and reliable results, these simulators must closely replicate the spectral distribution of natural sunlight. KUPO Optic's advanced AM (Air Mass) filters are specifically designed to optimize sun simulators, enabling them to reproduce the solar spectrum with exceptional precision and consistency.

AM filters are essential for simulating the effects of the Earth's atmosphere on sunlight, as the spectral distribution of light changes as it passes through the atmosphere. KUPO Optic offers a range of AM filters, including AM0, AM1.5G, and AM1.5D, each tailored to specific testing requirements. AM0 filters simulate the solar spectrum outside the Earth's atmosphere, making them ideal for testing solar panels designed for space applications. AM1.5G filters, on the other hand, simulate the global average solar spectrum at the Earth's surface, taking into account both direct and diffuse light. This makes them the most commonly used filters for testing terrestrial solar panels. AM1.5D filters focus on direct sunlight, making them suitable for testing solar concentrator systems. By incorporating these AM filters into sun simulators, researchers and manufacturers can ensure that their solar panels are tested under conditions that accurately represent real-world performance.
