Photovoltaic Glass

mitrex technology
The efficiency of building-integrated photovoltaics relies on the level of light transmitted through the glass to the photovoltaic layer. When colours or patterns are applied to the protective glass layer of a solar panel, light transmittance is affected. We study the natural interaction of light and pigment, paying close attention to the reflective and absorbent properties of colour to optimize efficiency and aesthetics. This balance between beauty and efficiency requires us to perpetually innovate photovoltaic glass.
Mitrex surface glass undergoes an extensive multilayered coating process through an atmospheric process.

This process colour-treats the glass through the application of highly efficient and environmentally-friendly pigments optimized for photovoltaics. The coloured layers are fused into the glass, allowing us to produce any design required. The glass coating materials are characterized by high solar transmittance, minimal absorption, and increased durability. Treated glass can have reflective, semi-reflective, or matte surfaces, depending on the product’s aesthetic requirements.

Coatings

To achieve both efficient power generation and an aesthetically pleasing design, Mitrex pays special attention to coatings. An anti-reflection coating is applied to prevent sunlight from reflecting off the glass. An anti-soiling coating prevents sunlight-blocking dust from settling onto the glass. The anti-soiling coating also makes Mitrex products virtually maintenance-free.

Solar Cell

Mitrex technology builds upon regular solar panels by combining them with building materials, making them multi-purpose products. At Mitrex, we prioritize the high efficiency of the solar modules while maintaining design flexibility.

Solar Back Sheet

A solar back sheet plays a significant role in protecting the module and ensuring the lifetime of the system. A poorly engineered back sheet can result in power degradation of the modules and safety failures that can cause injuries. The back sheet is the only layer protecting people from dangerous DC voltage. It also protects the module from UV radiation, chemical corrosion, and oxygen or moisture penetration while providing electrical insulation of the system. An ideal back sheet balances the weatherability, mechanical strength, and adhesion to the module.

At Mitrex, we only use the highest quality back sheets to ensure our modules last over 25 years. Our back sheets are a triple layer fluorine/PET/PVDF sandwich that balance all three attributes while staying extremely thin (300 m). Back sheets are available in white (for more power of approximately 10 W) or black for a sleeker look.

Aluminum Honeycomb

Mitrex solar panels are reinforced by an aluminum honeycomb backing. Our aerospace technology takes advantage of the lightweight and durable structure of the honeycomb. This makes our cladding significantly lighter compared to traditional cladding options and increases the safety and durability of the building facade. Compared to a conventional solar frame, the aluminum back acts as a heat sink which helps cool the panels. Solar panels operate better in cooler conditions, as they lose approximately 0.3-0.4% of power per degree Celsius when the temperature reaches over 25°C. The honeycomb is also more durable than a traditional frame, making it more resistant to wind and snow. Overall, the honeycomb structure means that our panels are structurally more robust and resilient than conventional framed panels.

Inverters

For the entire solar system to provide energy, an inverter is required. An inverter is an electronic device or circuitry that converts direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the specific device or circuitry design. The inverter does not produce any power; the power is provided by the DC source, in this case, the Mitrex PV modules. Inverters are essential for solar systems because they convert the DC electricity produced by the modules into AC electricity for the grid.

Mitrex BIPV modules have a range of 10V to 50V. These systems are compatible with almost all the inverters on the market; microinverters for smaller projects, string inverters, and central inverters can be used with our products. Mitrex solar modules have a maximum voltage system of 1000V, meaning they are compatible with 600V in put voltage inverters, particularly for residential building applications, and 1000V input voltage. Also, Mitrex products are compatible with DC power optimizers
