Breaking Down BIPV: A Case Study on Simplified Electrical Systems

Building-integrated photovoltaics (BIPV) are transforming how buildings harness solar energy by seamlessly blending solar technology with façades, windows, and other structural elements. A common misconception among building owners is that BIPV installation requires a complex electrical setup. This case study challenges that belief, showcasing how both eFacade PRO and eFacade LITE from Mitrex provide accessible, flexible installation options for sustainable energy solutions.

A Simple Electrical Design with eFacade PRO (50kW System)

For those looking to integrate BIPV in a way that works with existing electrical systems, eFacade PRO offers a solution that’s both efficient and straightforward. In this case, a typical 50kW eFacade PRO system demonstrates how BIPV can be installed with minimal complexity:

• Inverters: This 50kW system typically uses three 17.3kW inverters to convert DC to AC power, providing an efficient and reliable energy conversion setup.
• Disconnects and Panelboards: Basic 240V disconnects and panelboards keep the system compact without requiring additional complexity.
• Conduit and Wiring: A single 2-inch conduit routes the DC wiring, requiring just one structural penetration, which simplifies installation and minimizes impact on the building’s design.

This streamlined approach with eFacade PRO ensures that the electrical requirements are straightforward, reducing both time and space needed for installation in a larger, commercial-grade 50kW system.

Plug-and-Play with eFacade LITE

For building owners who prioritize ease of installation, eFacade LITE offers an even simpler, plug-and-play option. This innovative system eliminates visible panel-to-panel wiring, further reducing the complexity of setup. Here’s what makes eFacade LITE distinct:

• Single-Wire Connections: Each solar module connects directly to a power bar, removing the need for extensive on-site wiring.
• Quick Installation: With its plug-and-play design, eFacade LITE ensures a fast, cost-effective installation that preserves the building’s aesthetic.

eFacade LITE is particularly suited to projects demanding rapid installation without compromising on functionality, making it a strong choice for both new constructions and retrofits.

Space Efficiency Without Sacrifice

Both eFacade PRO and eFacade LITE maximize building space by integrating solar panels into surfaces like façades and windows. Unlike traditional rooftop arrays that occupy valuable real estate, these BIPV systems provide sustainable energy without disrupting the building’s layout or aesthetics. In this case, the components were placed compactly on the building’s rooftop, preserving the design and minimizing spatial impact.

Key Insights: Flexibility in BIPV Solutions

Mitrex’s BIPV offerings give building owners flexible options tailored to their needs:

• eFacade PRO: Designed for projects that integrate seamlessly with existing electrical systems, making it ideal for those who need a larger, commercial-grade system like the 50kW setup.
• eFacade LITE: Suited for clients prioritizing simplicity with its plug-and-play system, providing a hassle-free installation that eliminates complex wiring.

By offering both eFacade PRO and eFacade LITE, Mitrex enables building owners to adopt sustainable energy in a way that aligns with their preferences—whether that means integrating with traditional electrical setups or choosing a simplified, wire-free solution.
