recently, LONGi eHome BIPV photovoltaic tile, a green energy household green power solution, won the 2026 German iF design award in the category of “product design/building technology.
the German iF Design Award was established in 1953 and sponsored by iF International Forum Design Company. It is famous for its” independent, rigorous and reliable “award criteria and is known as the” Oscar of design “. Since its inception, the award has always been one of the most authoritative benchmarks in the global design community.
This honor shows that the perspective of high-end home owners on solar roofs is changing. Photovoltaic products are no longer just power generation equipment, but become a part of the beauty of the residential building itself. For villa owners, they not only hope to obtain higher power generation income on the limited roof area, but also hope that the photovoltaic system can be naturally integrated into the architectural style, rather than destroying the overall beauty.
Traditional photovoltaic modules are often regarded as the “external equipment” of the building, which discourages many owners who pursue architectural aesthetics. The award of LONGi eHome BIPV product precisely responds to this pain point. LONGi’s design team deconstructed the photovoltaic power generation unit as part of the architectural language from the architect’s perspective. The product uses highly modular minimalist lines, dark matte texture and almost seamless splicing process, so that the solar roof is no longer an “add-on”, but like high-quality metal roofing or terracotta tiles, it has become the valuable “fifth facade” of the house itself “.
In addition to aesthetic design, LONGi eHome BIPV products also take into account the core concerns of high-end residences for long-term reliability. It meets the highest fire rating Class A requirements and provides a 30-year product and performance warranty. This means that the product is not only beautiful, but also forms part of the residential energy infrastructure and can operate stably for decades.
For home owners, the roof area is limited, and obtaining higher power generation in a limited space is the core demand. Relying on Longji’s high-efficiency battery technology, BIPV photovoltaic tiles achieve higher energy density per unit area. Even on the roof of a villa with a small area or limited structure, it can make a substantial contribution to reducing household electricity costs. With Longji home energy management system, users can monitor power generation, storage and electricity consumption data in real time, realizing the one-stop experience of “roof is power station, home is green electricity.
Climate adaptability is one of the core challenges facing household users around the world, and it is also a key assessment dimension for this jury. LONGi eHome BIPV products can withstand high snow and wind loads and pass rigorous hail tests. Its innovative building-grade waterproof structure makes the photovoltaic roof reach or even better than the traditional roof waterproof level; built-in ventilation and heat dissipation channels effectively reduce the working temperature of the components and reduce the loss of power generation. This means that the system can still operate stably and reliably even under increasingly extreme weather conditions such as heavy rain, snow, hail, and high temperature. For villa owners, this long-term security is as important as efficient power generation.
This award not only confirms Longji’s product strength and brand value in the BIPV field, but also further strengthens its long-term commitment to respond to the global energy transition and zero-carbon building trend with technological innovation and industrial design. As a global leader in BC technology, Longji is committed to transforming cutting-edge photovoltaic technology into an integrated solution with both power generation efficiency and architectural beauty, so that home users can enjoy green energy while also having a roof with both function and aesthetics.
With the growth of global demand for green buildings, household green electricity is moving from “minority attempt” to “mainstream choice”, while taking into account high efficiency, safety and architectural aesthetics, which is what LONGi eHome has always insisted on.
