About Us

We set new efficiency standards

Cat5 Group provides comprehensive solutions with the highest efficiency, dedicated to passive construction, which can be used both in individual single-family houses and in large construction investments – housing estates and industrial buildings.

Innovative, unique, ecological and with the highest efficiency – these are the solutions we focus on.

The group consists of Cat 5 Building Systems and Cat5 Solar


CAT5 Solar

CAT5 Solar founded in 2018 in the USA, provides intelligent and sustainable energy solutions.

We work with partners both in the United States and Europe, constantly working to improve the current technology using MWT cells. Our systems stand out positively from the competition, combining a full set of technically advanced photovoltaic and battery solutions that can provide energy 24 hours a day, in both small and large formats. In addition to traditional support for existing power grids, they also work well where there is no power grid. Our lightweight solar panels were developed in 2016 by fusing rail links onto a fiberglass plate. They have since been refined and are arguably some of the best solar panels in the world. They were created using MWT technology, with an additional power generation of 8.6% and a degradation of only 4.3% over a period of 44 years. These lightweight panels are almost indestructible as they are made of plastic. Upon impact, it does not break in its entirety, only the part that was directly hit breaks, and the rest of the cells in the panel continue to work normally.

Due to their light weight, they can be mounted on virtually any surface, even on small roofs.

Cat5 Solar provides advanced solutions for many industries that achieve great results in terms of both energy saving and generation.


Cat5 Building Systems

Cat5 Building Systems provides proprietary building solutions. The buildings are made of concrete blocks and EPS boards, they are resilient, sustainable and extremely energy efficient. Using the products of our sister company Cat5 Solar, we are able to create passive buildings.

The Cat5 system was developed in the USA and first used in Orlando, Florida in 2005 – it helped many affected residents who lost their homes in the Catrina tornado.

Another advantage of Cat5 building systems is that 80% of the structure can be built without skilled workers, in roughly half the time it takes to erect a traditional building. The U-factors of the building envelope are less than 0.04 and the materials used are fully recyclable. Thanks to these properties, the buildings are completely safe and energy efficient.

A system of concrete blocks and expanded polystyrene, Cat5 is suitable for buildings up to 8 storeys high, and the EPS solution up to 5 storeys. EPS is designed specifically for filling walls in multi-storey buildings, for internal walls, for insulating tilting wall systems, and for the construction of light warehouse and residential structures.
