A team of researchers from the University of Exeter in England have developed a solar power device that fits into glass blocks. The application, called Solar Squared, is particularly significant in helping to design to net-zero energy, say the researchers. The product can broadly replace glass blocks used for a building’s façade, and transform the exteriors into energy-generating surfaces. The optical elements incorporated in the Solar Squared blocks direct sunlight onto the solar cells to generate electricity. This electricity can then be stored in a battery system, supply energy to the building in real time, or be used to charge electric cars. Unlike existing solar products that generally require a large surface area and have an unpleasant appearance, this product seamlessly integrates into any design where you would have used a non-solar glass-block construction.
But there are challenges. The team hopes to register Solar Squared with the Building Information Modeling database, which would help provide broad access to architects and professionals in the building industry. According to Hasan Baig, a research fellow at the university's Environment and Sustainability Institute, “[the database] provides a list of all construction products available, their possible uses, and potential energy savings.” To achieve that, the team is in negotiation with the National Solar Centre and Building Research Establishment.
To pursue the research further, in collaboration with Glass Block Technology, the team has developed an independent spin-off company called Build Solar. The research team is optimistic that it can expand the scope of the project, and have the technology adapted for use in other construction materials.
Solar Squared will come in a variety of colorways and patterns, and should be on the market in 2018.
