Onyx Solar recently teamed up with Butech to launch a new line of photovoltaic paving stones made from ceramic and glass. The streamlined solar stones are manufactured using a process that produces less CO2 and uses less energy than traditional pavement, making this energy-generating material even better for reducing the environmental impact of building projects. Onyx and Butech hope to release the tiles to market by the end of this year, making them the first PV pavement system available for purchase.
