High-tech mobility innovator Lightyear and Royal DSM will jointly scale the commercialization of Lightyear’s unique solar-powered roof for the electric vehicle market. With this solution, both companies aim to accelerate the global adoption of a broad range of Electric Vehicles (EVs).
Specifically, the partnership aims to integrate solar-powered roofs in a variety of electric vehicles, including cars, vans and buses, thus enabling users to charge their vehicle directly with clean energy. The companies are teaming up to assess the market, starting with pilot projects for customers from the automotive and public transport sector, where the integration of a solar roof could represent a smart investment.
The global EV market was valued at $160-plus billion in 2019; and is projected to reach $800-plus billion by 2027 according to international market assessments from Bloomberg, IDTechEx and TIME. To accelerate this growth, the EV industry now needs to overcome the twin hurdles of limited range and grid-dependency.
The alliance between Lightyear and DSM addresses this need by enabling various EVs to increase their range through energy harvested directly from the sun. The integration of a solar roof is expected to be a good investment in multiple EV market segments.
This technology was initially developed by Lightyear for the solar panels of Lightyear One. Lightyear One is set to be the world’s most efficient long-range solar car when it launches in 2021, with a WLTP range of 725 km (450 miles). Featuring five square meters of integrated solar cells protected by double-curved and super-strong safety glass, the solar roof captures sunlight continually whether the car is moving or stationary. The result is that in optimized vehicles like Lightyear One, the solar roof can deliver enough energy to cover an average of 70-90% of the yearly mileage.
DSM’s conductive backsheet is an integral element of the solar roof—enabling all the connections of the solar cells to be put on the back of the solar panel—thus making every available centimeter on the front of the module available for capturing sunlight. The reduction in electrical (cell-to-module) losses not only delivers a 3% increase in power output; it has the added advantage of contributing to a more stylish sunroof with aesthetic appeal.
