Achieves up to 20 per cent lower levelised cost of electricity than competing technologiesSolar panels and systems manufacturer SunPower has launched the SunPower C7 Tracker, a solar photovoltaic tracking system that concentrates the sun’s power seven times to achieve the lowest levelised cost of electricity (LCOE) for utility-scale solar power plants available today.
The C7 Tracker combines single-axis tracking technology with rows of parabolic mirrors, reflecting light onto 22.8 per cent efficient SunPower Maxeon solar cells, which are the world’s most efficient commercially available solar cells. Using mirrors to reduce the number of solar cells required to generate electricity lowers the LCOE by up to 20 percent compared to competing technologies. For example, a 400-megawatt C7 Tracker power plant requires less than 70 megawatts of SunPower solar cells.
