Magenta solar panels aid agrivoltaics
The gist
Researchers at Sweden's Mälardalen University found broccoli under magenta semi-transparent solar panels used sunlight about 4.5 times more efficiently than open-field crops.
The panels also generate electricity on the same land, though the broccoli took 25 extra days to mature.
How it unfolded
- Oct 2, 2026Study led by researcher Silvia Ma Lu, published in Cell Reports Physical Science, reported broccoli under magenta panels used sunlight roughly 4.5 times more efficiently than open-field broccoli, though it took 25 days longer to mature.
- Oct 7, 2026Mälardalen University researchers in Västerås, Sweden, reported the roughly 4.5-fold light-use efficiency gain for broccoli under the panels.
- Oct 16, 2026Reports said the broccoli needed an additional 25 days to harvest but produced roughly the same yield, with light-conversion efficiency up 2.8- to 4.5-fold versus unshaded plants.
Key terms
- Agrivoltaics
- Using the same land for both solar energy generation and agriculture.
- photovoltaic cells
- An electronic device that converts light directly into electricity via the photovoltaic effect.
- photosynthesis
- The biological process by which plants and other organisms convert light energy into chemical energy.
