Agrivoltaics
Ginger and turmeric from your spice rack could soon be grown under solar panels, meaning the food you cook with and the clean energy powering homes can come from the exact same patch of land.
Researchers in Bangladesh tested what happens when you grow crops in the shade of solar panels instead of choosing between farming and solar energy. Spices like ginger and turmeric actually grew better under the panels than in open fields, while winter vegetables like tomatoes and onions produced a bit less. The approach also opened up new income opportunities for women farmers in the region.
Key Findings
Ginger and turmeric yields increased by 12.3% and 8.7% respectively when grown under solar panels compared to open-field plots.
Seven winter crops including tomato, onion, and garlic saw yield reductions of 10–20% under shaded conditions.
Scaling the pilot to Bangladesh's ~45 ha of solar irrigation pump sites could yield nearly 594 tonnes of ginger and turmeric worth approximately US$0.56 million per season.

Growing shade-tolerant crops like ginger and turmeric beneath solar panels in rural Bangladesh boosted yields by up to 12%, while also generating renewable energy — showing that farmland and solar power don't have to compete for space.
Abstract Preview
The growing demand for food, energy, and water in resource-constrained regions intensifies land-use conflicts, where solar photovoltaic (PV) expansion often competes with agriculture. Agrivoltaics,...
