Sanlúcar la Mayor’s economy is largely driven by agriculture, with olive oil and citrus fruits being its most notable products. The town is surrounded by vast olive groves, and its olive oil is renowned for its high quality, often produced by traditional methods that have been passed down through generations. Additionally, orange and lemon cultivation also plays a significant role in the local economy, with citrus products exported across Spain and beyond.
In recent years, the town has also embraced renewable energy, particularly solar power. Sanlúcar la Mayor is home to the PS10 Solar Power Plant, the first commercial solar tower in the world, making it a symbol of sustainable energy efforts in the region. Tourism, especially cultural and eco-tourism, has grown significantly, contributing to the local economy by attracting visitors interested in history, nature, and regional gastronomy.
Small businesses, including artisan shops and local crafts, are an important part of the town’s economic landscape. These industries not only support the local economy but also provide visitors with unique souvenirs and products that capture the essence of Andalusia.
