Brazil's farmers are betting on solar energy to stabilize the power supply

According to experts and growers, Brazilian farmers are expanding their solar power capacity and testing battery storage solutions in an effort to increase electricity supply predictability and reduce diesel consumption.

The increased use of alternative energies in Brazil, which is the largest exporter of food products, will result in greater business for equipment suppliers, a reduced dependency on fossil fuels and more efficient agriculture. WEG and other companies that offer energy solutions say that the interest of farmers in battery-based systems has increased in recent months. Projects are now being implemented after a dramatic drop in battery costs. Around 14% of the solar power installed in Brazil is generated by rural properties. 4.8 gigawatts are distributed through small photovoltaics, which are often constructed on roofs or undeveloped land. According to an analysis by the Brazilian Association of Photovoltaic Solar Energy, solar capacity in agriculture has increased more than sevenfold since 2020 when renewable energy projects began booming across the country. According to the association, the number of rural consumers using solar panels has risen from 54,000 in 2014 to 471,000 at the end of 2024. Solar power is used by Brazilian farmers for irrigation of crops, air conditioning, lighting, pumping up water in reservoirs, and powering cold-storage rooms. Batteries can also be used to reduce diesel consumption in farms where generators run on the fuel power irrigation and agricultural equipment on farms that are not connected to the grid. Farm group Bom Futuro in Mato Grosso invests in energy generation and is currently evaluating the use of batteries to reduce power outages.

Livio Costa is Bom Futuro’s manager of Energy. He said that interruptions in electricity supply disrupt cotton machines and production causing material loss.

He said that if the power went out for 15 minutes it could take two hours before production resumed. This doesn't happen just once. "It happens several times during harvest." Bom Futuro’s investments in energy generation reflect an increased demand on farms for grain drying, storage and cotton processing that is power intensive.
