Smart Greenhouses Set to Slash Electricity Costs

A team of University of Georgia researchers designed ground-breaking new lighting system that could reduce a farmer’s electrical bill. The new system could work around reducing the electrical demand without hurting the plants. Electrical engineering master’s student Shirin Afazli worked on building a control system that uses sensors. The sensors can further measure current weather conditions, and Ph.D. student Sahand Mosharafian and associate professor Javad Mohammadpour Velni helped develop light-predicting algorithms in their laboratories. The system is said to predict the amount of sunlight in the future. Thus, it can help to optimize the lights inside the greenhouse, plus give plants the correct amount of light.

The research work, recently published in Plants, reiterated (based on the data) that farmers could reduce their greenhouse electrical costs by as much as 33% by optimizing their lights.

In the backdrop that greenhouses are typically used during the winter and spring, the team tested their system during both growing seasons. When conducting the experiments, both showed reduced costs while maintaining plant growth.

However, the new system was observed to have made more significant impact during the spring. It reduced costs by 33% in the spring and 4% in the winter. Furthermore, the system generates the most savings while the sun is shining. With the winter months having shorter days, the lights are typically
required to be switched on more often.

Marc Van Iersel, a professor in the College of Agricultural and Environmental Sciences, stated that when LED lights first came to market, they gave an opportunity to control greenhouse lighting on a level that was not possible before. He added that at the time, a lot of research was happening to optimize the lights themselves, but almost no one was working on smart control of the lighting system.

The electricity used for the lights is anywhere to the tune from 10% to 30% of the cost of running a greenhouse. Thus, the research began with the idea that if the cost could be reduced further, there could be an impact on the efficiency and sustainability of greenhouses.

According to the researcher team, the actual cost savings could be even greater. Though their experiments assumed a fixed cost for electricity, farms are usually subject to variable pricing in the real world. The team has already accounted for this variable and plans to work on and publish future research underscoring higher savings rates.
