Quick Answer
Bifacial panels can be a good investment for small farm operations, particularly those with large open spaces and limited shading. They can increase energy production by up to 25% and provide a higher return on investment compared to traditional monofacial panels. However, the cost is higher upfront.
Bifacial Panel Benefits for Small Farms
Bifacial panels are designed to capture light from both the front and back sides of the panel, increasing energy production. This can be particularly beneficial for small farm operations with large open spaces, such as fields or pastures, where the panels can be installed facing towards the sun. Studies have shown that bifacial panels can increase energy production by up to 25% compared to traditional monofacial panels.
System Design Considerations
When designing a bifacial solar system for a small farm operation, it’s essential to consider the panel’s orientation and installation height. Research suggests that a tilt angle of 20-30° and an installation height of 2-3 meters above the ground can optimize energy production. Additionally, the use of a reflective surface, such as a white or aluminum-coated roof, can increase energy production by up to 10% for bifacial panels.
Cost and Return on Investment
While bifacial panels come with a higher upfront cost, they can provide a higher return on investment for small farm operations. According to a study by the National Renewable Energy Laboratory (NREL), bifacial panels can increase the levelized cost of electricity (LCOE) by up to 10 cents per kilowatt-hour (kWh) compared to traditional monofacial panels. However, this increase can be offset by the higher energy production and longer lifespan of bifacial panels, which can last up to 25 years or more.
