Assessing Your Agricultural Building for Solar Suitability

Agricultural Building Solar

Not all barns or agricultural buildings are created equal when it comes to solar potential. Here’s what our 8MSolar experts consider in a thorough assessment:

1. Structural Integrity

The integrity of the building’s structure is paramount. Roofs must be in good condition and capable of supporting the additional weight of solar panels, which typically adds about 2-4 pounds per square foot. For older structures, this may necessitate repairs or reinforcements before installation.

A comprehensive structural assessment should consider:

  • The age and condition of the roof
  • The load-bearing capacity of the structure, including trusses and purlins
  • The expected lifespan of the roof in relation to the 25-30 year lifespan of solar panels

2. Orientation and Shading

The orientation of the building and potential shading issues play crucial roles in system efficiency. In the Northern Hemisphere, south-facing roofs are ideal, but east and west-facing roofs can also be suitable. A detailed shading analysis should be conducted, taking into account:

  • Seasonal changes in sun angle
  • Potential obstructions like nearby trees or structures
  • Seasonal variations in vegetation that might affect shading

3. Available Roof Space

The usable area for solar panel installation needs to be carefully calculated. This assessment should consider:

  • Total available roof space
  • Setbacks required for fire safety and maintenance access
  • Roof features like vents, chimneys, or skylights that may limit panel placement

4. Electrical Infrastructure

The existing electrical setup of the farm needs to be evaluated to ensure it can accommodate the new solar system. This includes:

  • Assessing the current electrical panel capacity
  • Evaluating the condition and capacity of existing wiring
  • Determining the proximity to the main electrical panel, which can affect installation complexity and cost

Types of Solar Installations for Agricultural Buildings

At 8MSolar, we tailor our solar solutions to meet the unique needs of each agricultural property. Here’s a detailed look at the options:

1. Roof-Mounted Systems

Traditional fixed panels directly attached to the roof structure are a popular choice for many farms. These systems are ideal for pitched roofs with good southern exposure. For flat or low-slope roofs, ballasted systems that don’t require roof penetrations can be an excellent option, minimizing the potential for leaks.

2. Ground-Mounted Arrays

When roof space is limited or unsuitable, ground-mounted systems offer a flexible alternative. These can be oriented and tilted for optimal sun exposure and allow for easy access for maintenance and cleaning. Solar trackers, which follow the sun’s movement throughout the day, can increase energy production by up to 25% compared to fixed systems.

3. Integrated Systems

For farms concerned about aesthetics or historical preservation, integrated systems like solar shingles can blend seamlessly with traditional roofing materials. Thin-film solar, which can be applied directly to metal roofing, offers a lightweight and flexible option for roofs with weight restrictions.

4. Dual-Use Installations

Agrivoltaic systems that combine solar panels with crop production or grazing areas underneath represent an innovative approach to land use. These systems can increase overall land productivity by up to 70%. Examples include raised panels over vegetable crops or integrating panels with berry production.

5. Carport and Equipment Shed Systems

Solar panels can be incorporated into the design of carports and equipment sheds, providing both energy generation and covered storage for farm vehicles and machinery. This dual-purpose approach maximizes the utility of farm structures.

Overcoming Challenges in Agricultural Solar Installations

Installing solar on agricultural buildings can present unique challenges. Here’s how we at 8MSolar address them:

  1. Dust and Debris:

Dust and debris accumulation can significantly impact panel efficiency. Regular cleaning schedules tailored to the farm’s specific conditions are essential. In high-dust areas, automated cleaning systems or special coatings that repel dust may be warranted.

  1. Animal Interference:

For buildings housing livestock, protective measures must be implemented to prevent animal damage. This might include reinforced lower panels, protective fencing, or raised systems designed to allow animals to pass underneath safely.

  1. Remote Locations:

Many farms are located in areas with weak or unreliable grid connections. Off-grid solutions and battery storage systems can enhance energy reliability for critical farm operations. For some operations, implementing a microgrid might be the most effective solution to ensure consistent power availability.

  1. Seasonal Usage:

Agricultural energy needs often vary significantly with the seasons. Solar systems for farms should be designed with this variability in mind, potentially incorporating energy storage solutions or flexible grid integration to manage seasonal fluctuations in energy production and consumption.

  1. Weather Extremes:

Agricultural solar installations must be designed to withstand local weather conditions. This might include reinforced mounting systems for high-wind areas, steeper panel tilts for regions with heavy snowfall, and comprehensive lightning protection for all installations.
