Benefits of Installing Solar Panels for Farms

Solar panels can help farms reduce purchased electricity, improve energy independence, make productive use of barn roofs or available land, and support long-term sustainability goals. Depending on the system design, they may also power irrigation, pumps, refrigeration, ventilation, lighting, and other agricultural loads.

1.Lower Electricity Costs

Solar panels can significantly reduce your electricity bills.

Many farmers report savings of thousands of dollars per year by generating their own electricity.

2. Greater Energy Independence

If you generate your own electricity, you reduce your dependence on the power grid.

This is particularly important at times of peak consumption when energy costs can soar.

Solar panels put you in control of your energy production.

3. Sustainable Farm Operations

Using solar energy helps to reduce your carbon footprint.

It is a clean, renewable energy source that helps to preserve the environment.

Adopting solar technology can support broader sustainable farming practices.

4. Productive Use of Roof and Land

Installing solar panels can make productive use of suitable farm buildings, roofs, or available land.

Barn-mounted systems can use existing roof space, while ground-mounted systems can be designed around available land, site conditions, access requirements, and future farm use.

5. Potential Financial Incentives

Eligible farm solar projects may qualify for federal, state, utility, USDA, or other incentive programs, depending on location and current program requirements.

Eligible incentives may reduce the net cost of a solar project, but availability, eligibility, and funding requirements vary by program.

How Much Can Solar Panels Save a Farm

There is no single savings figure for every farm. Annual savings depend on electricity use, utility rates, daytime load, system size, solar resources, self-consumption, export rules, financing, incentives, maintenance, and battery storage.

Estimated Annual Savings = Solar Electricity Used On-Site × Utility Electricity Rate + Export Compensation − Annual System Costs

For example, if a farm uses 300,000 kWh/year, with solar offsetting 150,000 kWh on-site at $0.12/kWh, the theoretical value of avoided electricity purchases is:

150,000 × $0.12 = $18,000/year

This is a demonstration calculation only, not a project-specific savings estimate. It excludes financing, maintenance, export compensation, incentives, and other costs. Actual savings should be calculated using the farm's electricity use, solar production, utility rates, and applicable grid rules.

Types of Solar Panels for Agricultural Use

When considering solar panels for farms, it's essential to know which types are available. Here are some common options:

1. Monofacial Solar Panels

These panels capture sunlight from one side and are typically used in traditional installations.

They are efficient and widely available, making them a popular choice among farmers.

2. Bifacial Solar Panels

Bifacial solar panels capture sunlight from both sides, increasing energy production.

They are particularly effective in environments with reflective surfaces, such as snow or sand.

3. Thin-Film Solar Panels

These lightweight panels are flexible and can be integrated into various surfaces, including building materials.

While they may have lower efficiency compared to crystalline options, they can be advantageous in certain applications.

4. Agrivoltaic Systems

Agrivoltaics combines solar power generation with agricultural activities on the same land. Depending on the system design, solar panels can be installed above or between crops and grazing areas, allowing solar generation and farming to share the same space. USDA Climate Hubs agrivoltaics guidance

Barn-Mounted vs Ground-Mounted Solar for Farms

Farm solar systems can be installed on suitable agricultural buildings or available land. Barn-mounted systems make use of existing roof space without using additional farmland, while ground-mounted systems provide more flexibility in system size, orientation, and layout.

Barn-mounted systems require a suitable roof with adequate structural condition, space, and solar exposure. Ground-mounted systems require suitable land and should account for soil conditions, drainage, farm machinery, and maintenance access.

The choice depends on roof condition, available land, shading, access, electricity needs, and future farm use. U.S. Department of Energy Farmer's Guide to Going Solar

How Much Land Do Solar Panels for Farms Require?

One common concern is space—how much land will you need for solar panels for farms?

• Roof-Mounted Systems: If you have suitable buildings like barns or silos, roof-mounted solar panels require no additional land at all.

• Ground-Mounted Systems: The land needed depends on the size of the system.

Considerations:

• Assess available space on your farm.

• Determine how much electricity you want to generate.

• Consult with a solar provider to evaluate your specific needs.

What Is Agrivoltaics?

Agrivoltaics combines solar power generation with agricultural activities on the same land. Depending on the system design, solar panels can be installed above or between crops and grazing areas, allowing solar generation and farming to share the same space. USDA Climate Hubs agrivoltaics guidance

Crops

Agrivoltaic systems can support certain crops grown beneath or between solar panels. The partial shade from the panels may help reduce heat exposure and slow moisture loss in some growing conditions, which can potentially reduce irrigation needs. However, the effects vary by crop type, climate, panel height, spacing, and system design.

Crop selection should consider sunlight requirements, local growing conditions, panel configuration, and access for planting, harvesting, and other farm operations.

Livestock Grazing

Solar sites can sometimes support compatible livestock grazing, allowing agricultural production and solar generation to share the same land. Proper panel height, spacing, fencing, livestock access, and equipment clearance should be considered when designing a grazing-compatible solar system.

Water and Shade

Solar panels can provide partial shade that changes the amount of sunlight and heat reaching crops and soil. In some agricultural settings, this may help reduce heat stress and retain soil moisture, potentially lowering irrigation needs.

Solar power can also support farm water and irrigation systems. For example, electricity generated by a solar system can be used to operate irrigation pumps and other water-related equipment, while battery storage can provide energy when solar production is lower.

The actual benefits depend on crop type, climate, seasonal conditions, panel design, and site layout.

Limitations

Agrivoltaic projects require careful planning to balance solar generation with agricultural productivity. Crop compatibility, panel height and spacing, machinery access, irrigation, drainage, maintenance, local regulations, and long-term farm use should all be evaluated before installation.

Farmers should also consider whether solar panels could affect planting, harvesting, livestock movement, or the operation of agricultural equipment. Agrivoltaic systems should be designed around the farm's existing operations rather than treated as a one-size-fits-all solution.

What Should Farmers Consider Before Installing Solar?

Before installing solar panels, farmers should evaluate both their energy needs and the conditions of the installation site.

Electricity Consumption

Review annual and daytime electricity use to determine an appropriate solar system size and understand how much solar energy the farm may use directly.

Roof or Land Suitability

Check roof condition, available space, shading, orientation, soil conditions, and site access to determine whether the location is suitable for solar installation.

Interconnection

Confirm grid connection requirements and applicable export or net-metering rules with the local utility before installing a grid-connected solar system.

Soil and Drainage

For ground-mounted systems, evaluate soil conditions, drainage, erosion risks, and potential impacts on agricultural productivity.

Farm Machinery

Make sure the solar layout does not interfere with tractors, irrigation equipment, livestock movement, maintenance access, or other farm operations.

Future Land Use

Consider planned farm expansion, new buildings, crop changes, equipment needs, and other long-term land-use plans before selecting the system location.

Solar Incentives and Financing for U.S. Farms

Solar projects for U.S. farms may have access to federal tax incentives, USDA programs, loans, power purchase agreements (PPAs), and state or utility programs. Eligibility and funding requirements vary and can change over time, so farmers should verify current rules before including incentives or financing benefits in a project cost or payback calculation.

Federal Tax Incentives

Eligible farm solar projects may qualify for federal clean-energy tax incentives under current tax rules. For qualifying clean electricity facilities and energy storage technology placed in service after December 31, 2024, the Section 48E Clean Electricity Investment Credit generally starts at a 6% base rate and may increase when applicable requirements are met. IRS Clean Electricity Investment Credit

Because federal tax rules and eligibility requirements can change, farm owners should review current IRS guidance and consult a qualified tax professional before including a tax credit in project financial calculations.
