Solar Power for Farms

Solar power offers farms and homesteads a path to energy independence. With falling prices and generous incentives, now is an excellent time to consider going solar.

Benefits for Farms

Lower energy costs: Lock in electricity rates for 25+ years
Energy independence: Less vulnerability to grid outages
Income potential: Sell excess power back to grid
Tax benefits: Federal and state incentives
Property value: Solar increases farm value
Environmental: Reduce carbon footprint

System Types

Grid-Tied Systems

Connected to utility grid
Net metering credits for excess power
No batteries needed (grid is backup)
Most cost-effective option
Goes offline during grid outages

Hybrid (Grid-Tied with Battery)

Grid-connected plus battery backup
Power during outages for critical loads
Higher cost but more security
Good for areas with unreliable power

Off-Grid Systems

Completely independent of utility
Requires significant battery bank
Higher upfront cost
Total energy independence
Best for remote properties

☀️ Start With Efficiency

Before installing solar, reduce your energy use! LED lighting, efficient appliances, and insulation improvements make your solar system smaller and cheaper. Every watt saved is a watt you don't need to generate.

Sizing Your System

Step 1: Analyze Usage

Review 12 months of electric bills
Calculate average monthly kWh
Consider future needs (electric vehicle, shop tools)

Step 2: Calculate System Size

Rough calculation: Annual kWh ÷ 1,200 = system size in kW (varies by location)

Example: 12,000 kWh/year ÷ 1,200 = 10 kW system

Step 3: Space Requirements

Approximately 100 sq ft per 1 kW of panels
10 kW system = ~1,000 sq ft of roof or ground space
South-facing preferred (east/west acceptable)

Farm Solar Applications

Barn and shop power: Lights, tools, ventilation
Water pumping: Solar-powered well pumps
Electric fencing: Solar fence chargers
Refrigeration: Walk-in coolers, freezers
Irrigation: Solar pumps for drip systems
Greenhouses: Heating and ventilation

Costs and Incentives

Typical Costs (2024)

Grid-tied: $2.50-3.50 per watt installed
10 kW system: $25,000-35,000 before incentives
After 30% federal tax credit: $17,500-24,500

Financial Incentives

Federal ITC: 30% tax credit through 2032
USDA REAP: Grants up to 50% for rural farms
State incentives: Vary by location
Accelerated depreciation: For farm businesses

Ground vs. Roof Mount

Roof Mount

No land use
Usually cheaper to install
Roof must be in good condition

Ground Mount

Easier access for cleaning/maintenance
Optimal positioning possible
Uses some land area
Can graze sheep beneath panels!

Getting Started

Reduce energy usage first
Get multiple quotes (at least 3)
Check installer credentials and reviews
Understand your utility's net metering policy
Research available incentives
Consider financing options (loans, leases, PPAs)
