USDA REAP covers 25-50% of project cost as a grant. Section 48E adds 30-70% ITC. Stack them together and New England farms can go solar for pennies on the dollar.
Section 48E deadline: construction must begin before July 4, 2026
New England farms can install solar for as little as 10-25% of the total cost by stacking USDA REAP grants (25-50% of project) with Section 48E ITC (30-70% base + bonuses) and state incentives. REAP applications open annually in March/April. Section 48E requires construction to begin before July 4, 2026. A 100 kW system that costs $250,000 gross can net out to $85,000-$100,000 after all incentives — paying for itself in 3-4 years.
Agriculture is energy-intensive — dairy cooling, greenhouse heating, irrigation pumping, and grain drying can cost $2,000-$10,000/month in electricity. New England farms have the infrastructure, land, and incentive stack to make solar one of the best investments available.
Barns, equipment sheds, and livestock buildings provide 2,000-10,000+ sq ft of south-facing roof space — often unshaded and structurally suitable for solar.
Marginal pasture, buffers, and setback areas are ideal for ground-mount arrays. Many farms have 1-5 acres of underutilized land perfect for solar.
New England farms pay $0.20-$0.32/kWh — 40-80% higher than the national average. Dairy cooling, ventilation, and grain drying alone can exceed $3,000-$8,000/month.
MA SMART agricultural adder, VT net metering, ME NEB credits, and RI REG payments stack on top of federal programs for massive cost reductions.
Farm-to-table consumers value sustainability. Solar-powered farms earn premium pricing, CSA loyalty, and agritourism interest.
Rural power grids are vulnerable to ice storms and outages. Solar + battery gives farms uninterrupted power for livestock ventilation, refrigeration, and milking operations.
Energy use varies dramatically by operation. Solar system sizing should match your actual utility bills — NuWatt analyzes 12-24 months of data for accurate projections.

NuWatt has experience preparing winning REAP applications and provides the complete technical documentation package.
The residential solar tax credit (Section 25D) expired December 31, 2025. But farms are commercial entities — they qualify for Section 48E, the commercial investment tax credit, which is still very much alive.
Construction must begin before July 4, 2026. This means either starting physical work of a significant nature (breaking ground, installing racking) or meeting the 5% safe harbor rule (paying at least 5% of total project cost). NuWatt can help you meet the safe harbor deadline with a deposit and equipment order.

View PA solar guideFarm solar is not one-size-fits-all. The right approach depends on your buildings, land, energy needs, and whether you want to continue farming under the panels.
Most common, lowest cost
South-facing barn roofs are ideal — large, unshaded, and structurally designed for snow loads. Most farms start here. NuWatt verifies structural capacity and installs engineered racking systems rated for 50 lb/sq ft snow loads.
Best for larger systems (50-500+ kW)
Marginal pasture, buffer zones, and setback areas that cannot be farmed or developed are perfect for ground-mount arrays. Fixed-tilt or single-axis tracking. Driven pile or ballasted foundations depending on soil.
Crops + solar — NuWatt specialty
Elevated solar panels (8-12 ft) allow continued farming underneath. Shade-tolerant crops like lettuce, herbs, berries, and mushrooms thrive. Some crops see 10-30% yield improvement from reduced heat stress. Premium SMART agricultural adders in MA.
Remote barns, irrigation pumps, fencing
Remote farm buildings, irrigation pumps, and electric fencing often lack grid connections. Solar + battery eliminates the need for expensive utility extensions ($15,000-$50,000) or diesel generators. Payback under 3 years for remote applications.
NuWatt specializes in agrivoltaic (dual-use) installations — solar + continued farming.
Read our NJ agrivoltaics case studyREAP is competitive. These six steps will strengthen your application and maximize your chances of winning the grant.
REAP applications score higher when you document current energy consumption with utility bills (12-24 months) and an energy audit showing reduction potential. NuWatt provides NABCEP-certified energy assessments.
Show USDA the financial impact: current energy costs, projected savings, payback period, and how solar supports farm viability. Include cash flow projections for 10-20 years.
Each NE state has a USDA Rural Development office. Request a pre-application review and letter of support. This demonstrates commitment and can improve your score.
Show how you will cover the non-REAP portion. Section 48E ITC, state incentives, and farm operating budget all count. The more funding sources, the stronger your application.
REAP has limited annual funding. Applications submitted early in the March-April window get reviewed first. Do not wait until the deadline — start preparation in January.
NuWatt prepares the technical package: system design, production estimates, equipment specifications, and interconnection plans. Our REAP-experienced team has a strong approval track record.
USDA REAP (Rural Energy for America Program) provides grants covering 25-50% of renewable energy project costs for agricultural producers and rural small businesses. To qualify, you must be an agricultural producer (any size — from hobby farms to large operations) or a rural small business in an eligible area. Most New England farmland qualifies as rural. You do not need to be a full-time farmer — part-time agricultural operations, including CSAs, orchards, maple sugar operations, and livestock farms, are eligible.
Yes. USDA REAP grants and Section 48E ITC are fully stackable. However, the ITC is calculated on the net cost AFTER the REAP grant is subtracted. For example, a $250,000 system with a $62,500 REAP grant would have a 48E ITC calculated on $187,500 (not the full $250,000). You can also stack state incentives, MACRS depreciation, and utility rebates on top of both federal programs.
Farm solar in New England costs $2.20-$3.50 per watt ($2,200-$3,500 per kW) before incentives, depending on installation type. Barn rooftop is cheapest at $2.20-$2.80/W. Ground mount runs $2.40-$3.00/W. Agrivoltaics (dual-use) costs $2.80-$3.50/W due to elevated racking. After stacking REAP + 48E + state incentives, net cost drops to $0.50-$1.25/W — a 60-80% reduction from gross cost.
Yes. Section 48E is the commercial/investment tax credit that replaced Section 48. It is available for farm solar installations that begin construction before July 4, 2026. Farms are commercial entities, so they qualify for the commercial ITC — unlike residential homeowners who lost the Section 25D credit when it expired December 31, 2025. The base ITC is 30%, with potential bonuses up to 70% for domestic content, energy community, and low-income qualifications.
Construction must BEGIN before July 4, 2026. "Begin construction" means either starting physical work of a significant nature (breaking ground, installing racking) or meeting the 5% safe harbor rule (paying at least 5% of total project cost). NuWatt can help you meet the safe harbor deadline with a deposit and equipment order even if installation happens later in 2026.
You do not need to own the land outright. Long-term lease agreements (typically 10+ years) qualify for REAP, provided you have the landowner's written permission and the lease term covers the useful life of the solar system. However, you must be the agricultural producer operating on the property. Absentee landowners who lease farmland to tenants cannot apply — the farming tenant would need to apply.
Absolutely. Farm solar can offset any electrical load on the property. Dairy farms typically use 4,000-12,000 kWh/month for cooling, milking, and ventilation. Greenhouses use 3,000-15,000 kWh/month for heating/cooling and grow lights. Irrigation pumping uses 2,000-8,000 kWh/month during growing season. Solar is particularly cost-effective for these high-consumption operations because the payback period is shorter when annual savings are higher.
Ground-mount solar requires approximately 5-7 acres per MW (1,000 kW) of capacity. For a typical 100 kW farm system producing ~130,000 kWh/year, you need about 0.5-0.7 acres. Most farms start with barn rooftop solar (zero additional land), then expand to ground mount on marginal land. Agrivoltaic (dual-use) systems allow continued farming underneath elevated panels, so there is no true land loss — just partial shade that benefits many crop types.
NuWatt will analyze your farm's energy use, design an optimal solar system, and prepare your USDA REAP application package — all at no cost until you decide to proceed.
