Farm Solar Calculator Canada
Estimate system size, install cost, federal Clean Technology ITC (30% refundable), and payback for a barn rooftop or ground-mount solar project on your Canadian farm. Free — no signup required.
Farm solar estimate
Enter your farm type, consumption, and site details. The tool will estimate system size, cost, federal Clean Tech ITC value, and payback specific to agricultural operations.
Estimates are for planning purposes only. Real project economics depend on site conditions, utility interconnection, and equipment selection. Get a professional quote for site-specific numbers.
Enter your consumption details on the left and click Calculate estimate to see project size, cost, incentives, and payback.
How each farm type sizes differently
Farm solar sizing depends more on load shape than on total electricity use. A dairy at 90,000 kWh/year and an irrigation-heavy operation at 120,000 kWh/year end up with very different system recommendations because their consumption timing matches solar production differently.
Refrigeration, ventilation, and milking loads run 24/7 — strong pairing with battery or heavy net export.
Ventilation and lighting create steady daytime demand — solar routinely covers 40–70% of annual use.
Seasonal load peaks during harvest — sizing should reflect grain drying and yard equipment demand.
Supplemental lighting and climate control drive very high loads — often the biggest ROI category on farm.
Mixed operations often combine barn rooftop and yard ground-mount to reach target sizing.
Pumping loads peak during solar production hours — strong solar-load match, especially in the Prairies.
Steady arena and stable loads with lower seasonality — pairs well with a modest rooftop array.
Four steps to a farm solar estimate
Dairy, poultry, greenhouse, crop, mixed, irrigation, or equestrian — each has a different load shape that changes system sizing and payback.
Enter your monthly bill or annual kWh. If you don't know exact numbers, the calculator uses typical usage benchmarks for the selected farm type.
Add barn roof area for rooftop, yard area for ground-mount, or set 'either' to let the calculator size around your load first.

What the farm calculator uses
- check_circleProvince irradiance data. Annual kWh per kW installed and peak sun hours per province — Saskatchewan and Alberta produce the most per installed kW in Canada.
- check_circleFarm-type load coincidence. How much of solar production your operation can actually consume on-site (higher = higher effective savings rate).
- check_circle2026 farm cost benchmarks. $1.90–$2.70 per installed watt for rooftop or ground-mount farm solar, blended.
- check_circleFederal Clean Technology ITC. Up to 30% refundable on eligible clean-technology property. Applied to ~90% of install cost as ITC-eligible.
- check_circleBattery pricing benchmark. ~$1,300/kWh installed for Canadian commercial LFP packs when battery storage is enabled.
- check_circleNet-metering / net-billing rates. Blended retail + export rate reflects how much of solar production is self-consumed vs exported at each province's rate.
Estimates are for planning purposes. Farm-specific projects should factor in three-phase service, demand charges, seasonal load patterns, and current AAFC ACT program status. Request a professional quote for site-specific numbers.

How accurate is the farm solar calculator?add
The calculator gives a planning-grade estimate accurate to ±15% for most Canadian farm sites. It uses province-level irradiance (kWh/kW/year), farm-type load coincidence factors, 2026 Canadian farm solar cost benchmarks ($1.90–$2.70/W installed), and the federal Clean Technology ITC framework (up to 30% refundable). Real quotes will vary based on site-specific structural work, three-phase service, utility interconnection scope, and equipment tier.
What farm types work best for solar in Canada?add
Greenhouse and dairy operations sit at the top of the list — both run high, steady, daytime loads that solar can offset efficiently. Poultry, irrigation, and mixed operations follow. Crop farms tend to see more seasonal load peaks around harvest and drying, so sizing needs to reflect grain drying and yard equipment demand. See our full farm solar hub for a load-profile breakdown by farm type.
Does the calculator include the Agricultural Clean Technology Program (ACT)?add
The calculator surfaces the ACT program alongside the federal Clean Tech ITC in your results, but doesn't apply ACT amounts to the payback math because AAFC ACT funding is cost-shared and application-based rather than a flat rate. When ACT support is approved for your project, it further reduces net cost beyond what the calculator shows.
Rooftop barn solar or ground-mount — which will the calculator recommend?add
The calculator uses your selected mount preference (rooftop, ground, or either) plus the usable area you enter. When area is limiting, the tool caps the system at ~10 W per usable sq ft (industry planning rule) and suggests expanding to ground-mount to unlock more capacity. Most Canadian farms combine both — barn rooftop as the base array, ground-mount for expansion.
How does the calculator handle three-phase service and demand charges?add
The current version uses annual kWh and effective retail rate for its payback math and doesn't separately model demand charges or three-phase upgrade cost. Farms with heavy pump loads, milking parlors, greenhouse lighting, or irrigation systems on general-service commercial rates should share their demand-charge history and any three-phase constraints with quoting installers for a site-specific proposal.
How much does farm solar cost in Canada in 2026?add
Farm solar in Canada typically runs $1.90 to $2.70 per installed watt in 2026, depending on rooftop vs ground-mount, project size, and site complexity. A 100 kW barn rooftop system on a mixed farm usually lands in the $190,000–$250,000 range before federal Clean Tech ITC (up to 30%), AAFC ACT support, and any applicable provincial programs.
Can the calculator estimate battery storage for my farm?add
Yes. Toggle 'Include battery storage' and the calculator will add roughly 30 kWh of storage at the 2026 Canadian commercial-pack benchmark (~$1,300/kWh installed). Battery pairs especially well with dairy operations, greenhouse lighting, and any farm with 24/7 base loads or high demand charges. For sites needing backup power during grid outages, mention that during quoting so installers can specify appropriate battery capacity.
