A solar farm profit calculator is a powerful tool that helps investors, landowners, and solar developers estimate the financial returns of a solar farm project. By inputting key details like land area, installation costs, and revenue rates, you can calculate your return on investment (ROI), annual earnings, and break-even period. Whether you’re exploring a small 1 MW farm or a large-scale project, this article and our free calculator will guide you to make informed decisions.

Key Factors That Affect Solar Farm Profitability
Several variables determine how much profit a solar farm can generate:
- Land Area & Sunlight Availability: More land and higher solar irradiance (e.g., in Texas or Arizona) boost energy production.
- Installation Cost Per Watt: Typically $0.80–$1.50/W for utility-scale projects, depending on scale and technology.
- Government Incentives: Federal Investment Tax Credit (ITC) or state-specific rebates can reduce upfront costs by 26–30%.
- PPA Rate: Rates range from $0.03–$0.10/kWh, depending on location and contract terms.
- O&M Costs: Annual maintenance (cleaning, repairs) typically costs 1–2% of initial investment.

4. How to Use the Solar Farm Profit Calculator (Step-by-Step)
- Enter Land Area: Input available land (e.g., 5 acres). Note: 1 MW typically requires 4–6 acres.
- Set System Size: Specify capacity (e.g., 1 MW or 5 MW).
- Add Cost Per Watt: Use regional averages (e.g., $1.10/W).
- Input PPA Rate: Enter the rate you’ll earn per kWh sold (e.g., $0.06/kWh).
- Include O&M Costs: Estimate annual maintenance (e.g., $20,000/MW).
- Calculate: Get instant results for revenue, profit, and break-even.
Example: For a 5-acre, 1 MW solar farm in Texas:
- Installation cost: 1 MW × $1.10/W = $1.1 million
- PPA rate: $0.06/kWh
- Annual output: ~1.5 million kWh (assuming 4.5 sun-hours/day)
- Annual revenue: 1.5M kWh × $0.06 = $90,000
- Break-even: ~12 years (after O&M and incentives)
Solar Farm Revenue Models
- Power Purchase Agreements (PPA): Long-term contracts (15–25 years) to sell energy at a fixed rate to utilities or businesses.
- Net Metering & Grid Selling: Sell excess power to the grid, often at wholesale rates (varies by state).
- Community Solar Projects: Sell subscriptions to local residents or businesses, offering stable revenue with lower upfront costs.
6. Real-Life Profitability Examples
- Case Study 1: 10-Acre Farm in Texas
- System: 2 MW, $1.00/W ($2M total cost)
- PPA Rate: $0.05/kWh
- Annual Output: ~3M kWh
- Annual Revenue: $150,000
- After O&M ($40,000/year) and 26% ITC: Break-even in ~10 years, ROI ~8% annually.
- Case Study 2: Rooftop Commercial Solar in California
- System: 500 kW, $1.20/W ($600,000 total cost)
- PPA Rate: $0.08/kWh
- Annual Output: ~800,000 kWh
- Annual Revenue: $64,000
- After O&M ($12,000/year) and incentives: Break-even in ~8 years, ROI ~10% annually.
Project Type | Size | Cost | PPA Rate | Annual Revenue | Break-Even | ROI |
---|---|---|---|---|---|---|
Texas Farm | 2 MW | $2M | $0.05 | $150,000 | ~10 years | 8% |
CA Rooftop | 500 kW | $600K | $0.08 | $64,000 | ~8 years | 10% |

How profitable is a 1 MW solar farm?
A 1 MW farm can generate $50,000–$100,000/year, depending on PPA rates and location, with ROI of 6–12% after costs.
What is a good ROI for a solar farm?
A 7–12% annual ROI is typical for utility-scale projects, factoring in incentives and O&M.
How long does it take to break even?
Most solar farms break even in 8–12 years, depending on costs, incentives, and revenue.
Do solar farms qualify for tax benefits?
Yes, the federal ITC offers a 26% tax credit (as of 2025), plus state-specific rebates in many areas.
