Solar Ground Lease Calculator

Utility-scale solar projects lease farmland and open land for 25-30 year terms.

Acres leased

Per-acre rent / yr

Lease term years

Escalator %

Option period fee total

Total lease value

$11,388,600

Year 1 revenue

$300,000

Final year revenue

$570,088

How the math works

Year 1 = acres × per-acre rent. Each year escalated. Total = sum of all years.

250 × $1,200 = $300k yr 1. Year 27 at 2.5% = $575k. Total ~$12.1M + option fee.

How this calculator works

What this page estimates

This Solar Ground Lease Calculator is built to give a quick, browser-based estimate for solar ground lease. Utility-scale solar projects lease farmland and open land for 25-30 year terms. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the solar ground lease result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this solar ground lease estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions

Solar ground lease structure?

Option period (1-5 years): solar developer holds right to lease with nominal fee ($25-100/acre/year) while securing interconnection, PPA, permits. Construction period (6-18 months): higher rate ($200-500/acre). Operating period (25-30 years): base rent ($500-1,500/acre/yr) + escalator (2-3%). Some states (NY, CA, MA): $2,000-4,500/acre/yr operating rent. Rural Midwest: $800-1,800/acre.

What drives per-acre rent?

Interconnection capacity (kV availability): premium for grid access. Solar irradiance (sun hours): flat Kansas < CA desert < Arizona. PPA price environment. Land type: arable farmland typically $600-1,500/acre; marginal land $400-1,000; desert/scrubland $250-800. Revenue share structures: 5-10% of solar revenue above threshold ($1,200-2,500/acre equivalent). State incentives matter.

Lease term and renewals?

Base term: 25-30 years. Option to extend: 2-3 × 5-year renewals (bumps rent 20-40% per renewal). Total: 35-45 years possible. Panel degradation 0.4-0.8%/year means year 35 produces ~75% of year 1. Many projects repowered (new panels) at year 25-30, restart lease. Decommissioning bond ($50-150k/MW) typically required at end of life.

Landowner considerations?

Pros: steady income 25+ years, no management, property tax often reduced. Cons: land unusable (potentially farmable otherwise), aesthetic change, neighbor complaints, impact on adjacent land sale value. Net-net attractive for marginal farmland with modest agricultural profit ($100-400/acre net farm income). Solar at $1,000-2,000/acre: 5-20× farm income with zero effort.
