Solar Lease vs. Farming Income in Idaho
At an average rate of $523/acre/year, a 100-acre solar farm lease in Idaho generates approximately $52,300/year in guaranteed income, growing with the 2% annual escalator. Over 25 years, this totals approximately $1,845,185 for 100 acres.
By comparison, Idaho farmland (valued at approximately $3,500/acre in the West region) typically generates $200-$400/acre in net farming income, with significant variability from year to year.

Many Idaho landowners choose to lease a portion of their property for solar while continuing to farm the rest, creating a diversified income stream.
What Makes Land Suitable for Solar Farms in Idaho?

- 2Topography: Flat or gently south-facing terrain. Steep slopes and uneven ground increase construction costs and reduce developer interest.
- 3Grid Access: Within 1-2 miles of a high-voltage transmission line or substation. This is often the most critical factor for project viability in Idaho.
- 4Minimal Shading: Clear of trees, buildings, and other obstructions. Previously cleared agricultural land and pastures are ideal.

The guaranteed nature of solar lease income can also improve your ability to secure agricultural financing.
The ideal Idaho property for a solar farm lease is flat or gently south-facing, at least 20-50 acres (larger is better), free of significant tree cover or shading, and located within 1-2 miles of a high-voltage transmission line or substation.
