Quick Facts
What land lease and purchase are
For ground-mount solar projects, the land arrangement is one of the most fundamental decisions. The two main approaches are lease (long-term right to use land without ownership) and purchase (outright acquisition of land).
Each has distinct implications for capital, lender comfort, operational flexibility, and exit strategy. The right choice depends on project specifics, developer strategy, and financing structure.
In India, both arrangements are common. Lease is dominant in solar parks (where the state agency holds land), in private agreements with land owners, and in projects where capital conservation is important. Purchase is common in standalone projects, where the developer wants full control, and in projects with strong balance sheets.
Land lease structure
A typical solar land lease has:
Tenure: 25 to 30 years, matched to PPA tenure plus margin. Extension options sometimes included.
Rent: Annual or quarterly payment to land owner. Escalation clause typical (3 to 5 percent per year compound or fixed step-ups).
Lease deed: Registered document detailing rights and obligations of both parties.
Permitted use: Solar power generation and ancillary activities.
Decommissioning obligation: Developer typically must remove the plant and restore land at lease end.
Assignment rights: Conditions under which lease can be transferred.
Force majeure: Provisions for events beyond control.
Dispute resolution: Arbitration or court jurisdiction.
The lease deed is critical legal documentation that defines the relationship for two to three decades.
Land purchase structure
Land purchase involves outright acquisition:
Title verification: Comprehensive due diligence on land ownership history, encumbrances, disputes.
Sale agreement: Detailed contract specifying terms.
Registration: Stamp duty and registration charges paid to state government.
CLU (Change of Land Use): Agricultural to industrial conversion required for solar use.
Mutation: Land records updated in revenue records.
Possession: Legal handover.
After purchase, the developer is full legal owner with all rights including future sale, alternative use, or development.
Lease versus purchase trade-offs
The fundamental trade-offs:
Capital outlay:
Lease: Low upfront cost. Annual lease payments treated as operating expense.
Purchase: High upfront capital. Lower ongoing land cost (mostly property tax and maintenance).
Total cost over 25 years:
Lease: Cumulative lease payments often exceed land value. Especially with escalation.
Purchase: Initial cost; appreciation may offset.
Financing:
Lease: Lenders may require tripartite agreements and strong lease covenants.
Purchase: Simpler from financing perspective. Land becomes collateral.
Operational flexibility:
Lease: Subject to lease deed terms. Some restrictions on modifications.
Purchase: Full control. Easy to expand, modify, or repurpose.
Exit strategy:
Lease: Project sale subject to lease assignment provisions.
Purchase: Cleaner exit. Land plus plant can be sold.
Risk profile:
Lease: Counterparty risk (land owner behaviour, succession issues).
Purchase: Title risk (verified upfront).
Tax treatment:
Lease: Rent is operating expense.
Purchase: Capital expenditure. Land value typically not depreciable.
Each project’s specific circumstances should determine the choice.
Lease rate patterns
Lease rates in India vary widely:
Rajasthan, Madhya Pradesh (low-value desert/scrubland): Rs 5,000 to Rs 25,000 per acre per year.
Gujarat (better but extensive land available): Rs 15,000 to Rs 50,000 per acre per year.
Karnataka, Andhra Pradesh: Rs 20,000 to Rs 75,000 per acre per year.
Tamil Nadu, Maharashtra: Rs 30,000 to Rs 1 lakh per acre per year.
Punjab, Haryana (better agricultural land): Rs 50,000 to Rs 2 lakh per acre per year.
Escalation typically 3 to 5 percent per year. Some leases have step-ups every 5 years.
Lease rate per acre should be compared to electricity revenue per acre. Typical solar generates Rs 8 to 12 lakh per acre per year of electricity revenue. Lease cost is small fraction; affordable in most scenarios.
Solar park lease
The MNRE Solar Parks scheme provides leased land to developers:
State agency develops the solar park (land aggregation, CLU, common infrastructure).
Pre-developed plots offered to selected developers.
Lease typically 25 to 30 years matched to PPA.
Lease rate competitively set; often below market.
Common infrastructure (substation, evacuation, roads, water) provided by park developer.
For developers, solar parks offer streamlined land acquisition with reduced risk. The trade-off is location restrictions (must be in the park) and dependence on the park developer.
Lender perspective
Lenders evaluate land arrangements carefully:
Lease tenure: Should exceed PPA tenure with margin.
Lease deed terms: Strong provisions favouring developer.
Tripartite agreement: Lender, developer, land owner. Lender gets step-in rights if developer defaults.
Title verification: For purchases, clean title essential.
CLU status: Required before disbursement.
Escrow arrangements: For lease payments.
For lender-grade projects, lease arrangements need strong legal structure. Purchases typically face simpler diligence.
Common land arrangement mistakes
Insufficient lease tenure. Short leases create lender problems.
Weak lease deed. Inadequate protection for developer and lender.
Skipping title verification. Pre-existing claims or disputes can derail projects.
Inadequate CLU planning. Required for both lease and purchase.
Underestimating land owner relationships. Long-term cooperation essential.
Ignoring decommissioning obligation. Lease-end costs should be planned.
Missing local approvals. Gram panchayat NOCs often required.
Best practices
For lease arrangements:
Engage experienced land lawyers familiar with state-specific issues.
Negotiate strong protections in lease deed.
Build relationships with land owners and local community.
Plan for decommissioning costs.
For land purchase:
Comprehensive title due diligence.
Consider land aggregator services for multiple parcels.
Plan for CLU process.
Document land transactions thoroughly.
For lender relationships:
Use tripartite agreements for lease.
Maintain documentation supporting land arrangements.
Address lender concerns about land arrangements proactively.
For exit planning:
Consider land arrangement implications for future sale.
Maintain land arrangement compliance throughout project life.
Standards and references
Land arrangements are governed by state-specific land laws, lease deed templates, registration acts, and revenue codes. CLU requirements vary by state. MNRE solar park guidelines specify lease arrangements for park-based projects. Lender’s diligence frameworks address land arrangement requirements.

Key takeaways
Land for ground-mount solar projects can be either leased (typically 25 to 30 years matched to PPA tenure) or purchased outright. Lease reduces upfront CAPEX but creates long-term obligation; purchase requires higher CAPEX but provides full ownership and simpler financing. Lease rates in India range from Rs 5,000 to Rs 2 lakh per acre per year depending on state and land quality. The choice depends on project scale, capital availability, financing structure, lender requirements, and exit strategy. Solar parks under MNRE provide leased land with developed infrastructure as a third option.
