When evaluating land for a utility-scale solar project, a battery storage facility, or a data center campus, the due diligence process can be slow, expensive, and fragmented. LandGate's Property Report consolidates the critical signals (land value, topography, solar resource, and electrical infrastructure) into a single document that lets developers quickly screen sites before committing to deeper feasibility work.
This post walks through each section of a LandGate Property Report, explaining what data is provided and why it matters at each stage of a development decision.
Instantly Access Nationwide Property Data via LLM
LandGate’s comprehensive property data is available nationwide and fully optimized for AI. Using our Model Context Protocol (MCP) Server, you can pipe this granular site-selection data directly into your LLMs (like ChatGPT, Claude, or internal tools) to automatically generate custom reports, programmatically build developer dashboards, and analyze thousands of parcels in seconds.
Starting Point: The Summary
The summary page is designed to surface a go/no-go read in under a minute. It presents the total acreage, parcel count, and aggregate land value alongside the figure developers care most about at the screening stage: the estimated solar farm lease value in dollars per acre per year.
This figure is calculated using LandGate's engineered valuation model, which incorporates local irradiance, land characteristics, topographic constraints, and comparable market transactions. It serves as a credible starting anchor for lease negotiations. It is not a certified appraisal, but it is a defensible, data-driven estimate.
The summary also flags scores and estimates for battery storage suitability, EV charging potential, and water value. For sites where these readings are populated, they can open up co-location or alternative revenue conversations early in the process.
Land Cover and Environmental Conditions
The land section breaks the property into cover types (woodland, shrubland, grassland, cropland, developed) with acreage and associated value for each. For developers, this breakdown does two things: it gives a quick read on environmental complexity, and it flags conditions that may affect permitting or operations.
Key metrics included in this section:
Cropland irrigation percentage:Â Active agricultural operations can complicate solar leases and may trigger additional county or state review processes.
Relative water stress index:Â A critical input for data center developers evaluating cooling feasibility, and less consequential for solar PV, which requires minimal water after construction.
Annual precipitation and temperature range:Â Relevant for structural loading, panel performance modeling, and site access planning.
Average annual wind speed:Â Useful context for wind resource screening and climate load assumptions in structural design.
Together, these data points let a developer identify environmental red flags such as high water stress, significant wetland coverage, or active cropland before spending money on site visits or third-party studies.
Topography: Does the Land Actually Pencil?
Slope is one of the most decisive factors in solar development economics. Steeper terrain means higher grading costs, more complex racking systems, and reduced panel efficiency due to tracking limitations. LandGate's topography section provides:
Average and maximum elevation
Average and maximum slope in degrees
An average slope below 5° is generally preferred for utility-scale ground-mount solar to keep civil costs manageable. Sites with a high maximum slope warrant attention even if the average is acceptable, since those areas may be economically unviable for installation and need to be excluded from buildable acreage calculations. The elevation range across a parcel also informs civil engineering decisions and access road design.
Solar Resource and Buildable Acreage
This section delivers the most direct value for solar developers. It moves beyond raw irradiance to answer the question that actually determines project size and economics: how many of these acres can realistically be developed?
Resource Quality
LandGate reports both 2D and 3D solar irradiance figures. The 3D figure accounts for terrain orientation and is a more accurate input for energy yield modeling than flat-plane irradiance. Sites in the southwestern United States, for example, routinely show strong 3D irradiance numbers that support viable PPAs, and this data gives developers the ability to compare resource quality across candidate sites with a consistent methodology.
Buildable Acreage
Gross acreage is rarely the right input for project sizing. LandGate filters the gross footprint through a series of constraints to arrive at a buildable figure:
Topographic exclusions at multiple slope thresholds (5%, 8%, 12%, 15%)
Wetland exclusions
Transmission line buffer zones
Tree canopy coverage
This layered analysis is critical for pro forma accuracy. A developer who simply assumes gross acreage is deployable will overstate project capacity and understate cost per MW, errors that can invalidate financial models and create problems at the offtake negotiation stage.
Capacity and Output Estimates
Based on the buildable acreage, the report projects the possible number of solar panels, maximum system capacity in MW, and maximum annual output in MWh. These figures provide an initial basis for revenue modeling before a full energy yield study is commissioned, and they give a quick sanity check on whether a site is sized appropriately for the developer's target capacity range.
Electrical Infrastructure: The Make-or-Break Section
Access to grid interconnection is the single largest variable in determining whether a site can be permitted and financed. LandGate's electrical infrastructure section gives developers an immediate read on interconnection viability without requiring a utility data request or an interconnection consultant at the screening stage.
Transmission Line Access
The report identifies the nearest transmission line, its owner, its distance from the property, and its rated capacity. Distance to transmission is one of the clearest cost signals in early-stage site screening. New transmission line construction typically runs $1–3 million per mile and can add years to a development timeline. A site with a high-capacity line already on or adjacent to the property is fundamentally different from one that requires miles of new infrastructure.
Substation Proximity
Substation name and distance are provided. Hosting capacity (how much additional load or generation the substation can absorb) is populated where data is available. This figure is increasingly important as grid congestion grows, and when it is present in the report it can save significant time that would otherwise be spent on utility information requests.
Nearby Generation
The report identifies the nearest operating solar farm and wind farm, including operator, distance, and capacity. Proximity to existing generation is meaningful for several reasons: it confirms prior interconnection has been approved in the area, validates the resource quality in the local environment, and signals familiarity in the permitting and utility regulatory landscape.
What This Report Tells You — and What It Doesn't
A LandGate Property Report is a screening tool, not a substitute for full feasibility work. Here's how each section maps to the decisions it supports:
Report Section | Decision It Supports |
Summary / Lease Estimate | Lease negotiation anchor; acquisition budgeting |
Land Cover & Water Stress | Environmental risk flagging; data center water feasibility |
Topography | Civil cost estimation; tracker vs. fixed-mount decision |
Solar Resource + Buildable Acreage | Preliminary capacity and output modeling |
Electrical Infrastructure | Go/no-go screening on interconnection viability |
What comes after a Property Report, for sites that pass screening, is a site-specific feasibility study including a Phase I environmental assessment, a transmission interconnection study, and geotechnical investigation. LandGate in partnership with KPMG can also provide certified appraisals for formal transaction purposes.
