Solar Easements in Colorado: Protecting Sun Access Rights

Colorado landowners who install photovoltaic or solar thermal systems face a specific legal vulnerability: neighboring structures, trees, or additions can shade panels and reduce output, with no automatic legal remedy. Solar easements are the instrument Colorado law provides to address this risk — a recorded property right that binds current and future neighbors to preserve a defined solar access corridor. This page covers how Colorado solar easements are created, what they must contain to be enforceable, the scenarios in which they appear, and the boundaries between easement coverage and other legal tools.

Definition and scope

A solar easement is a voluntary, recorded property right that prevents the owner of one parcel from obstructing sunlight to a defined area on an adjacent parcel. In Colorado, solar easements are governed by Colorado Revised Statutes § 38-32.5-100.3 through § 38-32.5-102, which establish the statutory framework for creation, recordation, and termination.

The statute defines a solar easement as any easement "for the purpose of exposure of a solar energy system to the direct rays of the sun." Unlike nuisance law or common-law light-and-air doctrines, a Colorado solar easement is an appurtenant real property interest — it runs with the land and binds successors in title automatically upon proper recording with the county clerk and recorder.

Scope limitations: Colorado's solar easement statutes apply exclusively to voluntary, negotiated agreements recorded as real property instruments. They do not create any automatic or implied right to sunlight. The statutes do not govern disputes between neighbors who lack a recorded easement, and they do not address utility-scale solar development on public lands, which falls under separate federal and state mineral and land-use frameworks. HOA solar access rules — a distinct but related topic — are covered separately at Colorado HOA Solar Rights.

Geographic coverage: This page addresses Colorado state law exclusively. Easement law in adjacent states (Wyoming, Nebraska, Kansas, New Mexico, Utah) operates under different statutory frameworks and is not covered here.

How it works

Under C.R.S. § 38-32.5-102, a valid solar easement must be created in writing and must contain, at minimum, the following elements:

1. A description of the dimensions of the easement — expressed as a vertical and horizontal angle, a shadow plane projection, or equivalent geometric description sufficient to establish the protected solar window.
2. The solar energy system to which the easement applies, identified by location on the benefited parcel.
3. Any restrictions on vegetation or construction on the burdened parcel that could obstruct the solar window.
4. The term of the easement — perpetual or time-limited, as negotiated by the parties.
5. Compensation terms, if any, paid by the benefited parcel owner to the burdened parcel owner.

Once drafted and signed by both parties, the instrument must be recorded with the county clerk and recorder in the county where the burdened property is located. Recording fees vary by county but are typically calculated per page. After recording, the easement appears in the title chain for the burdened property, providing constructive notice to any future buyer.

Enforcement proceeds through Colorado district courts. If the burdened parcel owner plants trees, erects a structure, or otherwise interferes with the protected solar window, the easement holder may seek injunctive relief and, where applicable, damages.

Understanding how a solar easement integrates with a complete installation requires familiarity with how Colorado solar energy systems work conceptually, since system placement and orientation determine which solar window angles need legal protection.

Common scenarios

New construction between established neighbors
The most common trigger is a neighbor's proposed addition, accessory dwelling unit, or new structure that would cast shade on an existing rooftop array. Without a recorded easement, the installing property owner has no legal standing to block construction that complies with local zoning. With a recorded easement specifying the protected vertical and horizontal angles, the burdened parcel owner must design around the restriction.

Planned unit developments and subdivisions
Developers of solar-ready subdivisions occasionally record solar easements in favor of each lot as part of the subdivision plat. This structure ensures that buyers in the development receive sun access protection from day one without requiring individual negotiation between neighbors.

Agricultural operations
Ground-mounted arrays on farms and ranches — addressed in more detail at Colorado Solar for Agricultural Operations — face potential shading from tree rows, grain bins, or neighboring buildings. Agricultural solar easements typically describe the shadow plane in terms of seasonal sun angles, since crop and operational structures may be repositioned over time.

Commercial and industrial parcels
Commercial installations (Commercial Solar in Colorado) may use solar easements to protect large roof or carport arrays from future development on adjacent commercial lots, particularly in areas without binding height restrictions in the local zoning code.

Contrast: solar easement vs. restrictive covenant
A solar easement and a restrictive covenant serve different functions. A solar easement is a positive real property right held by the benefited parcel — it requires the burdened parcel to refrain from obstructing a defined solar window. A restrictive covenant, common in HOA documents, is a general land use restriction that may incidentally protect solar access but is enforced by the HOA or the developer's successor, not by an individual parcel owner. Restrictive covenants cannot substitute for a recorded solar easement when direct, parcel-specific sun access protection is the objective.

The regulatory context for Colorado solar energy systems provides broader framing on the state statutes and utility rules that govern solar development in Colorado, which inform how easements interact with interconnection and permitting requirements.

Decision boundaries

Solar easements are appropriate in specific circumstances and ineffective in others. The table below identifies key decision points:

When a solar easement is the correct tool, the process involves five discrete phases:

1. Solar window analysis — Determine the exact vertical and horizontal angles that must remain unobstructed based on system orientation and local latitude. Colorado's latitude range of approximately 37°N to 41°N produces specific winter sun angles that define the critical shading corridor.
2. Survey and legal description — Engage a licensed Colorado surveyor to prepare a metes-and-bounds or angular description of the easement corridor. The Colorado Division of Real Estate (under the Department of Regulatory Agencies) licenses surveyors who can prepare legally sufficient descriptions.
3. Negotiation and drafting — The instrument must meet the statutory requirements of C.R.S. § 38-32.5-102. Both parties typically engage legal counsel at this stage. Compensation, if any, is negotiated between parties.
4. Execution and notarization — Colorado recording statutes require proper notarization of real property instruments before recording.
5. Recordation — File with the county clerk and recorder. Recording creates the public record that binds future owners of the burdened parcel.

A solar easement does not substitute for applicable permitting requirements. Rooftop and ground-mounted systems in Colorado still require building permits, electrical permits, and utility interconnection approvals regardless of whether an easement protects the installation's sun access. Permit requirements are addressed at permitting and inspection concepts for Colorado solar energy systems.
