SB 1419: solar energy; inspection; contractors - Arizona

Senate Engrossed Version (03/02/2026) → Chaptered Version · 5 edits

MODERATE

This bill was finalized into law after passing the House, with significant substantive changes to Arizona's solar energy regulations. The most critical update redefines 'solar energy devices' to strictly exclude utility-scale projects and systems designed for off-site use, limiting the law's protections to residential and multifamily structures only. Additionally, the bill introduces new requirements for contractors to evaluate roof structural integrity before installation and mandates specific disclosures regarding system maintenance costs and warranty terms for consumers.

Scope change

The scope of the bill was narrowed to apply only to residential and multifamily structures, explicitly excluding commercial, industrial, institutional, and utility-scale solar projects from its provisions.

DEFINITION

The definition of 'solar energy device' was modified to exclude utility-scale solar projects and systems designed primarily for off-site loads, restricting the bill's application to on-site residential and multifamily use.

REQUIREMENT

New requirements were added mandating that licensed contractors evaluate roof structural integrity before installation and recommend professional roofing inspections to customers.

New disclosure requirements were added to contracts, specifically notifying consumers about whether system maintenance and repairs are included in the agreement and the estimated costs they are responsible for.

The contractor's liability for roof damage was modified to clarify that contractors are responsible for repairs caused by their installation, but the buyer may be responsible for future roof repairs unrelated to installation errors.

New provisions require agreements to include a brief description of the basis for any savings estimates, including utility rates, rate increase assumptions, and system production estimates.

MODERATE

The bill was amended to broaden the definition of covered energy systems to include passive solar devices like Trombe walls. It significantly strengthened contractor liability by removing exemptions for shade structures and requiring a formal evaluation of roof structural integrity before installation. Additionally, the bill updated disclosure requirements to mandate the substantiation of financial estimates and clarified warranty transfer rules.

Scope change

The scope of the bill was expanded to include passive solar energy devices (e.g., Trombe walls) in addition to active distributed energy generation systems.

DEFINITION

The definition of 'distributed energy generation system' was updated to explicitly include passive systems designed as solar energy devices, such as Trombe walls, rather than just active systems.

REQUIREMENT

Contractors installing solar on roofs must now evaluate and verify the structural integrity of the roof before installation, replacing the previous requirement to only recommend a separate inspection.

The exemption for shade structures (used for vehicles or livestock) was removed, meaning contractors are now liable for roof damage on these structures as well.

Disclosures regarding utility rate estimates must now include a substantiation of the methodology used to calculate the estimates.

The requirement for contractors to obtain a written acknowledgment from buyers regarding roof damage liability was clarified to include an exception if the registrar of contractors determines the damage was caused by the contractor.

MODERATE

The bill was reformatted from a standard legislative introduction to a House Engrossed version, which typically indicates it has passed the House and is ready for final Senate action. The substantive legal text, including definitions, warranty requirements, and disclosure rules, remained unchanged in its core content, though some formatting and specific phrasing within the definitions were slightly adjusted.

Scope change

The scope of the bill's applicability remains focused on solar energy devices, distributed energy generation systems, and related contractors in Arizona; no new entities were added or excluded.

TECHNICAL

The document structure was updated from an 'Introduced Version' to a 'House Engrossed Version,' reflecting its progression through the legislative process.

DEFINITION

Minor wording adjustments were made to the definition of 'Solar energy device' to clarify that it is limited to systems serving on-site demand at residential or multifamily structures.

The definition of 'Trombe wall' was updated to use lowercase 'trombe wall' instead of all caps.

REQUIREMENT

The list of requirements for solar energy device installation was renumbered and slightly rephrased, though the underlying obligations (fire codes, manufacturer requirements, etc.) remained the same.

The requirement for roof evaluations before installation was clarified to explicitly state that the contractor is deemed to have accepted the roof surface for the initial installation.

The disclosure requirements for sales agreements were reorganized and renumbered, with minor text changes to ensure clarity regarding tax obligations and maintenance cost estimates.
