BUILT FOR COMMERCIAL SOLAR CONTRACTORS

Commercial Solar Project Experience & Legal Expertise Combined

Built For The Way Commercial Solar Projects Are Actually Delivered.

A professional commercial solar contract template for U.S. solar contractors working directly with businesses and commercial property owners. Built around the language, stages and administration of real commercial solar projects, then strengthened with attorney knowledge.

Commercial solar is managed through defined project stages. Design and submittals lead into approvals, procurement, construction, commissioning, interconnection and formal handover. Your agreement should be able to follow that same project from the commercial proposal through completion.

COMMERCIAL SOLAR INSTALLATION CONTRACT TEMPLATE

BUILT FOR U.S. COMMERCIAL SOLAR CONTRACTORS

A comprehensive Commercial Solar Installation Contract Template developed specifically for solar contractors carrying out PV installations for businesses, commercial property owners and other commercial clients across the United States.

From the nation's trusted construction contract store, this agreement combines real construction experience, commercial solar knowledge and attorney expertise to create clear professional terms from the initial scope, design and system specification through installation, commissioning, closeout and final payment.

Built around the realities of commercial solar installation — and the way contractors actually deliver these projects.

BUILT FOR COMMERCIAL SOLAR. NOT JUST CONSTRUCTION.

Commercial PV projects have their own moving parts.

The system may be installed across a commercial rooftop, on the ground or as part of a solar carport or canopy. Engineering and design requirements can develop as the project moves forward. Existing roof, structural and electrical conditions can affect the installation. The property may remain operational throughout the work. Utilities, inspectors, engineers, roofers, other trades and client representatives may all form part of the wider project.

Your contract should understand that too.

This template is built around commercial solar work while retaining the wider contractual structure needed for a professional commercial construction project.

FROM DESIGN & ENGINEERING TO COMMERCIAL CLOSEOUT

Commercial Scope & System Specification
Clearly establish the PV system being supplied and installed, the agreed work, project requirements, equipment and relevant exclusions.

Design, Engineering & Project Documentation
Provide a framework around project design, engineering requirements, plans, specifications and revisions so the agreement can follow the project as technical requirements are developed and confirmed.

Rooftop, Ground-Mount & Carport Installations
A framework capable of being used across different commercial PV projects rather than assuming every solar installation is the same.

Roof, Structural & Mounting Conditions
Commercial rooftop projects can involve structural requirements, attachment methods, penetrations and coordination with existing roof systems, roofing contractors or manufacturer requirements. The agreement gives these project conditions a proper place within the commercial scope.

Site Access, Safety Requirements & Business Operations
Set out project access, working restrictions and site requirements where installation takes place at an operating commercial property, including coordination with client representatives and other trades where applicable.

Existing Site & Electrical Conditions
Deal clearly with the conditions the contractor is pricing against and provide a process when the installation identifies additional requirements or work outside the original agreed scope.

Electrical Infrastructure & Additional Works
Commercial solar can involve more than modules and racking. The agreement provides a structure for dealing with electrical infrastructure and additional works identified as the project develops.

Utility Interconnection, Permits & Approvals
Establish responsibilities surrounding applications, information, coordination, inspections and approvals while recognizing that utility and authority-controlled processes can affect the wider project schedule.

Equipment, Procurement & Substitutions
Clearly document the equipment forming part of the contract while providing a contractual process where specified products become unavailable, procurement conditions change or an agreed substitution becomes necessary.

Schedule, Milestones & Project Delays
Give the commercial project a clearer structure around commencement, agreed milestones, installation progress and completion while providing a framework for events that can affect the project schedule.

Changes & Additional Work
When the commercial client changes the specification or additional work becomes necessary, there is a clear route for documenting the change and adjusting the contract price and/or schedule.

Progress Payments & Commercial Invoicing
Built around commercial contracting, with provisions for the agreed contract price, payment stages, invoices, additional work and final payment.

Testing, Commissioning & System Handover
Physical installation isn't necessarily the end of a commercial solar project. The agreement provides a framework for testing, commissioning and handover.

Punch List, Closeout & Project Documentation
Give completion a proper commercial process, with a framework for outstanding items and agreed project closeout documentation such as applicable as-built information, commissioning records, equipment information, warranty documentation and operation or maintenance information required by the project.

COMMERCIAL SOLAR EXPECTATIONS — PUT INTO WRITING

Commercial clients can look at a solar project in terms of more than the physical installation. Production expectations, financial assumptions, incentives, utility programs and other project benefits may form part of the wider commercial decision.

The contract gives the parties a place to define what has actually been agreed rather than leaving important expectations to assumptions, sales conversations or documents that were never intended to form the construction agreement.

WORKMANSHIP AND EQUIPMENT WARRANTIES — CLEARLY SEPARATED

A contractor's workmanship and a manufacturer's warranty on modules, inverters, racking and other equipment are not the same thing.

The agreement is structured to distinguish the contractor's workmanship obligations from applicable manufacturer and product warranties, helping both parties understand the warranty structure surrounding the completed installation.

MORE THAN BOILERPLATE

The solar-specific provisions sit inside a wider commercial construction agreement.

That means the contract goes beyond panels and inverters to deal with the things that keep an actual commercial project organized: defined scope, contract price, authorized representatives, site access, scheduling, milestones, changes, additional work, delays, subcontractors, payment, completion, warranties, suspension, termination, disputes, insurance, notices and signatures.

Commercial projects can also involve matters such as retainage, lien-related documentation, indemnity, insurance requirements and final-payment conditions. Where these matters are applicable, the state-specific agreement structure is designed to address the commercial project within the requirements of the selected edition rather than pretending one national form fits every project in every state.

It understands commercial solar. It understands construction. And it understands that a contract has to work on a real job — not just look impressive on paper.

STATE-SPECIFIC. NOT ONE GENERIC 50-STATE CONTRACT.

Construction contract requirements are not identical across the United States.

Choose the state where the project is taking place and receive the appropriate state-specific edition, developed around the commercial solar framework and adjusted for applicable state requirements.

You choose your state. We give you the right edition.

You already know how to install solar.

Our job is to help put a professional agreement around the work you do.

Construction Companion combines contractor experience, commercial solar knowledge and attorney input to produce contracts that are straightforward enough to use on real projects while providing the professional structure expected when working with commercial clients.

WHY COMMERCIAL-SPECIFIC PAPERWORK MATTERS

Commercial Solar Deserves Commercial Project Paperwork.

A commercial solar project moves through technical design, commercial approvals, procurement, site coordination, construction, commissioning, interconnection and handover. The agreement should speak the same language as the project team using it.

COMMERCIAL SOLAR CONTRACT FAQ

Built For Business-To-Business Solar Projects.

Straight answers about the commercial solar EPC / installation agreement, what type of project it is intended for and the commercial solar language built around it.

The Agreement

Is this specifically a commercial solar contract template?

Yes. It is designed for solar contractors entering into direct contracts with businesses and commercial property owners for owner-funded commercial photovoltaic projects. It is built around commercial project administration rather than a residential homeowner sales process.

Who is the agreement for?

It is aimed at independent solar contractors, EPC contractors and growing solar businesses delivering commercial photovoltaic projects directly for business customers in the United States.

Is this a B2B agreement?

Yes. The contracting customer is a business or commercial entity rather than a residential homeowner. The paperwork is structured around commercial project responsibilities, authorized representatives, approvals, milestones, changes, completion and handover.

Is this a Power Purchase Agreement or solar lease?

No. This product is intended for contractor-to-business design and installation projects where the customer is purchasing the commercial solar work. A PPA, lease or other third-party ownership arrangement uses a different commercial and legal structure and should not be treated as the same agreement.

Can it be used for rooftop, ground-mount or solar carport projects?

The agreement is designed as reusable commercial project paperwork. The specific array type, mounting system, system size, equipment, site conditions, design documents and Description of Work are completed for each project, so the commercial framework can be adapted to different project types where appropriate.

Can I reuse it for future commercial customers?

Yes. Personalize the template for your business, complete the project-specific details for each customer and use it again on future commercial solar projects.

Commercial Solar Project Administration

What does EPC mean in commercial solar?

EPC refers to Engineering, Procurement and Construction. Commercial solar projects often combine design responsibilities, equipment procurement and physical construction within one coordinated project delivery structure. The agreement is built with that project language in mind.

What is a Notice to Proceed?

A Notice to Proceed, often shortened to NTP, is a formal project trigger used to authorize commencement of an agreed phase or the work. The template is designed so commencement can be tied to defined project conditions rather than an accidental unconditional start-date promise.

Can the agreement identify kW DC and kW AC system size?

Yes. Commercial solar paperwork should be able to identify the project and system technically, including relevant DC and AC system capacity, equipment schedules, plans, specifications and other project documents where they form part of the agreed scope.

How are AHJ approvals and utility interconnection treated?

The project framework recognizes that local authorities, inspectors and utilities can have their own review and approval processes. AHJ approvals, inspections, interconnection steps and Permission to Operate can be addressed as project requirements without pretending every external approval is controlled by the contractor.

What is the difference between Substantial Completion and Final Completion?

Commercial projects can use more than one completion milestone. Substantial Completion may identify the stage at which the agreed system is materially complete for its intended purpose, subject to remaining close-out items, while Final Completion follows completion of the remaining contractual requirements. The project should define the milestones actually being used.

Does it deal with commissioning and acceptance testing?

Yes. The commercial framework recognizes commissioning, testing and project acceptance as distinct close-out activities where they are part of the agreed scope. The exact technical procedures remain project-specific and should follow the approved design, manufacturer requirements and applicable standards.

Can payment be linked to project milestones?

Yes. Commercial solar projects are often paid through defined project stages rather than a simple residential-style deposit and balance. The agreement is built to support a clear commercial payment schedule tied to the milestones selected for the project.

What about planned electrical shutdowns and site access?

Commercial customers may have operating hours, tenants, production, security procedures or facilities teams that affect when work can take place. The agreement is built with access, coordination, work windows and planned shutdown requirements in mind where they apply to the project.

What if the approved design or equipment changes?

Commercial solar projects can change because of engineering, supply availability, utility requirements, field conditions or customer decisions. The document set includes a Commercial Solar Change Order Form so approved changes can be recorded formally rather than left to informal conversations.

What about long-lead equipment and procurement?

Commercial solar can involve modules, inverters, switchgear, transformers, racking and other equipment with procurement lead times. The project framework allows procurement and material availability to be treated as part of project administration and scheduling rather than assuming every component is immediately available.

Does it cover as-built drawings and O&M handover documentation?

The commercial framework recognizes formal project close-out and handover. As-built information, commissioning records, warranties and operation and maintenance documentation can be identified as required handover deliverables where they are included in the project scope.

Does this replace engineering, code or utility requirements?

No. The agreement provides the commercial and contractual framework for the project. It does not replace engineering documents, technical specifications, electrical codes, manufacturer instructions, AHJ requirements, utility interconnection rules or other project-specific technical obligations.

Professional Project Control

Does the agreement support authorized project representatives?

Yes. Commercial projects often involve owners, facilities teams, project managers and site personnel. Identifying authorized representatives helps make clear who can approve changes, give project instructions and receive formal notices.

Does the package include a Change Order Form?

Yes. A Commercial Solar Change Order Form is included so agreed changes to scope, design, equipment, price or project time can be recorded professionally.

What is the Project Completion & Handover Certificate for?

It gives the contractor a professional close-out document for recording completion and the handover of the agreed project information or documents. It supports a cleaner transition from construction and commissioning into project close-out.

Why not just use a residential solar contract?

Because the commercial customer, project administration and delivery language are different. B2B projects can involve authorized representatives, formal submittals, milestone payments, business-site coordination, NTP, commissioning, multiple completion stages and structured handover.

Who developed the contract?

Construction Companion combines real contractor and commercial solar project knowledge with attorney expertise. The aim is professional paperwork that makes sense both to the company delivering the work and the business customer signing it.

BUILT FROM COMMERCIAL SOLAR PROJECT EXPERIENCE

From NTP To Project Handover. The Paperwork Should Follow The Project.

Commercial solar has defined stages, technical documents, stakeholders, approvals and completion requirements. This agreement is built to provide one clear commercial framework through those stages rather than forcing a business project into residential-style paperwork.

B2B PROJECTS NEED B2B ADMINISTRATION

Professional project control creates a better customer experience.

Clear representatives, documented scope, milestone payments, formal changes, completion stages and handover requirements help both parties understand how the project will be administered from the beginning.

WHO WE'RE BUILDING FOR

NOT THE BIG CORPORATIONS.

Large EPC companies can have in-house counsel, contract managers and entire project administration teams. Independent and growing commercial solar contractors still need paperwork that looks at home on serious projects. That is who we build for.

Commercial solar has its own language and project flow. EPC scope, NTP, submittals, utility coordination, milestone payments, commissioning, completion stages and handover belong in the conversation from the start.
