Every part of the project creates a different conversation.

Roof condition. Electrical capacity. Equipment. Design changes. Permits. Utility approval. Interconnection. Customer expectations. Delays. Additional work. Commissioning. Final payment.

Your contract should already understand those conversations before the job starts.

California + Solar

State-Specific Law Is Only Half The Job.

California residential solar sits inside a detailed home-improvement framework and also carries solar-specific disclosure requirements. But knowing the statute does not tell you what happens when the roof is different from the survey, equipment changes, the utility takes longer than expected or a customer thinks something was included that was never in the price.

CALIFORNIA REQUIREMENTS

Built around the state.

The California edition addresses the contract structure, notices, payment framework, changes, cancellation information and solar-specific requirements relevant to residential contractor paperwork.

SOLAR INSTALLATION

Built around the trade.

The paperwork follows the project from scope and equipment through site conditions, installation, approvals, commissioning and handover.

DISPUTE POINTS

Built around what goes wrong.

We identify the grey areas that commonly become arguments — then build clearer expectations and a professional process around them.

Built for contractors who want paperwork that understands the job. Clear enough to use, detailed enough to understand the project, and structured around the issues that matter.
The Work Behind The Contract

How A California Solar Contract Gets Built.

The finished document is designed to be straightforward. Building it is not. We combine trade knowledge, dispute knowledge, state-specific research and attorney input before it becomes the contract a customer sees.

PROJECT MAPPING

Start with the entire install.

We map the job from survey and specification through roof and electrical conditions, design, permitting, equipment, installation, inspection, utility processes, commissioning and handover.

DISPUTE MAPPING

Ask where it can go wrong.

What if the roof needs work? What if electrical upgrades appear? What if equipment changes? What if approvals move the schedule? What if the customer remembers the scope differently? Those are contract questions.

CALIFORNIA LAYER

Build around the state rules.

We review the California requirements that affect the agreement, including home-improvement contract content, payment rules, cancellation information, notices and solar-specific disclosure obligations.

TRADE TERMS

Turn experience into terms.

The solar issues are organized into clear project provisions covering scope, equipment, conditions, changes, approvals, timing, completion, warranties and payment.

ATTORNEY REFINEMENT

Strengthen the framework.

Attorney knowledge refines the practical contractor input and the state-specific structure so the document works as a professional agreement rather than a collection of legal phrases.

ONGOING REVIEW

California does not stand still.

Relevant changes are reviewed against the California edition. Your purchase includes access to the updates we make during the included 18-month update period.

Inside The California Edition

Professional Paperwork That Looks Like It Belongs To A Professional Contractor.

Customers do not need a lecture in contract law. They need to understand the project they are agreeing to. The California edition is designed to organize the important information clearly while keeping the detailed protection where it belongs inside the agreement.

You fill in the project. The trade-specific and state-specific framework is already there.

A Contract That Knows Solar

From The First Survey To The Final Handover.

The point is not to cram the agreement with every legal phrase we can find. It is to understand the project deeply enough to know what needs to be clear.

Survey & Existing Conditions

Roof condition, access, mounting areas, existing electrical equipment and site limitations can affect the work once installation begins.

System Design & Equipment

Panels, inverters, batteries where included, electrical equipment, system specification and customer selections all shape what has actually been sold.

Permits & Inspection

Plans, AHJ requirements, permitting and inspections can affect sequence and timing outside the physical installation itself.

Utility & Interconnection

Utility review, interconnection and permission-to-operate processes can continue beyond installation and involve third-party timing.

Changes & Additional Work

Roof repairs, service upgrades, design revisions, customer changes and concealed conditions can change scope, price or schedule.

Performance & Expectations

Generation, savings and utility-bill expectations can become major misunderstandings if the agreed system and representations are not clear.

Delays & Dependencies

Equipment availability, weather, inspections, utilities and customer decisions can all affect when a solar project reaches the next stage.

Commissioning & Completion

Testing, system startup, final checks, documentation and completion need a clear point in the project process.

Payment & Handover

Professional payment stages, approved changes, completion expectations and handover paperwork help keep the final invoice from becoming the first time the parties discuss the rules.

Where Solar Disputes Begin

We Build Around The Conversation You Do Not Want To Have Later.

What HappensWhere The Disagreement StartsWhat Clear Paperwork Does
The roof or electrical system needs additional work.“I thought that was included.”Records the agreed scope and provides a professional route for additional work and changes.
Equipment, permitting, inspection or utility timing moves.“You said it would be finished by then.”Sets clearer expectations around project timing and external dependencies.
The customer expects a different system outcome.“That is not what I thought I was buying.”Creates a clearer written record of system specification and agreed project information.
The customer asks for something different mid-project.“It is only a small change.”Gives both sides a professional change process before the work and price move.
Final payment becomes due.Old assumptions suddenly become payment objections.Establishes payment, completion and change expectations before the final invoice arrives.
A contract cannot guarantee that nobody will ever disagree. What it can do is remove grey areas, record expectations and give the project a professional process before the disagreement begins.

California-Specific Means California-Specific

California Has Rules A National Form Can Miss.

California's home-improvement framework includes detailed requirements around written agreements, payments, change orders, cancellation information and consumer notices. Residential solar also has its own disclosure requirements.

For example, California generally requires a written home-improvement contract once the project is over $500. The ordinary home-improvement down payment is generally capped at $1,000 or 10% of the contract price, whichever is less, subject to statutory exceptions. Covered residential solar transactions also require a specific solar disclosure document presented in 16-point bold type.

Those details are why California gets a dedicated California edition built around the state's requirements.

$500+

General California written home-improvement contract threshold.

$1,000

General down-payment ceiling, or 10% of the contract price if less, subject to statutory exceptions.

16pt

Bold type required for California's solar disclosure document for covered residential transactions.

Official California Documents

Your Contract Is Part Of The Paperwork — Not A Replacement For Government Forms.

Where California requires an official solar disclosure or consumer document, the current government-issued document should be used. We do not rewrite an official form, put our logo on it and pretend it is ours.

The Construction Companion agreement does a different job: it creates the contractor-customer framework around the actual project, including the scope, price, changes, project conditions, timing, completion and the solar-specific areas contractors need addressed.

Official disclosure where required. Professional project agreement alongside it.

Contractor Written. Attorney Refined.

Trade Knowledge First. Legal Knowledge Where It Matters.

We know why a contractor cares about an existing roof, a service upgrade, equipment availability, a utility delay, a customer change and the final invoice. Those are not abstract legal topics. They are the points where real jobs become difficult.

Attorney knowledge strengthens that contractor-led foundation and the state-specific framework. The aim is not to make the document sound more legal. The aim is to make it more useful.

Clear terms. Real solar knowledge. California-specific structure. No unnecessary legal theatre.

California Solar Contract FAQ

Straight Answers Before You Buy.

Why do I need a California-specific solar contract?

California has detailed home-improvement requirements and additional residential solar disclosure requirements. A state-specific edition lets the agreement be built around those requirements as well as the practical solar project.

Does the contract understand actual solar installation issues?

That is the point. The agreement is built around the full project rather than only generic payment and liability wording — including scope, equipment, roof and electrical conditions, changes, approvals, delays, commissioning, completion, warranties and payment.

Is it full of legal jargon?

No. We use legal structure where it matters, but the goal is a professional contractor agreement that can actually be understood and used. If a clause does not help define the project, manage a real risk or meet a legal requirement, adding complexity for appearance's sake is not the objective.

Does it replace California's official solar disclosure documents?

No. Current government-issued documents should be used wherever California requires them. Your Construction Companion contract is the project agreement that sits alongside required official paperwork.

Which contract should I choose?

Working directly for a homeowner? Choose Residential Solar and select California. Contracting on a commercial project for a business or commercial owner? Choose Commercial Solar and select California.

Can I reuse the contract?

Yes, for suitable future projects. Your purchase includes editable Word and PDF documents, unlimited downloads during the 18-month access period and free updates for 18 months. There is no subscription.

Built On Current Requirements

California Changes. Your Paperwork Should Not Stand Still.

The California edition is reviewed against relevant changes to contractor and solar requirements. When we update the edition during your included 18-month period, the updated version is available as part of your access.

One purchase. 18 months of updates. No subscription. Your California edition is maintained as relevant requirements change.

Important: This guide and our contract templates are not legal advice and do not create an attorney-client relationship. Requirements can depend on the transaction, financing, sales method and project circumstances. Contractors remain responsible for licensing and compliance and should use current official government forms where required.
