Off-Grid Solar Installers for Cochise County: Who Actually Does It

Search "solar installer Sierra Vista" and you get a page of Tucson companies selling grid-tied rooftop arrays with a financing agreement attached. That is a different product from what a parcel outside Pearce or McNeal needs. Off-grid is batteries, a charge controller, a generator input, a well pump that has to run at noon, and nobody from the utility to call when it trips.

Fewer firms do that work than advertise it. Here are the ones we could verify from their own websites, followed by what Arizona law says any of them owes you on paper, and what you give up if you build it yourself.

The firms

The Solar Store, Tucson

At 2833 N. Country Club Rd. in Tucson, The Solar Store says it has been in business since 1998 and lists Cochise County alongside Pima, Pinal and Santa Cruz counties as service areas. Its menu is the broadest of the three for a rural property: off-grid solar photovoltaics, solar water pumping, solar generators and batteries, hybrid systems, plus electrical and plumbing. Its off-grid page is written for the situation here, a rural location where running power lines is expensive, and describes the system as modules, charge controller, battery bank and inverter.

Two things from its own site. It says there is a nominal charge for off-grid estimates, typically half applied to the final purchase, even though the same site invites free estimates for its standard products. And it publishes its ROC numbers in the footer, which is the right behaviour; check them anyway. Phone as published: 520-341-2286.

Cochise Tech, Hereford

A different kind of company, and that matters for what to expect. Its site describes a commercial general contractor that started in 2007 as a small electrical company and works mainly on Fort Huachuca. Its renewable energy page offers design-build solutions for off-grid and grid-tie solar with an in-house design team, and says it has installed systems from small residential to large commercial. The project it describes in most detail is over 130 modular training units on Fort Huachuca, each with its own hybrid inverter and battery backup.

Its licensing page lists a CR-11 electrical classification (the dual commercial and residential electrical licence) and a B-1 commercial general classification. That is a strong electrical credential for a battery-inverter system. Whether a one-house job is the size of work it wants is a question to ask directly. Mailing address is a PO box in Hereford; phone as published: 520-366-5697.

Stronghold Solar, Sierra Vista

The one firm we found with a Cochise County street address: 4661 N. Commerce Drive, Sierra Vista. Its site describes residential and commercial solar projects and says it has been an installer "for more than 8 years", though the page carries a 2019 copyright so that figure is dated. The site does not mention off-grid, batteries or ground mounts. It is here because it is local and verifiable, not because it has claimed the off-grid work; ask before assuming. Phone as published: 520.226.8260.

What Arizona law requires of the installer

A.R.S. § 44-1762 applies to every solar energy device sold or installed in the state, and most buyers have never heard of it. Its core requirements:

• A warranty. Collectors, heat exchangers, storage units and their installation warranted for at least two years, or an energy production output guarantee. Everything else, and its installation, at least one year.
• A written statement of warranty terms, responsibilities assumed or disclaimed, and performance data, on a form the Registrar of Contractors approves and keeps on public file.
• A certificate of compliance from the seller.
• A licensed solar contractor doing the installation, holding the appropriate contractor's licence.
• Installation to code: local fire, safety and building codes, consumer protection requirements, and other applicable law.

Contractors who fall short are subject to ROC discipline. If a quote arrives with no warranty statement and no certificate, you are entitled to both before you sign.

What changed in 2026

Laws 2026, Chapter 175 (SB1419), approved 19 June 2026, amended §§ 44-1761, 44-1762 and 44-1763. For an installer:

• Residential scope. "Solar energy device" is now limited to a system serving on-site demand at a residential dwelling unit or multifamily structure, and excludes utility-scale projects, systems on commercial, industrial or institutional structures, and systems serving an off-site load. A home system on your parcel is squarely inside.
• Manufacturer's instructions are now law. Installations must comply with local building codes and with the manufacturer's installation requirements, in addition to fire and safety codes.
• Roof evaluation. Before installing on a roof, a licensed contractor must evaluate whether the roof can support the system, recommend an inspection by a licensed roofing contractor, and repair damage the installation causes. Structures used primarily for shade, including for vehicles or livestock, are excluded, which covers many ground-mount and carport arrays out here.
• Bold, initialled disclosures in the agreement under § 44-1763: warranty periods for the system, major components and labor; total cost, interest, fees and payments; a lifetime maintenance cost summary; and a bold all-capitals warning that rates and incentives can change. Major components means panels, inverters, racking and battery storage. We have a separate walk through the 2026 amendments.

If you are installing it yourself

Many off-grid systems in this county are owner-built, and the law anticipates it. § 44-1762 subsection F says devices designed or installed by the final owner are exempt from subsections A through E: the two-year warranty, the written statement, the certificate of compliance, the standards subsection, and the licensed-contractor requirement. Nobody owes you a warranty on your own work.

Read what the exemption does not reach. The installation subsection, requiring compliance with local fire, safety and building codes and the manufacturer's installation requirements, is not in the exempt list. Cochise County has adopted the 2023 National Electrical Code. Under the owner-builder opt-out's Option 1 the county still inspects electrical; under Option 2 it inspects nothing, and its page says the owner-builder is fully responsible for meeting code. See what the opt-out waives.

Contractor licensing is a separate statute. A.R.S. § 32-1121(A)(5) lets an owner build on their own property, themselves or with their own employees or licensed contractors, where the structure is for the owner's sole occupancy and not for sale or rent; selling or renting within a year of completion is prima facie evidence otherwise. The ROC's rule of thumb is that a licence is required when labor and materials exceed $1,000 or a permit is required. So the exemption covers you doing your own wiring. It does not cover paying an unlicensed friend $3,000 to do it; that is his problem under § 32-1121 and yours when the inverter fails.

What we could not confirm

Stronghold Solar's site does not say whether it does off-grid or battery work. Cochise Tech's site does not define a residential service area or say whether it takes single-dwelling off-grid jobs. None of the three publishes off-grid prices, so none appear here. We found no other installer based in Willcox, Benson, Bisbee or Douglas that we could verify from its own site; if you run one, tell us.

We did not reproduce any firm's ROC licence number, because a number's status cannot be verified from a website. Check it yourself at azroc.my.site.com; it takes a minute.

If you want a quote without the ringing round, tell us the parcel and the job and a licensed local contractor will call you to quote it.
