Credentials That Actually Matter

When a salesperson drops acronyms, it should simplify trust, not cloud it. We demystify NABCEP certifications, state contractor and electrical licenses, manufacturer training badges, and insurance proofs, explaining what each covers, how to verify authenticity, and where corners often get cut.

01

NABCEP, State Licenses, and Electrical Scope

Ask for the specific credential numbers and verify them on official registries. NABCEP Board Certified PV Installation Professional indicates rigorous experience, while a state electrical or C-46/Solar license defines legal scope. Confirm the qualifier actually oversees your project, not a rented license holder.

02

Manufacturer Training and Approved Networks

Panels, inverters, and batteries often require trained installers for extended warranties and firmware access. Ask for current training certificates and presence on manufacturer locators. Approved network status can lift service priority and reduce downtime, especially for hybrid inverters and battery commissioning procedures.

03

Insurance, Bonding, and Permitting Readiness

Request certificates of insurance naming you as additionally insured, with adequate general liability and workers’ compensation. Bonding adds protection on larger jobs. Confirm the installer pulls permits under their own license and understands your AHJ’s plan check, fire setbacks, and inspection expectations.

Warranties Without Surprises

Great gear still needs promises that perform. Learn to separate product, performance, and workmanship warranties, decode exclusions around roof penetrations, understand transferability when selling your home, and map the actual claims path so support arrives swiftly when something fails or underproduces.

Spotting Red Flags Early

High-Pressure Sales and Unrealistic Savings

If a representative insists the price expires today or guarantees your bill will be zero year-round, pause. Reliable installers model utility rates, seasons, and shade. Ask for assumptions in writing and require at least three days to review every proposal calmly.

Opaque Change Orders and Missing Paper Trails

Unexpected adders for trenching, service upgrades, or roof repairs appear when surveys are sloppy. One reader in Phoenix saw a last-minute $2,800 trenching charge because measurements were guessed. Demand site photos, measurements, and signed change orders before work proceeds, preventing budget shocks.

No Physical Presence, Sparse References, Vanishing Act Risks

A website alone is not enough. Check for a real office, service fleet, and inventory access. Call references from at least two years ago and recent months. Consistent satisfaction across time reduces the risk of startups that disappear after installation.

Reading Proposals Like an Expert

A strong proposal shows transparent equipment choices, modeled production with weather data, shading analysis, roof layout, and a clear construction timeline. We break down each element, explain what normal ranges look like, and show how apples-to-apples comparisons reveal genuine value differences.

Contracts and Financing Choices

The paperwork should protect both sides. We explain the differences between cash, secured and unsecured loans, leases, and PPAs; reveal fine-print pitfalls like escalators and UCC filings; and show how to negotiate fair terms, performance assurances, and cancellation rights without friction.

Quality Installation and Safety Practices

A beautiful system begins with meticulous construction. We highlight roof protection, structural considerations, wiring craftsmanship, rapid shutdown compliance, labeling, and commissioning. Expect a detailed walkthrough you can bring to the site, plus tips for cordial communication with inspectors and neighbors.
