AHJ & Utility Database support

Every solar project must navigate a maze of local requirements—building codes, fire setbacks, electrical specifications, utility interconnection rules, and AHJ-specific documentation.

With over 30,000 unique jurisdictions in the United States, each with different requirements, keeping track is impossible without a comprehensive, continuously updated database.

At Solartro, we provide professional-grade AHJ and utility database support—giving solar installers, EPCs, and developers instant access to verified permit guidelines, jurisdiction contacts, interconnection requirements, and documentation templates that streamline approvals and eliminate costly delays.

Stop wasting hours researching individual jurisdictions. Get accurate, up-to-date requirements for any U.S. location—instantly.

We maintain a living, continuously updated database covering all 50 states, 18,000+ jurisdictions, and 3,000+ utilities—with detailed intelligence on requirements, contacts, processes, and documentation.

Freequently Asked Questions

How is AHJ & Utility Database Support different from Permit Design?

Database Support is the research foundation that informs permit design. We identify what's required; permit designers create the plans that meet those requirements. Most projects benefit from both services in sequence.

Can we use your research with another design firm?

Absolutely. Our research is comprehensive and transferable. You own all documentation and can share it with any design partner.

What if requirements change after we receive the research?

We provide ongoing monitoring and updates. If AHJ or utility standards change during your project, we alert you and provide updated guidance at no additional cost.

How long is the research valid?

Most AHJ requirements remain stable for 6-12 months. For projects taking longer, we recommend a refresh for new or updated requirements.

Do you handle special circumstances (HOA, historical districts, sensitive areas)?

Yes. Our research includes all applicable restrictions and requirements, whether local codes, HOA rules, or special overlay districts.

Can you coordinate directly with our AHJ and utility?

Yes. We handle all AHJ and utility research and coordination directly, streamlining communication and ensuring accuracy.
