DER Plan Sets — Solar, Storage, Hybrid
HPH Solutions delivers storage-first, interconnection-aware plan sets for residential and small commercial Distributed Energy Resources. 1,500+ projects designed. 25+ MW. Standardized intake, repeatable outputs, built to pass.
Designed for direct-purchase, loan, and TPO systems — Sunrun, Sunnova, Tesla, GoodLeap-financed and beyond. VPP-readiness considered upstream.
We’re designed to plug into teams that have their process together.
Teams running repeatable installs who need a design partner that can match their pace—not slow them down with back-and-forth.
Companies deploying battery systems that need to stay program-compliant and VPP-ready after PTO—not just permitted.
Equipment distributors and sales organizations whose installers need design support. Wholesale and white-label programs available.
Every plan set is either PV-only (solar) or DER (solar + battery storage as one project).
You provide the house and equipment list. We do panel placement, electrical design, full layout, and permit-ready plan set.

We require complete project information before work begins: site address, photos (roof, MSP, utility meter), equipment selections, and utility/program details.
The 24-hour turnaround clock starts when we have everything we need. Incomplete submittals are returned for completion—not queued.
Email-first. All project communication runs through email for documentation, accuracy, and a clear paper trail. Emails are responded to promptly—typically within hours.
Calls are available but written communication is strongly preferred. It keeps details precise and makes it easy to reference project specifics across multiple active jobs.
Full process and terms: billing schedules, milestone breakdowns, turnaround SLAs, pass-through cost handling, and how we file under client credentials.

Who’s Behind HPH
NABCEP PV Design Specialist • ICC Permit Technician • ICC Certified Class A General Contractor
DER + VPP Design • Permit-Ready Plan Sets • Built to Scale
HPH Solutions designs solar + storage for the VPP era. Program rules, interconnection requirements, and DER architecture inform every plan set from the start—because the systems being permitted today are the same assets that will be dispatching into grid programs for the next twenty years.
The work runs on practitioner experience: NABCEP-certified design, ICC-certified permitting, and a Class A contractor’s eye for what actually gets built. Every set is accurate, complete, and tuned to the jurisdiction it’s headed to—the kind of submittal that clears review the first time.
HPH runs on standards, not size. Same intake process, same drafting conventions, same documentation rigor on every project—a model designed to stay sharp as it grows alongside the installers, EPCs, and design partners serving the VPP market.
I also track the programs, policies, and market shifts that shape how we design at vpp.services.
Deep experience with storage-first residential architectures and program-aware design.
If you’re running solar + storage installs and need a reliable design partner, send the details and let’s see if we’re a fit.
