Developer Program — Pre-Wired Solar, Storage & EV | Green Box Solar | Green Box Solar

Developer Program

Add solar, storage, and EV charging during construction to save costs, simplify schedules, and deliver homes with energy independence from day one.

Built for new construction

Pre-planning avoids costly retrofits later. We coordinate with your electrical, roofing, and schedule so trades stay moving—and homes deliver with clean, future-proof power.

  • Conduit, roof standoffs, and terminations installed at the right stage
  • Panel capacity planning for PV, batteries, and 240V EV charging
  • Clean labeling, code-compliant placement, and utility coordination
  • In-house, NABCEP-certified team—design through commissioning

Need a multi-lot or master-plan price book? We can stage conduit standards, placards, equipment schedules, and utility submittals per plan series.

Energy Storage Add-Ons

Choose whole-home or critical-load backup. Smart panels manage loads for comfort without oversizing storage. (Pre-ITC.)

Basic Backup

$12,000
  • • 14.3 kWh LiFePO₄ storage
  • • Back up to 6 home circuits
  • • Up to 4 hours peak shaving
  • • 32 A (7,600 W) off-grid power

Whole-Home Backup/Access

$18,000
  • • 28.6 kWh LiFePO₄ storage
  • • Entire home has backup access
  • • Up to 8 hours peak shaving
  • • 62.5 A (15,000 W) off-grid power
  • • Smart panel for load management/shedding

Additional Battery Module

$4,500
  • • Adds 14.3 kWh per module
  • • Extend backup/peak shaving time
  • • Priced per module
Notes: LFP (LiFePO₄) chemistry for high cycle life. We’ll confirm cold-weather placement, ventilation, and clearances during plan review.

Residential EV Chargers

Pre-plan a 240V circuit and deliver a home that’s EV-ready on day one. (Pre-ITC.)

48A Charger with Solar Integration

$1,900

Smart EVSE with PV coordination. Metering-ready, supports cleaner load profiles and owner dashboards.

48A Charger without Solar Integration

$1,200

Reliable Level-2 charging on a dedicated 240V circuit. Simple, fast, and code-clean.

We’ll coordinate breaker sizing, cable runs, and code clearances with your electricians and provide neat mounting and labeling standards.

How the builder program works

  1. 1) Plan Set Review

    We review elevations, panel schedules, roof sets, and lot options.

  2. 2) Scope & Standards

    Conduit routes, roof standoffs, equipment locations, placards, and labels.

  3. 3) Scheduling

    We align with framing, roofing, electrical rough-in, and inspections.

  4. 4) Install & Commission

    Our in-house crew completes set-out, wiring, QA, and owner hand-off.

Deliverables & coordination

  • • Lot-by-lot layout and bill of materials
  • • Utility interconnection package (where applicable)
  • • Labeling and owner documentation set
  • • Final QC photos and commissioning report
