Project Case Study: Scaling Up for High Energy Demand

When a homeowner has significant energy consumption, a standard 5kW or 8kW solar array simply won't make a dent in their utility bills. For this project, the homeowner needed a massive, high-yield solution capable of offsetting serious power usage. They required a contractor who could safely design, engineer, and legally permit a large-scale residential system.

Our Farmville solar team delivered a powerhouse solution: a sprawling 20.01 kW DC solar array. Installing a system of this magnitude requires intense coordination. We managed every step of the process, from generating wet-stamped structural and electrical plans to securing local zoning and building permits. We even handled the Appalachian Power (APCO) Interconnection Application, securing the necessary approvals to grid-connect the 14.95 kW AC system.‍

Key Upgrades & Materials

To maximize production without compromising the roof's integrity, we utilized premium, high-density solar components.‍The specifications for this high-capacity system included:

  • High-Density Solar Panels: We installed a massive array of 46 Hyundai 435W (HIN-T435NF) Solar Modules. These advanced N-Type TOPCon panels provide exceptional efficiency and a sleek aesthetic across the large roof space.
  • Independent Microinverters: Each of the 46 panels was paired with an individual Enphase IQ8M Microinverter. This ensures that shade on one section of the large roof does not drag down the production of the entire system.
  • Leak-Proof Mounting: To safely secure 46 panels, we utilized the UNIRAC NXT UMOUNT system with STRONGHOLD Butyl. This flashless, peel-and-stick butyl technology creates a watertight seal without the need to pry up and damage the home's existing shingles.

Flawless Inspections & "Permission to Operate"

A system this large faces strict scrutiny from county inspectors and utility companies. Because our in-house team handles the structural engineering, electrical line diagrams, and safety labeling, the project passed its final county inspection with flying colors—clearing everything from the panel mounts to the combiner box and AC disconnects.‍
