UPDATE: I bought a new house and Robbie came out to fo a gas line test for me. Great service, as always. Socially distant, polite, friendly, and knowledgeable. Joshua from HEP came out to do the summer inspection and found an issue the company (listed in the review below) caused by shoddy workmanship. So glad I have now switched everything over to HEP. Will came out at 1:30am to fix my HVAC. I had a bad capacitor and the repair took 15 minutes. This was after Mike, at A1 Finchum told me he'd workedworked 16 hours and it would not be fixed until morning, and oh there were 3 ahead of me. Kicker, I have Multiple Sclerosis and can not tolerate heat. HEP was prompt and a lifesaver. Total cost was under $500. Much appreciated!

Melissa L.

HEP installed our Trane unit a couple of years ago and were here yesterday to inspect the system as part of our agreement with them. The technician was very nice, called ahead, arrived on time, put disposable covers over his shoes before entering our home. He did a thorough job with the inspection and gave us hints on the filters we need to be using for most efficient operation. We have used them for electrical problems and for plumbing issues and have always been very satisfied with the work. I like that they answer the phone when you call as opposed to getting a recording. When they give you a range on the time that they will be coming, they always honor it. We first used them for an electrical emergency about three years ago and have had them back several times since and have always been happy with the service.

Billie P.

Hep has done a lot of things at our house...windows, doors, A/C, electrical...never disappointed with the service or quality of work!

Sheryl L.

HEP has been wonderful. I created an electrical problem which when I call HEP they sent out a tech who fixed it and then looked at my heating unit. I have known for sometime that the unit needed to be replaced. Doug was kind enough to evaluate the current system and at his suggestion I asked for a salesman to meet with me. He was kind enough to get the salesman here the same day and I purchased a unit that they are installing now. It has been like clockwork, each piece of the puzzle coming together. HEP you have a great team that knows how to work in sync. Thank you so much.

Priscilla J.

David Nicholson was the HEP employee that did my electrical inspection today. He called ahead of time and gave me a time of arrival. He arrived on time, introduced himself, and was very professional and courteous . He explained what the inspection would cover and ask if I had any questions or concerns. HEP should be proud to have such an awesome employee.

Elevated locations around Walland often experience minimal shading from vegetation or neighboring structures.

Environmental and Economic Benefits

Reduced greenhouse gas emissions contribute to regional air quality improvements.
Solar energy stabilizes utility bills by offsetting grid-supplied electricity.
Any excess generation can flow back to the grid, producing credit through applicable net-metering programs.

HEP’s Full-Cycle Solar Installation Workflow

HEP approaches each project as a holistic process rather than a simple panel-mounting exercise. By integrating electrical engineering principles into every step, the company ensures reliable, code-compliant, and high-yield systems.

1. Site Evaluation and Solar Feasibility

HEP’s solar specialists visit the property to take precise azimuth readings, roof pitch measurements, and shading assessments. Drone imagery or ladder inspections reveal roof material condition, rafter spacing, and potential obstructions such as chimneys or skylights. Concurrently, electrical technicians inspect the main service panel and grounding system to verify capacity for a future photovoltaic interconnection.

Key instruments used during evaluation:

Solar pathfinder tools for shading analysis
Infrared cameras for roof thermal mapping
Multimeters and clamp meters for service-panel load calculations

2. Custom System Design

After collecting field data, HEP engineers craft a system design that balances energy production, aesthetic considerations, and budgetary goals. Design outputs include:

Module layout drawings in CAD or 3D modeling software
Conductor sizing and conduit routing diagrams
Structural load calculations ensuring roof integrity

Unordered list of primary design parameters:

Target kWh offset percentage
Module orientation and tilt
Maximum inverter capacity
Grounding and bonding methodology
Rapid shutdown compliance strategy

3. Permitting and Regulatory Compliance

Walland’s jurisdiction falls under Blount County building regulations and NEC (National Electrical Code) requirements. HEP manages the permit applications, ensuring that system diagrams, load calculations, and structural details satisfy local inspectors before any hardware is purchased or installed. During this stage, HEP coordinates:

Building permits
Electrical permits
Utility interconnection agreements

4. Professional Installation

Installation involves several specialized crews coordinated in a precise timeline:

Structural crew installs flashing, mounting rails, and hardware to secure modules without compromising roof waterproofing.
Electrical crew pulls appropriately sized conductors through UV-rated conduit, installs combiner boxes, and lands conductors in the inverter.
Final crew sets up monitoring hardware, optimizers or microinverters, and performs a system-wide inspection.

5. Electrical Integration and Commissioning

HEP’s state-licensed electricians test continuity, insulation resistance, and grounding impedance before energizing the system. Critical commissioning steps include:

Verifying array open-circuit voltage and short-circuit current match design expectations
Confirming inverter firmware and utility grid parameters
Testing rapid shutdown functionality at the rooftop junction box

Once performance metrics pass the internal checklist, a local electrical inspector conducts a final walkthrough. The array is then authorized to operate (PTO) via the utility.

The Importance of Electrical Precision in Solar Installations

In any photovoltaic array, solar panels merely collect photons. The overarching system must route those electrons safely through conductive pathways, convert DC to AC, synchronize output with grid frequency, and protect every component from electrical faults. HEP’s meticulous electrical craftsmanship safeguards performance and longevity.
