Introduction: The Craft of Solar Installation
Seven years ago, Josh Ford took a pay cut to work for Namasté Solar in Boulder, Colorado. He had been remodeling houses, but that work was not doing anything for the planet. “With all the crap going on in the world,” he says, “I wanted to feel like I was working for a better tomorrow.” His story encapsulates a growing movement in the construction trades: skilled workers who see residential solar panel installation not just as a technical job, but as a craft to be mastered and a meaningful contribution to a sustainable future.
Namasté Solar was founded a dozen years ago by three friends who started out delivering solar panels to job sites on bicycles. Today, 175 people work for the company, and nearly half of them are co-owners including Ford. The work of installing photovoltaic panels on existing homes is dangerous, demanding, and deeply rewarding. This article explores the craft of PV installation the safety culture that underpins it, the technical skills required, and what it takes to build a career in solar energy.
The Safety-First Culture of Residential PV Installation
Daily Hazard Assessment Rituals
The first thing Ford and his crew do when they arrive at a job, before they even say “good morning” to the customer, is talk safety. They walk around the house and identify hazards, from overhead power lines to aggressive dogs. “We do this on every single job,” Ford explains. “We are not just clocking in, clocking out, and getting our paychecks. We all look out for each other. It is part of the culture.” This daily ritual is the foundation upon which every successful solar installation is built.
A thorough job site safety walk includes the following checks:
- Overhead power lines and their proximity to the work area
- Roof condition including soft spots, rot, and structural integrity
- Weather conditions such as wind speed, rain, and extreme heat
- Access to the roof via ladders and scaffolding
- Presence of pets, children, or other site-specific hazards
- Location of emergency equipment and first aid supplies
Roof Safety Systems and Fall Protection
Working on steep residential roofs is one of the most dangerous aspects of PV installation. Professional installers use a combination of personal fall arrest systems (PFAS), roof anchors, and safety lines to mitigate the risks. OSHA regulations require that anyone working at heights of six feet or more on a residential roof must have adequate fall protection. Experienced crews use permanent or temporary roof anchors rated to withstand at least 5,000 pounds of force per attached worker.
Key pieces of fall protection equipment used by professional PV installers include:
- Full-body harnesses with dorsal D-rings
- Self-retracting lifelines (SRLs) for mobility
- Roof anchors that attach to rafters or structural members
- Guardrail systems for flat or low-slope roofs
- Safety netting for complex roof geometries
Extreme Weather Preparedness
Solar installers work in all seasons. Heat stress, cold exposure, and lightning risk are real concerns. Ford and his crew have protocols for extreme weather: they stop work when wind speeds exceed 25 mph, when there is lightning within 10 miles, or when temperatures create unsafe working conditions. Hydration breaks, shaded rest areas, and appropriate clothing are non-negotiable. A responsible crew checks the forecast every morning and plans the workday around weather windows.
Technical Skills and Craftsmanship in PV Installation
Mounting Systems and Roof Attachment
The first technical challenge on any residential installation is securely attaching the mounting system to the roof structure. Installers must identify rafter locations, use appropriate flashing to prevent leaks, and select the right fasteners for the roofing material. Composition shingles, standing seam metal, clay tiles, and slate each require different attachment strategies. A flashing-boot and sealant system must be installed under the shingle course above each attachment point to maintain the roof’s weathertight integrity.
Common mounting approaches include:
- Rafter-mounted attachments used for composition shingle and shake roofs, where L-feet or standoffs are bolted directly to rafters through the decking
- Standing seam clamps that attach to the raised seams of metal roofs without any roof penetration
- Tile hooks and replacement pans for clay tile and concrete tile roofs that allow tiles to be removed reinstalled around attachments
- Flat roof ballasted systems that use concrete blocks to hold the array in place without roof penetrations
Conduit Routing and the Art of Clean Pipe
“Going beyond what the customer wants, that is craftsmanship to me,” Ford says. He wants people to look at the conduit he ran on the side of a house and know he cared. He wants them to say, “Wow, that guy really knew how to run that pipe.” Conduit routing is one of the most visible indicators of installation quality. Professional installers plan their conduit paths to follow rooflines, ridge lines, and architectural features so the electrical raceway blends into the house rather than detracting from it.
The table below summarizes common conduit types used in residential PV installations and their recommended applications:
| Conduit Type | Material | Best Application | Corrosion Resistance |
|---|---|---|---|
| EMT (Electrical Metallic Tubing) | Galvanized steel | Interior and protected exterior runs | Moderate |
| RMC (Rigid Metal Conduit) | Galvanized or stainless steel | Exposed exterior runs, mechanical protection | High |
| PVC Schedule 40 or 80 | Plastic (PVC) | Underground runs, corrosive environments | Excellent |
| Liquidtight Flexible Metal | Galvanized steel with PVC jacket | Connections to inverters and combiner boxes | High |
Electrical Connections and Inverter Installations
Every PV system requires careful electrical work. The solar panels produce direct current (DC) electricity that must be routed to an inverter, which converts it to alternating current (AC) for use in the home. Modern systems use either string inverters with a single central unit, or microinverters attached to each panel. Each approach has trade-offs in cost, efficiency, and maintenance. Professional installers must follow the National Electrical Code (NEC) requirements for conductor sizing, overcurrent protection, grounding, and rapid shutdown systems.
Critical electrical work includes:
- Properly sizing conductors based on system voltage and amperage
- Installing overcurrent protection devices (fuses and breakers) at combiner boxes
- Bonding and grounding the array to prevent electric shock hazards
- Installing AC and DC disconnects for safe maintenance access
- Labeling all components according to code requirements
Building a Career in Solar Trades
From Remodeling to Renewable Energy
Ford’s career path from remodeling to solar installation mirrors a broader industry trend. Skilled tradespeople with experience in construction, electrical work, roofing, and carpentry are finding that their existing skills transfer directly to PV installation. The transition requires additional training in electrical theory, solar-specific codes, and system design, but the hands-on construction background gives experienced workers a significant advantage. They already know how to work on roofs, handle tools safely, and manage the logistics of a construction site.

Understanding the homeowner perspective is valuable for installers who want to communicate clearly with their clients.
Employee Ownership and Company Culture
Namasté Solar’s employee-owned structure is noteworthy. Nearly half of the 175 employees are co-owners of the company. This ownership stake creates a culture where every installer has a personal investment in the quality of the work. When workers own part of the business, they are more likely to take pride in conduit runs, double-check electrical connections, and look out for each other’s safety. Employee ownership models are becoming more common in the solar industry as companies seek to attract and retain skilled workers in a competitive labor market.

The Future of Solar Craftsmanship
Technological Advances in PV Systems
The solar industry continues to evolve rapidly. Panel efficiencies have improved dramatically, from around 15% a decade ago to over 22% for premium residential panels today. Battery storage systems are becoming more affordable and integrated, allowing homeowners to store excess solar energy for use at night or during power outages. Module-level power electronics (MLPE) such as microinverters and power optimizers have improved system performance when panels are partially shaded or oriented on different roof planes.
These advances mean that today’s PV installers must be lifelong learners. The technology that was standard five years ago has been superseded, and the skills required continue to evolve. Professional installers attend manufacturer training sessions, industry conferences, and continuing education programs to stay current.

Craftsmanship as a Competitive Advantage
In an industry where some installers prioritize speed over quality, true craftsmanship sets professionals apart. Clean conduit runs, properly flashed roof attachments, neatly organized wiring, and thorough system labeling all signal to the homeowner that their installation was done by someone who takes pride in their work. As Ford puts it, “I want to do something that actually makes a difference.” For the modern PV installer, that difference is measured not only in kilowatt-hours but also in the quality and durability of the installation itself.
The demand for skilled solar installers continues to grow as more homeowners seek energy independence and lower utility bills. Those who approach the work with a craftsman’s mindset will find ample opportunity and the satisfaction of building something that truly matters a cleaner, more resilient energy future, one roof at a time.
