HVAC Technicians and Solar Installers both work on building-energy systems, but they solve different problems.
An HVAC Technician installs, maintains, diagnoses, and repairs heating, air-conditioning, ventilation, and refrigeration equipment. A Solar Installer assembles and installs photovoltaic systems that convert sunlight into electricity.
For federal occupational data, CareerInTrades uses:
- HVAC Technician: SOC 49-9021 — Heating, Air Conditioning, and Refrigeration Mechanics and Installers.
- Solar Installer: SOC 47-2231 — Solar Photovoltaic Installers.
The central career difference is:
HVAC is a larger service-and-repair occupation built around an enormous installed base of mechanical equipment. Solar installation is a smaller construction occupation growing rapidly as more photovoltaic systems are installed.

- Verifying that repairs corrected the original malfunction
HVAC Is a Troubleshooting Career
Installation is only one part of HVAC work.
A service Technician may arrive at a building knowing only that the system is not heating or cooling correctly.
The cause might involve:
- Electrical components
- Refrigerant charge
- Airflow
- Controls
- Motors
- Compressors
- Sensors
- Thermostats
The Technician must isolate the failure rather than simply install a predetermined component.
That diagnostic responsibility is one of the most important differences from entry-level Solar Installer work.
What Does a Solar Installer Actually Do?
O*NET defines Solar Photovoltaic Installers as workers who assemble, install, or maintain PV systems on roofs or other structures according to site assessments, schematics, codes, and standards.
O*NET 2026 reported job titles include:
- PV Installer
- PV Installation Technician

- Following drawings and schematics
- Weather-sealing roof penetrations
- Testing system components
- Performing maintenance
O*NET notes that the occupation may include minor electrical work such as current checks. The electrical work a particular Solar Installer may legally perform depends on the worker’s qualifications and applicable state and local rules.
Solar Installation Is Primarily a Construction-Installation Career
A residential solar crew typically arrives with a defined system design and must turn that design into a safe, weather-resistant physical installation.
That makes important skills include:
- Roof layout
- Measurement
- Mounting
- Module handling
- Weatherproofing
- Electrical awareness
- Fall protection
- Working efficiently as a crew
Advanced Solar Technicians can develop deeper electrical, commissioning, battery-storage, troubleshooting, and system-design skills, but those should not be assumed to be part of every entry-level PV Installer position.
Mechanical Troubleshooting vs Renewable-Energy Installation
| Skill Area | HVAC Technician | Solar Installer |
|---|---|---|
| Mechanical Troubleshooting | Critical | Limited to moderate |
| Electrical Troubleshooting | Important | Important in advanced roles |
| Refrigeration Knowledge | Critical | Not relevant |
| Airflow Diagnostics | Critical | Not relevant |
| Roof Layout | Occasional | Critical for rooftop PV |
| Structural Mounting | Moderate | Critical |
| PV System Knowledge | Not normally required | Critical |
| Customer Service Diagnostics | Very important | Less central in installation-only positions |
Salary Comparison: HVAC Technician vs Solar Installer
| May 2024 Wage Measure | HVAC Technician | Solar Installer | Difference |
|---|---|---|---|
| Median Annual Wage | $59,810 | $51,860 | HVAC +$7,950 |
| Median Hourly Wage | $28.75 | $24.93 | HVAC +$3.82/hour |
| Lowest 10% | Below $39,130 | Below $39,070 | Nearly identical lower end |
| Highest 10% | Above $91,020 | Above $80,150 | HVAC has the higher national upper range |
Why HVAC Pays More at the Median
The $7,950 median wage difference reflects more than installation difficulty.
An experienced HVAC Technician may be expected to diagnose failures across several technical domains at the same time:
- Mechanical systems
- Electrical circuits
- Refrigeration
- Airflow
- Controls
- Combustion equipment in applicable systems
The Technician may also need to restore service quickly because loss of heating, cooling, or refrigeration can disrupt a home, business, healthcare facility, restaurant, or other building.
Solar Installer work is skilled construction work, but many entry-level positions are more installation-centered and can be learned through moderate-term on-the-job training.
Solar Pay Can Improve With Technical Specialization
The $51,860 median should not be interpreted as the earnings ceiling for someone who enters the solar industry.
BLS May 2024 data show notable differences by industry. Median wages for Solar Photovoltaic Installers included:
| Industry | May 2024 Median Wage |
|---|---|
| Plumbing, Heating, and Air-Conditioning Contractors | $61,140 |
| Electrical Contractors and Other Wiring Installation Contractors | $59,130 |
| Power and Communication Line and Related Structures Construction | $50,960 |
| Utilities | $50,120 |
These figures show why the employer and technical scope matter.
A worker who develops electrical capability, commissioning knowledge, battery-storage skills, troubleshooting ability, or related trade credentials can follow a different career path from someone who remains focused only on basic module installation.
Job Outlook: HVAC Technician vs Solar Installer
| 2024–2034 Labor-Market Measure | HVAC Technician | Solar Installer | Interpretation |
|---|---|---|---|
| Employment, 2024 | 425,200 | 28,600 | HVAC starts with nearly 15 times as many jobs. |
| Projected Employment, 2034 | 459,700 | 40,600 | Solar remains much smaller even after rapid expansion. |
| Projected Growth | 8% | 42% | Solar has more than five times the percentage growth rate. |
| Net New Jobs | +34,500 | +12,000 | HVAC still creates almost three times as many net new positions. |
| Average Annual Openings | About 40,100 | About 4,100 | HVAC offers nearly ten times as many annual openings. |
Why 42% Solar Growth Does Not Mean More Solar Jobs
This is the most important statistical distinction in this comparison.
Solar Installer is one of the fastest-growing occupations in the United States, with projected employment growth of approximately 42% from 2024 to 2034.
But percentage growth measures how quickly an occupation expands relative to its starting size.
Solar Installer starts from only about 28,600 jobs.
HVAC Technician starts from approximately 425,200 jobs.
As a result:
- Solar Installer adds approximately 12,000 jobs.
- HVAC Technician adds approximately 34,500 jobs.
The same effect appears in annual openings:
- HVAC Technician: about 40,100.
- Solar Installer: about 4,100.
Solar therefore has the stronger growth rate, while HVAC has the stronger job-market scale.
Why HVAC Demand Is Growing
HVAC demand comes from both new systems and the enormous installed base of existing equipment.
BLS identifies factors including:
- Commercial and residential construction
- Increasingly sophisticated climate-control systems
- Repair and replacement of existing HVAC systems
- Energy-efficiency improvements
- Pollution-reduction requirements
Every installed HVAC system eventually requires some combination of inspection, maintenance, diagnosis, repair, or replacement.
That creates recurring work after the original installation is complete.
Why Solar Installer Is Growing So Fast
Solar employment is expanding because more photovoltaic systems are being installed.
The growth model is therefore different from HVAC.
Solar demand is strongly connected to:
- New residential PV installations
- Commercial solar projects
- Utility-scale solar development
- Expansion of distributed energy systems
- Declining long-term PV system costs
This creates a much higher percentage growth rate because the occupation is expanding from a relatively small employment base.
Which Career Has the Stronger Labor-Market Position?
| Career Question | Advantage | Why |
|---|---|---|
| Higher Median Wage | HVAC Technician | $59,810 versus $51,860. |
| Faster Percentage Growth | Solar Installer | 42% versus 8%. |
| More Net New Jobs | HVAC Technician | +34,500 versus +12,000. |
| More Annual Openings | HVAC Technician | About 40,100 versus 4,100. |
| Larger Employment Base | HVAC Technician | 425,200 versus 28,600. |
| Faster-Growing Renewable-Energy Entry | Solar Installer | PV installation is one of the fastest-growing U.S. occupations. |
| Recurring Repair Demand | HVAC Technician | Existing mechanical systems continually require maintenance and repair. |
| Faster Initial Training | Solar Installer | High school plus moderate-term on-the-job training is the typical BLS entry model. |
Training Requirements: HVAC Technician vs Solar Installer
| Training Factor | HVAC Technician | Solar Installer |
|---|---|---|
| Typical Entry Education | Postsecondary nondegree award commonly used | High school diploma or equivalent |
| On-the-Job Training | Lengthy training after hire is common | Moderate-term training |
| Mechanical Systems | Critical | Limited |
| Electrical Fundamentals | Important | Important |
| Refrigeration | Critical | Not required |
| Roof / Fall-Protection Skills | Occasional | Critical for rooftop installation |
| Diagnostic Training | Extensive | Becomes more important in advanced service roles |
How to Become an HVAC Technician
HVAC Technicians commonly complete technical education before entering full-time field work, although pathways vary.
A typical route may include:
- Complete high school or equivalent.
- Complete an HVAC certificate, technical-school, community-college, or apprenticeship program.
- Learn refrigeration principles.
- Learn electrical fundamentals and controls.
- Learn heating and cooling equipment operation.
- Complete supervised field training.
- Obtain EPA Section 608 certification when performing covered refrigerant work.
- Develop installation and diagnostic experience.
- Add commercial, refrigeration, controls, heat-pump, or building-automation specialization.
EPA Section 608 Matters for HVAC Careers
Technicians who maintain, service, repair, or dispose of equipment that could release regulated refrigerants may be required to obtain certification under EPA Section 608 requirements.
This is an important distinction between HVAC and Solar Installer training.
HVAC career progression frequently involves refrigerant handling and a federal environmental certification framework that does not apply to ordinary PV module installation.
How to Become a Solar Installer
BLS identifies a high school diploma or equivalent as the typical entry-level education for Solar Photovoltaic Installers, followed by moderate-term on-the-job training.
A typical path may include:
- Complete high school or equivalent.
- Enter an entry-level PV installation position or relevant technical program.
- Learn construction and fall-protection safety.
- Learn roof layout and mounting systems.
- Learn PV modules and system components.
- Learn to read plans and schematics.
- Develop basic electrical knowledge within permitted scope.
- Build installation experience.
- Progress toward electrical, commissioning, storage, design, or supervisory skills where appropriate.
Which Career Is Easier to Enter?
Solar Installer generally has the faster entry path.
BLS identifies high school completion followed by moderate-term on-the-job training as the typical entry model.
HVAC usually requires more technical preparation because the Technician must eventually understand multiple interacting systems rather than only installation procedures.
That additional training creates a tradeoff:
Solar can get a worker into field installation faster. HVAC takes longer to develop but builds a broader diagnostic skill set that supports maintenance and repair work throughout the life of the equipment.
Licensing and Certification
Neither career has one universal employee license covering every worker in every state.
The applicable rules depend on the state, work scope, contractor, and whether the worker performs regulated electrical, refrigerant, or contracting work.
| Credential Area | HVAC Technician | Solar Installer |
|---|---|---|
| Federal Refrigerant Certification | EPA Section 608 applies to covered refrigerant work | Not normally applicable |
| Electrical Work | Part of many HVAC systems, subject to applicable rules | Important, with legal scope depending on jurisdiction and qualifications |
| Contractor Licensing | State contractor rules may apply | State solar/electrical contractor rules may apply |
| Fall-Protection Training | Relevant in some work | Especially important for rooftop PV |
HVAC Contractor Licensing Example: California
California’s Contractors State License Board maintains the C-20 Warm-Air Heating, Ventilating and Air-Conditioning Contractor classification.
The official C-20 scope includes fabrication, installation, maintenance, service, and repair of:
- Warm-air heating systems
- Ventilating systems
- Air-conditioning systems
- Ducts and registers
- Flues
- Humidity controls
- Thermostatic controls
- Air filters associated with these systems
California also specifies that this classification includes warm-air heating, ventilation, and air-conditioning systems that use solar energy.
The C-20 is a contractor classification. It should not be interpreted as meaning every employee HVAC Technician must personally hold a C-20 contractor license.
Solar Contractor Licensing Example: California
California maintains a separate C-46 Solar Contractor classification for solar contracting.
The classification covers solar energy systems within its legally defined scope.
Solar projects can also intersect with electrical, roofing, HVAC, or other regulated work depending on system design and project scope.
The C-46 is a contractor classification rather than a universal individual Solar Installer employee license.
Workers and contractors should verify which classification or individual credential is required for the actual work being performed rather than assuming that one solar credential covers every electrical or construction activity.
Work Environment: HVAC Technician vs Solar Installer
The work environment creates one of the clearest differences between these careers. HVAC Technicians move between indoor and outdoor mechanical systems and frequently enter existing buildings to diagnose equipment problems. Solar Installers spend much more time outdoors, particularly on roofs and exposed construction sites.
| Work Environment Factor | HVAC Technician | Solar Installer | Why It Matters |
|---|---|---|---|
| Indoor Work | Very common | Limited for field installers | HVAC provides a more mixed indoor/outdoor environment. |
| Outdoor Work | Common | Very common | Solar installation is more consistently exposed to weather. |
| Roof Work | Possible | Very common in residential PV | Comfort with heights matters much more in rooftop solar. |
| Mechanical Rooms | Very common | Limited | HVAC Technicians regularly work around mechanical equipment. |
| Crawlspaces / Attics | Common | Possible but less central | HVAC can involve cramped and hot interior spaces. |
| Customer Homes | Very common in residential service | Common during residential installation | HVAC usually creates more repeat service visits after installation. |
| Large Commercial Projects | Common | Common | Both careers extend beyond residential work. |
| Utility-Scale Projects | Rare | Important solar market | Solar can provide access to large outdoor energy projects. |
HVAC Technician Work Environment
BLS reports that HVAC Technicians work in homes, schools, hospitals, office buildings, factories, and other structures.
A Technician may move during the same day between:
- Outdoor condensing units
- Mechanical rooms
- Attics
- Crawlspaces
- Rooftops
- Customer living spaces
- Commercial equipment rooms
The occupation can involve uncomfortable temperatures because the Technician is often called precisely when heating or cooling equipment is not working.
BLS also notes that HVAC Technicians may work evenings or weekends, be on call, and work overtime during peak heating and cooling seasons.
Solar Installer Work Environment
Solar Installers work primarily outdoors, although the exact environment changes with residential, commercial, and utility-scale projects.
Residential PV installation commonly requires workers to:
- Access roofs
- Carry and position modules
- Install mounting hardware
- Work around roof edges
- Seal penetrations
- Follow fall-protection procedures
- Coordinate with other installation crew members
Utility-scale solar changes the environment from rooftops to large ground-mounted sites, but workers remain heavily exposed to outdoor weather conditions.
Schedule and Seasonal Demand
| Schedule Factor | HVAC Technician | Solar Installer |
|---|---|---|
| Standard Day Schedule | Common | Common |
| Emergency Service | Common in service HVAC | Much less central |
| On-Call Work | Possible | Less common in installation roles |
| Peak-Season Overtime | Common during extreme heating or cooling demand | Possible during busy construction periods |
| Weather Delays | Moderate | More important for rooftop and outdoor installation |
| Project-Based Scheduling | Important in installation work | Very important |
HVAC Has More Emergency-Service Pressure
The service side of HVAC creates a work pattern that Solar Installers encounter less often.
A failed air-conditioning system during extreme heat, failed heating during cold weather, or failed refrigeration equipment in a commercial facility can require rapid diagnosis and repair.
That can create:
- After-hours calls
- Weekend work
- Peak-season overtime
- On-call schedules
Solar installation is generally more project-scheduled. System service and troubleshooting exist, but emergency response is not as central to the occupation as it is in HVAC service.
Physical Demands
| Physical Demand | HVAC Technician | Solar Installer |
|---|---|---|
| Standing / Walking | Very common | Very common |
| Lifting Equipment | Common | Common |
| Kneeling / Crouching | Very common | Common |
| Working in Tight Spaces | Very common | Less central |
| Roof Work | Possible | Very common in residential PV |
| Working at Height | Possible | Major consideration |
| Outdoor Heat Exposure | Common | Very common |
| Fine Diagnostic Work | Critical | More important in advanced service roles |
Safety Risks
HVAC Technician Safety Risks
BLS reports that HVAC Technicians have one of the higher rates of injuries and illnesses among occupations.
Important hazards include:
- Electrical hazards
- Chemical burns
- Refrigerant exposure
- Strains and sprains from handling heavy equipment
- Ladders and rooftop work
- Hot or cold working environments
- Moving mechanical equipment
Solar Installer Safety Risks
Solar Installer hazards are more closely tied to construction, electrical systems, outdoor exposure, and working at height.
Important risks include:
- Falls from roofs
- Ladder accidents
- Electrical hazards
- Heat exposure
- Weather
- Manual handling of modules and equipment
- Construction-site hazards
Safety Comparison
| Hazard Type | HVAC Technician | Solar Installer |
|---|---|---|
| Electrical Exposure | Important | Important |
| Refrigerant Exposure | Important | Not normally applicable |
| Roof / Fall Exposure | Possible | Major risk in rooftop PV |
| Extreme Temperature Work | Important | Important outdoors |
| Heavy Equipment Handling | Important | Module and mounting-system handling important |
| Confined Spaces | More common | Less central |
Technology and the Energy Transition
Both occupations are affected by changes in how buildings produce and consume energy, but the opportunity appears in different parts of the building.
Technology in HVAC
HVAC Technicians increasingly encounter:
- High-efficiency heat pumps
- Variable-speed compressors
- Electronic expansion controls
- Smart thermostats
- Building automation
- Advanced sensors
- Connected diagnostic systems
- More sophisticated climate controls
This can make HVAC work more technical rather than simply making it easier.
A Technician who understands mechanical refrigeration but cannot troubleshoot sensors, electronic controls, motors, or modern system communications may have a narrower skill set than employers need on newer equipment.
Technology in Solar
Solar workers increasingly encounter systems involving:
- Higher-efficiency PV modules
- Microinverters
- String inverters
- Rapid-shutdown equipment
- System monitoring
- Battery storage
- Energy-management systems
The strongest long-term solar career path therefore extends beyond physically attaching panels to a roof.
Workers who develop electrical, commissioning, troubleshooting, battery-storage, and system-integration knowledge can move into more technically demanding positions.
Which Career Is More Resistant to Automation?
Both occupations require substantial field work and are difficult to automate completely.
HVAC service has a particularly strong barrier to automation because Technicians work on existing systems with different:
- Equipment ages
- Brands
- Control systems
- Duct configurations
- Previous repairs
- Installation conditions
A Technician must diagnose the actual failure and physically repair equipment in the building.
Solar installation also requires site-specific physical work, particularly on roofs. However, standardized system designs, prefabricated components, improved mounting systems, and increasingly efficient installation processes can reduce labor hours per installation.
That does not eliminate Solar Installers, but it makes technical progression important.
The more a Solar worker can contribute to electrical work, commissioning, troubleshooting, storage, and system integration, the less dependent the career becomes on basic repetitive panel installation.
Can HVAC and Solar Skills Complement Each Other?
Yes, particularly as buildings become more electrified.
A building may combine:
- Solar PV
- Battery storage
- Heat pumps
- Smart thermostats
- Electrical load management
- Building automation
But HVAC Technician and Solar Installer should not be treated as interchangeable occupations.
A Solar Installer does not automatically have the refrigeration and mechanical diagnostic training needed for HVAC service. An HVAC Technician does not automatically have the qualifications required to perform all PV electrical or solar contracting work.
The overlap is strongest for workers and companies operating at the intersection of building electrification, energy efficiency, controls, and distributed energy.
Best Long-Term Skill Strategy
| Career | Best Long-Term Skill Strategy |
|---|---|
| HVAC Technician | Develop refrigeration, electrical diagnostics, heat-pump expertise, controls, commercial HVAC, and building-automation skills. |
| Solar Installer | Progress beyond module installation into electrical systems, commissioning, troubleshooting, battery storage, and energy-system integration where licensing allows. |
| Worker Interested in Building Electrification | Build a strong primary trade first, then add complementary knowledge in electrical systems, controls, storage, or energy management. |
Career Advancement
| Career Stage | HVAC Technician | Solar Installer |
|---|---|---|
| Entry | HVAC Installer / Apprentice / Junior Technician | PV Installer / Installation Technician |
| Experienced Worker | HVAC Service Technician | Experienced Solar Installer / Lead Installer |
| Technical Specialization | Commercial HVAC, Refrigeration, Controls, Heat Pumps | Electrical, Commissioning, Storage, Troubleshooting |
| Leadership | Lead Technician / Foreman | Crew Lead / Installation Supervisor |
| Management | Service Manager / Project Manager | Project Supervisor / Solar Operations Manager |
| Business Ownership | HVAC Service / Contracting Company | Solar Contracting / Installation Company |
Which Career Has the Stronger Advancement Path?
HVAC has a more established technical progression because installation is only the beginning of the equipment lifecycle.
An experienced Technician can move toward:
- Advanced service diagnostics
- Commercial HVAC
- Refrigeration
- Controls
- Building automation
- Service management
- Contracting
Solar has a newer and faster-growing career structure.
An Installer who remains focused only on basic module mounting may have a narrower technical path. An Installer who develops electrical, commissioning, storage, troubleshooting, design, or project-management capability can move into substantially more advanced work.
The difference is therefore:
HVAC has technical progression built naturally into service and repair. Solar workers often need to deliberately add electrical and energy-system skills to move beyond installation.
Business Ownership: HVAC Service vs Solar Contracting
HVAC Business
HVAC has a strong recurring-service business model.
A contractor can potentially generate revenue from:
- New installations
- System replacements
- Preventive maintenance
- Emergency repairs
- Refrigeration service
- Indoor-air and ventilation work
- Heat-pump upgrades
- Commercial service agreements
A major advantage is that the relationship with a customer does not necessarily end after installation.
The same equipment can require maintenance, repairs, parts replacement, and eventual system replacement over many years.
Solar Contracting Business
Solar contracting is more project-driven.
Revenue can come from:
- Residential PV installations
- Commercial installations
- System upgrades
- Battery-storage projects
- Maintenance
- Troubleshooting
The business can benefit from rapid market expansion, but new-installation volume can be more sensitive to financing conditions, electricity economics, permitting, equipment prices, and changes in incentives or utility rules than recurring HVAC repair demand.
Business Ownership Comparison
| Business Factor | HVAC Business | Solar Business |
|---|---|---|
| Recurring Maintenance | Very strong | Lower |
| Emergency Service | Strong revenue source | Limited |
| New Installation Growth | Strong | Very strong in a rapidly expanding market |
| Existing Installed-Base Demand | Very strong | Growing as more PV systems age |
| Customer Repeat Potential | High | Lower for installation-only businesses |
| Electrical Scope Importance | Important | Very important |
| Exposure to Project / Financing Cycles | Moderate | Higher for installation-focused businesses |
| Service-Agreement Potential | Very strong | Developing |
Who Should Choose HVAC Technician?

Final Verdict: HVAC Technician vs Solar Installer
The headline numbers can make Solar Installer appear to have the stronger labor market because its projected growth rate is approximately 42%, compared with 8% for HVAC Technician.
That interpretation misses the difference in occupational scale.
Using 2024–2034 projections:
- HVAC Technician: 425,200 jobs growing to 459,700, adding about 34,500 positions and generating approximately 40,100 annual openings.
- Solar Installer: 28,600 jobs growing to 40,600, adding about 12,000 positions and generating approximately 4,100 annual openings.
Solar Installer grows much faster in percentage terms, but HVAC starts with nearly 15 times as many jobs, adds almost three times as many net positions, and provides nearly ten times as many annual openings.
The wage comparison also favors HVAC.
Using May 2024 data:
- HVAC Technician median: $59,810.
- Solar Installer median: $51,860.
That is a difference of approximately $7,950 per year.
These statistics reflect the different maturity of the occupations.
HVAC is already a large skilled-service market. Millions of homes and commercial buildings depend on heating, cooling, ventilation, and refrigeration equipment that must be maintained and repaired after installation.
Solar is a much smaller occupation expanding rapidly as additional PV capacity is installed.
That makes Solar Installer particularly attractive for someone who specifically wants renewable-energy construction and prefers a faster entry route. The strongest long-term solar path, however, is usually not to remain limited to basic module installation. Electrical knowledge, commissioning, battery storage, troubleshooting, and system integration can substantially broaden the worker’s role.
HVAC requires more technical preparation, but that complexity is also one of its advantages. A Technician can build expertise across mechanical systems, refrigeration, electrical diagnostics, controls, heat pumps, commercial equipment, and building automation.
The business models also differ.
A solar installation company can participate in a rapidly expanding market, but much of its revenue is tied to winning new projects. An HVAC contractor can sell new systems while also generating recurring revenue from maintenance, repair, emergency service, and replacement of existing equipment.
For someone equally interested in both careers and primarily seeking the broader long-term technician career, HVAC offers the larger labor market, higher median wage, substantially more annual openings, deeper diagnostic progression, and stronger recurring-service structure.
For someone specifically motivated by photovoltaic energy, comfortable with rooftop and outdoor construction, and willing to progress beyond basic installation into electrical, storage, commissioning, or system-integration skills, Solar Installer offers a much faster-growing occupational pathway.
For this pair, the most useful decision is therefore not “8% growth or 42% growth?” It is whether you want to become a service technician responsible for keeping complex building equipment operating or an installation specialist building the rapidly expanding photovoltaic energy infrastructure.
