Solar carports are freestanding structures installed over parking areas, with photovoltaic panels mounted on top. Unlike rooftop systems, they do not rely on existing buildings, making them ideal for properties with limited roof space or shading issues.

What Are Solar Carports?

Solar carports are elevated canopy structures fitted with solar panels that provide shade for parked vehicles while generating clean electricity. They combine the utility of parking infrastructure with on-site solar power production, making them popular for homes, businesses, and public facilities.

As energy costs rise and EV adoption grows, solar carports are emerging as a space-efficient alternative to rooftop solar.

Why do Solar Carports Matter?

These carports matter because of the following reasons:

• They generate renewable energy without using rooftops

• They protect vehicles from sun, rain, and hail

• They support EV charging infrastructure

• They increase overall property functionality and sustainability

For commercial properties, they also demonstrate a visible commitment to clean energy and environmental responsibility.

How do Solar Carports Work?

Solar carports generate electricity by capturing sunlight with panels mounted on the canopy structure. These panels convert sunlight into direct current (DC) electricity, which then passes through an inverter to become alternating current (AC) suitable for use in homes, businesses, or commercial facilities. The electricity can be:

• Used on-site to power appliances or systems

• Fed into the grid to offset energy costs

• Stored in batteries for use when sunlight is unavailable

Many modern solar carports are equipped with integrated EV chargers, allowing vehicles to charge directly from solar-generated power. This combination of electricity generation, storage, and vehicle charging makes solar carports a versatile and sustainable energy solution.

Core Components of a Solar Carport

Understanding the components of a solar carport helps explain why these systems are durable, efficient, and functional:

• Structural Frame (Steel or Aluminum): Provides stability, supports the panels, and withstands wind, rain, and other environmental stress.

• Solar PV Panels: Capture sunlight and convert it into electricity.

• Inverters and Electrical Wiring: Convert DC power from the panels into usable AC electricity and distribute it to the site or grid.

• Mounting Hardware and Foundations: Secure the panels to the structure and provide strong, reliable support.

• Optional Battery Storage and EV Chargers: Store excess energy and enable direct charging of electric vehicles.

Proper design and engineering ensure structural integrity, optimal airflow for panel cooling, and long-term reliable performance, even in regions with high heat or frequent storms.

Solar carports depend on panels, inverters, wiring, and often EV chargers—and performance can drift over time. Sunny Energy RX offers warranty-safe diagnostics, monitoring support, and maintenance to keep power and charging reliable. Schedule a call today. 

Residential vs Commercial Solar Carports

Solar carports are designed to serve both residential and commercial properties, but their scale, purpose, and design considerations differ.

Residential solar carports are typically built to accommodate one or two vehicles. Homeowners often choose these systems to generate electricity, protect vehicles, and integrate EV charging without relying on rooftop space.

Commercial solar carports, on the other hand, are large parking canopies installed at offices, hospitals, schools, shopping centers, and public facilities. These systems are engineered for higher energy output and durability, often covering dozens or hundreds of parking spaces.

Overall, commercial solar carports benefit from economies of scale and higher energy generation, while residential carports prioritize convenience, flexibility, and household energy offset.

Solar Carports vs Rooftop Solar

How much does it cost to build a solar carport?

They typically cost more than rooftop solar systems because they require additional structural steel, engineered foundations, and specialized permitting. On average, installed costs range from $3.17 to $3.72 per watt, with final pricing influenced by system size, materials used, site conditions, and local regulations.

Are solar carports worth the investment?

Yes, such carports are worth the investment when a property requires both energy generation and covered parking. They provide long-term electricity savings, support EV charging, and add functional value to parking areas. In high-sun regions, their durability and consistent energy production can justify the higher upfront cost over time.

Are solar carports eligible for tax credits?

Yes, they generally qualify for the 30% Federal Solar Investment Tax Credit (ITC) when they are used to generate electricity for a residential or commercial property. The credit applies to eligible costs such as solar panels, inverters, mounting hardware, wiring, and installation labor.

For commercial solar carports, additional financial benefits may be available, including accelerated depreciation under the Modified Accelerated Cost Recovery System (MACRS), which can significantly reduce taxable income. Eligibility depends on system ownership, interconnection, and compliance with IRS requirements, so professional tax guidance is recommended

What are the disadvantages of solar carports?

Following are the disadvantages of solar carports:

• Higher upfront cost: Solar carports require steel or aluminum structures, foundations, and engineering work, making them more expensive than rooftop solar systems.

• Complex permitting process: Because solar carports are freestanding structures, they often require additional zoning, structural, and electrical permits.

• Longer installation timelines: Engineering reviews, inspections, and approvals can extend project timelines compared to rooftop installations.

• Structural and site requirements: Soil conditions, wind-load calculations, and foundation design must be evaluated, adding planning complexity.

• Potential zoning restrictions: Height limits, setback rules, and local ordinances may restrict where and how these carports can be installed, increasing costs or redesign needs.

Can solar carports withstand storms?

Properly engineered solar carports are designed to withstand wind, rain, and region-specific storm conditions. They are built using reinforced steel or aluminum frames, deep-set foundations, and certified mounting systems to meet local wind-load, seismic, and safety codes. In storm-prone areas, designs account for high winds, heavy rainfall, and debris impact, ensuring long-term structural stability and reliable performance.

Is it cheaper to buy a solar carport or build one?

Pre-engineered solar carport kits are typically less expensive upfront because they come with standardized components and require minimal customization. They are ideal for homeowners or businesses seeking a quicker installation and predictable costs. 

Custom-built solar carports, however, involve higher initial investment as they are engineered to match specific site conditions, maximize solar exposure, and accommodate unique design requirements. These bespoke systems offer superior durability, long-term scalability, and optimized energy production, making them a better option for larger commercial projects or sites with complex layouts.

How long do solar carports last?

Most solar carports are designed to last between 25 and 40 years, providing long-term energy generation and vehicle protection. The solar panels themselves usually come with 25-year performance warranties, ensuring that they maintain high energy output over time. The supporting steel or aluminum structures are built to withstand environmental stress, including wind, rain, and sun exposure, and can last several decades when properly maintained. 

Regular inspections, cleaning, and minor repairs help extend the lifespan of both the panels and the framework, ensuring reliable performance and continued return on investment over the system’s lifetime.
