The Solar Energy Industries Association (SEIA) aims for solar power to generate 30% of U.S. electricity by 2030. As part of this growth, solar carports are becoming an increasingly popular solution for residential, commercial, and industrial applications.
For solar installation companies, expanding into solar carport installations can be a strategic move. With solar panel prices remaining low and EV adoption surging, the demand for solar panel carports with EV charging is expected to rise in the coming years.
In this article, we’ll explore what a solar carport is, how it works, and the key advantages and challenges of offering carport solar solutions.
What Is A Solar Carport?
A solar carport is a covered parking structure equipped with photovoltaic (PV) panels, allowing for both solar energy generation and vehicle protection. This dual-purpose design optimizes space, making it a practical solution for homeowners, businesses, and organizations looking to adopt renewable energy while providing shaded parking.
Many solar panel carports integrate EV chargers, enabling electric vehicle owners to charge their cars using clean solar power. Residential solar carports range from single-vehicle structures in driveways to large-scale commercial solar carports covering entire parking lots.
For homeowners interested in DIY solar carport kits, some manufacturers offer pre-engineered solutions that reduce installation costs and simplify the process. Whether for residential or commercial use, carport solar systems provide a sustainable energy solution while enhancing property functionality.
How Does A Solar Carport Work?
A solar carport operates similarly to a ground-mounted PV system, but with the added function of providing covered parking. Instead of installing solar panels on a rooftop, solar panel carports use an elevated steel or aluminum canopy structure to support photovoltaic (PV) panels above a parking area.
Unlike traditional rooftop solar systems, carport solar structures allow for optimal panel tilt and orientation, maximizing solar energy generation. These structures are designed to provide adequate clearance for vehicles while incorporating weather-resistant materials to withstand environmental conditions.
Why Choose a Solar Carport?
For homeowners and businesses with limited roof space or shading issues, a solar carport system is a practical alternative. A solar PV carport is ideal when:
Trees or buildings cast excessive shade over the property.
Chimneys, vents, or gables reduce available rooftop space.
Small or complex roof designs make solar panel installation impractical.
The roof’s orientation isn’t optimal for solar energy production.
Also, commercial solar carports can integrate EV charging stations, making them an efficient solution for businesses looking to support electric vehicle adoption while reducing energy costs. With solar carports, properties can achieve higher energy output, better system accessibility for maintenance, and increased renewable energy adoption without roof limitations.
How Much Does A Solar Carport Cost?
The cost of a solar carport in the U.S. typically ranges between $3.75 and $4.50 or more per watt, depending on factors like location, materials, labor, and system size. This price includes solar panels, the carport structure, wiring, permitting, and installation.
A 5-kilowatt (kW) residential solar carport costs between $18,750 and $22,500 before the federal solar tax credit.
Larger commercial solar carports benefit from economies of scale, bringing costs down to around $2.75 to $3.50 per watt for larger installations.
Why Are Solar Carports More Expensive Than Rooftop Solar?
Carport solar panel installations typically cost more than rooftop solar due to the added expense of the steel or aluminum canopy structure and foundation work. Additionally, residential solar carports tend to have a higher cost per watt than commercial installations because smaller systems don't benefit from bulk material purchasing and streamlined labor costs.
Despite the higher upfront cost, solar panel carports provide additional benefits, including vehicle protection, better panel orientation, and the potential for integrated EV charging stations, making them a valuable long-term investment.

The Benefits of a Solar Carport
A solar carport is a smart dual-purpose solution, providing vehicle shade while generating clean solar energy. Unlike ground-mounted systems, a solar panel carport efficiently utilizes parking spaces, making it ideal for residential and commercial applications.
✅ 1. Lower Energy Bills
A solar carport turns underutilized space into a mini power plant, allowing property owners to generate on-site renewable energy instead of relying on the grid. By reducing electricity consumption from the utility, a carport solar system helps lower energy costs.
If the system produces excess electricity, homeowners and businesses may benefit from net energy metering (NEM), selling surplus solar power back to the grid for credits on their utility bills.
✅ 2. Maximizing Land Use Efficiency
Unlike standard ground-mounted solar systems, which require dedicated land, a solar carport optimizes space by integrating solar panels into parking areas. This is especially beneficial for commercial properties where parking lots become renewable energy generators without sacrificing usable land.
Expanding commercial solar carports in parking lots can also help preserve agricultural land by reducing the need for large-scale solar farms.
✅ 3. Protecting Vehicles From The Elements
A solar panel carport does more than produce energy—it shields vehicles from harsh weather. In hot climates like California, Arizona, and New Mexico, solar carports reduce interior vehicle temperatures, making commutes more comfortable. In colder regions, they offer protection from rain, sleet, hail, and snow, helping prolong vehicle lifespan.
✅ 4. EV-Charging & Solar Carports
Solar carports with EV chargers combine solar power and electric vehicle (EV) infrastructure, creating a sustainable charging solution.
Residential solar carports let homeowners charge EVs with solar-generated electricity, reducing reliance on fossil fuels.
Commercial solar carports with EV chargers provide an added amenity for customers and employees, while businesses can monetize charging stations as a new revenue stream.
✅ 5. Solar Power Generation
A solar carport system is often more effective than a rooftop solar array when:
Roof space is limited or obstructed by vents, chimneys, or skylights.
Trees or nearby buildings create excessive shading.
The carport can be oriented for optimal sun exposure to maximize energy production and financial returns.
The Disadvantages of a Solar Carport
While solar carports offer significant benefits, there are technical and financial challenges to consider before installation.
