Carport Solar Systems Explained: What It Is and How It Works
A carport solar system is the installation of solar panels on a carport. This is an efficient use of land that adopts driveways and parking spaces, rather than installing solar panels on building roofs or on land.
They help you get the most out of a solar power installation and maximise the amount of off-grid electricity you can produce. This blog post has everything you need to know about solar panel carports and how they can help take your solar power system to the next level.
Key Takeaways
- Carport solar systems are a combination of a shelter for vehicles and a solar power system in one package.
- Unlike traditional carports, solar carports are not passive structures but are active energy systems.
- In comparison to rooftop solar power systems, solar carports offer more design freedom and better solar panel orientation.
- The solar power systems are suitable for residential, commercial, and public parking areas, regardless of size.
- There are different types of solar carports, but selecting the right one is important.
What Is Carport Solar
A carport solar system is a structure designed to park cars and generate power simultaneously. It integrates the traditional carport structure with solar panels as the roof, increasing land productivity. Most carport solar systems also come with optional features like EV chargers and solar batteries.
How Solar Carports Differ From Standard Carports and Rooftop Solar Systems
A standard carport’s only function is to protect vehicles from harsh weather conditions, while a rooftop solar system’s sole purpose is to generate electricity. Meanwhile, solar carports are a combination of both; it serves as a means of protecting your vehicles from harsh climates while producing renewable energy for your buildings.
How a Carport with Solar Roof Works
A carport with a solar roof works by combining a structural parking canopy with an overhead solar array. Together, the frame, mounting system, and solar panels create a structure that both shelters vehicles and generates electricity throughout the day.
Structural Frame as the Foundation
The basic principle of a carport with a solar roof is a robust structural frame. In most cases, it is made of strong, durable materials such as steel and aluminum while being anchored firmly in the ground. The structural frame of a carport with solar must be carefully designed to ensure it remains firmly above the vehicle even as its roof receives adequate sunlight.
Solar Panels Mounted Overhead
The defining feature of a solar carport is the overhead solar panel roof, in which interconnected solar modules form the entire canopy. In both the carport with solar roof and solar canopy carport systems, the panels are positioned to maximise solar exposure while maintaining full parking functionality beneath the structure.
Power Generation and Flow
Once the solar panels capture solar energy, it is transmitted through the system and used locally or fed into a power grid for use elsewhere. This further increases the value of the solar carport over a traditional carport.
Optional EV Charging Integration
Electricity generated by a solar carport can be used to charge EVs. As electric cars gain traction, modern carport solar systems are often designed with this accommodation. The electric vehicle charging stations are often integrated into the space beneath the structure, allowing vehicles to charge while parked.
Carport Solar vs Traditional Carports
Considering solar carports vs traditional carports is common for homeowners looking to prioritize efficiency. These structures appear identical and are often used as parking spaces that shield vehicles from sun, rain, and other harsh weather at ground level. Nevertheless, their similarities end there. The table shows the differences between these two structures:
| Key Point | Traditional Carports | Carport Solar Systems |
| Core function | Vehicle shelter only | Shelter + electricity generation |
| Structure type | Passive | Active energy infrastructure |
| Energy production | None | Daily solar power output |
| Long-term value | Fixed cost, no added return | Ongoing energy and financial benefits |
| Sustainability role | No sustainability impact | Supports renewable energy goals |
| Space utilisation | Takes up space | Turns parking into productive space |
| EV charging potential | Not supported | Easily integrated |
Common Types of Solar Panel Carports
Solar panel carports are available in a variety of configurations. This is to suit different parking requirements, space sizes, and design or functionality considerations. Choosing the right configuration is an important early decision for a solar carport installer, as it affects how efficiently the available land space is used and how easily the system can scale in the future.
Single Bay Solar Carports
The single-bay carport is a simple, solar-powered design commonly used in residential or small commercial settings. The solar carport primarily provides covered parking for one or a few vehicles, with a simple roof structure supported by two main pillars or columns. The solar carport in this design is smaller than the other types of solar carports. It is therefore easier to install a single bay solar carport.
Multi-Bay Solar Carports
In larger parking areas, multi-bay carports with solar are the preferred option. These are large parking structures designed to cover multiple rows of parking spaces. These areas could be large parking lots for institutions such as shopping centers, office complexes, campuses, and housing estates.
They are designed to have rows running parallel to each other or back-to-back cover that extends to a large area and generates more solar energy. This is also advantageous, as more modules or bays can be easily installed to increase energy production.
Cantilever-Style Solar Canopies
This approach represents a more contemporary look in solar panel carport systems. It has columns located on only one side of the structure, allowing the canopy to extend freely over the parking spaces. This type of design provides several benefits, including:
- More Parking Space: With columns only on one side of the solar panel carport, more parking space is available.
- Better Look: This design style offers an attractive aesthetic, especially in contemporary settings.
- More Design Flexibility: The carport can be better designed using either a single cantilever solar panel structure or a double cantilever structure. Singles are used in a narrow area, while their counterparts mainly use rows to create more parking spaces.
When choosing between any of these solar carport structures, the right configuration is essential to maximize the benefits of solar panel installation in residential driveways, parking lots, or other parking areas.
Where Carport Solar Is Commonly Used
Carport solar works best in places where parking space and daytime energy demand go hand in hand. From residential driveways to commercial car parks and public sites, these systems turn underused areas into productive energy-generating assets.
Residential Driveways
In residential areas, solar carports are primarily used where solar roof installation is not ideal or not feasible. Some houses have roofs that are too small, poorly aligned, or not structurally suitable for solar installation. In such areas, solar carports can be installed on driveways or in the parking areas of the respective houses.
Commercial Car Parks
Commercial car parks are among the most prominent and fastest-growing applications of carport solar. This is because shopping malls, supermarkets, hotels, and large retail outlets have large parking areas that are energy-inefficient. By installing solar-powered carports, these areas can be made more productive. At the same time, the shaded parking space provides greater comfort for customers, especially in hot climates, and enhances the overall experience of visiting the property.
Offices and Workplaces
Office buildings and workplaces are ideal locations for solar carports. Since office hours typically coincide with when solar energy production is at its peak, this reduces energy cost tremendously. Besides, solar carports in office environments promote sustainability initiatives and prepare the site for future requirements, such as electric vehicle charging stations, without requiring any modifications to the building roof.
Retail Centers, Campuses, and Public Spaces
Large institutions and public spaces are increasingly adopting carport solar technology. These include universities, hospitals, airports, government buildings, and public transportation centers. Basically, what ties all these buildings and institutions together is their need for energy efficiency. Carport solar technology foots this responsibility while providing a parking infrastructure.
Why Carport Solar Is Growing in Popularity
Carports with solar roof systems are increasingly being installed in residential, commercial, and public areas, not necessarily because they are new, but because it reflects a broader trend in how people use land, energy, and other resources.
Dual-Use Land Efficiency
The most important factor driving the growth of carport solar systems is efficient land use. Land is an essential resource, particularly in areas with increased parking demand. Carport solar systems are an evolution in how people think about maximizing available land resources. The growth of carport solar systems is particularly important in urban areas where space is limited, but resources are scarce.
Growing Electric Vehicle Adoption
The growing adoption of electric vehicles is driving the demand for carport solar systems, given the increasing need for charging stations. Parking lots now have the necessary infrastructure to provide the necessary protection and energy.
Rising Sustainability Goals
In the context of sustainability, demand from government bodies such as the Department of Climate Change, Energy, the Environment, and Water (DCCEEW) has been rising steadily over the past few years, driven by the need to reduce carbon emissions and provide an eco-friendly power source. Carport solar systems deliver the necessary benefits in this context, given that solar systems are the most eco-friendly energy source currently available on the market.
HShade and Energy Combined
Beyond energy generation, carport solar also offers benefits that promote productivity. For instance, parking cars in the shade prevents vehicles from overheating, while the solar panels ensure clean energy. This system makes the value of solar carports extend beyond energy generation.
