Solar power is growing faster than all other electricity sources in the U.S., representing 50% of the generation capacity installed in 2022. According to the latest Solar Market Insight Report, the U.S. installed 700,000 home solar systems last year, and the country now has enough solar capacity to meet the energy needs of 25 million homes. High-quality solar panels come with a 25-30 year product warranty, and homeowners paying high electric tariffs can achieve a payback period of less than six years.
One of the most important decisions when going solar is deciding where to install the photovoltaic (PV) array and inverter. Many homeowners choose roof-mounted systems, since they can take advantage of unused space. However, a solar carport is also a viable option: you get both a clean energy system and shaded parking areas in the same piece of land.
What Is a Solar Carport?
In simple terms, a solar carport is a canopy with photovoltaic panels that is installed above a parking area. Solar carports accomplish a dual function, providing a roof for your vehicles while generating electricity for your home. If you own an electric vehicle, a solar carport can also be combined with an EV charging station.
Solar carports work just like ground-mounted PV systems, since the racking structure is anchored directly to the ground in both cases. However, solar carports use a taller structure than ground mounting systems, since they must provide enough space to park vehicles.
Solar Carport vs. Traditional Solar Installation
Traditional solar installations take advantage of existing roof areas, and their racking system is attached directly to your roof structure. On the other hand, a solar carport is an independent structure anchored directly to the ground, which generates electricity while acting as a roof for your vehicles. Each type of system has advantages and disadvantages.
Benefits of a Solar Carport
A solar carport is slightly more expensive than a rooftop PV system of the same capacity, since you need a dedicated structure. However, solar carports also offer several benefits.
You can convert unproductive parking space into a renewable energy system.
Your vehicle is covered from rainfall, snow and UV rays.
Solar panels and inverters can be accessed more easily for cleaning, inspections and maintenance.
A solar carport can be designed with an orientation that maximizes the sunlight reaching your PV modules, increasing their electricity output.
