Rooftop Solar Racking

Unlike a conventional rooftop installation, where the photovoltaic panels are arranged flat on the roof, with limited space between them, a rooftop solar racking system requires a much larger footprint. That’s because each of these horizontal rows of panels needs to be directly connected to their respective electrical feeds. The amount of square footage required for your solar racking system depends on the number of units you plan to install, as well as your home’s roof and other constraints such as landscaping or parking. You can save considerable space by choosing a compact system design. For example, by stacking several modules vertically rather than horizontally, you can reduce your total footprint by 50 percent or more. This principle applies to almost any type of rooftop solar installation.

How much solar racking system do I need?

There are a lot of variables that go into figuring out how much solar racking system you need. Generally, the more modules you have, the more electricity they produce and the longer your solar panels will last. Consider your budget and energy needs before you decide on a rooftop solar racking system.
You should also consider your home’s roof’s physical constraints such as its slope or height restrictions. Many customers opt for a rooftop solar racking system because it can be installed without harming their home’s roof, which can sometimes be damaged by conventional installations with oversized panels. This is particularly true for customers living in hurricane-prone areas like parts of Florida or coastal regions of Texas and California, who may not take any chances with their roofs when facing potential damage from storms. The same applies to homeowners who want to install a compact rooftop solar racking system to save space but still generate enough power to power their homes.

Rooftop solar mounting options

Depending on your design requirements, there are three common mounting options for rooftop solar racking: tilt-up, tilt-down, and fixed.
For tilt-up designs, the panels are mounted to a roof surface that tilts toward the sun.
For tilt-down systems, the panels are mounted to a roof surface that tilts away from the sun.
Fixed designs have no moving parts and can be installed on any type of roof or building surface.

Solar panel sizing and choice of racking system

The first step in the solar panel sizing process is to determine how many solar panels you need. The size of the system you choose will depend on how much electricity it needs to generate. For example, a small home might require 20-24 panels, while a larger home might require 30-40 or even more. You’ll also have to consider whether or not your roof is suitable for solar mounting. In general, it’s best to go with a smaller number of panels if your roof is shaded by trees and other obstructions. This way, you won’t have to worry about shading or snow blocking the solar cells from receiving sunlight.

Decide on your inverter type

The next step is to decide on your inverter type. The power output of an inverter is typically measured in amps, kilowatts (kW), and volts (V) of output.
An important aspect of your rooftop solar installation is whether you want to integrate the solar racking system with your existing electrical wiring. If so, you need to consider whether or not the racking system can be connected directly to your electrical panel without having to install additional equipment or break up the panels from the roof’s surface. The size and number of panels should also be considered carefully when determining how much space the racking system will take up on your roof.

Calculate your additional racking requirements

If you’re interested in installing rooftop solar panels, the first step is to calculate your additional racking requirements. You need to figure out how many panels are necessary for your system, and where they should be mounted on your roof. If you have a larger home, this calculation is easy. For example, if you plan to install a 2-kilowatt (kW) solar rooftop system, it would take about one square meter of solar racking space per kW of installed capacity.

Additional considerations for compact rooftop installations

Whether you’re installing a conventional system or a compact system, take these considerations into account when looking for a reputable installer.
A reputable installer will understand the benefits and potential pitfalls of rooftop solar installation, and will have experience installing systems in your region. They should also be able to demonstrate in-house training and product knowledge by way of videos and manuals that are available online.
Another consideration is how long the company has been around. A reputable installer will be able to speak to their longevity, as well as show photos of installations they’ve completed that you can check out before hiring them. Another important factor is licensing and insurance. A reputable installer will be licensed through the appropriate governing body, such as the North Carolina state energy authority or the California Public Utilities Commission (CPUC). This ensures they’ve had the proper qualifications necessary to complete your installation safely.
Finally, it’s helpful if a reputable installation provider provides some level of warranty on their workmanship or materials. When it comes time for maintenance or repairs in the future, having this peace of mind can make all the difference between calling someone else versus dealing with an install that wasn’t properly done from the beginning.

Rooftop solar array dimensions

Most solar racking systems are installed on buildings of two to four floors. It is important to check for the height of your rooftop before choosing an array design.
The average rooftop solar racking system size is about 66×40 inches for the panel, about 1.25×1.6 inches for the frame, and each panel usually weighs about 42 pounds. This will vary, according to your home’s roof, the number of modules you choose, and whether you want a mono-crystalline or poly-crystalline panel configuration. If you want to install a larger array that covers most of a building’s roof, it might be better to use a single 100-watt panel at its maximum power output rather than three 60-watt panels in parallel.


Rooftop solar can be an excellent way to generate your own power and reduce your carbon footprint. But before getting started, there are a few things to keep in mind.
A rooftop solar racking system is one of the main components of your solar panel installation. The size and number of panels you need for your installation depends on a few different factors, including how many people will be living in your home and the amount of rooftop space you have available. To make sure you don’t end up with unsightly, inefficient racking on your roof, consider hiring a solar contractor to design your system for you.
