Rooftop Commercial Solar Installation Step By Step Guide

In a rooftop commercial solar installation step, what happens? How much does it cost? How much time does it take? Most significantly, can rooftop commercial solar panels help your company save money?

First and foremost, it is important to note that each project is unique. Please contact your Solar salesman for data specific to your situation (insert Link).

Let’s get there.

Investing in solar energy for your company is a smart and sound financial move. After all, the financial benefits and beneficial environmental impact of reducing your energy costs and carbon footprint by producing your clean power will be felt for decades. You’ll also join the ranks of successful firms that have switched to solar energy, making your company more appealing to present and potential workers.

Time-limited tax incentives might help your organization switch to solar more economically by easing the transition. The Federal Investment Tax Credit is one of the most appealing perks. Still, the present rate of 26 percent will expire after 2022, so get started on your solar project as soon as possible to earn the greatest credit.

It’s only natural that once you’ve decided to install a rooftop commercial solar power system in your business, you’ll want to have it done as soon as possible to start reaping the advantages right away. However, the solar transition process may change over time based on the type and scale of the the system you install and the regulatory requirements of the jurisdiction in which you operate. Most rooftop business solar projects follow a five-step procedure, regardless of the solar strategy you pick.

Rooftop Commercial Solar Installation Step:

  1. Assessment of the Site

Site assessment is the initial step in all rooftop commercial solar installations. This first site evaluation serves as the foundation for solar system building blocks and installation plans. This stage entails the following:

  • Verify that you have the legal authority to construct a solar power plant on the site.
  • Determine the location and method of your solar power plant’s grid connection.
  • Property appraisal includes color analysis, structural evaluations, and topographical and geological studies.


1. Design of the System

At this time, the design and installation plans have been finalized. You will receive a design drawing showing how the panels will be installed to maximize sunlight and construct the structure. Depending on your demands, the design may show you the roof, floor, or carports. The design and installation plans have been completed at this time. 

2. Construction

The construction procedure may differ depending on the project type and system size. Smaller roofing systems can take as little as two weeks to install, while bigger, more intricate systems might take months.

While well-thought-out planning will minimize disruptions to routine operations, you should still be prepared for alternate parking locations and temporary power outages, depending on the nature of your organization and the system’s size. To minimize inconvenience, most experienced solar installers have devised ingenious solutions. It is critical to select a reputable and skilled installation in this regard.

3. Commissioning

Following the completion of construction, the next and last stage is commissioning. When your solar installer certifies that your solar system was built according to design, the utility will authorize you to connect and run your solar power system to the local electricity grid. Congratulations, you are now generating your renewable energy!

4. Maintenance and operation of the system (O&M)

As with everything else, appropriate care and maintenance will extend the life of your solar energy system while also ensuring optimal efficiency and energy output. The amount of your organization’s engagement in O&M should be specified in your contract.

Choose a solar design and installation company that has demonstrated O&M resources and a track record of providing long-term assistance. Basic yearly inspections and warranty repairs, performance monitoring, and, in certain circumstances, periodic cleaning are all included in the top O&M packages.

How are Commercial Solar systems put on rooftops?

There are two basic methods for installing solar systems on commercial building roofs:

Weighted Shelving – Secures solar systems to a flat roof with substantial weights, generally concrete blocks.

Some hybrid ballast systems employ a mix of ballast and roof penetrating anchors to secure the roof system. The number of passes these systems can make through the roof is generally determined by the roof’s ballast capacity and how much extra PV system support is required to match the wind load conditions.

Advantages :

  • Easy to install; requires little or no roof
  • Ballast system of photovoltaic racks

  • penetration; hybrid ballast systems require less weight
  • these fully weighted systems


  • Applies to flat roofs only.
  • capable of withstanding the weight of the ballast; some jurisdictions restrict the use of fully weighted systems; May
  • require additional estimates of wind load; hybrid ballast systems have an increased risk of roof collapse
  • leaking from a broken roof

Attached Shelving – Uses equipment to penetrate the roof.

For mounting photovoltaic systems on any roof. There are

many hanging shelving systems for various

applications, as shown in the images below. in

The number of roof penetrations required will depend on

roof construction, photovoltaic system design and local construction


  • Benefits: Can be used on pitched and flat roofs.

in more jurisdictions than ballast systems

  • Cons: Maybe more difficult to install than weighted systems; defective roof penetrations can reduce

weatherproof roof integrity

What is the impact of installing a solar photovoltaic system on my roof?

If properly placed, solar arrays on roofs should have no negative impact on structures. The Key of the Building Owner Concerns about photovoltaic systems typically involves how they can affect the roof’s integrity (i.e., the possibility of water intrusion or other damage), roof warranties, building permits, and company operations. However, these hazards can be managed or removed, as demonstrated below. The entire roof is covered in solar panels.

Solar panel installers with a good reputation must install the systems.

Although PV installers are not needed to have national certifications, many are Nord certified by the American Board of Certified Energy Professionals (NABSEP)

As you can see, several factors go into the rooftop commercial solar installation. Time is running out if you want to take advantage of valuable tax benefits. As previously stated, the 26 percent federal investment tax credit will be phased off in 2022. Installers’ schedules for this year are already filling up due to the extraordinary demand for solar electricity, so we advise you to get started on your project as soon as possible to take advantage of this tax benefit for your business.
