Installation Process

Our Solar System Installation Method

United Solar Group Corporation will custom design your solar energy system and install it for long-term success. From design to completion, you’ll be pleased with our efficient work.

  • Design – our engineers will design a custom system for your building. We’ll send the detailed plans to you and our technical department to begin the work.
  • Permits – we provide the structural and electrical plans to local officials so all the appropriate paperwork and permits are completed.
  • Installation – after the permits are approved, we’ll schedule a time for our professional crew to begin work on modules and racking system installation 
  • Inspection – when our installation is completed, we’ll schedule a time for local officials to inspect our system and ensure its up to code.
  • Interconnecting – after the solar PV system passes the inspection, your utility company is notified. In a few days, they will come to your property and install a net meter that connects the solar system to the grid.
  • Your roof’s design will influence the cost-effectiveness of your solar panels. For example, you want a roof with plenty of surface area that does not feature a lot of skylights, chimneys, or other roof features so that panels can be installed without hindrance. The condition of the roof is also a major factor when installing a solar system. It is recommended that a roof older than 5 years be evaluated prior to installation.

Types of Mounting Systems

Integral mounting systems involve the integration of solar modules directly into the roofing or exterior structure of a building. These innovative systems are often known as building-integrated photovoltaics (BIPV), reflecting their seamless incorporation into the architecture.
Standoff mounting systems, also known as flush mounting, utilizes standoffs affixed to the roof to provide support for rails, upon which photovoltaic (PV) modules are mounted. This is the most common method for residential installations.
Ballasted mounting systems are frequently used in expansive flat roof commercial ventures. These systems require meticulous engineering to account for both the structural load on the roof and the specific ballast requirements. To address concerns such as seismic activity or heightened wind conditions, additional measures like roof tethers are often incorporated to bolster the effectiveness of the ballast.

Rack mounting systems are commonly used for stationary systems, particularly in ground-level installations and on flat rooftops. This approach is prevalent in large-scale commercial projects or utility-scale arrays due to its suitability for such applications.


Pole mounting systems involve the utilization of pre-fabricated racks affixed either atop or alongside a steel pole. This method is frequently chosen for off-grid residential PV systems. When determining the appropriate mounting system for the array, referencing span tables from various sources can assist in assessing the load-bearing capacities of roof trusses or beams.
