Solar systems are comprised of a few components, and it's important to properly install and maintain your solar panels. ROI’s team of professionals are trained to handle all rooftop solar types with safety at the forefront.


Building science is a field of knowledge that draws upon physics, chemistry, engineering, architecture, and the life sciences. Understanding the physical behavior of the building as a system and how this impacts energy efficiency, durability, comfort, and indoor air quality is essential to innovating high-performance buildings. Modern building science attempts to work with models of the building as a system, and to apply empirical techniques to the effective solution of design problems.


Renovation, retrofit, and refurbishment of existing buildings represent an opportunity to upgrade the energy performance of commercial building assets for their ongoing life. Often retrofit involves modifications to existing commercial buildings that may improve energy efficiency or decrease energy demand. In addition, retrofits are often used as an opportune time to install distributed generation to a building. Energy-efficiency retrofits can reduce operational costs, particularly in older buildings, as well as help to attract tenants and gain a market edge.

Sustainable Energy

Commercial Solar

Every kilowatt-hour of energy your solar PV panels produce is one kilowatt-hour you don’t have to buy from your energy company. At ROI Energy, we can custom-design a commercial solar system to meet your goals, reducing your monthly energy bills.


Residential Solar

For decades, electricity bills have been an inevitable expense. But with residential solar panels from ROI Energy, North Carolina homeowners can turn that inevitable expense into a lifelong investment.
