Solar Design & Installation

At VCT Group we do more than construct and install solar. We are advancing state of the art solar design through innovative engineering. Our design philosophy is that solar is for everyone. Solar needs to seamlessly blend into our lives. We custom design, engineer, and build for more than basic utility– we bring the power of solar down to earth.

We design systems at all scales for commercial use. Rooftop solar has led the way for the past decade and continues to drive excellent performance and value. We see the next decade and beyond as the rise of solar canopies. Solar that is accessible in the urban and pedestrian environment.

Our solar carports transform space into an uplifting, approachable and usable destination. Designed with snow and rain management as standard, they provide UV protection and humanize solar power. Upgrade your parking lot with premium, protected spaces.

Operations & Maintenance

We’re committed to performance. Our solar operations and maintenance programs are designed to ensure peak system performance to maximize electricity generation, optimize financial return, and protect your investment.

A majority of mid-sized systems develop small, undetected losses within 3 to 4 years. These issues compound over time, degrading your system’s performance, and lead to significant losses if not detected.

Actively monitoring to identify and correct these small operational issues is the best way to maintain a healthy, efficient system. VCT Group’s solar operations and maintenance services combine internet-based system monitoring with a suite of maintenance procedures.

After installation, you can be confident that your system is in good hands and will maintain its performance for its lifetime of 25 years and beyond.

O&M Subscription Programs

VCT Group offers a suite of O&M subscription packages for several system sizes. 

Remote Monitoring


Daily Monitoring

Your PV system is monitored daily by an active service that reviews site level faults and data output provided by solar PV system hardware.


Fault Notification

Critical fault notifications are pushed to the customer and VCT Group. Examples of critical faults include power loss, downed inverters, and inverter underperformance.


Sensor Packages

System add-ons like snow cameras, irradiance sensors, thermometers and wind speed detectors can assist in remote diagnosis of issues.


Weekly Performance Review

Our monitoring team and platform algorithms analyze system performance and identify underperforming system components.


Monthly and Annual Reports

Recieve regular reports on month-over-month performance, daily production values, forecast predictions, and irradiance data.


Response Time Priority

VCT Group optimizes our fleet to ensure outages are reduced to minimal impact.

Solar Performance Diagnostics

While generally reliable, sometimes solar panels develop performance problems. All of our systems are backed by more than 10 years of ownership experience, and we stand behind every installation. We’re committed to ensuring solar PV systems perform at their best. 

VCT Group continues to expand our monitoring and solar diagnostics tools to help us get systems performing at their absolute best. In addition to our active monitoring program, we use a suite of solar diagnostic tools to help us identify underperforming elements in solar arrays.

Remote monitoring can help to diagnose issues, but sometimes further diagnostics and testing is required in the field. Here’s a few of the diagnostic tools we use to enhance solar PV performance:

I-V Curve Tracing

I-V Curve Tracing is a fast, reliable, and comprehensive way to efficiently identify and diagnose performance issues in PV systems.

For each string in a photovoltaic array, an I-V Curve Tracer measures current and power as a function of voltage. Comparing voltage measurements of a range of electrical loads connected to a string are compared to expected results. By analyzing the shape of the curve, this can identify problem-causing elements in the string, such as which module, connector, or length of wire could be causing performance issues.

When a system seems to be underperforming, I-V Curve Tracing is an efficient method of troubleshooting and narrowing down potential issues.


Infrared Analysis

The cells within typical solar panels have an efficiency of approximately 20%. Simplified, this means that 20% of the light energy that hits the cell is converted to electricity, while the other 80% remains as heat. When a cell in a solar PV panel is malfunctioning or failing to properly convert sun energy to electricity, it gets hotter than other cells in a panel. Infrared analysis is able to detect these temperature variations, and point to where problems may exist within the panel. The same analysis can be done to cables and other electrical elements within the system, identifying heat build up and indicating where there may be performance problems.

When the conditions are right, infrared analysis can be performed on a system while it is in operation, without unplugging any components or shutting the system down.


Electroluminescent Testing

The cells inside solar panels are brittle, and can fracture or be broken from impacts or from mishandling. These fractures can be difficult to identify without special equipment. Electroluminescent testing works by running the solar panel in reverse; when applying current to a solar panel, normal functioning cells will emit very small amounts of light outside the visible spectrum. Where circuits and cells are broken, no light is emitted, as can be seen in the cracks in the accompanying image. Electroluminescent testing is an alternative to infrared analysis, but provides much more detail as to what problems may exist within a panel, and doesn’t require the panel to be in operation under ideal conditions.

We provide expert advice on all financial and regulatory aspects of solar power. The energy program landscape is constantly evolving and we’re here to provide experienced services to ensure that the financial performance of your system works for you. We can simplify the process of installing solar, from the initial site design to energizing the system, and beyond.

The Ontario energy market for solar was originally based on a Feed-in-Tariff (FIT) model, ensuring a guaranteed purchase price for the electricity you generated and fed into the provincial grid. The model has now switched to Net Metering, where the difference between your energy usage and power generation results in a credit for your surplus electricity.

Talk with us today about any questions you have about incorporating solar into your energy mix.

Powering everyone.
