Solar PV Installation
Grid-tied solar PV system design and installation, including panel mounting, inverter wiring, and utility interconnection.
Overview
Solar PV installation is as much an electrical project as a roofing one: the panels only pay off if the wiring, inverter, and interconnection behind them are sized and installed correctly. We handle the electrical side of residential and commercial solar installations, DC wiring from the panels to the inverter, inverter and rapid-shutdown installation, the dedicated solar breaker and backfeed connection at your panel, and coordination of the utility interconnection and net metering application, for homes and businesses across Toronto and the GTA. Whether you’re adding panels to an existing roof-mount racking system or wiring a new array from scratch, every connection is sized to code and inspected before it’s energized.

Why It Matters
A solar array that’s mounted well but wired poorly is where most preventable problems show up: an inverter that isn’t sized to the array’s actual output, a backfeed breaker that exceeds your panel’s busbar rating, or DC wiring runs that weren’t protected against the specific fire and arc-fault risks that come with a live DC source on your roof. Interconnection rules matter just as much, most utilities require documented net metering approval and a compliant rapid-shutdown system before an array can be turned on, and getting this wrong means delays or a system that fails inspection. We size the interconnection to your actual panel capacity and existing loads so the array integrates cleanly instead of becoming the reason your service needs an upgrade.
How Solar PV Installation Works
- 1
Site & panel assessment
We review your roof or ground-mount plan, existing panel capacity, and busbar rating to confirm what the electrical side of the system needs.
- 2
System design & permitting
We size the inverter, DC wiring, and backfeed breaker to the array, then pull the ESA permit and prepare the utility interconnection and net metering application.
- 3
Wiring & inverter installation
We install the DC wiring, rapid-shutdown devices, inverter, and the dedicated breaker and backfeed connection at your electrical panel.
- 4
Interconnection, inspection & commissioning
We coordinate ESA inspection and utility sign-off, then commission the system and confirm it’s producing and net metering correctly before we leave.
What Affects the Cost
Cost depends on system size and inverter type (string vs. microinverters), whether your existing panel has enough busbar capacity for the backfeed breaker or needs an upgrade, the distance and routing between the array and your panel, and utility interconnection requirements in your area.

Frequently Asked Questions
- Do you install the solar panels themselves or just the electrical work?
- We handle the electrical side of the installation, DC wiring, inverter, rapid shutdown, and the panel connection, and coordinate with your racking/roofing installer on the mounting and array layout.
- Will my electrical panel need an upgrade for solar?
- It depends on your panel’s busbar rating and existing load. We check whether it has enough capacity for the backfeed breaker as-is or whether a panel upgrade is needed alongside the solar installation.
- What is net metering and do you handle the application?
- Net metering lets excess power your system produces feed back to the grid for credit. We coordinate the utility interconnection and net metering application as part of the installation.
- Is a permit required for solar PV installation?
- Yes, solar installations require an ESA permit and inspection, along with utility interconnection approval, both of which we handle as part of the job.
- String inverter or microinverters, which do you install?
- We install both, and size the choice to your roof’s shading, layout, and system size rather than defaulting to one option.
- How much does solar PV installation cost?
- Cost depends on system size, inverter type, whether your panel needs a busbar or service upgrade, and utility interconnection requirements. We provide a clear quote after assessing your roof and panel.
