Frequently Asked Questions

Most electrical work in Ontario requires an ESA permit — including panel upgrades, new circuits, EV charger installations, and solar system connections. Koltrux Inc. handles the permit application and coordinates the ESA inspection on your behalf.

An ESA inspector visits the property to verify that the electrical work meets the Ontario Electrical Safety Code. We schedule and attend the inspection, and any required corrections are addressed promptly at no extra cost.

Permit timelines vary by project type and municipality, but most residential permits are issued within a few business days. We factor permit lead times into your project schedule from the start.

Common signs include frequently tripping breakers, a fuse box instead of a breaker panel, a 60A or 100A service that can't support modern appliances, or plans to add an EV charger or solar system. We can assess your current panel and recommend the right upgrade.

Most residential panel upgrades are completed in one day. The power will be off for a portion of the day while the work is done. We coordinate with the utility for any required disconnection.

Most modern homes benefit from a 200A service. If you have a large home, electric heating, an EV charger, and solar, a 400A service may be appropriate. We perform a load calculation to recommend the right size for your needs.

Net metering allows you to send excess solar energy back to the grid and receive a credit on your electricity bill. Koltrux Inc. handles the net metering application with your local utility as part of the solar installation.

A Level 2 charger uses a 240V circuit (like a dryer outlet) and charges most electric vehicles 5–10 times faster than a standard 120V outlet. It's the recommended home charging solution for daily use.

It depends on your current panel capacity and existing loads. We assess your panel before any installation and will recommend an upgrade if needed to safely support the new equipment.

Our O&M services cover scheduled preventive maintenance, IV curve testing, thermal imaging, inverter inspection, module cleaning, string and DC wiring checks, remote monitoring, fault diagnosis, and corrective maintenance and repairs.

We typically recommend at least one full preventive maintenance visit per year, with additional inspections after severe weather events. Remote monitoring allows us to identify and respond to faults between scheduled visits.

Yes. We provide operations and maintenance services for commercial solar assets regardless of who installed them. We begin with a baseline inspection and performance assessment before establishing a maintenance schedule.
