Net metering allows you to send excess electricity you generate from your solar panels to the distribution system for a credit toward your energy costs. In essence, it’s a “trade” of electricity you supply against electricity you consume. The Net Metering program gives GTA homeowners the power to better manage energy costs. When you’re producing more renewable electricity than you can use, Hydro will take the surplus supply back to the grid. In return, the utility will give you a credit on your bill to help pay for those times when you’re not generating enough power and drawing from the grid helping expedite the ROI for your solar system investment.

Offset Your Energy Bill: Net Metering in Ontario gives you the opportunity to use solar energy to power your home while offsetting your electricity bill.
Receive Electricity Credits : If the amount of electricity produced exceeds the amount required to power your home, you can give the remaining amount back to your local provider in exchange for electricity credits that can be deducted from future usage.

Homeowners trust Terawatt Solar knowing we provide strong references from clients we have served for over a decade. Our clients will tell you that we continue to monitor and support their solar power installation long after their system is commissioned. We are currently offering eight years warranty on our installation labour.

We take care of everything to do with your solar. We stock the product, supply, manage, install, & inspect to ensure you are getting the best service possible.

With our years of experience and thousands of residential solar systems sold, we were able to create a strict quality control program that assures every installation is done to the highest standards.

Since the Government of Ontario ended all incentives for renewable energies, TeraWatt Solar has created our very own “Neighbourhood Advantage” program. Our unique approach allows users to lock in reduced electricity rates for 25 years, offering Ontario homeowners price security for electricity regardless of increases to the Hydro rates
