WE ARE CANADIAN NET METERING SPECIALISTS

Electricity consumers in Toronto and Ontario who produce some of their own power from a renewable resource may take advantage of the net metering initiative.

HOW DOES IT WORK?

Net metering allows you to send excess electricity you generate from renewable resources 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.

net-metering

Once you’re connected to the distribution system, your local distribution company will continue to read your meter just as they do now and then subtract the value of electricity you supply to the grid from the value of what you take from the grid. What you’ll see on your bill is the “net” difference between these two amounts. If you supply more power than what you take from the grid over the billing cycle, you’ll receive a credit toward future energy bills. The credit can be carried forward for up to 12 months. In order to see if Net Metering works for you, we are offering a Free Solar analysis. We are customizing your solar power system based on your year round electricity consumption. Click the “Get a free solar analysis” button and fill in your information, upload a copy of your Hydro bill and we’ll get back to you in no time. This way you can make an educated decision if solar in Toronto works or doesn’t work for you. We are here to help you make a good decision for yourself, as well as for the environment.

  Have had my system installed for 6 months now, and though production vs. estimate should only really be judged after a couple of years, so far so good.  It was great working with John and Cosmin, they were always willing to answer my many questions.  Overall process took a little longer than anticipated, but with Covid, supply chain and finding worker issues, that really should be expected.
Provided information and installation were excellently done, and have had no issues so far.   I feel secure in dealing with a company that has been around so long, and not one of the many fly-by-night companies that seem to be knocking on doors recently.
Keep up the good work guys.

  We had our solar panels installed in June 2020.  The entire process, from preparing a detailed quote, answering questions, completing paperwork to installation was done professionally and in coherence with the the Covid-19 restrictions at the time.

The installer, Cosmin, was a pleasure to work with.  He answered any questions I had and effectively dealt with a shadow issue with a chimney shortly after installation.  I am confident that should there be any issues that arise that Terawatt will be there to back up their product and installation.

Finally, in terms of electricity generation and cost offset, everything seems to be 'paying-off' as predicted, if not better.  I continue to be satisfied with the work done by Terawatt and highly recommend them for full service residential solar panel installation.  Paul W, Oshawa
