We had my system installed 2 months now. It was a great working with cosmin and team, they are always available to answers my questions. I am really happy with their service. Good job guys keep it up.

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.

Update my solar system is now installed and working they did a great job. Everything was installed this month as they said it would.

Cosmin and his team did a fantastic job installing the Solar system. Cosmin did a great job of keeping me in the loop and managing the process required to get all the approvals needed to everything installed and commissioned.

Great service from start to finish and reasonable too. Very happy to have done business with Terawatt Solar. Thanks a million.

Great solar installation from the team at Terawatt Solar. Thank you!

Had a great experience with this company. They where very professional and timely from start to end. I highly recommend this company if your thinking of doing solar.

After quoting three companies, Terawatt presented not only the best economical solution, but the best brands and high-tech Canadian equipment. If you wanna go solar, go Terawatt. They are the best! My PV system was installed with no issues and is working awesomely! These guys you can trust! Thank you for your business.

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
