Last updated 2026. This page explains what personal information Terawatt Solar collects, why, and how we handle it.
Terawatt Solar ("we," "us," "our") is a residential and commercial solar installation company based at 7030 Woodbine Ave, Suite 500, Markham, Ontario, L3T 6G2. This policy applies to information collected through www.terawattsolar.ca, our free solar assessment survey, our contact form, our solar price calculator, and any related phone or email communication.
Depending on how you interact with us, we may collect: your name, email address, phone number, property address or postal code, and details about your home's electricity usage, roof type, and ownership status, which you provide directly through our contact form, our multi-step solar assessment survey, or the solar price calculator. If you call or email us, we retain the contact details and any information you choose to share during that conversation.
Our survey also uses TrustedForm, a third-party consent-documentation service, to generate a timestamped record confirming that a form was submitted and that applicable consent language was displayed, which helps us demonstrate compliant consent practices. We also collect standard technical information automatically, such as the page you came from, UTM campaign parameters, and submission timestamps, which help us understand which marketing efforts are working.
We use the information you provide to respond to your inquiry, prepare a solar system design and price estimate, schedule a site assessment, manage utility interconnection and permitting paperwork on your behalf if you become a customer, and follow up by phone, text, or email about your request. Marketing campaign data (such as UTM parameters) helps us measure which advertising channels are effective, so we can keep our costs down and continue offering competitive pricing.
If you submit a form on our site, you may be contacted by phone, text message, or email, including through automated dialing or messaging systems, regarding your solar inquiry. Consent to be contacted this way is not a condition of purchasing any product or service from us. You can ask to stop receiving texts at any time by replying "STOP" to a text message, or by contacting us directly using the information below.
We do not sell your personal information. We share information only with service providers who help us operate our business, such as our customer relationship management platform (used to track and respond to leads), TrustedForm (for consent documentation), and, where applicable, local utilities and municipal permitting offices as a necessary part of installing and interconnecting your solar system. We may also disclose information if required to do so by law.
We use reasonable administrative and technical safeguards to protect the personal information we collect, appropriate to the sensitivity of that information. No method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security, but we take data protection seriously and limit access to personal information to staff who need it to do their jobs.
You can ask us to access, correct, or delete the personal information we hold about you, or to stop contacting you, at any time by emailing [email protected] or calling (877) 648-3323. We will respond in good faith and within a reasonable time.
We may update this policy from time to time to reflect changes in our practices or for legal and regulatory reasons. The "last updated" date at the top of this page reflects the most recent revision.
Questions about this policy or how we handle your information can be directed to Terawatt Solar, 7030 Woodbine Ave, Suite 500, Markham, ON L3T 6G2, [email protected], (877) 648-3323. See also our terms and conditions.
