Last updated 2026. Please read these terms before using our website or requesting a solar assessment.
By accessing or using www.terawattsolar.ca, including our contact form, free solar assessment survey, or solar price calculator, you agree to these terms and conditions. If you do not agree, please do not use this website.
The solar price calculator and any system size, cost, savings, or production figures shown on this website are estimates for general informational purposes only. They are based on assumptions about typical Ontario conditions, including roof orientation, shading, electricity rates, and equipment pricing, and are not a binding quote, offer, or guarantee of actual cost, savings, or energy production. Actual figures for your property depend on a site-specific assessment and may differ from any online estimate. A written proposal from Terawatt Solar following a site assessment supersedes any online estimate.
Content on this website, including blog articles and incentive program summaries, is provided for general informational purposes and does not constitute financial, tax, legal, or engineering advice. Incentive and rebate programs referenced on this site (such as Ontario's Home Renovation Savings Program) are subject to change by the governing authority, and we encourage you to confirm current program details before making a decision based on them.
You agree to use this website only for lawful purposes and not to submit false or misleading information through our forms, survey, or calculator. We may refuse service, remove content, or restrict access at our discretion, including in cases of suspected misuse, fraud, or abuse of our tools.
The text, images, logos, and design of this website are owned by Terawatt Solar or used with permission, and may not be copied, reproduced, or distributed without our prior written consent, except for your own personal, non-commercial reference.
This website may link to or reference third-party websites, utilities, or government program pages that we do not control. We are not responsible for the content, accuracy, or availability of third-party sites. Our survey uses TrustedForm, a third-party consent-documentation service; use of our survey is also subject to that service's own terms.
To the extent permitted by law, Terawatt Solar is not liable for any indirect, incidental, or consequential damages arising from your use of this website or reliance on any estimate, calculator result, or content provided here. Nothing in these terms limits any liability that cannot be excluded under Ontario or Canadian law.
These terms are governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein, without regard to conflict of law principles.
We may update these terms from time to time. Continued use of this website after changes are posted constitutes acceptance of the revised terms. The "last updated" date at the top of this page reflects the most recent revision.
Questions about these terms can be directed to Terawatt Solar, 7030 Woodbine Ave, Suite 500, Markham, ON L3T 6G2, [email protected], (877) 648-3323. See also our privacy policy.
