Estimates only

Everything on this site is a modelled estimate for general information. It is not a quote, not an offer, and not financial, tax, engineering or legal advice. Actual system costs, production, savings and payback will differ — sometimes substantially — based on your roof's condition, your utility's tariffs and net metering rules, equipment chosen, installer pricing and local incentives.

Get professional advice

Always obtain quotes from licensed installers and, where relevant, advice from a qualified tax professional before making a purchase decision.

Data sources

Rooftop data comes from the Google Solar API and reflects Google's imagery, which may be several years old and may not reflect recent changes to a building or its surroundings. Electricity rates are state or provincial averages, not your specific tariff.

No warranty

This site is provided "as is" without warranties of any kind. We do not warrant that estimates are accurate, complete or current.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any loss arising from reliance on information published here.

Acceptable use

Automated scraping or bulk querying of the roof analysis endpoint is not permitted. Rate limits apply.
