Terms of service
By using Sunwash you agree to these terms. Sunwash helps you find the best times to run appliances based on local sunshine. Last updated October 29, 2026.
What the service is
Sunwash is a free planning aid. Suggestions are based on weather forecasts from a third-party service, and forecasts can be wrong. Treat the results as guidance, not a guarantee of sunshine, savings or energy output.
Using it fairly
Please use the site for its intended purpose. Do not try to disrupt it, overload it, or access it in ways that are not provided through the site itself.
Availability and changes
The service is provided “as is” and may change, be interrupted or be withdrawn at any time. We may update these terms; continued use means you accept the updated version.
Liability
To the extent the law allows, Sunwash is not liable for losses arising from relying on its suggestions or from the service being unavailable. Nothing here limits rights you have under the law that cannot be waived.
