Terms of use

The basis on which this sizing tool is offered.

Last updated 11 September 2026

Sizing output is an estimate

Power & Sun provides this tool to help plan a hybrid solar system. Every result depends on the load information entered and on standard engineering assumptions. It is not a design, and it is not a substitute for a site survey.

Before installing anything

Confirm every figure against the manufacturer datasheets and your local wiring regulations. A qualified engineer must sign off the final design.

Acceptable use

Do not attempt to disrupt the service, access other users' records, or upload files containing malware.

Liability

To the extent the law allows, we are not liable for losses arising from reliance on an estimate produced by this tool.
