How this tool works
Cost = kW × equipment cost per kW + installation + other costs. Pre-tax price = cost / (1 − target gross margin). Tax applies to that price.
What should I check before using the result?
Indicative quotation only. Requires site survey, roof/structural and electrical assessment, component specification and verified local tax/subsidy rules. No generation guarantee.
Do free tools require an account?
No. Public UtilityHub tools open without an account. An account is required only when you want a workspace to save records, collaborate with a team or use paid product features.
Are the public tools really free?
Yes. The tools listed in the public tools directory are free to use. They do not start a subscription and do not ask for a card.
Are my files uploaded to UtilityHub?
Image and PDF pages state how each tool processes files. Where a page says browser processing, the work happens on your device. Always check the privacy note on the specific tool before adding a sensitive file.
Should I verify a downloaded result?
Yes. Open every downloaded file and confirm its dimensions, size, legibility and destination requirements. UtilityHub helps prepare a result but cannot verify the current rules of every external form or service.
Nothing is added to your business workspace unless you choose to continue there.
