By downloading or using FieldWatt, you agree to these terms.
FieldWatt is a reference and planning aid for qualified solar professionals. It is not a substitute for the National Electrical Code (including Articles 690 and 691), NFPA 70E, the site's PE stamped drawings, the authority having jurisdiction, site procedures, or manufacturer manuals. Where FieldWatt and any of those disagree, they govern, not the app.
Work on energized equipment, medium voltage systems, and safety critical faults (including arc, ground, and insulation faults) must be performed by qualified persons under the applicable safety program. FieldWatt never advises resetting safety faults or overriding plant controls, and nothing in the app authorizes anyone to perform work they are not qualified and authorized to do.
Calculator outputs, reference entries, and production numbers are planning estimates and curated summaries provided in good faith without warranty of accuracy or completeness. A qualified person must verify all results against the governing documents before acting on them. You assume all risk arising from use of the app.
FieldWatt Pro is offered as a monthly subscription, an annual subscription (with a free trial for first time subscribers), or a one time lifetime unlock, billed through your Apple account. Subscriptions renew automatically until cancelled in your Apple account settings at least 24 hours before the period ends. Refunds are handled by Apple under their standard policies.
Forms, photos, signatures, receipts, and PDFs you create belong to you and stay on your device. You are responsible for their contents and for where you choose to send them.
To the maximum extent permitted by law, ThrasherApps and Chris Thrasher are not liable for any indirect, incidental, consequential, or special damages, or for injury, equipment damage, production loss, or code violations arising from use of or reliance on the app.
These terms may be updated; the date above reflects the current version. Continued use after changes means acceptance.
