Terms & Conditions
Eligibility: This offer is available to customers purchasing a new solar or solar + battery system installation. Additions to an existing system qualify if they include a battery, or a minimum of 8 panels. Panel-only additions of fewer than 8 panels do not qualify.
Deadline: Offer must be claimed by submitting the form above by 11:59 PM on May 31, 2026.
Eligible Counties: This offer is only valid for properties located in Cache, Box Elder, Rich, or Weber County, Utah.
Quote Requirements: The comparison quote must be from a licensed and insured solar/electrical contractor, dated July 1, 2025 or later, and for the same property.
Equipment Match: Comparison must be for equipment equivalent to what Green Box Solar installs (tier-one panels, code compliant/UL certified inverters and batteries, and components of identical or comparable quality and specifications). If you're unsure, just ask. We want your business and we want you to be able to take advantage of this offer.
How It Works: If we cannot beat your existing solar proposal on price for a comparable system, you receive a free EcoFlow DELTA 3 Plus. If you choose to go with Green Box Solar for a new solar or solar + battery system installation, the power station is included free with your install. Price comparison is based on total system price before tax credits, rebates, or other incentives.
Limit: One offer per household. Cannot be combined with other promotions.
Additional Details
"Equivalent equipment" means tier-one solar panels, inverters, and components comparable to what Green Box Solar installs. Used, refurbished, secondhand, or lower-tier equipment does not qualify.
Green Box Solar reserves the right to verify the authenticity of competing quotes and the licensure/insurance status of the quoting contractor.
The EcoFlow DELTA 3 Plus will be delivered upon completion of the in-home consultation (if we can't beat your quote) or upon completion of installation (if you choose Green Box Solar).
