Important:
Final module selection always depends on what is approved in your state for Residential or Commercial or Industrial projects, what qualifies under current IRA/OBBBA and domestic-content guidance, and what is available in the supply chain at the time of your project. When needed, Sunguru Energy will substitute a similar or better Tier-1 panel with comparable efficiency, production and compliance profile.
Compliance & Incentive Note
Many of the panels above (especially Qcells Q.TRON AC, Silfab, and Sirius PV models) are designed or marketed to support domestic-content eligibility and/or U.S. manufacturing preferences under the Inflation Reduction Act and related guidance, but final qualification for tax credits and bonus credits is determined by the IRS rules, Treasury guidance, and your tax situation.
