A cheap way to put 400 W on an RV, boat or shed roof where smaller panels fit better than large ones. Buyers who want full published specs and a stated warranty pay a little more for HQST’s 400 W pair.
Amazon $229.59A large-panel pair for a cabin, shed or ground-mount array with a high-voltage MPPT controller. Too big and too high-voltage for most van and small RV setups.
Amazon $599.99 Renogy $599.99A frameless dual-glass large panel for home rooftop, shed or ground-mount buyers who want edges that shed dirt and snow. The missing electrical specs make it a harder buy than framed panels with full data sheets.
