    It’s worth something! It shows Aptera’s been consistent with giving out the 700 watt number (for full solar package). The “representative” array that has been on someone’s roof likely had the SunPower IBC cells.

    The most efficient solar panel available in the recent past/today (certain models of SunPower/Maxeon) calculates out to having individual cells (125 mm x 125 mm) at just about 3.8 watts each. These factory made panels are incredibly well made (~25 year power warranty) and, more importantly, have ALL their cells pointed nearly identically (normal) to the great ball-o-fire in the sky. Aptera’s nominally 180 cells are not and hence simply will not deliver 700 watts even under Standard Test Conditions let alone real conditions (with the possible exception for brief periods when it’s really cold out and there are “edge of cloud” episodes!)
