For some panels, their high power output rating is due to their larger physical size rather than their higher efficiency or technological superiority. For example, if the solar panel is rated at 175 watts and the maximum power voltage, Vmp, is given as 23.6 … But SunPower's panels are designed to minimize these losses in energy production. Most solar panels are built with "anti-reflective glass," which means once light enters the panel it will bounce back into the solar cell to harness as much power as possible. 40 amp-hours per day = 30 amp-hours per panel per day * X panels. SunPower panels harvest more infrared and more ultraviolet light than conventional solar panels. Solar panels usually range in wattage output from around 250 watts to 400 watts, but some panels exceed the 400 watt mark.
