I’m pretty sure you have a typo or three. Your “for every degree increase in temperature above 77F degrees, a solar panel can lose 10-25 percent of it’s efficiency” is not correct (for practically all crystalline cell panels). A SunPower/Maxeon panel might lose 15% (relative) of it’s efficiency when it goes from a cell temperature of 25 C to 75 C. That’s equivalent to taking a 700 watt rated array to just under 600 watts. A 75 C solar cell, by the way, is likely only under the hottest, most stagnant conditions.
