We used an 80 watt crystalline panel alongside our 45 watt amorphous silicon panel to see what the effective power output over the course of one average day with minor shadowing would be for each. Interestingly the lower wattage “less efficient” PowerFilm panel produced more power to the battery under the same conditions as the crystalline panel. Showing that the panel efficiency isn’t the most important consideration when rating solar panel effectiveness.
