Hi guys! I'm in the VIIth standard, and am building a solar powered RC plane. But however, I'll need help to figure out... One solar panel of a calculator creates 1.53 volts of power under a dim CFL. If photovoltaic cells are influenced by the lumen count, how much can it generate under bright sunlight (5,000-10,000 lux)? How much power is produced per lumen by a photovoltaic cell? A final question: how many volts does two props require, and accordingly how many calculator solar cells am I to place on the wing if it were to run under even a CFL (most props require 9 volts of power each, so I guess 1.53 volts x 10 panels will give me the required power)? Thank you for helping.
