Can a honeycomb solar power calculation Buld a flashlight?
Trinidad to do a project for school What size HONEYCOMB SOLAR NEED
No. A small light bulb as a size of 222 requires about 2.25 volts and 0.25 amps. Calculators volts need a partner, but only 0.000010 amps around. High Current (crystalline silicon) cells that about 0.3 volts each, so it would have 7 or 8 cells to the N series make the required 2.25 volts. The surface of cells that determines the maximum current. A cell can produce square inch 0.2 to 0.5 amps, depending on the quality of the cell. You might think about replacing the lamp with a white LED. They need about 3 volts, but only 0.02 amp for full performance, and give a white light (at a lower intensity) at much lower currents. Cells such a small area will illuminate these. – Regards, John Popelish
