A 230 W solar panel providing power for a 270 W projector, meaning that from two hours of sunlight in the daytime we get one and a half hour of film projected at night. We plan on adding panels to the cinema from year to year, so the capacity will grow continually.
For those curious about the efficiency of solarpanels, a 230 W solarpanel at 1,5 squaremeters will produce about 900 times its’ wattage in a year, so:
230×900=207000 or 207 kWh. per year
(and that gives us 767 hours of projected film per year)
solar panel gives regular output whenever the light of sun puts on it.
Good post this is it will also increase the knowledge about solar.
