Project Idea for Solar Energy?

Question

need help for project idea for my science assignment.
have to fit in either POSTER or MODEL.
greatly appreciated.

Answer 1

Build a small solar oven. Build a small plexiglas box with a plexiglas lid that flips open. Line the rim of the lid with rubber stripping, and put a latch on the lid that pulls it against the weatherstripping to form a nice seal. Line the bottom with black construction paper and leave the inside bottom uncovered. Line the sides with aluminum foil to reflect the incoming sunlight and recirculate it. This will warm a plate of food pretty fast on a sunny day. You can even cook simple meals in it, in a few hours, although I wouldn't do chicken or pork .

Answer 2

I would suggest a project which shows how the efficiency of a solar panel is affected by the wavelength of the light hitting it as well as the intensity. Read the Energy Loss in a Solar Cell section in the following link.

Answer 3

Solar cooking

Answer 4

get solar power to light up CFLs in a house...
