While solar cells can be placed on the roofs of existing structures or in otherwise unused areas, we will simply use existing real estate prices to estimate costs.
These solar cells have held the world efficiency record for converting sunlight into electricity for more than a decade and last year achieved an efficiency of 24.

Solar photovoltaic cells have helped in man's quest in the exploration of the universe by powering the first space craft to leave our solar system and enter intergalactic space.
Thin film solar cells are about 50 times thinner than crystalline solar cells and are easier to make.
Solar cells cover the entire flat-plate module area and are uniformly illuminated with unconcentrated sunlight, as shown to the right.

Solar cells are solid state devices in which photons, basic packets of light, collide with atoms and transfer their energy to electrons.
PV or Solar cells operate on the principle that electricity will flow between two different semiconductors when they are put in contact with each other and exposed to light.
Solar electricity science fair projects can be performed using inexpensive solar cells as provided in our solar electricity kits or other sources.
