1. Photovoltaics - You point them up, and the photons, using quantum burrito meals, produce DC. Then it goes to an inverter, and then nobody gives a shit.
2. Concentrated photovoltaics - You get like a lens to focus more sunlight...

Solar panels rely on the properties of silicon. You see, silicon (Si on your periodic table) has just four electrons when in its natural state. Of course, a silicon atom actually has room four 8 electrons.
One silicon atom can combine
The public should take pride in the fact that 'their' building they work in produces a 'sum' of solar energy, so why don't skyscrapers utilize this energy?
I agree with you that this should be done. As lawyerslastbreath saw in Las Vegas, those casinos have the $$money and should use it for solar panels.....If they can't afford it who can?
Photosynthesis is used by plants and a semiconductor-based solar cell both harness solar energy. what are three ways these two systems are similar and three ways they are different?
Also what is Thermodynamics and how does it apply...

Solar Impulse moves closer to round-the-world flight - Science
Airborne for almost 90 minutes, test pilot Markus Scherdel guided the graceful single-seat craft to a height of 5,500 feet above the Payerne military airport in Switzerland on Wednesday, while reaching a modest top speed of 28 miles per hour (approximately 45 kph).
“The first flight was for me a very intense moment,” enthused Scherdel after returning the plane safely to the Swiss tarmac. “The HB-SIA behaved just as the flight simulator told us. Despite its immense size and feather weight, the aircraft's controllability matches our expectations.”
Weighing less than a small car and without the support of conventional engines, the Solar Impulse instead relies on four 10HP propeller-equipped electric gondolas that are powered by solar energy harnessed from 12,000 photovoltaic panels covering the plane's enormous wingspan – which rivals that of an Airbus A340 jetliner.
