Q:How do solar panels work?
light from the sun hits the atoms and excites the electrons. This knocks the electrons out of the atom and then the electrons travel in a certain direction. This is the basics of electricity... flowing electrons. And so there's your direct current. I'm sure you could find out more by googling how do solar panels work
Q:Nuclear reactors vs. Solar panels?
You should research nuclear reactors and their emissions. Mostly it's waste heat, and if they use a water-based cooling reactor, there can be significant emissions of water vapor. Some might consider the spent fuel an emission too. Waste nuclear material disposal is a problem. Research it. Solar panels have no emissions during operation, but there is some nasty stuff emitted when they are manufactured. 2: Maintenance of solar panels is pretty straightforward: keep them clean, trim overhanging trees, shrubs, etc., check for and clean corrosion, contaminants, etc. regularly. Maintenance of nuclear power plants, so far, is a full time job for many technicians and engineers. The recently developed portable (the size of a shed) nuclear generators claim zero maintenance for 20+ years. That's a big improvement.
Q:How many solar panels would I need to power my washer machine?
P(Watts) = I(Amps) x V(Volts) Power = 9.6 x 20 Power = ,52 Watts. Therefore you would require 6 x 208Watt solar panels to power the machine on a clear bright day, many more on a cloudy or dull day. Sorry to be a little rain cloud!
Q:would a lazier work on a solar panel?

Q:Has anyone used portable solar panels for home use?
portable panels are too small to be much use for a modern household. A panel appx 20 inches square might supply a laptop computer... but it won't keep your refrigerator running.
Q:Solar Panel System companies at the swapmeet?
Hard to say. Solar panels are becoming more common these days. May want to ask if the vendor is licensed and bonded contractor (if he's doing installation as well as panel sales). Find out the name of the equipment that this guy is selling (panels and other hardware) and do a search. For that matter, get the guys name and do a search on it to see he pops up elsewhere.
Q:how much money does solar panels save?
Your school spend $0,000 per month or per year?? Photovoltaic (Solar Panel) panels have a really large initial capital investment. If you live in a location (e.g. West Coast Desert, SoCal) where there are many sunny days so you might be able to break even quicker. Also note ,there are state and federal grants that can help ease the capital cost. Energy demand keeps going up so expect our current rates to double. People who have alternative forms like wind and solar will have the advantage when this time comes. Just think of when the US had it's oil crisis in summer of 2008, people with small efficient vehicles such as Prius's didn't feel the price increase like the people who bought cheaper large SUV's.
Q:What are the main components of a solar panel?
Solar water heater consists of solar vacuum tube,water storage tank,supports and other accessories.solar vacuum tube is the key component of a solar water heatert,it absorbs sunlight and convert it to heat energy which heat water in the vacuum tube,hot water rises up,cold water fall down,such natural circution make water hot in the water tank.
Q:how do you make solar panel?

Q:are solar electric panels viable in the northwest?
The key is the average insolation value for the location. This is a number that represents the effective numbers of sunlight available per day. The insolation for Seattle varies from 2.9 and 3.57, depending on who is reporting the number. The insolation where I live, near San Francisco is 5. For me, solar is paying off.
