Q:how much power do i need from my solar panels?
you must consider what electrical appliances you want to use, eg. do you have an electric stove? clothes dryer? air conditioner? heater? watts are watts, solar panels are used to create d.c. electricity which is stored in batteries then inverted to a.c. household electricity the d.c. batteries are usually 36 to 48 volts then this is converted to 20 volt a.c. when you figure out the watts being consumed in your household you size your batteries and inverter to these requirements. on your current electric bill you should see a charge for kwh, kilowatt hours= watts in thousands x hours. If you use 25 kwh per month your house is using 35 watts per hour x 720 hours in a month. you would then want sol.ar panels that charge at least 70 watts per hour because roughly half of the day it's dark depending on where you live December is even less of course in the northern hemisphere. Your batteries need to have capacity to hold a days worth of power, batteries are rated in amp hours, amp hours x volts = watt hours. I hope this points you in the right direction. All of this being said be sure to buy your system from a reputable dealer, someone with experience and good references. I am an electrician and have seen systems put in that are completely worthless because they were not sized properly and It sucks to see that someone paid $30k or more for something that is completely useless, it sucks even more when they ask me to help them and I say pay another $30k to up size the system to what they need. Remember you don't get anything for nothing so be prepared to spend money initially and be prepared to be live very energy conscious in your day to day life. Good luck

Q:Silicon, Polychristaline, or Solar Panel?
Let me help you get an idea of what you are talking about as your notes seems a bit jumbled. Mostly when they refer to a silicon solar cell they mean that the silicon is one crystal of silicon. (very much like a diamond, but with atoms of silicon instead of carbon). A single perfect crystal of silicon can be grown that is very large at temperatures near the melting point of silicon or around 400C and then is sawed up to create electronics or solor cells. Polycrystalline :) solar cells are also made of silicon, but instead of a single crystal it is made of a jumble of small crystals that have different sizes and directions. So these types of solar cells can be made using a silicon gas (siline: SiH4) at much lower temperatures 600-700C. So these are less expensive to make, but because they are not perfect crystals a poly solar panel that is the same size as a crystalline solar panel will make less energy. I hope that helps.
Q:What ever happened to solar powered panels?
The technology did not die out. It is in fact quite alive and well, and there exist many different manufacturers of solar panels and devices utilizing them. The problem is that the technology has not yet advanced sufficiently to generate large amounts of power with solar panels, at least not with panels of any practical size and weight. You can easily buy a panel which will trickle-charge your car's battery during the day, but nothing that can generate anywhere near the power required to actually move a car's mass at any significant speed. You would need to buy panels with a very large surface area to make any significant amount of power, and these panels would be very heavy and very expensive.
Q:Are solar Panels worth it?
The answer is yes. Where it used to cost around $0 per watt you can now buy a system installed for half of that. Panels are more powerful, technology is better so once again the answer is yes. In addition a lot of power companies are offering net metering programs (that is where you sell your extra power back to them for credit). It's like putting power in the bank during peak solar days to use when the sun doesn't shine. You stay hooked up to the grid and when you're making more than you're using your meter spins backwards.
Q:SOLAR PANELS (sun enerjy)?
Grid-tied solar systems in the U.S. run at least $8/watt installed. To completely run a 2,000 sq ft home, you'd need about 50 amps service from solar -- both 20 volts and 240 volts. Not very practical. Panels are expensive, but the BOS (balance of system) is as well. You need mounts to bolt the panels to the roof (same thing if ground mounted). Cable, wire, and connectors will run several hundred dollars. A couple of grid-tie inverters in the range of 4,000 watts each will cost you several $6,000 to $8,000, plus sub panels, combiner boxes, breakers, disconnects, charge controls, and batteries, among other things. You'd likely need 5 to 24 panels, depending on too many factors to mention here. You'd need at least 8 batteries, likely 2 volt ones, probably more if you want to run the entire home from solar. Solar (or wind) systems have to be installed in the U.S. by state licensed installers, and there are not many of those yet. And if you grid-tie the system, you'll need to put an interconnection agreement in place with your local utility, plus the utility will have requirements on the net-metering and installation of a switch they can use to turn your solar system off from the grid. And this would not produce hot water in the way you are thinking. If you have an electric hot water heater now, the solar system could help run that, just like the rest of your home. Hot water from solar and electricity from solar are two completely different technologies.
Q:Is there anyone trying to create a cheaper and more efficient solar panel?
The cheapest will be solar paint where you lay down some wires and paint the panel on. Solar roof tiles are also coming along but each tile has to be wired in. Currently the target is $ a watt. The efficiencies of these panels are very low but if the cost is low enough then the efficiencies won't matter. Keep in mind that even fossil fuel is solar power, just solar power captured by photosynthesis millions of years ago, and photosynthesis has a maximum theoretical efficiency of 6.6% with most plants achieving less than % efficiency so even an inefficient solar paint already outstrips our current energy sources in terms of efficiencies. The real problem is the business model. With solar energy you can sell the panels upfront but then what do you do for an income whereas with fossil fuels, you sell every kwh and bill each month.
Q:Solar panel setup?
You have to keep the polarity straight. Red is positive + Black is negative - I don't know how much amperage you are drawing, or how many amps the solar panel puts out. This charge controller is a device I am unfamiliar with- What does it say on it? how many volts? how many amps?
