Q:Can someone tell me about solar panels for homes?

Q:can i use 00 ohm /4 watt resister for 5v coming direct from solar panel?
Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.
Q:What about solar panels?
This is a site that can help you estimate the size and number of panels that will power what you intend to provide for. There are plenty of sites selling the panels, so compare prices. Also, check whether your state is offering the rebate like the state of CA is and what the restrictions, terms and conditions are. Even with the rebates they are very costly, so be certain to calculate the pay off period for your application to see whether it is a cost efficient option for your energy usage.
Q:how does a solar panel works?
Kinetic energy of the solar photons in the 'light', hit the surface of the compound, displacing the molecular components in it, creating a flow of energy carrying corpuscles down the wire. These - collected at the end of this circuit - produce energy sufficient to cause movement via the magnetic fields they cross on the either natural or electrically induced magnets they pass through. Basic principles to have in mind, is that these panels only produce ONE type of energy: direct. From one side (+) to another (-), and you must follow this principle when connecting. My suggestion is find the supplier and get instructions. They usually have detailed information. In order to hook up this panel, you must follow instructions.
Q:How energy-productive are solar panels, compared to natural gas?
Solar panels are not nearly as energy productive as natural gas. Case in point how many natural gas fired calculators do you have on your desk? or how many solar fired fireplaces do you know of? Solar panels are a great complement to natural gas/fossil fuel burning sources of fuel though. The more energy you consume from renewable sources of energy (i.e solar, wind, etc) the less you are consuming from non-renewable sources such as natural gas. Solar panel's rate of producing electricity depends on many different variables. Are the panels in direct sunlight? (with no trees or shrubs blocking the panels) There are panels out there made by Kyocera for example that are 85 watts, 65 watts, 50 watts. You should talk with a Professional about this. Look into Sun Electronics as I know that their website has a solar calculator and other helpful tools for interested parties. Good Luck
Q:Who will remove solar panels?
If it is your own installation, you simply reverse the method of your own installation. If your sunlight panel is set up by using a vendor or a contractor, you need to speak to them for the cost of removing your thermal sunlight panel.
Q:how often do you have to replace solar panels?
I have several friends that have large systems down in Mexico where there is no electric grid. They have had these systems for years. They say you probably should plan on at least 0 years with decent output. The capacity does taper off with time so maybe half power in 5 years might be a good assumption. Here in Arizona our payback (Break even) point is about 8-9 years. Our state has subsidies along with fed, and utility company. A 3000 watt system will cost about $0,000 installed. That is about half off regular price.
Q:How can I adapt an automotive reglator to a solar panel?
solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
Q:Solar Panels for home use?
For a starter you would look at how many watts you use. And how deep in you want to go. 80 watts at 2volts dc is nice.. But getting it to 20 ac. You will need a good inverter, battery's. There is things that you can replace in your house that will run on 2 volts. Lights fans. But to answer your question you would first have to look at what you use or and what you want to change over. I have got 900 watts of panels and 2700 Amp hours of battery's on one system. That will run all my lights computers and TVs Also on this I have converted a ups for the 20 VAC. I have been working on this for 0 plus years with no plans to finish. ( there is no end for what you can do with the power of the sun)
