Q:in a solar panel, where do the protons go?
Here okorder.com/... Within this structure, the electrons are not really lost from the system. An electron just gets enough energy (from light) to be able to leave its atom, and float freely around the structure. Hence you have electrons in motion, which is the definition of electric current. If the lights go out, the electrons just settle back into one of the atoms that is missing an electron.
Q:How do you make your own solar panels?
If you're thinking of solar electric panels then forget it. It you just want to dabble in solar power then shop around for a 5 volt panel. Find out how many watts it puts out and then divide the cost $$ by the wattage. The lower the cost per watt the better of a deal you'll be getting That's generally speaking of course because it doesn't take quality into account but it's a practical way to compare panels. On the other hand, it you want to make a solar panel that will heat hot water then it's a different story. You can have a lot of fun with that project and you'll find a lot of plans on the Internet.
Q:Is there any way I can get solar panels with my restrictions?
Nope; I see no escape. Best advice I can give is this: sell out and move to a single home residence that has no HOA. If you want solar, I believe the main roofline should run east-west, so that the south exposure of the roof can be easily and economically populated with panels. APS is better than SRP wrt solar ....maybe. Im not sure, everythiong around here is APS so there's no balance. Ive occasionally heard rumors from SRP folks who are unhappy.... check into it before you buy.
Q:How to build a solar panel for lighting/heat source?
Make okorder.com
Q:Solar panels for security cameras?
Only okorder.com/... Each battery will will need to be enclosed in a box from the weather to preserve it as well as the charge controllers. All this work can be done with success, but will be costly if that's what you want, and want it done right. You have no short cuts around this unless you want to damage your cameras? I still say it would be much easier to run conduit under ground for your power supply to each camera, and it would cost less money and time.
Q:Can you tie small-scale solar panel system into household electrical system?
Grid tie inverters are expensive, but you might find a used one cheap on E-Bay, Crags list. Almost any grid tie inverter will work as you are thinking low power, but it likely needs to be 50 hertz or 60 hertz, which ever you have, and 230 volts ac or 20 volts ac which ever you have. It will work for a range of dc voltages, so your solar panels need to produce voltage near the center of that range. I considered buy the 3 PV panel set of 5 watt panels that Harbor freight sells. but I did not determine if the three panels can be conveniently connected in series to produce about 50 volts at light loads, or 00 volts if you buy two sets. You probably do not need the load controller, that comes with each set. I think most grid tie inverters automatically adjust to the dc voltage you supply them, unless it is below some minimum such as 50 volts. It is illegal to connect ordinary inverters to the power company, but they will probably not notice a small system unless you burn your house down. Most inverters will phase lock with the power companies frequency, but they are not designed to do that, so bad is likely unless you connect a resistor such as 0 ohms at 00 watts in series with the ac out of the inverter. If the resistor smokes you should disconnect promptly, then try again to see if you can get phase lock quickly. No smoke, likely means you are one of about 000 co-generators on the electric grid, You can short out the resistor with short piece of very fine wire which will hopefully melt if something goes wrong, such as the power company not sending electricity for 0. seconds or longer. Nearly all inverters have an over load feature, so the thin wire is a back up. Please be careful as people sometimes don't survive an electric shock at 20 volts.
Q:Solar panel question..?
Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
Q:solar panel help needed ?
You need to know how many solar cells are in the panel and what is the rated current each cell will produce. This information should be listed on the panel. Each cell will produce from 0.5 to 0.55 volts DC per cell and each cell will produce a current that is dependent on the size of the cell and the type of material the cell is made from. If the cells are connected in series then the voltage of each cell will add together, that is if you have 30 cells connected in series they should generate about 5 to 6.5 volts DC. If each cell generates .2 amps, then you multiply the voltage of 5 volts DC times .2 amps DC equals 8 watts of power. The current of each cell does not add together when you connect the cells in series only the voltage of each cell. If you connect the 30 cells in parallel then the current of each cell adds together but the voltage of each cell does not. That is 0.5 Volts DC times 36 amps equals 8 watts. The power (watts) produced will be the same. See our blog on the products page to see how to connect solar cells in series and in parallel. We also have a PDF file of solar cells and their rated output current sorted by watts per area and their manufacturer.
Q:what is a solar panel?
The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths. An array is an assembly of solar-thermal panels or photovoltaic (PV) modules; the panels can be connected either in parallel or series depending upon the design objective. Solar panels typically find use in residential, commercial, institutional, and light industrial applications. Solar-thermal panels saw widespread use in Florida and California until the 920's when tank-type water heaters replaced them. A thriving manufacturing business died seemingly overnight. However, solar-thermal panels are still in production, and are common in portions of the world where energy costs, and solar energy availability, are high. Recently there has been a surge toward large scale production of PV modules. In parts of the world with significantly high insolation levels, PV output and their economics are enhanced. PV modules are the primary component of most small-scale solar-electric power generating facilities. Larger facilities, such as solar power plants typically contain an array of reflectors (concentrators), a receiver, and a thermodynamic power cycle, and thus use solar-thermal rather than PV.

Q:How many wind turbines and solar panels does the world need to replace coal, oil and nuclear power?
Both the wind turbines ( windmills) and solar panels are less costly to implement than nuclear power and have less disaster potential. They have proven that Windmills miles out in the ocean are a great source of power. This dose not consume any land. For land bound areas they should use public roadways to line the windmills. For areas without sustainable winds they can use the combined effect of windmills and solar power. Honey, any motor needs oil. Whether it is a generator for a windmill or a nuclear reactor. Motors are what runs the world. Consider the amount of oil to run a nuclear facility. Tons more than a generator motor. Once a turbine is activated (motor started) the winds themselves turns the windmill. Each turbine is lined up with the next (wind farms) to push wind at the blades, they each push each other.
