Q:I need a list of worldwide solar panel manufactures from china, US, Spain, Germany, Japan etc...Can any one direct ne to such place?I rather it will also contain comparison of parameters like efficiacy, quality etc and to be divedied by country of manufacturing.Thank you: You can't buy at that level unless you are connected to governement. A lot of production is already spoken for for years to come. Where you live determines what you can legally buy and install. The EU has it's own certification, the US has 2 sets, the Canadians have their own. Your answer also requires knowing the use for the solar panels, whether it is grid-tie, off-grid or standalone to power an appliance. And you have to choose mono crystalline, poly crystalline, or thin-film.

Q:How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?: New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link

Q:260 watt solar panels on an rv?: There are many other controllers, you just need to get a sense for the limitations and make sure you are working within them. Controllers are not that hard to hook up, two connections simply go to the battery, plus and minus. Then the other two go to your panel. I like to put a switch at the panel output, leave it off while you are hooking up the panel side wiring of the controller, then when you are sure everything is connected properly, and you have some kind of battery power indicatioon at the controller, throw on the panel switch and see if it is charging. Remember that a panel is a power source, and connecting it to the controller while it is in the sun is like hooking up a car headlight while the lights are turned on. Another option is to wrap the panel in a blanket and put it in the shade while you are connecting it up. Your panel has a max amp rating, Imax, which will likely be around 5 or 6 amps at that voltage and wattage. Number 4 romex will work for that, as well as medium duty AC extension cord wire, if your run is less than 30 feet or so. Take care Steven, Rudydoo

Q:Can solar panels be installed on a data center or technology facility?: Yes, solar panels can be installed on a data center or technology facility. In fact, many data centers and technology facilities are increasingly adopting solar power as a way to reduce their carbon footprint and lower energy costs. Solar panels can be installed on the rooftops or open spaces surrounding these facilities to generate clean, renewable energy that can be used to power their operations. Additionally, the excess energy produced by the solar panels can even be fed back into the grid, providing an additional source of revenue for the facility.

Q:okay so im lookin 4 an article which explains how practical, wokable, feasible solar panels are. only positive points please :) give me the link. PLZ HELP!!!!: Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy.

Q:how to market solar energy products?: You'd better build some sample project. For e.g, if you mean solar water heater, install one pc on your roof, and make it generate hot water, and tell people about it.

Q:OK, so if you put solar panels up on a roof, they are busy turning the sun's energy into electricity. So, does that mean the roof (and therefore the house/structure) stays cooler as well? Or does it still get hot, because . . . I dunno, maybe the panels don't convert all the energy, and the spillover still heats up the building.Any links or URLs to scientific answers would be appreciated, but I don't mind hearing from the Average Joe or (Joelle).: it would depend on the type of paneling. And compared to what. Since it absorbs solar energy, that includes some heat. Compared to white paint, which may reflect more of the heat, it depends.

Q:Can solar panels be installed on schools or educational institutions?: Yes, solar panels can be installed on schools or educational institutions. In fact, many schools have already adopted solar energy as a sustainable and cost-effective solution. Installing solar panels on educational institutions not only reduces their carbon footprint but also provides valuable educational opportunities for students to learn about renewable energy.

Q:where to find used solar panels?: That's not a good idea. Solar panels wear out, and you probably won't know how worn out they are until you buy them and install them. Which is a little bit too late for most refunds. Your best bet if you're dead set on being foolish, is probably some place like craigslist.

Q:Do I need some type of regulator when the batteries are fully charged.?? The Arco Panels voltage is approx 7VDC at 2.5 amps, Should I limited the voltage to 4VDC???. I would like to connect both panels to up to five batteries at one time...???: You can buy Solar Charger Regulators. I don't. These chargers limit the charging current to the batteries, so you do not get a full efficiency of the solar panel. They disconnect the batteries from the user side (the bulbs you use) if the battery voltage goes below a certain level (i.e. below 8V for a 2V battery), so you cannot use all the power available in the batteries, even in emergency. They introduce, at least, a 0.7V loss (diode forward voltage) between the panel and the battery. If you have SEVERAL panels and a lot of batteries, use a controller as above. If you only have one panel, insert a 5A trip fuse in line (in your case: twice the current of the panel), and a 0-20A diode in series between the panel and the batteries (Kathode side of the + of the battery, Anode side of the + of the panel). Install a voltmeter across the battery. The fuse will prevent any short or over-charge current. The diode will prevent the battery to discharge into the panel at night if it is not already protected. The voltmeter will allow you to watch the status. Your thought of limiting the voltage is useless: should the battery be low, the panel will drop its voltage, limited by the max current. Should the battery be fully charged and the solar panel at full efficiency, it will just try to charge the battery more. A bit of bubbles may result, hence the voltmeter to watch over it. If you want to limit the voltage to 4V, put a 4V Zener (4Vx2.5W!) in series with a resistor of, say, 7V-4V/2.5A or ~ Ohm, 5W, in parallel with the panel.
