Q:What is the most powerful solar panel made?
Yeah lead acid is the desirable yet once you've a higher image voltaic setup like 200watts or extra you extremely want a cost controller in addition they favor to be vented because even as they're charged the produce hydrogen that once concentrated burns and is no longer good to respire in. the worst section about lithium ion is they imeadiatly commence to decompose once they're used so that they in straight forward words very last 2-4 years the position lead acid can very last over 2 years if good maintained.
Q:How to connect 2 power supplies together? (Solar panels)?
You have to look at the power output of the cell. The first consideration has to do with voltage. A single cell with no load might output one volt or less. Wiring cells in series would double that output, at least in theory. (Internal resistance will lower the actual voltage.) You've wired the cells in parallel, however. Try unsoldering one electrode and then measure voltage output of each cell. There is still the issue of current output. I don't know if there will be enough with your setup. How many cells are there and what kind of batteries were they charging?
Q:Need some Information about solar panels ?
No. The only coatings I am aware of are those that reduce reflection so more light gets through the protective surface to the actual cells. Anything thing that affects appearance is going to be reflecting light back to the viewer and the photons of that light are not available for electricity or heat. If the appearance of the panels offends you, then they need to be concealed by a fence of panels around them that do not throw shadows on the panels.
Q:how do I become a solar panel contractor?
Q:Will a 3w Solar Panel Charge A 55ah Car Battery?
To charge a 2V lead acid battery, you pretty much have to put almost 24V across it and it's only 50% efficient at charging so if your solar panel does put out 3W, you can expect 3/24/2 or /6th of an amp in usable charging. Therefore, from a flat battery, it would take 55*6 or 880 hours to charge the battery. If you assume about 6 hours of usable sunlight per day, that would be 47 days not taking into consideration the normal leakage that lead acid batteries have. It's quite likely that the leakage rate will be greater than the charging rate and the battery will never charge. You'll need a bigger solar panel.
Q:Is this a good kit for building a solar panel?
Q:Are DIY Solar panels legitimate for saving electricity?
Solar power generation is still in its infancy. Solar panels are incredibly expensive (average of approx $25,000 to equip a house with roof top panels) and are incredibly inefficient. However, the economics and efficiency of solar electricity may evolve into a system of economic, efficient collection systems in time depending on the level of funding available in the future for the necessary research and development. We can only hope.
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:Do I only need solar panels to have energy in day and through the night?
solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.
