Q:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:Will a 2W, 2V mono solar panel power up a laptop battery?
I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
Q:Anybody install solar panels themselves?
i have always been interested in it but the storage (batteries) and power grid tie in (to get paid for excess) technicalities made me shy away. since your getting it installed im sure labor is a huge part of that -OKorder has tons of the equipment. I think wind may be a good home renewable source depending on where you live (cheaper than solar if you got the wind and space) I would doubly check any goverment offerings - I know they used to and maybe still do offer sizable credits if you are within the bureacratic standards so make sure the installers work with you on that. good luck -its new - and going to be a hassle to get right but the world needs more like you. willing to pay more now for a better tommorow (and not just $ wise) you should come out ahead as interest rates and market provides little value on that cash and saving any equipment falure you sound good. does the price include the batteries for all your produce kwh's? panels and labor aside batteries are the next big one
Q:How much maintenance do solar panels require?
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:How do you make solar panels?
it takes a ton of them to power a home most only put out 45 watts, [cheaper ones] solar is not cheap its more expensive than electricity
Q:how do solar panels work?
Sunlight hits the solar panel, and DC power is generated. By the power is not stable. It becomes stronger or weaker according to the strength of sunlight.
Q:You place four identical solar panels in 4 places.?
They all face the sun about 50% of the time on average over the year. Best: far side of the moon, 2nd near side of the moon; because in the first case the panel is a moon-orbit-diameter closer to the sun at time of exposure. I think the Sahara and New England come next for reasons already given, in addition to the significant amount of energy absorbed by the atmosphere even to reach the Sahara.
Q:How do I get a grant passed for my school for solar panels?
Excessively long payback schemes for solar panels are being quoted. It depends on where you live, where you situate your solar panels, what you buy and if you get a grant or install them yourself. Much of the cost of Solar panels is in the installation. Any competent DIY person can install a simple solar panel system. Ours cost less than £000 to buy and self install. What are you calling payback time? Because each time I don't use fossil fuels and use solar energy instead, I don't get a 'fossil fuel' bill. Whilst we still use some electricity for running a fridge, lighting etc we have no other fuel bills, no gas, no oil, no electric heating no electrically heated hot water. We have woodburning stoves (which run on free wood) and solar. Remember you are not just paying for the electricity/gas/oil etc that you use, you are also paying standing charges, VAT etc. Include those in your 'payback time figures' and you will see a very different picture. How long would it take you to pay back £,000 if you only had one tiny electric bill each quarter?
Q:What do I need to do to run my dehumidifier from solar panels?
This Site Might Help You. RE: What do I need to do to run my dehumidifier from solar panels? First of all is it possible? I do not know how much electricity my dehumidifier but could someone give me an idea of how much this would cost to do? A link to a solar panel or equipment that would do the job would be nice too. Thanks in advance.
Q:Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port?
