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:its about solar panels?
If solar power is not practical, why do four of my friends and I have it? Actually Don M is mostly right. The factors to consider when contemplating a solar installation are numerous. For example my system will not pay for itself in utility savings in my lifetime, but I plan to sell the house soon. What I am saving on electricity costs, and the increased amount I can ask a buyer, I will come out well ahead. Cruise the Internet and look in the green search box at the top of this page, for solar panels. As you learn more, you can come back with more questions.
Q:Solar panels and your opinion?
You ask a great question, because this should really be a financial decision, and not only an environmental one. Depending on which state you live in, the payback on a system is often in the 5 to 2 year range. The great thing about solar panels is that the fuel source is free and you don't need to speculate on your future costs. You pay for the equipment up front, and then you just enjoy the free power. Most solar panel systems last at least 30 years, so compare the cost of solar panels to paying your average electric bill 360 times. And that does not include any inflation of energy cost increase. Check out our website to learn more.
Q:why aren't solar panels for your house more affordable?
Best okorder.com/... Of course sometimes you can get very cheap solar panels if you are in the right place at the right time... A friend of mine got the solar array from one of the road service companies... it had some minor defect so they were replacing it and throwing away the defective one... it still put out a good bit of power and it was free for him... but that is all luck.
Q:Solar Panel Question?
It depends very much on where you live. If you live in Nevada, Arizona or California solar panels might be a good idea. If you live in Canada don´t expect to get your bill to zero... 800 kwh/month means an average consumption rate of about 2500 watts. 6 panels would cover that. But your energy consumption isn´t cosntant and nor is your energy production from the solarpanels. If you go off to work during the day when your panels produce the most then you probably produce excess electricity. Check with your utility if it is possible for you to sell off that electricity by putting it on the grid. Then you buy back electricity when you´re watching tv and surf the web at night. You loose money and electricity like this (or by using batteries as suggested above) so I would underdimension my solarpanel capacity. It makes sense if it is cheaper to just buy electricity at night. The retailer and the manufacturer should have charts showing how much their 65 watt panels really produce at different times of the day and the year for your location. Oh, and I´m sure there are ways in which you could reduce your electricity consumption. Smart lights, energy efficient lights are easy ways.
Q:What is the best solar panel?
You have to decide which is more important to you, cost or efficiency. The most efficient solar panels that are commercially available cost more than twice as much per square foot than the cheapest ones. Ultimately, I believe that the cost per watt was actually better on the cheaper, least efficient panels, but then you need a lot of square footage in order to generate any substantial power. So it comes down to what you have more of, space or money. The new panels that collect a wider range of light are not currently available commercially, and when they are I am sure that they will be expensive. I have read the research but have not heard of anyone mass producing them yet.
Q:Is using a thick cardboard backing for a solar panel ok?
In commercial panels some sort of polymer is often used for backing. With a 2V panel there are 36 cells, which means they can still output about 4V for charging a 2V battery even when hot. The voltage reduces about 2.2mV per degree C per cell. Commercial panels are meant to work up to about 60 degrees C, which is quite normal in the sun. I have found just lying them on the grass the air circulation is reduced, and they get too hot to charge a 2V battery. This means the backing should have good thermal conductivity while being an electrical insulator, as well as mechanical strength. The cells are often encapsulated in a thermosetting plastic first, then laid face down so a liquid polymer can be poured as backing.. I have removed commercial panels from their frames and re-packaged them to work in a very wet environment. I suppose cardboard would work, but it is unlikely to have good cooling so the expected voltage would be lower. As you intend to only operate indoors I suppose it is unlikely you have full sun most of the time anyway, so there could be less heating and less output current accordingly. I think the cardboard is only useful for a short time, and is not strong enough. Temperature wise it is marginal. The link below uses plywood for the backing. The backing is supposed to provide strength too. A sheet of some sort of plastic or laminate (including melamine laminate as in kitchen bench tops) comes to mind too. The cells are supposed to be bonded to the backing for better thermal conductivity. Use silicon RTV to stick cells to the backing, very thinly.
Q:Can I made my own solar panel?
I don't think it would be very easy to do with household stuff, or even with anything you can find in stores. All I can tell you is that typical electronics LED lights tend to create current when they have light shining on them, but you would need millions for them to be any use.
Q:Solar panel trouble?
you don't need a capacitor. You can connect it to a light directly. Capacitors rarely break. You can check with an ohmeter.
